+%% pointer to an array of the indicated type in which to place the returned data. 
+%%
+%%  Type conversion is performed if  `Params'  has a different type than the state variable

+%% which are written into the frame buffer. This is the normal mode and also the default
+%% mode. 
+%%
+%% `?GL_SELECT':  Selection mode. No pixel fragments are produced, and no change to
+%% the frame buffer contents is made. Instead, a record of the names of primitives that would
+%% have been drawn if the render mode had been `?GL_RENDER' is returned in a select
+%% buffer, which must be created (see  {@link gl:selectBuffer/2} ) before selection mode is
+%% entered. 
+%%

+%% a feedback buffer, which must be created (see  {@link gl:feedbackBuffer/3} ) before feedback
+%% mode is entered. 
+%%
+%%  The return value of ``gl:renderMode'' is determined by the render mode at the time ``gl:renderMode''

+%% @doc Return error information
+%%
+%% ``gl:getError'' returns the value of the error flag. Each detectable error is assigned
+%% a numeric code and symbolic name. When an error occurs, the error flag is set to the appropriate
+%% error code value. No other errors are recorded until ``gl:getError'' is called, the
+%% error code is returned, and the flag is reset to `?GL_NO_ERROR'. If a call to ``gl:getError''
+%%  returns `?GL_NO_ERROR', there has been no detectable error since the last call to ``gl:getError''
+%% , or since the GL was initialized. 
+%%
+%%  To allow for distributed implementations, there may be several error flags. If any single
+%% error flag has recorded an error, the value of that flag is returned and that flag is
+%% reset to `?GL_NO_ERROR' when ``gl:getError'' is called. If more than one flag has
+%% recorded an error, ``gl:getError'' returns and clears an arbitrary error flag value.
+%% Thus, ``gl:getError'' should always be called in a loop, until it returns `?GL_NO_ERROR'
+%% , if all error flags are to be reset. 
+%%
+%%  Initially, all error flags are set to `?GL_NO_ERROR'. 
+%%
+%%  The following errors are currently defined: 
+%%
+%% `?GL_NO_ERROR':  No error has been recorded. The value of this symbolic constant
+%% is guaranteed to be 0. 
+%%
+%% `?GL_INVALID_ENUM':  An unacceptable value is specified for an enumerated argument.
+%% The offending command is ignored and has no other side effect than to set the error flag.
+%% 
+%%
+%% `?GL_INVALID_VALUE':  A numeric argument is out of range. The offending command is
+%% ignored and has no other side effect than to set the error flag. 
+%%
+%% `?GL_INVALID_OPERATION':  The specified operation is not allowed in the current state.
+%% The offending command is ignored and has no other side effect than to set the error flag.
+%% 
+%%
+%% `?GL_INVALID_FRAMEBUFFER_OPERATION':  The framebuffer object is not complete. The
+%% offending command is ignored and has no other side effect than to set the error flag. 
+%%
+%% `?GL_OUT_OF_MEMORY':  There is not enough memory left to execute the command. The
+%% state of the GL is undefined, except for the state of the error flags, after this error
+%% is recorded.

+%% indicating the behavior to be controlled, and  `Mode'  is another symbolic constant
+%% indicating the desired behavior. The initial value for each  `Target'  is `?GL_DONT_CARE'
+%% .  `Mode'  can be one of the following: 
+%%
+%% `?GL_FASTEST':  The most efficient option should be chosen. 
+%%
+%% `?GL_NICEST':  The most correct, or highest quality, option should be chosen. 
+%%
+%% `?GL_DONT_CARE':  No preference. 
+%%
+%%  Though the implementation aspects that can be hinted are well defined, the interpretation
+%% of the hints depends on the implementation. The hint aspects that can be specified with  `Target' 
+%% , along with suggested semantics, are as follows: 
+%%
+%% `?GL_FRAGMENT_SHADER_DERIVATIVE_HINT':  Indicates the accuracy of the derivative
+%% calculation for the GL shading language fragment processing built-in functions: `?dFdx'
+%% , `?dFdy', and `?fwidth'. 
+%%
+%% `?GL_LINE_SMOOTH_HINT':  Indicates the sampling quality of antialiased lines. If
+%% a larger filter function is applied, hinting `?GL_NICEST' can result in more pixel
+%% fragments being generated during rasterization. 
+%%
+%% `?GL_POLYGON_SMOOTH_HINT':  Indicates the sampling quality of antialiased polygons.
+%% Hinting `?GL_NICEST' can result in more pixel fragments being generated during rasterization,
+%% if a larger filter function is applied. 
+%%
+%% `?GL_TEXTURE_COMPRESSION_HINT':  Indicates the quality and performance of the compressing
+%% texture images. Hinting `?GL_FASTEST' indicates that texture images should be compressed
+%% as quickly as possible, while `?GL_NICEST' indicates that texture images should be
+%% compressed with as little image quality loss as possible. `?GL_NICEST' should be
+%% selected if the texture is to be retrieved by  {@link gl:getCompressedTexImage/3}  for reuse.

+%% @doc Operate on the accumulation buffer
+%%
+%%  The accumulation buffer is an extended-range color buffer. Images are not rendered into
+%% it. Rather, images rendered into one of the color buffers are added to the contents of
+%% the accumulation buffer after rendering. Effects such as antialiasing (of points, lines,
+%% and polygons), motion blur, and depth of field can be created by accumulating images generated
+%% with different transformation matrices. 
+%%
+%%  Each pixel in the accumulation buffer consists of red, green, blue, and alpha values.
+%% The number of bits per component in the accumulation buffer depends on the implementation.
+%% You can examine this number by calling  {@link gl:getBooleanv/1}  four times, with arguments
+%% `?GL_ACCUM_RED_BITS', `?GL_ACCUM_GREEN_BITS', `?GL_ACCUM_BLUE_BITS', and `?GL_ACCUM_ALPHA_BITS'
+%% . Regardless of the number of bits per component, the range of values stored by each component
+%% is  [-1 1]. The accumulation buffer pixels are mapped one-to-one with frame buffer pixels. 
+%%
+%% ``gl:accum'' operates on the accumulation buffer. The first argument,  `Op' , is
+%% a symbolic constant that selects an accumulation buffer operation. The second argument,  `Value' 
+%% , is a floating-point value to be used in that operation. Five operations are specified: `?GL_ACCUM'
+%% , `?GL_LOAD', `?GL_ADD', `?GL_MULT', and `?GL_RETURN'. 
+%%
+%%  All accumulation buffer operations are limited to the area of the current scissor box
+%% and applied identically to the red, green, blue, and alpha components of each pixel. If
+%% a ``gl:accum'' operation results in a value outside the range  [-1 1], the contents of an
+%% accumulation buffer pixel component are undefined. 
+%%
+%%  The operations are as follows: 
+%%
+%% `?GL_ACCUM':  Obtains R, G, B, and A values from the buffer currently selected for
+%% reading (see  {@link gl:readBuffer/1} ). Each component value is divided by   2 n-1, where  
+%% n is the number of bits allocated to each color component in the currently selected buffer.
+%% The result is a floating-point value in the range  [0 1], which is multiplied by  `Value' 
+%% and added to the corresponding pixel component in the accumulation buffer, thereby updating
+%% the accumulation buffer. 
+%%
+%% `?GL_LOAD':  Similar to `?GL_ACCUM', except that the current value in the accumulation
+%% buffer is not used in the calculation of the new value. That is, the R, G, B, and A values
+%% from the currently selected buffer are divided by   2 n-1, multiplied by  `Value' ,
+%% and then stored in the corresponding accumulation buffer cell, overwriting the current
+%% value. 
+%%
+%% `?GL_ADD':  Adds  `Value'  to each R, G, B, and A in the accumulation buffer. 
+%%
+%% `?GL_MULT':  Multiplies each R, G, B, and A in the accumulation buffer by  `Value' 
+%%  and returns the scaled component to its corresponding accumulation buffer location. 
+%%
+%% `?GL_RETURN':  Transfers accumulation buffer values to the color buffer or buffers
+%% currently selected for writing. Each R, G, B, and A component is multiplied by  `Value' 
+%% , then multiplied by   2 n-1, clamped to the range  [0 2 n-1], and stored in the corresponding
+%% display buffer cell. The only fragment operations that are applied to this transfer are
+%% pixel ownership, scissor, dithering, and color writemasks. 
+%%
+%%  To clear the accumulation buffer, call  {@link gl:clearAccum/4}  with R, G, B, and A values
+%% to set it to, then call  {@link gl:clear/1}  with the accumulation buffer enabled.

+%% @doc Execute a list of display lists
+%%
+%% ``gl:callLists'' causes each display list in the list of names passed as  `Lists' 
+%% to be executed. As a result, the commands saved in each display list are executed in order,
+%% just as if they were called without using a display list. Names of display lists that
+%% have not been defined are ignored. 
+%%
+%% ``gl:callLists'' provides an efficient means for executing more than one display list.  `Type' 
+%%  allows lists with various name formats to be accepted. The formats are as follows: 
+%%
+%% `?GL_BYTE':  `Lists'  is treated as an array of signed bytes, each in the range  
+%% -128 through 127. 
+%%
+%% `?GL_UNSIGNED_BYTE':  `Lists'  is treated as an array of unsigned bytes, each
+%% in the range 0 through 255. 
+%%
+%% `?GL_SHORT':  `Lists'  is treated as an array of signed two-byte integers, each
+%% in the range   -32768 through 32767. 
+%%
+%% `?GL_UNSIGNED_SHORT':  `Lists'  is treated as an array of unsigned two-byte integers,
+%% each in the range 0 through 65535. 
+%%
+%% `?GL_INT':  `Lists'  is treated as an array of signed four-byte integers. 
+%%
+%% `?GL_UNSIGNED_INT':  `Lists'  is treated as an array of unsigned four-byte integers.
+%% 
+%%
+%% `?GL_FLOAT':  `Lists'  is treated as an array of four-byte floating-point values.
+%% 
+%%
+%% `?GL_2_BYTES':  `Lists'  is treated as an array of unsigned bytes. Each pair of
+%% bytes specifies a single display-list name. The value of the pair is computed as 256 times
+%% the unsigned value of the first byte plus the unsigned value of the second byte. 
+%%
+%% `?GL_3_BYTES':  `Lists'  is treated as an array of unsigned bytes. Each triplet
+%% of bytes specifies a single display-list name. The value of the triplet is computed as
+%% 65536 times the unsigned value of the first byte, plus 256 times the unsigned value of
+%% the second byte, plus the unsigned value of the third byte. 
+%%
+%% `?GL_4_BYTES':  `Lists'  is treated as an array of unsigned bytes. Each quadruplet
+%% of bytes specifies a single display-list name. The value of the quadruplet is computed
+%% as 16777216 times the unsigned value of the first byte, plus 65536 times the unsigned
+%% value of the second byte, plus 256 times the unsigned value of the third byte, plus the
+%% unsigned value of the fourth byte. 
+%%
+%%  The list of display-list names is not null-terminated. Rather,  `N'  specifies how
+%% many names are to be taken from  `Lists' . 
+%%
+%%  An additional level of indirection is made available with the  {@link gl:listBase/1}  command,
+%% which specifies an unsigned offset that is added to each display-list name specified in  `Lists' 
+%%  before that display list is executed. 
+%%
+%% ``gl:callLists'' can appear inside a display list. To avoid the possibility of infinite
+%% recursion resulting from display lists calling one another, a limit is placed on the nesting
+%% level of display lists during display-list execution. This limit must be at least 64,
+%% and it depends on the implementation. 
+%%
+%%  GL state is not saved and restored across a call to ``gl:callLists''. Thus, changes
+%% made to GL state during the execution of the display lists remain after execution is completed.
+%% Use  {@link gl:pushAttrib/1} ,  {@link gl:pushAttrib/1} ,  {@link gl:pushMatrix/0} , and  {@link gl:pushMatrix/0}

+%% @doc Delimit the vertices of a primitive or a group of like primitives
+%%
+%% ``gl:'begin''' and  {@link gl:'begin'/1}  delimit the vertices that define a primitive or a group
+%% of like primitives. ``gl:'begin''' accepts a single argument that specifies in which of
+%% ten ways the vertices are interpreted. Taking   n as an integer count starting at one,
+%% and   N as the total number of vertices specified, the interpretations are as follows: 
+%%
+%% `?GL_POINTS':  Treats each vertex as a single point. Vertex   n defines point   n. 
+%% N points are drawn. 
+%%
+%% `?GL_LINES':  Treats each pair of vertices as an independent line segment. Vertices
+%%   2  n-1 and   2  n define line   n.  N/2 lines are drawn. 
+%%
+%% `?GL_LINE_STRIP':  Draws a connected group of line segments from the first vertex
+%% to the last. Vertices   n and   n+1 define line   n.  N-1 lines are drawn. 
+%%
+%% `?GL_LINE_LOOP':  Draws a connected group of line segments from the first vertex
+%% to the last, then back to the first. Vertices   n and   n+1 define line   n. The last
+%% line, however, is defined by vertices   N and   1.  N lines are drawn. 
+%%
+%% `?GL_TRIANGLES':  Treats each triplet of vertices as an independent triangle. Vertices
+%%   3  n-2,  3  n-1, and   3  n define triangle   n.  N/3 triangles are drawn. 
+%%
+%% `?GL_TRIANGLE_STRIP':  Draws a connected group of triangles. One triangle is defined
+%% for each vertex presented after the first two vertices. For odd   n, vertices  n,  n+1,
+%% and   n+2 define triangle   n. For even   n, vertices  n+1,  n, and   n+2 define triangle
+%%   n.  N-2 triangles are drawn. 
+%%
+%% `?GL_TRIANGLE_FAN':  Draws a connected group of triangles. One triangle is defined
+%% for each vertex presented after the first two vertices. Vertices   1,  n+1, and   n+2
+%% define triangle   n.  N-2 triangles are drawn. 
+%%
+%% `?GL_QUADS':  Treats each group of four vertices as an independent quadrilateral.
+%% Vertices   4  n-3,  4  n-2,  4  n-1, and   4  n define quadrilateral   n.  N/4 quadrilaterals
+%% are drawn. 
+%%
+%% `?GL_QUAD_STRIP':  Draws a connected group of quadrilaterals. One quadrilateral is
+%% defined for each pair of vertices presented after the first pair. Vertices   2  n-1,  2 
+%% n,  2  n+2, and   2  n+1 define quadrilateral   n.  N/2-1 quadrilaterals are drawn. Note
+%% that the order in which vertices are used to construct a quadrilateral from strip data
+%% is different from that used with independent data. 
+%%
+%% `?GL_POLYGON':  Draws a single, convex polygon. Vertices   1 through   N define this
+%% polygon. 
+%%
+%%  Only a subset of GL commands can be used between ``gl:'begin''' and  {@link gl:'begin'/1} .
+%% The commands are  {@link gl:vertex2d/2} ,  {@link gl:color3b/3} ,  {@link gl:secondaryColor3b/3} ,  {@link gl:indexd/1} 
+%% ,  {@link gl:normal3b/3} ,  {@link gl:fogCoordf/1} ,  {@link gl:texCoord1d/1} ,  {@link gl:multiTexCoord1d/2} 
+%% ,  {@link gl:vertexAttrib1d/2} ,  {@link gl:evalCoord1d/1} ,  {@link gl:evalPoint1/1} ,  {@link gl:arrayElement/1} 
+%% ,  {@link gl:materialf/3} , and  {@link gl:edgeFlag/1} . Also, it is acceptable to use  {@link gl:callList/1} 
+%%  or  {@link gl:callLists/1}  to execute display lists that include only the preceding commands.
+%% If any other GL command is executed between ``gl:'begin''' and  {@link gl:'begin'/1} , the error
+%% flag is set and the command is ignored. 
+%%
+%%  Regardless of the value chosen for  `Mode' , there is no limit to the number of vertices
+%% that can be defined between ``gl:'begin''' and  {@link gl:'begin'/1} . Lines, triangles, quadrilaterals,
+%% and polygons that are incompletely specified are not drawn. Incomplete specification results
+%% when either too few vertices are provided to specify even a single primitive or when an
+%% incorrect multiple of vertices is specified. The incomplete primitive is ignored; the
+%% rest are drawn. 
+%%
+%%  The minimum specification of vertices for each primitive is as follows: 1 for a point,
+%% 2 for a line, 3 for a triangle, 4 for a quadrilateral, and 3 for a polygon. Modes that
+%% require a certain multiple of vertices are `?GL_LINES' (2), `?GL_TRIANGLES'
+%% (3), `?GL_QUADS' (4), and `?GL_QUAD_STRIP' (2).

+%%  Normals specified with ``gl:normal'' need not have unit length. If `?GL_NORMALIZE'

+%% @doc Set the current color

+%% variants: ``gl:color3'' and ``gl:color4''. ``gl:color3'' variants specify new red,
+%% green, and blue values explicitly and set the current alpha value to 1.0 (full intensity)
+%% implicitly. ``gl:color4'' variants specify all four color components explicitly. 
+%%
+%% ``gl:color3b'', ``gl:color4b'', ``gl:color3s'', ``gl:color4s'', ``gl:color3i'',
+%% and ``gl:color4i'' take three or four signed byte, short, or long integers as arguments.
+%% When `v' is appended to the name, the color commands can take a pointer to an array
+%% of such values. 
+%%
+%%  Current color values are stored in floating-point format, with unspecified mantissa and
+%% exponent sizes. Unsigned integer color components, when specified, are linearly mapped
+%% to floating-point values such that the largest representable value maps to 1.0 (full intensity),
+%% and 0 maps to 0.0 (zero intensity). Signed integer color components, when specified, are
+%% linearly mapped to floating-point values such that the most positive representable value
+%% maps to 1.0, and the most negative representable value maps to   -1.0. (Note that this
+%% mapping does not convert 0 precisely to 0.0.) Floating-point values are mapped directly. 
+%%
+%%  Neither floating-point nor signed integer values are clamped to the range  [0 1] before the
+%% current color is updated. However, color components are clamped to this range before they
+%% are interpolated or written into a color buffer.

+%% @doc Specify the raster position for pixel operations
+%%
+%%  The GL maintains a 3D position in window coordinates. This position, called the raster
+%% position, is used to position pixel and bitmap write operations. It is maintained with
+%% subpixel accuracy. See  {@link gl:bitmap/7} ,  {@link gl:drawPixels/5} , and  {@link gl:copyPixels/5} 
+%% . 
+%%
+%%  The current raster position consists of three window coordinates ( x,  y,  z), a clip
+%% coordinate value  ( w), an eye coordinate distance, a valid bit, and associated color
+%% data and texture coordinates. The   w coordinate is a clip coordinate, because   w is
+%% not projected to window coordinates. ``gl:rasterPos4'' specifies object coordinates   x,
+%%  y,  z, and   w explicitly. ``gl:rasterPos3'' specifies object coordinate   x,  y, and
+%%   z explicitly, while   w is implicitly set to 1. ``gl:rasterPos2'' uses the argument
+%% values for   x and   y while implicitly setting   z and   w to 0 and 1. 
+%%
+%%  The object coordinates presented by ``gl:rasterPos'' are treated just like those of a  {@link gl:vertex2d/2} 
+%%  command: They are transformed by the current modelview and projection matrices and passed
+%% to the clipping stage. If the vertex is not culled, then it is projected and scaled to
+%% window coordinates, which become the new current raster position, and the `?GL_CURRENT_RASTER_POSITION_VALID'
+%%  flag is set. If the vertex `is' culled, then the valid bit is cleared and the current
+%% raster position and associated color and texture coordinates are undefined. 
+%%
+%%  The current raster position also includes some associated color data and texture coordinates.
+%% If lighting is enabled, then `?GL_CURRENT_RASTER_COLOR' (in RGBA mode) or `?GL_CURRENT_RASTER_INDEX'
+%%  (in color index mode) is set to the color produced by the lighting calculation (see  {@link gl:lightf/3} 
+%% ,  {@link gl:lightModelf/2} , and  {@link gl:shadeModel/1} ). If lighting is disabled, current
+%% color (in RGBA mode, state variable `?GL_CURRENT_COLOR') or color index (in color
+%% index mode, state variable `?GL_CURRENT_INDEX') is used to update the current raster
+%% color. `?GL_CURRENT_RASTER_SECONDARY_COLOR' (in RGBA mode) is likewise updated. 
+%%
+%%  Likewise, `?GL_CURRENT_RASTER_TEXTURE_COORDS' is updated as a function of `?GL_CURRENT_TEXTURE_COORDS'
+%% , based on the texture matrix and the texture generation functions (see  {@link gl:texGend/3} ).
+%% Finally, the distance from the origin of the eye coordinate system to the vertex as transformed
+%% by only the modelview matrix replaces `?GL_CURRENT_RASTER_DISTANCE'. 
+%%
+%%  Initially, the current raster position is (0, 0, 0, 1), the current raster distance is
+%% 0, the valid bit is set, the associated RGBA color is (1, 1, 1, 1), the associated color
+%% index is 1, and the associated texture coordinates are (0, 0, 0, 1). In RGBA mode, `?GL_CURRENT_RASTER_INDEX'
+%%  is always 1; in color index mode, the current raster RGBA color always maintains its
+%% initial value.

+%% @doc Select flat or smooth shading
+%%
+%%  GL primitives can have either flat or smooth shading. Smooth shading, the default, causes
+%% the computed colors of vertices to be interpolated as the primitive is rasterized, typically
+%% assigning different colors to each resulting pixel fragment. Flat shading selects the
+%% computed color of just one vertex and assigns it to all the pixel fragments generated
+%% by rasterizing a single primitive. In either case, the computed color of a vertex is the
+%% result of lighting if lighting is enabled, or it is the current color at the time the
+%% vertex was specified if lighting is disabled. 
+%%
+%%  Flat and smooth shading are indistinguishable for points. Starting when  {@link gl:'begin'/1} 
+%% is issued and counting vertices and primitives from 1, the GL gives each flat-shaded line
+%% segment   i the computed color of vertex   i+1, its second vertex. Counting similarly
+%% from 1, the GL gives each flat-shaded polygon the computed color of the vertex listed

+%% @doc Set light source parameters
+%%
+%% ``gl:light'' sets the values of individual light source parameters.  `Light'  names
+%% the light and is a symbolic name of the form `?GL_LIGHT' i, where i ranges from 0
+%% to the value of `?GL_MAX_LIGHTS' - 1.  `Pname'  specifies one of ten light source
+%% parameters, again by symbolic name.  `Params'  is either a single value or a pointer
+%% to an array that contains the new values. 
+%%
+%%  To enable and disable lighting calculation, call  {@link gl:enable/1}  and  {@link gl:enable/1} 
+%%  with argument `?GL_LIGHTING'. Lighting is initially disabled. When it is enabled,
+%% light sources that are enabled contribute to the lighting calculation. Light source   i
+%% is enabled and disabled using  {@link gl:enable/1}  and  {@link gl:enable/1}  with argument `?GL_LIGHT'
+%%  i. 
+%%
+%%  The ten light parameters are as follows: 
+%%
+%% `?GL_AMBIENT':  `Params'  contains four integer or floating-point values that
+%% specify the ambient RGBA intensity of the light. Integer values are mapped linearly such
+%% that the most positive representable value maps to 1.0, and the most negative representable
+%% value maps to   -1.0. Floating-point values are mapped directly. Neither integer nor floating-point
+%% values are clamped. The initial ambient light intensity is (0, 0, 0, 1). 
+%%
+%% `?GL_DIFFUSE':  `Params'  contains four integer or floating-point values that
+%% specify the diffuse RGBA intensity of the light. Integer values are mapped linearly such
+%% that the most positive representable value maps to 1.0, and the most negative representable
+%% value maps to   -1.0. Floating-point values are mapped directly. Neither integer nor floating-point
+%% values are clamped. The initial value for `?GL_LIGHT0' is (1, 1, 1, 1); for other
+%% lights, the initial value is (0, 0, 0, 1). 
+%%
+%% `?GL_SPECULAR':  `Params'  contains four integer or floating-point values that
+%% specify the specular RGBA intensity of the light. Integer values are mapped linearly such
+%% that the most positive representable value maps to 1.0, and the most negative representable
+%% value maps to   -1.0. Floating-point values are mapped directly. Neither integer nor floating-point
+%% values are clamped. The initial value for `?GL_LIGHT0' is (1, 1, 1, 1); for other
+%% lights, the initial value is (0, 0, 0, 1). 
+%%
+%% `?GL_POSITION':  `Params'  contains four integer or floating-point values that
+%% specify the position of the light in homogeneous object coordinates. Both integer and
+%% floating-point values are mapped directly. Neither integer nor floating-point values are
+%% clamped. 
+%%
+%%  The position is transformed by the modelview matrix when ``gl:light'' is called (just
+%% as if it were a point), and it is stored in eye coordinates. If the   w component of the
+%% position is 0, the light is treated as a directional source. Diffuse and specular lighting
+%% calculations take the light's direction, but not its actual position, into account, and
+%% attenuation is disabled. Otherwise, diffuse and specular lighting calculations are based
+%% on the actual location of the light in eye coordinates, and attenuation is enabled. The
+%% initial position is (0, 0, 1, 0); thus, the initial light source is directional, parallel
+%% to, and in the direction of the  -z axis. 
+%%
+%% `?GL_SPOT_DIRECTION':  `Params'  contains three integer or floating-point values
+%% that specify the direction of the light in homogeneous object coordinates. Both integer
+%% and floating-point values are mapped directly. Neither integer nor floating-point values
+%% are clamped. 
+%%
+%%  The spot direction is transformed by the upper 3x3 of the modelview matrix when ``gl:light''
+%%  is called, and it is stored in eye coordinates. It is significant only when `?GL_SPOT_CUTOFF'
+%%  is not 180, which it is initially. The initial direction is  (0 0 -1). 
+%%
+%% `?GL_SPOT_EXPONENT':  `Params'  is a single integer or floating-point value that
+%% specifies the intensity distribution of the light. Integer and floating-point values are
+%% mapped directly. Only values in the range  [0 128] are accepted. 
+%%
+%%  Effective light intensity is attenuated by the cosine of the angle between the direction
+%% of the light and the direction from the light to the vertex being lighted, raised to the
+%% power of the spot exponent. Thus, higher spot exponents result in a more focused light
+%% source, regardless of the spot cutoff angle (see `?GL_SPOT_CUTOFF', next paragraph).
+%% The initial spot exponent is 0, resulting in uniform light distribution. 
+%%
+%% `?GL_SPOT_CUTOFF':  `Params'  is a single integer or floating-point value that
+%% specifies the maximum spread angle of a light source. Integer and floating-point values
+%% are mapped directly. Only values in the range  [0 90] and the special value 180 are accepted.
+%% If the angle between the direction of the light and the direction from the light to the
+%% vertex being lighted is greater than the spot cutoff angle, the light is completely masked.
+%% Otherwise, its intensity is controlled by the spot exponent and the attenuation factors.
+%% The initial spot cutoff is 180, resulting in uniform light distribution. 
+%%
+%% `?GL_CONSTANT_ATTENUATION'
+%%
+%% `?GL_LINEAR_ATTENUATION'
+%%
+%% `?GL_QUADRATIC_ATTENUATION':  `Params'  is a single integer or floating-point
+%% value that specifies one of the three light attenuation factors. Integer and floating-point
+%% values are mapped directly. Only nonnegative values are accepted. If the light is positional,
+%% rather than directional, its intensity is attenuated by the reciprocal of the sum of the
+%% constant factor, the linear factor times the distance between the light and the vertex
+%% being lighted, and the quadratic factor times the square of the same distance. The initial
+%% attenuation factors are (1, 0, 0), resulting in no attenuation.

+%% ``gl:lightModel'' sets the lighting model parameter.  `Pname'  names a parameter
+%% and  `Params'  gives the new value. There are three lighting model parameters: 
+%%
+%% `?GL_LIGHT_MODEL_AMBIENT':  `Params'  contains four integer or floating-point
+%% values that specify the ambient RGBA intensity of the entire scene. Integer values are
+%% mapped linearly such that the most positive representable value maps to 1.0, and the most
+%% negative representable value maps to   -1.0. Floating-point values are mapped directly.
+%% Neither integer nor floating-point values are clamped. The initial ambient scene intensity
+%% is (0.2, 0.2, 0.2, 1.0). 
+%%
+%% `?GL_LIGHT_MODEL_COLOR_CONTROL':  `Params'  must be either `?GL_SEPARATE_SPECULAR_COLOR'
+%%  or `?GL_SINGLE_COLOR'. `?GL_SINGLE_COLOR' specifies that a single color is
+%% generated from the lighting computation for a vertex. `?GL_SEPARATE_SPECULAR_COLOR'
+%% specifies that the specular color computation of lighting be stored separately from the
+%% remainder of the lighting computation. The specular color is summed into the generated
+%% fragment's color after the application of texture mapping (if enabled). The initial value
+%% is `?GL_SINGLE_COLOR'. 
+%%
+%% `?GL_LIGHT_MODEL_LOCAL_VIEWER':  `Params'  is a single integer or floating-point
+%% value that specifies how specular reflection angles are computed. If  `Params'  is
+%% 0 (or 0.0), specular reflection angles take the view direction to be parallel to and in
+%% the direction of the -`z' axis, regardless of the location of the vertex in eye coordinates.
+%% Otherwise, specular reflections are computed from the origin of the eye coordinate system.
+%% The initial value is 0. 
+%%
+%% `?GL_LIGHT_MODEL_TWO_SIDE':  `Params'  is a single integer or floating-point value
+%% that specifies whether one- or two-sided lighting calculations are done for polygons.
+%% It has no effect on the lighting calculations for points, lines, or bitmaps. If  `Params' 
+%%  is 0 (or 0.0), one-sided lighting is specified, and only the `front' material parameters
+%% are used in the lighting equation. Otherwise, two-sided lighting is specified. In this
+%% case, vertices of back-facing polygons are lighted using the `back' material parameters
+%% and have their normals reversed before the lighting equation is evaluated. Vertices of
+%% front-facing polygons are always lighted using the `front' material parameters, with
+%% no change to their normals. The initial value is 0. 
+%%
+%%  In RGBA mode, the lighted color of a vertex is the sum of the material emission intensity,
+%% the product of the material ambient reflectance and the lighting model full-scene ambient
+%% intensity, and the contribution of each enabled light source. Each light source contributes
+%% the sum of three terms: ambient, diffuse, and specular. The ambient light source contribution
+%% is the product of the material ambient reflectance and the light's ambient intensity.
+%% The diffuse light source contribution is the product of the material diffuse reflectance,
+%% the light's diffuse intensity, and the dot product of the vertex's normal with the normalized
+%% vector from the vertex to the light source. The specular light source contribution is
+%% the product of the material specular reflectance, the light's specular intensity, and
+%% the dot product of the normalized vertex-to-eye and vertex-to-light vectors, raised to
+%% the power of the shininess of the material. All three light source contributions are attenuated
+%% equally based on the distance from the vertex to the light source and on light source
+%% direction, spread exponent, and spread cutoff angle. All dot products are replaced with
+%% 0 if they evaluate to a negative value. 
+%%
+%%  The alpha component of the resulting lighted color is set to the alpha value of the material
+%% diffuse reflectance. 
+%%
+%%  In color index mode, the value of the lighted index of a vertex ranges from the ambient
+%% to the specular values passed to  {@link gl:materialf/3}  using `?GL_COLOR_INDEXES'.
+%% Diffuse and specular coefficients, computed with a (.30, .59, .11) weighting of the lights'
+%% colors, the shininess of the material, and the same reflection and attenuation equations
+%% as in the RGBA case, determine how much above ambient the resulting index is.

+%% @doc Specify material parameters for the lighting model
+%%
+%% ``gl:material'' assigns values to material parameters. There are two matched sets of
+%% material parameters. One, the `front-facing' set, is used to shade points, lines,
+%% bitmaps, and all polygons (when two-sided lighting is disabled), or just front-facing
+%% polygons (when two-sided lighting is enabled). The other set, `back-facing', is used
+%% to shade back-facing polygons only when two-sided lighting is enabled. Refer to the  {@link gl:lightModelf/2} 
+%%  reference page for details concerning one- and two-sided lighting calculations. 
+%%
+%% ``gl:material'' takes three arguments. The first,  `Face' , specifies whether the `?GL_FRONT'
+%%  materials, the `?GL_BACK' materials, or both `?GL_FRONT_AND_BACK' materials
+%% will be modified. The second,  `Pname' , specifies which of several parameters in one
+%% or both sets will be modified. The third,  `Params' , specifies what value or values
+%% will be assigned to the specified parameter. 
+%%
+%%  Material parameters are used in the lighting equation that is optionally applied to each
+%% vertex. The equation is discussed in the  {@link gl:lightModelf/2}  reference page. The parameters
+%% that can be specified using ``gl:material'', and their interpretations by the lighting
+%% equation, are as follows: 
+%%
+%% `?GL_AMBIENT':  `Params'  contains four integer or floating-point values that
+%% specify the ambient RGBA reflectance of the material. Integer values are mapped linearly
+%% such that the most positive representable value maps to 1.0, and the most negative representable
+%% value maps to   -1.0. Floating-point values are mapped directly. Neither integer nor floating-point
+%% values are clamped. The initial ambient reflectance for both front- and back-facing materials
+%% is (0.2, 0.2, 0.2, 1.0). 
+%%
+%% `?GL_DIFFUSE':  `Params'  contains four integer or floating-point values that
+%% specify the diffuse RGBA reflectance of the material. Integer values are mapped linearly
+%% such that the most positive representable value maps to 1.0, and the most negative representable
+%% value maps to   -1.0. Floating-point values are mapped directly. Neither integer nor floating-point
+%% values are clamped. The initial diffuse reflectance for both front- and back-facing materials
+%% is (0.8, 0.8, 0.8, 1.0). 
+%%
+%% `?GL_SPECULAR':  `Params'  contains four integer or floating-point values that
+%% specify the specular RGBA reflectance of the material. Integer values are mapped linearly
+%% such that the most positive representable value maps to 1.0, and the most negative representable
+%% value maps to   -1.0. Floating-point values are mapped directly. Neither integer nor floating-point
+%% values are clamped. The initial specular reflectance for both front- and back-facing materials
+%% is (0, 0, 0, 1). 
+%%
+%% `?GL_EMISSION':  `Params'  contains four integer or floating-point values that
+%% specify the RGBA emitted light intensity of the material. Integer values are mapped linearly
+%% such that the most positive representable value maps to 1.0, and the most negative representable
+%% value maps to   -1.0. Floating-point values are mapped directly. Neither integer nor floating-point
+%% values are clamped. The initial emission intensity for both front- and back-facing materials
+%% is (0, 0, 0, 1). 
+%%
+%% `?GL_SHININESS':  `Params'  is a single integer or floating-point value that specifies
+%% the RGBA specular exponent of the material. Integer and floating-point values are mapped
+%% directly. Only values in the range  [0 128] are accepted. The initial specular exponent for both
+%% front- and back-facing materials is 0. 
+%%
+%% `?GL_AMBIENT_AND_DIFFUSE':  Equivalent to calling ``gl:material'' twice with the
+%% same parameter values, once with `?GL_AMBIENT' and once with `?GL_DIFFUSE'. 
+%%
+%% `?GL_COLOR_INDEXES':  `Params'  contains three integer or floating-point values
+%% specifying the color indices for ambient, diffuse, and specular lighting. These three
+%% values, and `?GL_SHININESS', are the only material values used by the color index
+%% mode lighting equation. Refer to the  {@link gl:lightModelf/2}  reference page for a discussion
+%% of color index lighting.

+%%  `Pname'  is a symbolic constant indicating the parameter to be set, and  `Param'

+%%
+%% `?GL_PACK_SWAP_BYTES':  If true, byte ordering for multibyte color components, depth
+%% components, or stencil indices is reversed. That is, if a four-byte component consists
+%% of bytes  b 0,  b 1,  b 2,  b 3, it is stored in memory as  b 3,  b 2,  b 1,  b 0 if `?GL_PACK_SWAP_BYTES'
+%%  is true. `?GL_PACK_SWAP_BYTES' has no effect on the memory order of components within
+%% a pixel, only on the order of bytes within components or indices. For example, the three
+%% components of a `?GL_RGB' format pixel are always stored with red first, green second,
+%% and blue third, regardless of the value of `?GL_PACK_SWAP_BYTES'. 
+%%
+%% `?GL_PACK_LSB_FIRST':  If true, bits are ordered within a byte from least significant
+%% to most significant; otherwise, the first bit in each byte is the most significant one. 
+%%
+%% `?GL_PACK_ROW_LENGTH':  If greater than 0, `?GL_PACK_ROW_LENGTH' defines the
+%% number of pixels in a row. If the first pixel of a row is placed at location   p in memory,
+%% then the location of the first pixel of the next row is obtained by skipping

+%%  components or indices, where   n is the number of components or indices in a pixel,  l
+%% is the number of pixels in a row (`?GL_PACK_ROW_LENGTH' if it is greater than 0,
+%% the   width argument to the pixel routine otherwise),  a is the value of `?GL_PACK_ALIGNMENT'
+%% , and  s is the size, in bytes, of a single component (if   a&lt; s, then it is as if   a=
+%%  s). In the case of 1-bit values, the location of the next row is obtained by skipping 
+%%
+%%  k= 8  a |(n  l)/(8  a)|
+%%

+%% per pixel: first red, then green, and finally blue. 
+%%
+%% `?GL_PACK_IMAGE_HEIGHT':  If greater than 0, `?GL_PACK_IMAGE_HEIGHT' defines
+%% the number of pixels in an image three-dimensional texture volume, where ``image'' is
+%% defined by all pixels sharing the same third dimension index. If the first pixel of a

+%%  These values are provided as a convenience to the programmer; they provide no functionality
+%% that cannot be duplicated simply by incrementing the pointer passed to  {@link gl:readPixels/7} 
+%% . Setting `?GL_PACK_SKIP_PIXELS' to   i is equivalent to incrementing the pointer
+%% by   i  n components or indices, where   n is the number of components or indices in each
+%% pixel. Setting `?GL_PACK_SKIP_ROWS' to   j is equivalent to incrementing the pointer
+%% by   j  m components or indices, where   m is the number of components or indices per

+%% 
+%%
+%% `?GL_PACK_ALIGNMENT':  Specifies the alignment requirements for the start of each
+%% pixel row in memory. The allowable values are 1 (byte-alignment), 2 (rows aligned to even-numbered
+%% bytes), 4 (word-alignment), and 8 (rows start on double-word boundaries). 
+%%
+%%  The other six of the twelve storage parameters affect how pixel data is read from client

+%%
+%%  They are as follows:

+%% `?GL_UNPACK_SWAP_BYTES':  If true, byte ordering for multibyte color components,
+%% depth components, or stencil indices is reversed. That is, if a four-byte component consists
+%% of bytes  b 0,  b 1,  b 2,  b 3, it is taken from memory as  b 3,  b 2,  b 1,  b 0 if `?GL_UNPACK_SWAP_BYTES'

+%% ,  {@link gl:texSubImage1D/7} ,  {@link gl:texSubImage1D/7} , and  {@link gl:texSubImage1D/7} ).
+%% Pixel transfer operations happen in the same order, and in the same manner, regardless
+%% of the command that resulted in the pixel operation. Pixel storage modes (see  {@link gl:pixelStoref/2} 
+%% ) control the unpacking of pixels being read from client memory and the packing of pixels
+%% being written back into client memory. 
+%%
+%%  Pixel transfer operations handle four fundamental pixel types: `color', `color index'
+%% , `depth', and `stencil'. `Color' pixels consist of four floating-point
+%% values with unspecified mantissa and exponent sizes, scaled such that 0 represents zero
+%% intensity and 1 represents full intensity. `Color indices' comprise a single fixed-point
+%% value, with unspecified precision to the right of the binary point. `Depth' pixels
+%% comprise a single floating-point value, with unspecified mantissa and exponent sizes,
+%% scaled such that 0.0 represents the minimum depth buffer value, and 1.0 represents the
+%% maximum depth buffer value. Finally, `stencil' pixels comprise a single fixed-point
+%% value, with unspecified precision to the right of the binary point. 
+%%
+%%  The pixel transfer operations performed on the four basic pixel types are as follows: 
+%%
+%% `Color':  Each of the four color components is multiplied by a scale factor, then
+%% added to a bias factor. That is, the red component is multiplied by `?GL_RED_SCALE',
+%% then added to `?GL_RED_BIAS'; the green component is multiplied by `?GL_GREEN_SCALE'
+%% , then added to `?GL_GREEN_BIAS'; the blue component is multiplied by `?GL_BLUE_SCALE'
+%% , then added to `?GL_BLUE_BIAS'; and the alpha component is multiplied by `?GL_ALPHA_SCALE'
+%% , then added to `?GL_ALPHA_BIAS'. After all four color components are scaled and
+%% biased, each is clamped to the range  [0 1]. All color, scale, and bias values are specified
+%% with ``gl:pixelTransfer''. 
+%%
+%%  If `?GL_MAP_COLOR' is true, each color component is scaled by the size of the corresponding
+%% color-to-color map, then replaced by the contents of that map indexed by the scaled component.
+%% That is, the red component is scaled by `?GL_PIXEL_MAP_R_TO_R_SIZE', then replaced
+%% by the contents of `?GL_PIXEL_MAP_R_TO_R' indexed by itself. The green component
+%% is scaled by `?GL_PIXEL_MAP_G_TO_G_SIZE', then replaced by the contents of `?GL_PIXEL_MAP_G_TO_G'
+%%  indexed by itself. The blue component is scaled by `?GL_PIXEL_MAP_B_TO_B_SIZE',
+%% then replaced by the contents of `?GL_PIXEL_MAP_B_TO_B' indexed by itself. And the
+%% alpha component is scaled by `?GL_PIXEL_MAP_A_TO_A_SIZE', then replaced by the contents
+%% of `?GL_PIXEL_MAP_A_TO_A' indexed by itself. All components taken from the maps are
+%% then clamped to the range  [0 1]. `?GL_MAP_COLOR' is specified with ``gl:pixelTransfer''.
+%% The contents of the various maps are specified with  {@link gl:pixelMapfv/3} . 
+%%
+%%  If the ARB_imaging extension is supported, each of the four color components may be scaled
+%% and biased after transformation by the color matrix. That is, the red component is multiplied
+%% by `?GL_POST_COLOR_MATRIX_RED_SCALE', then added to `?GL_POST_COLOR_MATRIX_RED_BIAS'
+%% ; the green component is multiplied by `?GL_POST_COLOR_MATRIX_GREEN_SCALE', then
+%% added to `?GL_POST_COLOR_MATRIX_GREEN_BIAS'; the blue component is multiplied by `?GL_POST_COLOR_MATRIX_BLUE_SCALE'
+%% , then added to `?GL_POST_COLOR_MATRIX_BLUE_BIAS'; and the alpha component is multiplied
+%% by `?GL_POST_COLOR_MATRIX_ALPHA_SCALE', then added to `?GL_POST_COLOR_MATRIX_ALPHA_BIAS'
+%% . After all four color components are scaled and biased, each is clamped to the range  [0
+%% 1]. 
+%%
+%%  Similarly, if the ARB_imaging extension is supported, each of the four color components
+%% may be scaled and biased after processing by the enabled convolution filter. That is,
+%% the red component is multiplied by `?GL_POST_CONVOLUTION_RED_SCALE', then added to `?GL_POST_CONVOLUTION_RED_BIAS'
+%% ; the green component is multiplied by `?GL_POST_CONVOLUTION_GREEN_SCALE', then added
+%% to `?GL_POST_CONVOLUTION_GREEN_BIAS'; the blue component is multiplied by `?GL_POST_CONVOLUTION_BLUE_SCALE'
+%% , then added to `?GL_POST_CONVOLUTION_BLUE_BIAS'; and the alpha component is multiplied
+%% by `?GL_POST_CONVOLUTION_ALPHA_SCALE', then added to `?GL_POST_CONVOLUTION_ALPHA_BIAS'
+%% . After all four color components are scaled and biased, each is clamped to the range  [0
+%% 1]. 
+%%
+%% `Color index':  Each color index is shifted left by `?GL_INDEX_SHIFT' bits;
+%% any bits beyond the number of fraction bits carried by the fixed-point index are filled
+%% with zeros. If `?GL_INDEX_SHIFT' is negative, the shift is to the right, again zero
+%% filled. Then `?GL_INDEX_OFFSET' is added to the index. `?GL_INDEX_SHIFT' and `?GL_INDEX_OFFSET'
+%%  are specified with ``gl:pixelTransfer''. 
+%%
+%%  From this point, operation diverges depending on the required format of the resulting
+%% pixels. If the resulting pixels are to be written to a color index buffer, or if they
+%% are being read back to client memory in `?GL_COLOR_INDEX' format, the pixels continue
+%% to be treated as indices. If `?GL_MAP_COLOR' is true, each index is masked by   2 n-1
+%% , where   n is `?GL_PIXEL_MAP_I_TO_I_SIZE', then replaced by the contents of `?GL_PIXEL_MAP_I_TO_I'
+%%  indexed by the masked value. `?GL_MAP_COLOR' is specified with ``gl:pixelTransfer''
+%% . The contents of the index map is specified with  {@link gl:pixelMapfv/3} . 
+%%
+%%  If the resulting pixels are to be written to an RGBA color buffer, or if they are read
+%% back to client memory in a format other than `?GL_COLOR_INDEX', the pixels are converted
+%% from indices to colors by referencing the four maps `?GL_PIXEL_MAP_I_TO_R', `?GL_PIXEL_MAP_I_TO_G'
+%% , `?GL_PIXEL_MAP_I_TO_B', and `?GL_PIXEL_MAP_I_TO_A'. Before being dereferenced,
+%% the index is masked by   2 n-1, where   n is `?GL_PIXEL_MAP_I_TO_R_SIZE' for the
+%% red map, `?GL_PIXEL_MAP_I_TO_G_SIZE' for the green map, `?GL_PIXEL_MAP_I_TO_B_SIZE'
+%%  for the blue map, and `?GL_PIXEL_MAP_I_TO_A_SIZE' for the alpha map. All components
+%% taken from the maps are then clamped to the range  [0 1]. The contents of the four maps is
+%% specified with  {@link gl:pixelMapfv/3} . 
+%%
+%% `Depth':  Each depth value is multiplied by `?GL_DEPTH_SCALE', added to `?GL_DEPTH_BIAS'
+%% , then clamped to the range  [0 1]. 
+%%
+%% `Stencil':  Each index is shifted `?GL_INDEX_SHIFT' bits just as a color index
+%% is, then added to `?GL_INDEX_OFFSET'. If `?GL_MAP_STENCIL' is true, each index
+%% is masked by   2 n-1, where   n is `?GL_PIXEL_MAP_S_TO_S_SIZE', then replaced by
+%% the contents of `?GL_PIXEL_MAP_S_TO_S' indexed by the masked value.

+%% . Use of these maps is described completely in the  {@link gl:pixelTransferf/2}  reference
+%% page, and partly in the reference pages for the pixel and texture image commands. Only
+%% the specification of the maps is described in this reference page. 
+%%
+%%  `Map'  is a symbolic map name, indicating one of ten maps to set.  `Mapsize'  specifies
+%% the number of entries in the map, and  `Values'  is a pointer to an array of  `Mapsize' 
+%%  map values. 
+%%
+%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_UNPACK_BUFFER' target
+%%  (see  {@link gl:bindBuffer/2} ) while a pixel transfer map is specified,  `Values'  is
+%% treated as a byte offset into the buffer object's data store. 
+%%
+%%  The ten maps are as follows: 
+%%
+%% `?GL_PIXEL_MAP_I_TO_I':  Maps color indices to color indices. 
+%%
+%% `?GL_PIXEL_MAP_S_TO_S':  Maps stencil indices to stencil indices. 
+%%
+%% `?GL_PIXEL_MAP_I_TO_R':  Maps color indices to red components. 
+%%
+%% `?GL_PIXEL_MAP_I_TO_G':  Maps color indices to green components. 
+%%
+%% `?GL_PIXEL_MAP_I_TO_B':  Maps color indices to blue components. 
+%%
+%% `?GL_PIXEL_MAP_I_TO_A':  Maps color indices to alpha components. 
+%%
+%% `?GL_PIXEL_MAP_R_TO_R':  Maps red components to red components. 
+%%
+%% `?GL_PIXEL_MAP_G_TO_G':  Maps green components to green components. 
+%%
+%% `?GL_PIXEL_MAP_B_TO_B':  Maps blue components to blue components. 
+%%
+%% `?GL_PIXEL_MAP_A_TO_A':  Maps alpha components to alpha components. 
+%%
+%%  The entries in a map can be specified as single-precision floating-point numbers, unsigned
+%% short integers, or unsigned int integers. Maps that store color component values (all
+%% but `?GL_PIXEL_MAP_I_TO_I' and `?GL_PIXEL_MAP_S_TO_S') retain their values in
+%% floating-point format, with unspecified mantissa and exponent sizes. Floating-point values
+%% specified by ``gl:pixelMapfv'' are converted directly to the internal floating-point
+%% format of these maps, then clamped to the range [0,1]. Unsigned integer values specified
+%% by ``gl:pixelMapusv'' and ``gl:pixelMapuiv'' are converted linearly such that the
+%% largest representable integer maps to 1.0, and 0 maps to 0.0. 
+%%
+%%  Maps that store indices, `?GL_PIXEL_MAP_I_TO_I' and `?GL_PIXEL_MAP_S_TO_S',
+%% retain their values in fixed-point format, with an unspecified number of bits to the right
+%% of the binary point. Floating-point values specified by ``gl:pixelMapfv'' are converted
+%% directly to the internal fixed-point format of these maps. Unsigned integer values specified
+%% by ``gl:pixelMapusv'' and ``gl:pixelMapuiv'' specify integer values, with all 0's
+%% to the right of the binary point. 
+%%
+%%  The following table shows the initial sizes and values for each of the maps. Maps that
+%% are indexed by either color or stencil indices must have  `Mapsize'  =   2 n for some
+%%   n or the results are undefined. The maximum allowable size for each map depends on the

+%% @doc Draw a bitmap
+%%
+%%  A bitmap is a binary image. When drawn, the bitmap is positioned relative to the current
+%% raster position, and frame buffer pixels corresponding to 1's in the bitmap are written
+%% using the current raster color or index. Frame buffer pixels corresponding to 0's in the
+%% bitmap are not modified. 
+%%
+%% ``gl:bitmap'' takes seven arguments. The first pair specifies the width and height of
+%% the bitmap image. The second pair specifies the location of the bitmap origin relative
+%% to the lower left corner of the bitmap image. The third pair of arguments specifies `x'
+%%  and `y' offsets to be added to the current raster position after the bitmap has
+%% been drawn. The final argument is a pointer to the bitmap image itself. 
+%%
+%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_UNPACK_BUFFER' target
+%%  (see  {@link gl:bindBuffer/2} ) while a bitmap image is specified,  `Bitmap'  is treated
+%% as a byte offset into the buffer object's data store. 
+%%
+%%  The bitmap image is interpreted like image data for the  {@link gl:drawPixels/5}  command,
+%% with  `Width'  and  `Height'  corresponding to the width and height arguments of
+%% that command, and with `type' set to `?GL_BITMAP' and `format' set to `?GL_COLOR_INDEX'
+%% . Modes specified using  {@link gl:pixelStoref/2}  affect the interpretation of bitmap image
+%% data; modes specified using  {@link gl:pixelTransferf/2}  do not. 
+%%
+%%  If the current raster position is invalid, ``gl:bitmap'' is ignored. Otherwise, the
+%% lower left corner of the bitmap image is positioned at the window coordinates 
+%%
+%%  x w=|x r-x o|
+%%
+%%  y w=|y r-y o|
+%%
+%%  where  (x r y r) is the raster position and  (x o y o) is the bitmap origin. Fragments are then generated
+%% for each pixel corresponding to a 1 (one) in the bitmap image. These fragments are generated
+%% using the current raster `z' coordinate, color or color index, and current raster
+%% texture coordinates. They are then treated just as if they had been generated by a point,
+%% line, or polygon, including texture mapping, fogging, and all per-fragment operations
+%% such as alpha and depth testing. 
+%%
+%%  After the bitmap has been drawn, the `x' and `y' coordinates of the current
+%% raster position are offset by  `Xmove'  and  `Ymove' . No change is made to the `z'
+%%  coordinate of the current raster position, or to the current raster color, texture coordinates,

+%% @doc Read a block of pixels from the frame buffer
+%%
+%% ``gl:readPixels'' returns pixel data from the frame buffer, starting with the pixel
+%% whose lower left corner is at location ( `X' ,  `Y' ), into client memory starting
+%% at location  `Data' . Several parameters control the processing of the pixel data before
+%% it is placed into client memory. These parameters are set with  {@link gl:pixelStoref/2} .
+%% This reference page describes the effects on ``gl:readPixels'' of most, but not all
+%% of the parameters specified by these three commands. 
+%%
+%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_PACK_BUFFER' target
+%%  (see  {@link gl:bindBuffer/2} ) while a block of pixels is requested,  `Data'  is treated
+%% as a byte offset into the buffer object's data store rather than a pointer to client memory.
+%% 
+%%
+%% ``gl:readPixels'' returns values from each pixel with lower left corner at (x+i y+j) for   0&lt;=
+%%  i&lt; width and  0&lt;= j&lt; height. This pixel is said to be the   ith pixel in the  
+%% jth row. Pixels are returned in row order from the lowest to the highest row, left to
+%% right in each row. 
+%%
+%%  `Format'  specifies the format for the returned pixel values; accepted values are: 
+%%
+%% `?GL_STENCIL_INDEX':  Stencil values are read from the stencil buffer. Each index
+%% is converted to fixed point, shifted left or right depending on the value and sign of `?GL_INDEX_SHIFT'
+%% , and added to `?GL_INDEX_OFFSET'. If `?GL_MAP_STENCIL' is `?GL_TRUE',
+%% indices are replaced by their mappings in the table `?GL_PIXEL_MAP_S_TO_S'. 
+%%
+%% `?GL_DEPTH_COMPONENT':  Depth values are read from the depth buffer. Each component
+%% is converted to floating point such that the minimum depth value maps to 0 and the maximum
+%% value maps to 1. Each component is then multiplied by `?GL_DEPTH_SCALE', added to `?GL_DEPTH_BIAS'
+%% , and finally clamped to the range  [0 1]. 
+%%
+%% `?GL_DEPTH_STENCIL':  Values are taken from both the depth and stencil buffers. The  `Type' 
+%%  parameter must be `?GL_UNSIGNED_INT_24_8' or `?GL_FLOAT_32_UNSIGNED_INT_24_8_REV'

+%% components are treated as groups of one, two, three, or four values, again based on  `Format' 
+%% . Both individual indices and groups of components are referred to as pixels. If  `Type' 
+%%  is `?GL_BITMAP', the data must be unsigned bytes, and  `Format'  must be either `?GL_COLOR_INDEX'
+%%  or `?GL_STENCIL_INDEX'. Each unsigned byte is treated as eight 1-bit pixels, with
+%% bit ordering determined by `?GL_UNPACK_LSB_FIRST' (see  {@link gl:pixelStoref/2} ). 
+%%
+%%  width*height pixels are read from memory, starting at location  `Data' . By default,
+%% these pixels are taken from adjacent memory locations, except that after all  `Width' 
+%% pixels are read, the read pointer is advanced to the next four-byte boundary. The four-byte
+%% row alignment is specified by  {@link gl:pixelStoref/2}  with argument `?GL_UNPACK_ALIGNMENT'
+%% , and it can be set to one, two, four, or eight bytes. Other pixel store parameters specify
+%% different read pointer advancements, both before the first pixel is read and after all  `Width' 
+%%  pixels are read. See the  {@link gl:pixelStoref/2}  reference page for details on these options.
+%% 
+%%
+%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_UNPACK_BUFFER' target
+%%  (see  {@link gl:bindBuffer/2} ) while a block of pixels is specified,  `Data'  is treated
+%% as a byte offset into the buffer object's data store. 
+%%
+%%  The   width*height pixels that are read from memory are each operated on in the same
+%% way, based on the values of several parameters specified by  {@link gl:pixelTransferf/2} 
+%% and  {@link gl:pixelMapfv/3} . The details of these operations, as well as the target buffer
+%% into which the pixels are drawn, are specific to the format of the pixels, as specified
+%% by  `Format' .  `Format'  can assume one of 13 symbolic values: 
+%%
+%% `?GL_COLOR_INDEX':  Each pixel is a single value, a color index. It is converted
+%% to fixed-point format, with an unspecified number of bits to the right of the binary point,
+%% regardless of the memory data type. Floating-point values convert to true fixed-point
+%% values. Signed and unsigned integer data is converted with all fraction bits set to 0.
+%% Bitmap data convert to either 0 or 1. 
+%%
+%%  Each fixed-point index is then shifted left by `?GL_INDEX_SHIFT' bits and added to `?GL_INDEX_OFFSET'
+%% . If `?GL_INDEX_SHIFT' is negative, the shift is to the right. In either case, zero
+%% bits fill otherwise unspecified bit locations in the result. 
+%%
+%%  If the GL is in RGBA mode, the resulting index is converted to an RGBA pixel with the
+%% help of the `?GL_PIXEL_MAP_I_TO_R', `?GL_PIXEL_MAP_I_TO_G', `?GL_PIXEL_MAP_I_TO_B'
+%% , and `?GL_PIXEL_MAP_I_TO_A' tables. If the GL is in color index mode, and if `?GL_MAP_COLOR'
+%%  is true, the index is replaced with the value that it references in lookup table `?GL_PIXEL_MAP_I_TO_I'
+%% . Whether the lookup replacement of the index is done or not, the integer part of the
+%% index is then ANDed with   2 b-1, where   b is the number of bits in a color index buffer.
+%% 
+%%
+%%  The GL then converts the resulting indices or RGBA colors to fragments by attaching the
+%% current raster position `z' coordinate and texture coordinates to each pixel, then
+%% assigning   x and   y window coordinates to the   nth fragment such that  x n= x r+n%
+%% width
+%%
+%%  y n= y r+|n/width|
+%%
+%%  where  (x r y r) is the current raster position. These pixel fragments are then treated just like
+%% the fragments generated by rasterizing points, lines, or polygons. Texture mapping, fog,
+%% and all the fragment operations are applied before the fragments are written to the frame
+%% buffer. 
+%%
+%% `?GL_STENCIL_INDEX':  Each pixel is a single value, a stencil index. It is converted
+%% to fixed-point format, with an unspecified number of bits to the right of the binary point,
+%% regardless of the memory data type. Floating-point values convert to true fixed-point
+%% values. Signed and unsigned integer data is converted with all fraction bits set to 0.
+%% Bitmap data convert to either 0 or 1. 
+%%
+%%  Each fixed-point index is then shifted left by `?GL_INDEX_SHIFT' bits, and added
+%% to `?GL_INDEX_OFFSET'. If `?GL_INDEX_SHIFT' is negative, the shift is to the
+%% right. In either case, zero bits fill otherwise unspecified bit locations in the result.
+%% If `?GL_MAP_STENCIL' is true, the index is replaced with the value that it references
+%% in lookup table `?GL_PIXEL_MAP_S_TO_S'. Whether the lookup replacement of the index
+%% is done or not, the integer part of the index is then ANDed with   2 b-1, where   b is
+%% the number of bits in the stencil buffer. The resulting stencil indices are then written
+%% to the stencil buffer such that the   nth index is written to location 
+%%
+%%  x n= x r+n% width
+%%
+%%  y n= y r+|n/width|
+%%
+%%  where  (x r y r) is the current raster position. Only the pixel ownership test, the scissor test,
+%% and the stencil writemask affect these write operations. 
+%%
+%% `?GL_DEPTH_COMPONENT':  Each pixel is a single-depth component. Floating-point data
+%% is converted directly to an internal floating-point format with unspecified precision.
+%% Signed integer data is mapped linearly to the internal floating-point format such that
+%% the most positive representable integer value maps to 1.0, and the most negative representable
+%% value maps to   -1.0. Unsigned integer data is mapped similarly: the largest integer value
+%% maps to 1.0, and 0 maps to 0.0. The resulting floating-point depth value is then multiplied
+%% by `?GL_DEPTH_SCALE' and added to `?GL_DEPTH_BIAS'. The result is clamped to
+%% the range  [0 1]. 
+%%
+%%  The GL then converts the resulting depth components to fragments by attaching the current
+%% raster position color or color index and texture coordinates to each pixel, then assigning
+%%   x and   y window coordinates to the   nth fragment such that 
+%%
+%%  x n= x r+n% width
+%%
+%%  y n= y r+|n/width|
+%%
+%%  where  (x r y r) is the current raster position. These pixel fragments are then treated just like
+%% the fragments generated by rasterizing points, lines, or polygons. Texture mapping, fog,
+%% and all the fragment operations are applied before the fragments are written to the frame
+%% buffer. 
+%%
+%% `?GL_RGBA'
+%%
+%% `?GL_BGRA':  Each pixel is a four-component group: For `?GL_RGBA', the red component
+%% is first, followed by green, followed by blue, followed by alpha; for `?GL_BGRA'
+%% the order is blue, green, red and then alpha. Floating-point values are converted directly
+%% to an internal floating-point format with unspecified precision. Signed integer values
+%% are mapped linearly to the internal floating-point format such that the most positive
+%% representable integer value maps to 1.0, and the most negative representable value maps
+%% to   -1.0. (Note that this mapping does not convert 0 precisely to 0.0.) Unsigned integer
+%% data is mapped similarly: The largest integer value maps to 1.0, and 0 maps to 0.0. The
+%% resulting floating-point color values are then multiplied by `?GL_c_SCALE' and added
+%% to `?GL_c_BIAS', where `c' is RED, GREEN, BLUE, and ALPHA for the respective
+%% color components. The results are clamped to the range  [0 1]. 
+%%
+%%  If `?GL_MAP_COLOR' is true, each color component is scaled by the size of lookup
+%% table `?GL_PIXEL_MAP_c_TO_c', then replaced by the value that it references in that
+%% table. `c' is R, G, B, or A respectively. 
+%%
+%%  The GL then converts the resulting RGBA colors to fragments by attaching the current
+%% raster position `z' coordinate and texture coordinates to each pixel, then assigning
+%%   x and   y window coordinates to the   nth fragment such that 
+%%
+%%  x n= x r+n% width
+%%
+%%  y n= y r+|n/width|
+%%
+%%  where  (x r y r) is the current raster position. These pixel fragments are then treated just like
+%% the fragments generated by rasterizing points, lines, or polygons. Texture mapping, fog,
+%% and all the fragment operations are applied before the fragments are written to the frame
+%% buffer. 
+%%
+%% `?GL_RED':  Each pixel is a single red component. This component is converted to
+%% the internal floating-point format in the same way the red component of an RGBA pixel
+%% is. It is then converted to an RGBA pixel with green and blue set to 0, and alpha set
+%% to 1. After this conversion, the pixel is treated as if it had been read as an RGBA pixel.
+%% 
+%%
+%% `?GL_GREEN':  Each pixel is a single green component. This component is converted
+%% to the internal floating-point format in the same way the green component of an RGBA pixel
+%% is. It is then converted to an RGBA pixel with red and blue set to 0, and alpha set to
+%% 1. After this conversion, the pixel is treated as if it had been read as an RGBA pixel. 
+%%
+%% `?GL_BLUE':  Each pixel is a single blue component. This component is converted to
+%% the internal floating-point format in the same way the blue component of an RGBA pixel
+%% is. It is then converted to an RGBA pixel with red and green set to 0, and alpha set to
+%% 1. After this conversion, the pixel is treated as if it had been read as an RGBA pixel. 
+%%
+%% `?GL_ALPHA':  Each pixel is a single alpha component. This component is converted
+%% to the internal floating-point format in the same way the alpha component of an RGBA pixel
+%% is. It is then converted to an RGBA pixel with red, green, and blue set to 0. After this
+%% conversion, the pixel is treated as if it had been read as an RGBA pixel. 
+%%
+%% `?GL_RGB'
+%%
+%% `?GL_BGR':  Each pixel is a three-component group: red first, followed by green,
+%% followed by blue; for `?GL_BGR', the first component is blue, followed by green and
+%% then red. Each component is converted to the internal floating-point format in the same
+%% way the red, green, and blue components of an RGBA pixel are. The color triple is converted
+%% to an RGBA pixel with alpha set to 1. After this conversion, the pixel is treated as if
+%% it had been read as an RGBA pixel.

+%% @doc Copy pixels in the frame buffer
+%%
+%% ``gl:copyPixels'' copies a screen-aligned rectangle of pixels from the specified frame
+%% buffer location to a region relative to the current raster position. Its operation is
+%% well defined only if the entire pixel source region is within the exposed portion of the
+%% window. Results of copies from outside the window, or from regions of the window that
+%% are not exposed, are hardware dependent and undefined. 
+%%
+%%  `X'  and  `Y'  specify the window coordinates of the lower left corner of the rectangular
+%% region to be copied.  `Width'  and  `Height'  specify the dimensions of the rectangular
+%% region to be copied. Both  `Width'  and  `Height'  must not be negative. 
+%%
+%%  Several parameters control the processing of the pixel data while it is being copied.
+%% These parameters are set with three commands:  {@link gl:pixelTransferf/2} ,  {@link gl:pixelMapfv/3} 
+%% , and  {@link gl:pixelZoom/2} . This reference page describes the effects on ``gl:copyPixels''
+%%  of most, but not all, of the parameters specified by these three commands. 
+%%
+%% ``gl:copyPixels'' copies values from each pixel with the lower left-hand corner at (x+i
+%% y+j)
+%% for   0&lt;= i&lt; width and   0&lt;= j&lt; height. This pixel is said to be the   ith
+%% pixel in the   jth row. Pixels are copied in row order from the lowest to the highest
+%% row, left to right in each row. 
+%%
+%%  `Type'  specifies whether color, depth, or stencil data is to be copied. The details
+%% of the transfer for each data type are as follows: 
+%%
+%% `?GL_COLOR':  Indices or RGBA colors are read from the buffer currently specified
+%% as the read source buffer (see  {@link gl:readBuffer/1} ). If the GL is in color index mode,
+%% each index that is read from this buffer is converted to a fixed-point format with an
+%% unspecified number of bits to the right of the binary point. Each index is then shifted
+%% left by `?GL_INDEX_SHIFT' bits, and added to `?GL_INDEX_OFFSET'. If `?GL_INDEX_SHIFT'
+%%  is negative, the shift is to the right. In either case, zero bits fill otherwise unspecified
+%% bit locations in the result. If `?GL_MAP_COLOR' is true, the index is replaced with
+%% the value that it references in lookup table `?GL_PIXEL_MAP_I_TO_I'. Whether the
+%% lookup replacement of the index is done or not, the integer part of the index is then
+%% ANDed with   2 b-1, where   b is the number of bits in a color index buffer. 
+%%
+%%  If the GL is in RGBA mode, the red, green, blue, and alpha components of each pixel that
+%% is read are converted to an internal floating-point format with unspecified precision.
+%% The conversion maps the largest representable component value to 1.0, and component value
+%% 0 to 0.0. The resulting floating-point color values are then multiplied by `?GL_c_SCALE'
+%%  and added to `?GL_c_BIAS', where `c' is RED, GREEN, BLUE, and ALPHA for the
+%% respective color components. The results are clamped to the range [0,1]. If `?GL_MAP_COLOR'
+%%  is true, each color component is scaled by the size of lookup table `?GL_PIXEL_MAP_c_TO_c'
+%% , then replaced by the value that it references in that table. `c' is R, G, B, or
+%% A. 
+%%
+%%  If the ARB_imaging extension is supported, the color values may be additionally processed
+%% by color-table lookups, color-matrix transformations, and convolution filters. 
+%%
+%%  The GL then converts the resulting indices or RGBA colors to fragments by attaching the
+%% current raster position `z' coordinate and texture coordinates to each pixel, then
+%% assigning window coordinates (x r+i y r+j), where  (x r y r) is the current raster position, and the pixel was
+%% the   ith pixel in the   jth row. These pixel fragments are then treated just like the
+%% fragments generated by rasterizing points, lines, or polygons. Texture mapping, fog, and
+%% all the fragment operations are applied before the fragments are written to the frame
+%% buffer. 
+%%
+%% `?GL_DEPTH':  Depth values are read from the depth buffer and converted directly
+%% to an internal floating-point format with unspecified precision. The resulting floating-point
+%% depth value is then multiplied by `?GL_DEPTH_SCALE' and added to `?GL_DEPTH_BIAS'
+%% . The result is clamped to the range [0,1]. 
+%%
+%%  The GL then converts the resulting depth components to fragments by attaching the current
+%% raster position color or color index and texture coordinates to each pixel, then assigning
+%% window coordinates (x r+i y r+j), where  (x r y r) is the current raster position, and the pixel was the   ith
+%% pixel in the   jth row. These pixel fragments are then treated just like the fragments
+%% generated by rasterizing points, lines, or polygons. Texture mapping, fog, and all the
+%% fragment operations are applied before the fragments are written to the frame buffer. 
+%%
+%% `?GL_STENCIL':  Stencil indices are read from the stencil buffer and converted to
+%% an internal fixed-point format with an unspecified number of bits to the right of the
+%% binary point. Each fixed-point index is then shifted left by `?GL_INDEX_SHIFT' bits,
+%% and added to `?GL_INDEX_OFFSET'. If `?GL_INDEX_SHIFT' is negative, the shift
+%% is to the right. In either case, zero bits fill otherwise unspecified bit locations in
+%% the result. If `?GL_MAP_STENCIL' is true, the index is replaced with the value that
+%% it references in lookup table `?GL_PIXEL_MAP_S_TO_S'. Whether the lookup replacement
+%% of the index is done or not, the integer part of the index is then ANDed with   2 b-1,
+%% where   b is the number of bits in the stencil buffer. The resulting stencil indices are
+%% then written to the stencil buffer such that the index read from the   ith location of
+%% the   jth row is written to location (x r+i y r+j), where  (x r y r) is the current raster position. Only the
+%% pixel ownership test, the scissor test, and the stencil writemask affect these write operations.
+%% 
+%%
+%%  The rasterization described thus far assumes pixel zoom factors of 1.0. If  {@link gl:pixelZoom/2} 
+%%  is used to change the   x and   y pixel zoom factors, pixels are converted to fragments
+%% as follows. If  (x r y r) is the current raster position, and a given pixel is in the   ith location
+%% in the   jth row of the source pixel rectangle, then fragments are generated for pixels
+%% whose centers are in the rectangle with corners at 
+%%
+%% (x r+(zoom x)  i y r+(zoom y)  j)
+%%
+%%  and 
+%%
+%% (x r+(zoom x)(i+1) y r+(zoom y)(j+1))

+%% ``gl:texGen'' selects a texture-coordinate generation function or supplies coefficients

+%% ) texture coordinates; it must be one of the symbols `?GL_S', `?GL_T', `?GL_R'
+%% , or `?GL_Q'.  `Pname'  must be one of three symbolic constants: `?GL_TEXTURE_GEN_MODE'
+%% , `?GL_OBJECT_PLANE', or `?GL_EYE_PLANE'. If  `Pname'  is `?GL_TEXTURE_GEN_MODE'
+%% , then  `Params'  chooses a mode, one of `?GL_OBJECT_LINEAR', `?GL_EYE_LINEAR'
+%% , `?GL_SPHERE_MAP', `?GL_NORMAL_MAP', or `?GL_REFLECTION_MAP'. If  `Pname' 
+%%  is either `?GL_OBJECT_PLANE' or `?GL_EYE_PLANE',  `Params'  contains coefficients
+%% for the corresponding texture generation function. 
+%%
+%%  If the texture generation function is `?GL_OBJECT_LINEAR', the function 
+%%
+%%  g= p 1*x o+p 2*y o+p 3*z o+p 4*w o
+%%
+%%  is used, where   g is the value computed for the coordinate named in  `Coord' ,  p 1,
+%%  p 2,  p 3, and  p 4 are the four values supplied in  `Params' , and  x o,  y o,  z o,
+%% and  w o are the object coordinates of the vertex. This function can be used, for example,
+%% to texture-map terrain using sea level as a reference plane (defined by   p 1,   p 2,   p
+%% 3, and   p 4). The altitude of a terrain vertex is computed by the `?GL_OBJECT_LINEAR'
+%%  coordinate generation function as its distance from sea level; that altitude can then
+%% be used to index the texture image to map white snow onto peaks and green grass onto foothills.
+%% 
+%%
+%%  If the texture generation function is `?GL_EYE_LINEAR', the function 
+%%
+%%  g=(p 1)"*x e+(p 2)"*y e+(p 3)"*z e+(p 4)"*w e

+%%  is used, where

+%% and  p 4 are the values supplied in  `Params' , and  M is the modelview matrix when ``gl:texGen''
+%%  is invoked. If   M is poorly conditioned or singular, texture coordinates generated by
+%% the resulting function may be inaccurate or undefined. 
+%%
+%%  Note that the values in  `Params'  define a reference plane in eye coordinates. The
+%% modelview matrix that is applied to them may not be the same one in effect when the polygon
+%% vertices are transformed. This function establishes a field of texture coordinates that
+%% can produce dynamic contour lines on moving objects. 
+%%
+%%  If the texture generation function is `?GL_SPHERE_MAP' and  `Coord'  is either `?GL_S'
+%%  or `?GL_T',  s and   t texture coordinates are generated as follows. Let `u'
+%% be the unit vector pointing from the origin to the polygon vertex (in eye coordinates).
+%% Let `n' sup prime be the current normal, after transformation to eye coordinates.
+%% Let 
+%%
+%%  f=(f x  f y  f z) T be the reflection vector such that 
+%%
+%%  f= u-2  n" (n") T  u
+%%
+%%  Finally, let   m= 2 ((f x) 2+(f y) 2+(f z+1) 2). Then the values assigned to the   s and   t texture coordinates
+%% are 
+%%
+%%  s= f x/m+1/2
+%%
+%%  t= f y/m+1/2
+%%
+%%  To enable or disable a texture-coordinate generation function, call  {@link gl:enable/1} 
+%% or  {@link gl:enable/1}  with one of the symbolic texture-coordinate names (`?GL_TEXTURE_GEN_S'

+%%
+%% ``gl:texParameter'' assigns the value or values in  `Params'  to the texture parameter
+%% specified as  `Pname' .  `Target'  defines the target texture, either `?GL_TEXTURE_1D'
+%% , `?GL_TEXTURE_2D', `?GL_TEXTURE_1D_ARRAY', `?GL_TEXTURE_2D_ARRAY', `?GL_TEXTURE_RECTANGLE'
+%% , or `?GL_TEXTURE_3D'. The following symbols are accepted in  `Pname' : 
+%%
+%% `?GL_TEXTURE_BASE_LEVEL':  Specifies the index of the lowest defined mipmap level.
+%% This is an integer value. The initial value is 0. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_BORDER_COLOR':  The data in  `Params'  specifies four values that
+%% define the border values that should be used for border texels. If a texel is sampled
+%% from the border of the texture, the values of `?GL_TEXTURE_BORDER_COLOR' are interpreted
+%% as an RGBA color to match the texture's internal format and substituted for the non-existent
+%% texel data. If the texture contains depth components, the first component of `?GL_TEXTURE_BORDER_COLOR'
+%%  is interpreted as a depth value. The initial value is ( 0.0, 0.0, 0.0, 0.0 ). 
+%%
+%%  If the values for `?GL_TEXTURE_BORDER_COLOR' are specified with ``gl:texParameterIiv''
+%%  or ``gl:texParameterIuiv'', the values are stored unmodified with an internal data
+%% type of integer. If specified with ``gl:texParameteriv'', they are converted to floating
+%% point with the following equation:  f= 2 c+1 2 b-/1. If specified with ``gl:texParameterfv''
+%% , they are stored unmodified as floating-point values. 
+%%
+%% `?GL_TEXTURE_COMPARE_FUNC':  Specifies the comparison operator used when `?GL_TEXTURE_COMPARE_MODE'
+%%  is set to `?GL_COMPARE_REF_TO_TEXTURE'. Permissible values are: <table><tbody><tr><td>

+%% interpolated texture coordinate, and   D t is the depth texture value sampled from the
+%% currently bound depth texture.  result is assigned to the the red channel. 
+%%
+%% `?GL_TEXTURE_COMPARE_MODE':  Specifies the texture comparison mode for currently
+%% bound depth textures. That is, a texture whose internal format is `?GL_DEPTH_COMPONENT_*'
+%% ; see  {@link gl:texImage2D/9} ) Permissible values are: 
+%%
+%% `?GL_COMPARE_REF_TO_TEXTURE':  Specifies that the interpolated and clamped   r texture
+%% coordinate should be compared to the value in the currently bound depth texture. See the
+%% discussion of `?GL_TEXTURE_COMPARE_FUNC' for details of how the comparison is evaluated.
+%% The result of the comparison is assigned to the red channel. 
+%%
+%% `?GL_NONE':  Specifies that the red channel should be assigned the appropriate value
+%% from the currently bound depth texture. 
+%%
+%% `?GL_TEXTURE_LOD_BIAS':  `Params'  specifies a fixed bias value that is to be
+%% added to the level-of-detail parameter for the texture before texture sampling. The specified
+%% value is added to the shader-supplied bias value (if any) and subsequently clamped into
+%% the implementation-defined range [( -  bias max)(bias max)], where  bias max is the value of the implementation
+%% defined constant `?GL_MAX_TEXTURE_LOD_BIAS'. The initial value is 0.0. 
+%%
+%% `?GL_TEXTURE_MIN_FILTER':  The texture minifying function is used whenever the level-of-detail
+%% function used when sampling from the texture determines that the texture should be minified.
+%% There are six defined minifying functions. Two of them use either the nearest texture
+%% elements or a weighted average of multiple texture elements to compute the texture value.
+%% The other four use mipmaps. 
+%%
+%%  A mipmap is an ordered set of arrays representing the same image at progressively lower
+%% resolutions. If the texture has dimensions   2 n*2 m, there are  max(n m)+1 mipmaps. The first
+%% mipmap is the original texture, with dimensions   2 n*2 m. Each subsequent mipmap has
+%% dimensions   2(k-1)*2(l-1), where   2 k*2 l are the dimensions of the previous mipmap, until either
+%%   k= 0 or   l= 0. At that point, subsequent mipmaps have dimension   1*2(l-1) or   2(k-1)*1 until
+%% the final mipmap, which has dimension   1*1. To define the mipmaps, call  {@link gl:texImage1D/8} 
+%% ,  {@link gl:texImage2D/9} ,  {@link gl:texImage3D/10} ,  {@link gl:copyTexImage1D/7} , or  {@link gl:copyTexImage2D/8} 
+%%  with the `level' argument indicating the order of the mipmaps. Level 0 is the original
+%% texture; level   max(n m) is the final   1*1 mipmap. 
+%%
+%%  `Params'  supplies a function for minifying the texture as one of the following: 
+%%
+%% `?GL_NEAREST':  Returns the value of the texture element that is nearest (in Manhattan
+%% distance) to the specified texture coordinates. 
+%%
+%% `?GL_LINEAR':  Returns the weighted average of the four texture elements that are
+%% closest to the specified texture coordinates. These can include items wrapped or repeated
+%% from other parts of a texture, depending on the values of `?GL_TEXTURE_WRAP_S' and `?GL_TEXTURE_WRAP_T'
+%% , and on the exact mapping. 
+%%
+%% `?GL_NEAREST_MIPMAP_NEAREST':  Chooses the mipmap that most closely matches the size
+%% of the pixel being textured and uses the `?GL_NEAREST' criterion (the texture element
+%% closest to the specified texture coordinates) to produce a texture value. 
+%%
+%% `?GL_LINEAR_MIPMAP_NEAREST':  Chooses the mipmap that most closely matches the size
+%% of the pixel being textured and uses the `?GL_LINEAR' criterion (a weighted average
+%% of the four texture elements that are closest to the specified texture coordinates) to
+%% produce a texture value. 
+%%
+%% `?GL_NEAREST_MIPMAP_LINEAR':  Chooses the two mipmaps that most closely match the
+%% size of the pixel being textured and uses the `?GL_NEAREST' criterion (the texture
+%% element closest to the specified texture coordinates ) to produce a texture value from
+%% each mipmap. The final texture value is a weighted average of those two values. 
+%%
+%% `?GL_LINEAR_MIPMAP_LINEAR':  Chooses the two mipmaps that most closely match the
+%% size of the pixel being textured and uses the `?GL_LINEAR' criterion (a weighted
+%% average of the texture elements that are closest to the specified texture coordinates)
+%% to produce a texture value from each mipmap. The final texture value is a weighted average
+%% of those two values. 
+%%
+%%  As more texture elements are sampled in the minification process, fewer aliasing artifacts
+%% will be apparent. While the `?GL_NEAREST' and `?GL_LINEAR' minification functions
+%% can be faster than the other four, they sample only one or multiple texture elements to
+%% determine the texture value of the pixel being rendered and can produce moire patterns
+%% or ragged transitions. The initial value of `?GL_TEXTURE_MIN_FILTER' is `?GL_NEAREST_MIPMAP_LINEAR'
+%% . 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_MAG_FILTER':  The texture magnification function is used whenever the
+%% level-of-detail function used when sampling from the texture determines that the texture
+%% should be magified. It sets the texture magnification function to either `?GL_NEAREST'
+%%  or `?GL_LINEAR' (see below). `?GL_NEAREST' is generally faster than `?GL_LINEAR'
+%% , but it can produce textured images with sharper edges because the transition between
+%% texture elements is not as smooth. The initial value of `?GL_TEXTURE_MAG_FILTER' is `?GL_LINEAR'
+%% . 
+%%
+%% `?GL_NEAREST':  Returns the value of the texture element that is nearest (in Manhattan
+%% distance) to the specified texture coordinates. 
+%%
+%% `?GL_LINEAR':  Returns the weighted average of the texture elements that are closest
+%% to the specified texture coordinates. These can include items wrapped or repeated from
+%% other parts of a texture, depending on the values of `?GL_TEXTURE_WRAP_S' and `?GL_TEXTURE_WRAP_T'
+%% , and on the exact mapping. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_MIN_LOD':  Sets the minimum level-of-detail parameter. This floating-point
+%% value limits the selection of highest resolution mipmap (lowest mipmap level). The initial
+%% value is -1000. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_MAX_LOD':  Sets the maximum level-of-detail parameter. This floating-point
+%% value limits the selection of the lowest resolution mipmap (highest mipmap level). The
+%% initial value is 1000. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_MAX_LEVEL':  Sets the index of the highest defined mipmap level. This
+%% is an integer value. The initial value is 1000. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_SWIZZLE_R':  Sets the swizzle that will be applied to the  r component
+%% of a texel before it is returned to the shader. Valid values for  `Param'  are `?GL_RED'
+%% , `?GL_GREEN', `?GL_BLUE', `?GL_ALPHA', `?GL_ZERO' and `?GL_ONE'.
+%% If `?GL_TEXTURE_SWIZZLE_R' is `?GL_RED', the value for  r will be taken from
+%% the first channel of the fetched texel. If `?GL_TEXTURE_SWIZZLE_R' is `?GL_GREEN'
+%% , the value for  r will be taken from the second channel of the fetched texel. If `?GL_TEXTURE_SWIZZLE_R'
+%%  is `?GL_BLUE', the value for  r will be taken from the third channel of the fetched
+%% texel. If `?GL_TEXTURE_SWIZZLE_R' is `?GL_ALPHA', the value for  r will be taken
+%% from the fourth channel of the fetched texel. If `?GL_TEXTURE_SWIZZLE_R' is `?GL_ZERO'
+%% , the value for  r will be subtituted with  0.0. If `?GL_TEXTURE_SWIZZLE_R' is `?GL_ONE'
+%% , the value for  r will be subtituted with  1.0. The initial value is `?GL_RED'. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_SWIZZLE_G':  Sets the swizzle that will be applied to the  g component
+%% of a texel before it is returned to the shader. Valid values for  `Param'  and their
+%% effects are similar to those of `?GL_TEXTURE_SWIZZLE_R'. The initial value is `?GL_GREEN'
+%% . 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_SWIZZLE_B':  Sets the swizzle that will be applied to the  b component
+%% of a texel before it is returned to the shader. Valid values for  `Param'  and their
+%% effects are similar to those of `?GL_TEXTURE_SWIZZLE_R'. The initial value is `?GL_BLUE'
+%% . 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_SWIZZLE_A':  Sets the swizzle that will be applied to the  a component
+%% of a texel before it is returned to the shader. Valid values for  `Param'  and their
+%% effects are similar to those of `?GL_TEXTURE_SWIZZLE_R'. The initial value is `?GL_ALPHA'
+%% . 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_SWIZZLE_RGBA':  Sets the swizzles that will be applied to the  r,  g, 
+%% b, and  a components of a texel before they are returned to the shader. Valid values for  `Params' 
+%%  and their effects are similar to those of `?GL_TEXTURE_SWIZZLE_R', except that all
+%% channels are specified simultaneously. Setting the value of `?GL_TEXTURE_SWIZZLE_RGBA'
+%%  is equivalent (assuming no errors are generated) to setting the parameters of each of `?GL_TEXTURE_SWIZZLE_R'
+%% , `?GL_TEXTURE_SWIZZLE_G', `?GL_TEXTURE_SWIZZLE_B', and `?GL_TEXTURE_SWIZZLE_A'
+%%  successively. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_WRAP_S':  Sets the wrap parameter for texture coordinate   s to either `?GL_CLAMP_TO_EDGE'
+%% , `?GL_CLAMP_TO_BORDER', `?GL_MIRRORED_REPEAT', or `?GL_REPEAT'. `?GL_CLAMP_TO_EDGE'
+%%  causes   s coordinates to be clamped to the range  [(1 2/N) 1-(1 2/N)], where   N is the size of the texture
+%% in the direction of clamping. `?GL_CLAMP_TO_BORDER' evaluates  s coordinates in a
+%% similar manner to `?GL_CLAMP_TO_EDGE'. However, in cases where clamping would have
+%% occurred in `?GL_CLAMP_TO_EDGE' mode, the fetched texel data is substituted with
+%% the values specified by `?GL_TEXTURE_BORDER_COLOR'. `?GL_REPEAT' causes the
+%% integer part of the   s coordinate to be ignored; the GL uses only the fractional part,
+%% thereby creating a repeating pattern. `?GL_MIRRORED_REPEAT' causes the   s coordinate
+%% to be set to the fractional part of the texture coordinate if the integer part of   s
+%% is even; if the integer part of   s is odd, then the   s texture coordinate is set to   1-
+%% frac(s), where   frac(s) represents the fractional part of  s. Initially, `?GL_TEXTURE_WRAP_S'
+%%  is set to `?GL_REPEAT'. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_WRAP_T':  Sets the wrap parameter for texture coordinate   t to either `?GL_CLAMP_TO_EDGE'
+%% , `?GL_CLAMP_TO_BORDER', `?GL_MIRRORED_REPEAT', or `?GL_REPEAT'. See the
+%% discussion under `?GL_TEXTURE_WRAP_S'. Initially, `?GL_TEXTURE_WRAP_T' is set
+%% to `?GL_REPEAT'. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_WRAP_R':  Sets the wrap parameter for texture coordinate   r to either `?GL_CLAMP_TO_EDGE'
+%% , `?GL_CLAMP_TO_BORDER', `?GL_MIRRORED_REPEAT', or `?GL_REPEAT'. See the
+%% discussion under `?GL_TEXTURE_WRAP_S'. Initially, `?GL_TEXTURE_WRAP_R' is set

+%% describe how the image is represented in memory. 
+%%
+%%  If  `Target'  is `?GL_PROXY_TEXTURE_1D', no data is read from  `Data' , but
+%% all of the texture image state is recalculated, checked for consistency, and checked against

+%% error (see  {@link gl:getError/0} ). To query for an entire mipmap array, use an image array
+%% level greater than or equal to 1. 
+%%
+%%  If  `Target'  is `?GL_TEXTURE_1D', data is read from  `Data'  as a sequence
+%% of signed or unsigned bytes, shorts, or longs, or single-precision floating-point values,
+%% depending on  `Type' . These values are grouped into sets of one, two, three, or four

+%% 1-bit elements, with bit ordering determined by `?GL_UNPACK_LSB_FIRST' (see  {@link gl:pixelStoref/2} 
+%% ). 
+%%
+%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_UNPACK_BUFFER' target
+%%  (see  {@link gl:bindBuffer/2} ) while a texture image is specified,  `Data'  is treated

+%%
+%%  The first element corresponds to the left end of the texture array. Subsequent elements
+%% progress left-to-right through the remaining texels in the texture array. The final element

+%%
+%%  `Format'  determines the composition of each element in  `Data' . It can assume
+%% one of these symbolic values: 
+%%
+%% `?GL_RED':  Each element is a single red component. The GL converts it to floating
+%% point and assembles it into an RGBA element by attaching 0 for green and blue, and 1 for
+%% alpha. Each component is then multiplied by the signed scale factor `?GL_c_SCALE',
+%% added to the signed bias `?GL_c_BIAS', and clamped to the range [0,1]. 
+%%
+%% `?GL_RG':  Each element is a single red/green double The GL converts it to floating
+%% point and assembles it into an RGBA element by attaching 0 for blue, and 1 for alpha.
+%% Each component is then multiplied by the signed scale factor `?GL_c_SCALE', added
+%% to the signed bias `?GL_c_BIAS', and clamped to the range [0,1]. 
+%%
+%% `?GL_RGB'
+%%
+%% `?GL_BGR':  Each element is an RGB triple. The GL converts it to floating point and
+%% assembles it into an RGBA element by attaching 1 for alpha. Each component is then multiplied
+%% by the signed scale factor `?GL_c_SCALE', added to the signed bias `?GL_c_BIAS',
+%% and clamped to the range [0,1]. 
+%%
+%% `?GL_RGBA'
+%%

+%% and clamped to the range [0,1]. 
+%%
+%% `?GL_DEPTH_COMPONENT':  Each element is a single depth value. The GL converts it
+%% to floating point, multiplies by the signed scale factor `?GL_DEPTH_SCALE', adds
+%% the signed bias `?GL_DEPTH_BIAS', and clamps to the range [0,1]. 
+%%
+%%  If an application wants to store the texture at a certain resolution or in a certain
+%% format, it can request the resolution and format with  `InternalFormat' . The GL will
+%% choose an internal representation that closely approximates that requested by  `InternalFormat'

+%% below 
+%%
+%%  Finally,  `InternalFormat'  may also be one of the generic or compressed compressed

+%% @doc Bind a named texture to a texturing target
+%%
+%% ``gl:bindTexture'' lets you create or use a named texture. Calling ``gl:bindTexture''
+%% with  `Target'  set to `?GL_TEXTURE_1D', `?GL_TEXTURE_2D', `?GL_TEXTURE_3D'
+%% , or `?GL_TEXTURE_1D_ARRAY', `?GL_TEXTURE_2D_ARRAY', `?GL_TEXTURE_RECTANGLE'
+%% , `?GL_TEXTURE_CUBE_MAP', `?GL_TEXTURE_2D_MULTISAMPLE' or `?GL_TEXTURE_2D_MULTISAMPLE_ARRAY'
+%%  and  `Texture'  set to the name of the new texture binds the texture name to the target.
+%% When a texture is bound to a target, the previous binding for that target is automatically
+%% broken. 
+%%
+%%  Texture names are unsigned integers. The value zero is reserved to represent the default
+%% texture for each texture target. Texture names and the corresponding texture contents
+%% are local to the shared object space of the current GL rendering context; two rendering
+%% contexts share texture names only if they explicitly enable sharing between contexts through
+%% the appropriate GL windows interfaces functions. 
+%%
+%%  You must use  {@link gl:genTextures/1}  to generate a set of new texture names. 
+%%
+%%  When a texture is first bound, it assumes the specified target: A texture first bound
+%% to `?GL_TEXTURE_1D' becomes one-dimensional texture, a texture first bound to `?GL_TEXTURE_2D'
+%%  becomes two-dimensional texture, a texture first bound to `?GL_TEXTURE_3D' becomes
+%% three-dimensional texture, a texture first bound to `?GL_TEXTURE_1D_ARRAY' becomes
+%% one-dimensional array texture, a texture first bound to `?GL_TEXTURE_2D_ARRAY' becomes
+%% two-dimensional arary texture, a texture first bound to `?GL_TEXTURE_RECTANGLE' becomes
+%% rectangle texture, a, texture first bound to `?GL_TEXTURE_CUBE_MAP' becomes a cube-mapped
+%% texture, a texture first bound to `?GL_TEXTURE_2D_MULTISAMPLE' becomes a two-dimensional
+%% multisampled texture, and a texture first bound to `?GL_TEXTURE_2D_MULTISAMPLE_ARRAY'
+%% becomes a two-dimensional multisampled array texture. The state of a one-dimensional texture
+%% immediately after it is first bound is equivalent to the state of the default `?GL_TEXTURE_1D'
+%%  at GL initialization, and similarly for the other texture types. 
+%%
+%%  While a texture is bound, GL operations on the target to which it is bound affect the
+%% bound texture, and queries of the target to which it is bound return state from the bound
+%% texture.  In effect, the texture targets become aliases for the textures currently bound
+%% to them, and the texture name zero refers to the default textures that were bound to them
+%% at initialization. 
+%%
+%%  A texture binding created with ``gl:bindTexture'' remains active until a different
+%% texture is bound to the same target, or until the bound texture is deleted with  {@link gl:deleteTextures/1} 
+%% . 
+%%
+%%  Once created, a named texture may be re-bound to its same original target as often as
+%% needed. It is usually much faster to use ``gl:bindTexture'' to bind an existing named
+%% texture to one of the texture targets than it is to reload the texture image using  {@link gl:texImage1D/8} 
+%% ,  {@link gl:texImage2D/9} ,  {@link gl:texImage3D/10}  or another similar function.

+%%  `Query'  can assume the following values:

+%% `?GL_COEFF':  `V'  returns the control points for the evaluator function. One-dimensional

+%%  control points. Each control point consists of one, two, three, or four integer, single-precision
+%% floating-point, or double-precision floating-point values, depending on the type of the

+%% @doc Evaluate enabled one- and two-dimensional maps
+%%
+%% ``gl:evalCoord1'' evaluates enabled one-dimensional maps at argument  `U' . ``gl:evalCoord2''
+%%  does the same for two-dimensional maps using two domain values,  `U'  and  `V' .
+%% To define a map, call  {@link gl:map1d/6}  and  {@link gl:map1d/6} ; to enable and disable it,
+%% call  {@link gl:enable/1}  and  {@link gl:enable/1} . 
+%%
+%%  When one of the ``gl:evalCoord'' commands is issued, all currently enabled maps of
+%% the indicated dimension are evaluated. Then, for each enabled map, it is as if the corresponding
+%% GL command had been issued with the computed value. That is, if `?GL_MAP1_INDEX' or `?GL_MAP2_INDEX'
+%%  is enabled, a  {@link gl:indexd/1}  command is simulated. If `?GL_MAP1_COLOR_4' or `?GL_MAP2_COLOR_4'
+%%  is enabled, a  {@link gl:color3b/3}  command is simulated. If `?GL_MAP1_NORMAL' or `?GL_MAP2_NORMAL'
+%%  is enabled, a normal vector is produced, and if any of `?GL_MAP1_TEXTURE_COORD_1', `?GL_MAP1_TEXTURE_COORD_2'
+%% , `?GL_MAP1_TEXTURE_COORD_3', `?GL_MAP1_TEXTURE_COORD_4', `?GL_MAP2_TEXTURE_COORD_1'
+%% , `?GL_MAP2_TEXTURE_COORD_2', `?GL_MAP2_TEXTURE_COORD_3', or `?GL_MAP2_TEXTURE_COORD_4'
+%%  is enabled, then an appropriate  {@link gl:texCoord1d/1}  command is simulated. 
+%%
+%%  For color, color index, normal, and texture coordinates the GL uses evaluated values
+%% instead of current values for those evaluations that are enabled, and current values otherwise,
+%% However, the evaluated values do not update the current values. Thus, if  {@link gl:vertex2d/2} 
+%%  commands are interspersed with ``gl:evalCoord'' commands, the color, normal, and texture
+%% coordinates associated with the  {@link gl:vertex2d/2}  commands are not affected by the values
+%% generated by the ``gl:evalCoord'' commands, but only by the most recent  {@link gl:color3b/3} 
+%% ,  {@link gl:indexd/1} ,  {@link gl:normal3b/3} , and  {@link gl:texCoord1d/1}  commands. 
+%%
+%%  No commands are issued for maps that are not enabled. If more than one texture evaluation
+%% is enabled for a particular dimension (for example, `?GL_MAP2_TEXTURE_COORD_1' and `?GL_MAP2_TEXTURE_COORD_2'
+%% ), then only the evaluation of the map that produces the larger number of coordinates
+%% (in this case, `?GL_MAP2_TEXTURE_COORD_2') is carried out. `?GL_MAP1_VERTEX_4'
+%% overrides `?GL_MAP1_VERTEX_3', and `?GL_MAP2_VERTEX_4' overrides `?GL_MAP2_VERTEX_3'
+%% , in the same manner. If neither a three- nor a four-component vertex map is enabled for
+%% the specified dimension, the ``gl:evalCoord'' command is ignored. 
+%%
+%%  If you have enabled automatic normal generation, by calling  {@link gl:enable/1}  with argument
+%% `?GL_AUTO_NORMAL', ``gl:evalCoord2'' generates surface normals analytically, regardless
+%% of the contents or enabling of the `?GL_MAP2_NORMAL' map. Let 
+%%
+%%  m=((&amp;PartialD; p)/(&amp;PartialD; u))*((&amp;PartialD; p)/(&amp;PartialD; v))
+%%
+%%  Then the generated normal   n is  n= m/(||m||)
+%%
+%%  If automatic normal generation is disabled, the corresponding normal map `?GL_MAP2_NORMAL'
+%% , if enabled, is used to produce a normal. If neither automatic normal generation nor
+%% a normal map is enabled, no normal is generated for ``gl:evalCoord2'' commands.

+%% @doc Controls feedback mode
+%%
+%%  The ``gl:feedbackBuffer'' function controls feedback. Feedback, like selection, is
+%% a GL mode. The mode is selected by calling  {@link gl:renderMode/1}  with `?GL_FEEDBACK'.
+%% When the GL is in feedback mode, no pixels are produced by rasterization. Instead, information
+%% about primitives that would have been rasterized is fed back to the application using
+%% the GL. 
+%%
+%% ``gl:feedbackBuffer'' has three arguments:  `Buffer'  is a pointer to an array of
+%% floating-point values into which feedback information is placed.  `Size'  indicates
+%% the size of the array.  `Type'  is a symbolic constant describing the information that
+%% is fed back for each vertex. ``gl:feedbackBuffer'' must be issued before feedback mode
+%% is enabled (by calling  {@link gl:renderMode/1}  with argument `?GL_FEEDBACK'). Setting
+%% `?GL_FEEDBACK' without establishing the feedback buffer, or calling ``gl:feedbackBuffer''
+%%  while the GL is in feedback mode, is an error. 
+%%
+%%  When  {@link gl:renderMode/1}  is called while in feedback mode, it returns the number of
+%% entries placed in the feedback array and resets the feedback array pointer to the base
+%% of the feedback buffer. The returned value never exceeds  `Size' . If the feedback
+%% data required more room than was available in  `Buffer' ,  {@link gl:renderMode/1}  returns
+%% a negative value. To take the GL out of feedback mode, call  {@link gl:renderMode/1}  with
+%% a parameter value other than `?GL_FEEDBACK'. 
+%%
+%%  While in feedback mode, each primitive, bitmap, or pixel rectangle that would be rasterized
+%% generates a block of values that are copied into the feedback array. If doing so would
+%% cause the number of entries to exceed the maximum, the block is partially written so as
+%% to fill the array (if there is any room left at all), and an overflow flag is set. Each
+%% block begins with a code indicating the primitive type, followed by values that describe
+%% the primitive's vertices and associated data. Entries are also written for bitmaps and
+%% pixel rectangles. Feedback occurs after polygon culling and  {@link gl:polygonMode/2}  interpretation
+%% of polygons has taken place, so polygons that are culled are not returned in the feedback
+%% buffer. It can also occur after polygons with more than three edges are broken up into
+%% triangles, if the GL implementation renders polygons by performing this decomposition. 
+%%
+%%  The  {@link gl:passThrough/1}  command can be used to insert a marker into the feedback
+%% buffer. See  {@link gl:passThrough/1} . 
+%%
+%%  Following is the grammar for the blocks of values written into the feedback buffer. Each
+%% primitive is indicated with a unique identifying value followed by some number of vertices.
+%% Polygon entries include an integer value indicating how many vertices follow. A vertex
+%% is fed back as some number of floating-point values, as determined by  `Type' . Colors
+%% are fed back as four values in RGBA mode and one value in color index mode.

+%%
+%%  A programmer can use selection to determine which primitives are drawn into some region
+%% of a window. The region is defined by the current modelview and perspective matrices. 
+%%
+%%  In selection mode, no pixel fragments are produced from rasterization. Instead, if a
+%% primitive or a raster position intersects the clipping volume defined by the viewing frustum
+%% and the user-defined clipping planes, this primitive causes a selection hit. (With polygons,
+%% no hit occurs if the polygon is culled.) When a change is made to the name stack, or when
+%%  {@link gl:renderMode/1}  is called, a hit record is copied to  `Buffer'  if any hits
+%% have occurred since the last such event (name stack change or  {@link gl:renderMode/1}  call).
+%% The hit record consists of the number of names in the name stack at the time of the event,
+%% followed by the minimum and maximum depth values of all vertices that hit since the previous
+%% event, followed by the name stack contents, bottom name first. 
+%%
+%%  Depth values (which are in the range [0,1]) are multiplied by   2 32-1, before being
+%% placed in the hit record. 
+%%
+%%  An internal index into  `Buffer'  is reset to 0 whenever selection mode is entered.
+%% Each time a hit record is copied into  `Buffer' , the index is incremented to point
+%% to the cell just past the end of the block of names(emthat is, to the next available cell
+%% If the hit record is larger than the number of remaining locations in  `Buffer' , as
+%% much data as can fit is copied, and the overflow flag is set. If the name stack is empty
+%% when a hit record is copied, that record consists of 0 followed by the minimum and maximum

+%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_UNPACK_BUFFER' target
+%%  (see  {@link gl:bindBuffer/2} ) while a texture image is specified,  `Data'  is treated

+%%  The first element corresponds to the lower left corner of the texture image. Subsequent

+%% corresponds to the upper right corner of the texture image. 
+%%
+%%  `Format'  determines the composition of each element in  `Data' . It can assume
+%% one of these symbolic values: 
+%%
+%% `?GL_RED':  Each element is a single red component. The GL converts it to floating
+%% point and assembles it into an RGBA element by attaching 0 for green and blue, and 1 for
+%% alpha. Each component is then multiplied by the signed scale factor `?GL_c_SCALE',
+%% added to the signed bias `?GL_c_BIAS', and clamped to the range [0,1]. 
+%%
+%% `?GL_RG':  Each element is a red and green pair. The GL converts each to floating
+%% point and assembles it into an RGBA element by attaching 0 for blue, and 1 for alpha.
+%% Each component is then multiplied by the signed scale factor `?GL_c_SCALE', added
+%% to the signed bias `?GL_c_BIAS', and clamped to the range [0,1]. 
+%%
+%% `?GL_RGB'
+%%
+%% `?GL_BGR':  Each element is an RGB triple. The GL converts it to floating point and
+%% assembles it into an RGBA element by attaching 1 for alpha. Each component is then multiplied
+%% by the signed scale factor `?GL_c_SCALE', added to the signed bias `?GL_c_BIAS',
+%% and clamped to the range [0,1]. 
+%%
+%% `?GL_RGBA'
+%%
+%% `?GL_BGRA':  Each element contains all four components. Each component is multiplied
+%% by the signed scale factor `?GL_c_SCALE', added to the signed bias `?GL_c_BIAS',
+%% and clamped to the range [0,1]. 
+%%
+%%  If an application wants to store the texture at a certain resolution or in a certain
+%% format, it can request the resolution and format with  `InternalFormat' . The GL will
+%% choose an internal representation that closely approximates that requested by  `InternalFormat' 
+%% , but it may not match exactly. (The representations specified by `?GL_RED', `?GL_RG'
+%% , `?GL_RGB', and `?GL_RGBA' must match exactly.) 
+%%
+%%  `InternalFormat'  may be one of the base internal formats shown in Table 1, below 
+%%
+%%  `InternalFormat'  may also be one of the sized internal formats shown in Table 2,
+%% below 
+%%
+%%  Finally,  `InternalFormat'  may also be one of the generic or compressed compressed
+%% texture formats shown in Table 3 below 
+%%
+%%   If the  `InternalFormat'  parameter is one of the generic compressed formats,  `?GL_COMPRESSED_RED'
+%% , `?GL_COMPRESSED_RG',  `?GL_COMPRESSED_RGB', or  `?GL_COMPRESSED_RGBA',
+%% the GL will replace the internal format with the symbolic constant for a specific internal
+%% format and compress the texture before storage. If no corresponding internal format is
+%% available, or the GL can not compress that image for any reason, the internal format is
+%% instead replaced with a corresponding base internal format. 
+%%
+%%  If the  `InternalFormat'  parameter is     `?GL_SRGB',    `?GL_SRGB8',    `?GL_SRGB_ALPHA'
+%% , or    `?GL_SRGB8_ALPHA8', the texture is treated as if the red, green, blue, or
+%% luminance components are encoded in the sRGB color space. Any alpha component is left
+%% unchanged. The conversion from the sRGB encoded component      c s    to a linear component
+%%      c l is:   
+%%
+%%  c l={ c s/12.92if c s&amp;le; 0.04045( c s+0.055/1.055) 2.4if c s&gt; 0.04045
+%%
+%%     Assume        c s    is the sRGB component in the range [0,1]. 
+%%
+%%  Use the `?GL_PROXY_TEXTURE_3D' target to try out a resolution and format. The implementation

+%% @doc Define a color lookup table
+%%
+%% ``gl:colorTable'' may be used in two ways: to test the actual size and color resolution
+%% of a lookup table given a particular set of parameters, or to load the contents of a color
+%% lookup table. Use the targets `?GL_PROXY_*' for the first case and the other targets
+%% for the second case. 
+%%
+%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_UNPACK_BUFFER' target
+%%  (see  {@link gl:bindBuffer/2} ) while a color table is specified,  `Data'  is treated
+%% as a byte offset into the buffer object's data store. 
+%%
+%%  If  `Target'  is `?GL_COLOR_TABLE', `?GL_POST_CONVOLUTION_COLOR_TABLE', or `?GL_POST_COLOR_MATRIX_COLOR_TABLE'
+%% , ``gl:colorTable'' builds a color lookup table from an array of pixels. The pixel array
+%% specified by  `Width' ,  `Format' ,  `Type' , and  `Data'  is extracted from
+%% memory and processed just as if  {@link gl:drawPixels/5}  were called, but processing stops
+%% after the final expansion to RGBA is completed. 
+%%
+%%  The four scale parameters and the four bias parameters that are defined for the table
+%% are then used to scale and bias the R, G, B, and A components of each pixel. (Use ``gl:colorTableParameter''
+%%  to set these scale and bias parameters.) 
+%%
+%%  Next, the R, G, B, and A values are clamped to the range  [0 1]. Each pixel is then converted
+%% to the internal format specified by  `Internalformat' . This conversion simply maps
+%% the component values of the pixel (R, G, B, and A) to the values included in the internal
+%% format (red, green, blue, alpha, luminance, and intensity). The mapping is as follows: 
+%%
+%% <table><tbody><tr><td>` Internal Format '</td><td>` Red '</td><td>` Green '</td>
+%% <td>` Blue '</td><td>` Alpha '</td><td>` Luminance '</td><td>` Intensity '
+%% </td></tr></tbody><tbody><tr><td>`?GL_ALPHA'</td><td></td><td></td><td></td><td> A </td>
+%% <td></td><td></td></tr><tr><td>`?GL_LUMINANCE'</td><td></td><td></td><td></td><td></td>
+%% <td> R </td><td></td></tr><tr><td>`?GL_LUMINANCE_ALPHA'</td><td></td><td></td><td></td>
+%% <td> A </td><td> R </td><td></td></tr><tr><td>`?GL_INTENSITY'</td><td></td><td></td><td>
+%% </td><td></td><td></td><td> R </td></tr><tr><td>`?GL_RGB'</td><td> R </td><td> G </td>
+%% <td> B </td><td></td><td></td><td></td></tr><tr><td>`?GL_RGBA'</td><td> R </td><td>
+%% G </td><td> B </td><td> A </td><td></td><td></td></tr></tbody></table>
+%%
+%%  Finally, the red, green, blue, alpha, luminance, and/or intensity components of the resulting
+%% pixels are stored in the color table. They form a one-dimensional table with indices in
+%% the range [0 width-1]. 
+%%
+%%  If  `Target'  is `?GL_PROXY_*', ``gl:colorTable'' recomputes and stores the
+%% values of the proxy color table's state variables `?GL_COLOR_TABLE_FORMAT', `?GL_COLOR_TABLE_WIDTH'
+%% , `?GL_COLOR_TABLE_RED_SIZE', `?GL_COLOR_TABLE_GREEN_SIZE', `?GL_COLOR_TABLE_BLUE_SIZE'
+%% , `?GL_COLOR_TABLE_ALPHA_SIZE', `?GL_COLOR_TABLE_LUMINANCE_SIZE', and `?GL_COLOR_TABLE_INTENSITY_SIZE'
+%% . There is no effect on the image or state of any actual color table. If the specified
+%% color table is too large to be supported, then all the proxy state variables listed above
+%% are set to zero. Otherwise, the color table could be supported by ``gl:colorTable''
+%% using the corresponding non-proxy target, and the proxy state variables are set as if
+%% that target were being defined. 
+%%
+%%  The proxy state variables can be retrieved by calling  {@link gl:getColorTableParameterfv/2} 
+%% with a target of `?GL_PROXY_*'. This allows the application to decide if a particular
+%% ``gl:colorTable'' command would succeed, and to determine what the resulting color table
+%% attributes would be. 
+%%
+%%  If a color table is enabled, and its width is non-zero, then its contents are used to
+%% replace a subset of the components of each RGBA pixel group, based on the internal format
+%% of the table. 
+%%
+%%  Each pixel group has color components (R, G, B, A) that are in the range  [0.0 1.0]. The color
+%% components are rescaled to the size of the color lookup table to form an index. Then a
+%% subset of the components based on the internal format of the table are replaced by the
+%% table entry selected by that index. If the color components and contents of the table
+%% are represented as follows: 
+%%
+%% <table><tbody><tr><td>` Representation '</td><td>` Meaning '</td></tr></tbody><tbody>
+%% <tr><td>r</td><td> Table index computed from R</td></tr><tr><td>g</td><td> Table index
+%% computed from G</td></tr><tr><td>b</td><td> Table index computed from B</td></tr><tr><td>a
+%% </td><td> Table index computed from A</td></tr><tr><td>L[i]</td><td> Luminance value at
+%% table index i</td></tr><tr><td>I[i]</td><td> Intensity value at table index i</td></tr><tr>
+%% <td>R[i]</td><td> Red value at table index i</td></tr><tr><td>G[i]</td><td> Green value
+%% at table index i</td></tr><tr><td>B[i]</td><td> Blue value at table index i</td></tr><tr><td>
+%% A[i]</td><td> Alpha value at table index i</td></tr></tbody></table>
+%%
+%%  then the result of color table lookup is as follows: 
+%%
+%% <table><tbody><tr><td></td><td>` Resulting Texture Components '</td></tr><tr><td>` Table Internal Format '
+%% </td><td>` R '</td><td>` G '</td><td>` B '</td><td>` A '</td></tr></tbody>
+%% <tbody><tr><td>`?GL_ALPHA'</td><td>R</td><td>G</td><td>B</td><td>A[a]</td></tr><tr><td>
+%% `?GL_LUMINANCE'</td><td>L[r]</td><td>L[g]</td><td>L[b]</td><td>At</td></tr><tr><td>`?GL_LUMINANCE_ALPHA'
+%% </td><td>L[r]</td><td>L[g]</td><td>L[b]</td><td>A[a]</td></tr><tr><td>`?GL_INTENSITY'</td>
+%% <td>I[r]</td><td>I[g]</td><td>I[b]</td><td>I[a]</td></tr><tr><td>`?GL_RGB'</td><td>R[r]
+%% </td><td>G[g]</td><td>B[b]</td><td>A</td></tr><tr><td>`?GL_RGBA'</td><td>R[r]</td><td>
+%% G[g]</td><td>B[b]</td><td>A[a]</td></tr></tbody></table>
+%%
+%%  When `?GL_COLOR_TABLE' is enabled, the colors resulting from the pixel map operation
+%% (if it is enabled) are mapped by the color lookup table before being passed to the convolution
+%% operation. The colors resulting from the convolution operation are modified by the post
+%% convolution color lookup table when `?GL_POST_CONVOLUTION_COLOR_TABLE' is enabled.
+%% These modified colors are then sent to the color matrix operation. Finally, if `?GL_POST_COLOR_MATRIX_COLOR_TABLE'
+%%  is enabled, the colors resulting from the color matrix operation are mapped by the post
+%% color matrix color lookup table before being used by the histogram operation.

+%% @doc Define a separable two-dimensional convolution filter
+%%
+%% ``gl:separableFilter2D'' builds a two-dimensional separable convolution filter kernel
+%% from two arrays of pixels. 
+%%
+%%  The pixel arrays specified by ( `Width' ,  `Format' ,  `Type' ,  `Row' )
+%% and ( `Height' ,  `Format' ,  `Type' ,  `Column' ) are processed just as if
+%% they had been passed to  {@link gl:drawPixels/5} , but processing stops after the final expansion
+%% to RGBA is completed. 
+%%
+%%  If a non-zero named buffer object is bound to the `?GL_PIXEL_UNPACK_BUFFER' target
+%%  (see  {@link gl:bindBuffer/2} ) while a convolution filter is specified,  `Row'  and  `Column' 
+%%  are treated as byte offsets into the buffer object's data store. 
+%%
+%%  Next, the R, G, B, and A components of all pixels in both arrays are scaled by the four
+%% separable 2D `?GL_CONVOLUTION_FILTER_SCALE' parameters and biased by the four separable
+%% 2D `?GL_CONVOLUTION_FILTER_BIAS' parameters. (The scale and bias parameters are set
+%% by  {@link gl:convolutionParameterf/3}  using the `?GL_SEPARABLE_2D' target and the names
+%% `?GL_CONVOLUTION_FILTER_SCALE' and `?GL_CONVOLUTION_FILTER_BIAS'. The parameters
+%% themselves are vectors of four values that are applied to red, green, blue, and alpha,
+%% in that order.) The R, G, B, and A values are not clamped to [0,1] at any time during
+%% this process. 
+%%
+%%  Each pixel is then converted to the internal format specified by  `Internalformat' .
+%% This conversion simply maps the component values of the pixel (R, G, B, and A) to the
+%% values included in the internal format (red, green, blue, alpha, luminance, and intensity).
+%% The mapping is as follows: <table><tbody><tr><td>` Internal Format '</td><td>` Red '
+%% </td><td>` Green '</td><td>` Blue '</td><td>` Alpha '</td><td>` Luminance '
+%% </td><td>` Intensity '</td></tr></tbody><tbody><tr><td>`?GL_LUMINANCE'</td><td></td>

+%% <td> R </td><td> G </td><td> B </td><td></td><td></td><td></td></tr><tr><td>`?GL_RGBA'
+%% </td><td> R </td><td> G </td><td> B </td><td> A </td><td></td><td></td></tr></tbody></table>
+%% 
+%%
+%%  The red, green, blue, alpha, luminance, and/or intensity components of the resulting
+%% pixels are stored in floating-point rather than integer format. They form two one-dimensional
+%% filter kernel images. The row image is indexed by coordinate `i' starting at zero
+%% and increasing from left to right. Each location in the row image is derived from element
+%% `i' of  `Row' . The column image is indexed by coordinate `j' starting at
+%% zero and increasing from bottom to top. Each location in the column image is derived from
+%% element `j' of  `Column' . 
+%%
+%%  Note that after a convolution is performed, the resulting color components are also scaled
+%% by their corresponding `?GL_POST_CONVOLUTION_c_SCALE' parameters and biased by their
+%% corresponding `?GL_POST_CONVOLUTION_c_BIAS' parameters (where `c' takes on the

+%% ``gl:multiTexCoord'' specifies texture coordinates in one, two, three, or four dimensions.
+%% ``gl:multiTexCoord1'' sets the current texture coordinates to  (s 0 0 1); a call to ``gl:multiTexCoord2''
+%%  sets them to  (s t 0 1). Similarly, ``gl:multiTexCoord3'' specifies the texture coordinates as (s
+%%  t r 1),
+%% and ``gl:multiTexCoord4'' defines all four components explicitly as (s t r q). 
+%%
+%%  The current texture coordinates are part of the data that is associated with each vertex
+%% and with the current raster position. Initially, the values for (s t r q) are  (0 0 0 1).

+%% @doc Replace the current matrix with the specified row-major ordered matrix

+%% ``gl:loadTransposeMatrix'' replaces the current matrix with the one whose elements are
+%% specified by  `M' . The current matrix is the projection matrix, modelview matrix,
+%% or texture matrix, depending on the current matrix mode (see  {@link gl:matrixMode/1} ). 
+%%
+%%  The current matrix, M, defines a transformation of coordinates. For instance, assume
+%% M refers to the modelview matrix. If   v=(v[0] v[1] v[2] v[3]) is the set of object coordinates of a vertex,
+%% and  `M'  points to an array of   16 single- or double-precision floating-point values
+%%   m={m[0] m[1] ... m[15]}, then the modelview transformation   M(v) does the following:

+%%
+%%  Projection and texture transformations are similarly defined.

+%%
+%%  Buffer object names are unsigned integers. The value zero is reserved, but there is no
+%% default buffer object for each buffer object target. Instead,  `Buffer'  set to zero
+%% effectively unbinds any buffer object previously bound, and restores client memory usage
+%% for that buffer object target (if supported for that target). Buffer object names and
+%% the corresponding buffer object contents are local to the shared object space of the current
+%% GL rendering context; two rendering contexts share buffer object names only if they explicitly
+%% enable sharing between contexts through the appropriate GL windows interfaces functions. 
+%%
+%%  {@link gl:genBuffers/1}  must be used to generate a set of unused buffer object names. 
+%%
+%%  The state of a buffer object immediately after it is first bound is an unmapped zero-sized
+%% memory buffer with `?GL_READ_WRITE' access and `?GL_STATIC_DRAW' usage. 
+%%
+%%  While a non-zero buffer object name is bound, GL operations on the target to which it
+%% is bound affect the bound buffer object, and queries of the target to which it is bound
+%% return state  from the bound buffer object. While buffer object name zero is bound, as
+%% in the initial state, attempts to modify or query state on the target to which it is bound
+%% generates an  `?GL_INVALID_OPERATION' error. 
+%%

+%% The commands ``gl:uniform{1|2|3|4}{f|i|ui}'' are used to change the value of the uniform

+%% specified uniform variable (e.g., `1' for float, int, unsigned int, bool; `2'
+%% for vec2, ivec2, uvec2, bvec2, etc.). The suffix `f' indicates that floating-point
+%% values are being passed; the suffix `i' indicates that integer values are being passed;
+%% the suffix `ui' indicates that unsigned integer values are being passed, and this
+%% type should also match the data type of the specified uniform variable. The `i' variants
+%% of this function should be used to provide values for uniform variables defined as int, ivec2
+%% , ivec3, ivec4, or arrays of these. The `ui' variants of this function should be
+%% used to provide values for uniform variables defined as unsigned int, uvec2, uvec3, uvec4,
+%% or arrays of these. The `f' variants should be used to provide values for uniform
+%% variables of type float, vec2, vec3, vec4, or arrays of these. Either the `i', `ui'
+%%  or `f' variants may be used to provide values for uniform variables of type bool, bvec2
+%% , bvec3, bvec4, or arrays of these. The uniform variable will be set to false if the input
+%% value is 0 or 0.0f, and it will be set to true otherwise.
+%%
+%% All active uniform variables defined in a program object are initialized to 0 when the
+%% program object is linked successfully. They retain the values assigned to them by a call
+%% to ``gl:uniform '' until the next successful link operation occurs on the program object,
+%% when they are once again initialized to 0.
+%%
+%% The commands ``gl:uniform{1|2|3|4}{f|i|ui}v'' can be used to modify a single uniform
+%% variable or a uniform variable array. These commands pass a count and a pointer to the
+%% values to be loaded into a uniform variable or a uniform variable array. A count of 1
+%% should be used if modifying the value of a single uniform variable, and a count of 1 or
+%% greater can be used to modify an entire array or part of an array. When loading `n'
+%% elements starting at an arbitrary position `m' in a uniform variable array, elements
+%% `m' + `n' - 1 in the array will be replaced with the new values. If  `M'  +  `N' 
+%%  - 1 is larger than the size of the uniform variable array, values for all array elements
+%% beyond the end of the array will be ignored. The number specified in the name of the command
+%% indicates the number of components for each element in  `Value' , and it should match
+%% the number of components in the data type of the specified uniform variable (e.g., `1'
+%%  for float, int, bool; `2' for vec2, ivec2, bvec2, etc.). The data type specified
+%% in the name of the command must match the data type for the specified uniform variable
+%% as described previously for ``gl:uniform{1|2|3|4}{f|i|ui}''.
+%%
+%% For uniform variable arrays, each element of the array is considered to be of the type
+%% indicated in the name of the command (e.g., ``gl:uniform3f'' or ``gl:uniform3fv''
+%% can be used to load a uniform variable array of type vec3). The number of elements of
+%% the uniform variable array to be modified is specified by  `Count' 
+%%
+%% The commands ``gl:uniformMatrix{2|3|4|2x3|3x2|2x4|4x2|3x4|4x3}fv''  are used to modify
+%% a matrix or an array of matrices. The numbers in the command name are interpreted as the
+%% dimensionality of the matrix. The number `2' indicates a 2 � 2 matrix (i.e., 4 values),
+%% the number `3' indicates a 3 � 3 matrix (i.e., 9 values), and the number `4'
+%% indicates a 4 � 4 matrix (i.e., 16 values). Non-square matrix dimensionality is explicit,
+%% with the first number representing the number of columns and the second number representing
+%% the number of rows. For example,  `2x4' indicates a 2 � 4 matrix with 2 columns and
+%% 4 rows (i.e., 8 values). If  `Transpose'  is `?GL_FALSE', each matrix is assumed
+%% to be supplied in column major order. If  `Transpose'  is `?GL_TRUE', each matrix
+%% is assumed to be supplied in row major order. The  `Count'  argument indicates the
+%% number of matrices to be passed. A count of 1 should be used if modifying the value of
+%% a single matrix, and a count greater than 1 can be used to modify an array of matrices.

--spec vertexAttrib1d(integer(),float()) -> ok.
+%% @doc Specifies the value of a generic vertex attribute
+%%
+%% The ``gl:vertexAttrib'' family of entry points allows an application to pass generic
+%% vertex attributes in numbered locations.
+%%
+%% Generic attributes are defined as four-component values that are organized into an array.
+%% The first entry of this array is numbered 0, and the size of the array is specified by
+%% the implementation-dependent constant `?GL_MAX_VERTEX_ATTRIBS'. Individual elements
+%% of this array can be modified with a ``gl:vertexAttrib'' call that specifies the index
+%% of the element to be modified and a value for that element.
+%%
+%% These commands can be used to specify one, two, three, or all four components of the generic
+%% vertex attribute specified by  `Index' . A `1' in the name of the command indicates
+%% that only one value is passed, and it will be used to modify the first component of the
+%% generic vertex attribute. The second and third components will be set to 0, and the fourth
+%% component will be set to 1. Similarly, a `2' in the name of the command indicates
+%% that values are provided for the first two components, the third component will be set
+%% to 0, and the fourth component will be set to 1. A `3' in the name of the command
+%% indicates that values are provided for the first three components and the fourth component
+%% will be set to 1, whereas a `4' in the name indicates that values are provided for
+%% all four components.
+%%
+%% The letters `s', `f', `i', `d', `ub', `us', and `ui'
+%% indicate whether the arguments are of type short, float, int, double, unsigned byte, unsigned
+%% short, or unsigned int. When `v' is appended to the name, the commands can take a
+%% pointer to an array of such values.
+%%
+%% Additional capitalized letters can indicate further alterations to the default behavior
+%% of the glVertexAttrib function:
+%%
+%%  The commands containing `N' indicate that  the arguments will be passed as fixed-point
+%% values that are  scaled to a normalized range according to the component  conversion rules
+%% defined by the OpenGL specification. Signed values are understood to represent fixed-point
+%% values in the range [-1,1], and unsigned values are understood to represent fixed-point
+%% values in the range [0,1]. 
+%%
+%%  The commands containing `I' indicate that  the arguments are extended to full signed
+%% or unsigned integers. 
+%%
+%%  The commands containing `P' indicate that  the arguments are stored as packed components
+%% within a larger natural type. 
+%%
+%%  The commands containing `L' indicate that the arguments are full 64-bit quantities
+%% and should be passed directly to shader inputs declared as 64-bit double precision types.
+%% 
+%%
+%% OpenGL Shading Language attribute variables are allowed to be of type mat2, mat3, or mat4.
+%% Attributes of these types may be loaded using the ``gl:vertexAttrib'' entry points.
+%% Matrices must be loaded into successive generic attribute slots in column major order,
+%% with one column of the matrix in each generic attribute slot.
+%%
+%% A user-defined attribute variable declared in a vertex shader can be bound to a generic
+%% attribute index by calling  {@link gl:bindAttribLocation/3} . This allows an application
+%% to use more descriptive variable names in a vertex shader. A subsequent change to the
+%% specified generic vertex attribute will be immediately reflected as a change to the corresponding
+%% attribute variable in the vertex shader.
+%%
+%% The binding between a generic vertex attribute index and a user-defined attribute variable
+%% in a vertex shader is part of the state of a program object, but the current value of
+%% the generic vertex attribute is not. The value of each generic vertex attribute is part
+%% of current state, just like standard vertex attributes, and it is maintained even if a
+%% different program object is used.
+%%
+%% An application may freely modify generic vertex attributes that are not bound to a named
+%% vertex shader attribute variable. These values are simply maintained as part of current
+%% state and will not be accessed by the vertex shader. If a generic vertex attribute bound
+%% to an attribute variable in a vertex shader is not updated while the vertex shader is
+%% executing, the vertex shader will repeatedly use the current value for the generic vertex
+%% attribute.

+%% @doc Define an array of generic vertex attribute data
+%%
+%% ``gl:vertexAttribPointer'', ``gl:vertexAttribIPointer'' and ``gl:vertexAttribLPointer''
+%%  specify the location and data format of the array of generic vertex attributes at index  `Index' 
+%%  to use when rendering.  `Size'  specifies the number of components per attribute and
+%% must be 1, 2, 3, 4, or `?GL_BGRA'.  `Type'  specifies the data type of each component,
+%% and  `Stride'  specifies the byte stride from one attribute to the next, allowing vertices
+%% and attributes to be packed into a single array or stored in separate arrays. 
+%%
+%%  For ``gl:vertexAttribPointer'', if  `Normalized'  is set to `?GL_TRUE', it
+%% indicates that values stored in an integer format are to be mapped to the range [-1,1]
+%% (for signed values) or [0,1] (for unsigned values) when they are accessed and converted
+%% to floating point. Otherwise, values will be converted to floats directly without normalization.
+%% 
+%%
+%%  For ``gl:vertexAttribIPointer'', only the integer types `?GL_BYTE', `?GL_UNSIGNED_BYTE'
+%% , `?GL_SHORT', `?GL_UNSIGNED_SHORT', `?GL_INT', `?GL_UNSIGNED_INT'
+%% are accepted. Values are always left as integer values. 
+%%
+%% ``gl:vertexAttribLPointer'' specifies state for a generic vertex attribute array associated
+%% with a shader attribute variable declared with 64-bit double precision components.  `Type' 
+%%  must be `?GL_DOUBLE'.  `Index' ,  `Size' , and  `Stride'  behave as described
+%% for ``gl:vertexAttribPointer'' and ``gl:vertexAttribIPointer''. 
+%%
+%%  If  `Pointer'  is not NULL, a non-zero named buffer object must be bound to the `?GL_ARRAY_BUFFER'
+%%  target (see  {@link gl:bindBuffer/2} ), otherwise an error is generated.  `Pointer' 
+%% is treated as a byte offset into the buffer object's data store. The buffer object binding
+%% (`?GL_ARRAY_BUFFER_BINDING') is saved as generic vertex attribute array state (`?GL_VERTEX_ATTRIB_ARRAY_BUFFER_BINDING'
+%% ) for index  `Index' . 
+%%
+%%  When a generic vertex attribute array is specified,  `Size' ,  `Type' ,  `Normalized' 
+%% ,  `Stride' , and  `Pointer'  are saved as vertex array state, in addition to the
+%% current vertex array buffer object binding. 
+%%
+%%  To enable and disable a generic vertex attribute array, call  {@link gl:disableVertexAttribArray/1} 
+%%  and  {@link gl:disableVertexAttribArray/1}  with  `Index' . If enabled, the generic vertex
+%% attribute array is used when  {@link gl:drawArrays/3} ,  {@link gl:multiDrawArrays/3} ,  {@link gl:drawElements/4} 
+%% , see `glMultiDrawElements', or  {@link gl:drawRangeElements/6}  is called.

+%% @doc Retrieve information about varying variables selected for transform feedback
+%%
+%%  Information about the set of varying variables in a linked program that will be captured
+%% during transform feedback may be retrieved by calling ``gl:getTransformFeedbackVarying''.
+%% ``gl:getTransformFeedbackVarying'' provides information about the varying variable selected
+%% by  `Index' . An  `Index'  of 0 selects the first varying variable specified in
+%% the  `Varyings'  array passed to  {@link gl:transformFeedbackVaryings/3} , and an  `Index' 
+%%  of `?GL_TRANSFORM_FEEDBACK_VARYINGS-1' selects the last such variable. 
+%%
+%%  The name of the selected varying is returned as a null-terminated string in  `Name' .
+%% The actual number of characters written into  `Name' , excluding the null terminator,
+%% is returned in  `Length' . If  `Length'  is NULL, no length is returned. The maximum
+%% number of characters that may be written into  `Name' , including the null terminator,
+%% is specified by  `BufSize' . 
+%%
+%%  The length of the longest varying name in program is given by `?GL_TRANSFORM_FEEDBACK_VARYING_MAX_LENGTH'
+%% , which can be queried with  {@link gl:getProgramiv/2} . 
+%%
+%%  For the selected varying variable, its type is returned into  `Type' . The size of
+%% the varying is returned into  `Size' . The value in  `Size'  is in units of the
+%% type returned in  `Type' . The type returned can be any of the scalar, vector, or matrix
+%% attribute types returned by  {@link gl:getActiveAttrib/3} . If an error occurred, the return
+%% parameters  `Length' ,  `Size' ,  `Type'  and  `Name'  will be unmodified.
+%% This command will return as much information about the varying variables as possible.
+%% If no information is available,  `Length'  will be set to zero and  `Name'  will
+%% be an empty string. This situation could arise if ``gl:getTransformFeedbackVarying''

+%% @doc Start conditional rendering

+%%  Conditional rendering is started using ``gl:beginConditionalRender'' and ended using ``gl:endConditionalRender''
+%% . During conditional rendering, all vertex array commands, as well as  {@link gl:clear/1} 
+%% and  {@link gl:clearBufferiv/3}  have no effect if the (`?GL_SAMPLES_PASSED') result of
+%% the query object  `Id'  is zero, or if the (`?GL_ANY_SAMPLES_PASSED') result is `?GL_FALSE'
+%% . The results of commands setting the current vertex state, such as  {@link gl:vertexAttrib1d/2} 
+%%  are undefined. If the (`?GL_SAMPLES_PASSED') result is non-zero or if the (`?GL_ANY_SAMPLES_PASSED'
+%% ) result is `?GL_TRUE', such commands are not discarded. The  `Id'  parameter to ``gl:beginConditionalRender''
+%%  must be the name of a query object previously returned from a call to  {@link gl:genQueries/1} 
+%% .  `Mode'  specifies how the results of the query object are to be interpreted. If  `Mode' 
+%%  is `?GL_QUERY_WAIT', the GL waits for the results of the query to be available and
+%% then uses the results to determine if subsequent rendering commands are discarded. If  `Mode' 
+%%  is `?GL_QUERY_NO_WAIT', the GL may choose to unconditionally execute the subsequent
+%% rendering commands without waiting for the query to complete. 
+%%
+%%  If  `Mode'  is `?GL_QUERY_BY_REGION_WAIT', the GL will also wait for occlusion
+%% query results and discard rendering commands if the result of the occlusion query is zero.
+%% If the query result is non-zero, subsequent rendering commands are executed, but the GL
+%% may discard the results of the commands for any region of the framebuffer that did not
+%% contribute to the sample count in the specified occlusion query. Any such discarding is
+%% done in an implementation-dependent manner, but the rendering command results may not
+%% be discarded for any samples that contributed to the occlusion query sample count. If  `Mode' 
+%%  is `?GL_QUERY_BY_REGION_NO_WAIT', the GL operates as in `?GL_QUERY_BY_REGION_WAIT'
+%% , but may choose to unconditionally execute the subsequent rendering commands without

+%% ``gl:minSampleShading'' specifies the rate at which samples are shaded within a covered
+%% pixel. Sample-rate shading is enabled by calling  {@link gl:enable/1}  with the parameter `?GL_SAMPLE_SHADING'
+%% . If `?GL_MULTISAMPLE' or `?GL_SAMPLE_SHADING' is disabled, sample shading has
+%% no effect. Otherwise, an implementation must provide at least as many unique color values
+%% for each covered fragment as specified by  `Value'  times  `Samples'  where  `Samples' 
+%%  is the value of `?GL_SAMPLES' for the current framebuffer. At least 1 sample for
+%% each covered fragment is generated. 
+%%
+%%  A  `Value'  of 1.0 indicates that each sample in the framebuffer should be indpendently
+%% shaded. A  `Value'  of 0.0 effectively allows the GL to ignore sample rate shading.
+%% Any value between 0.0 and 1.0 allows the GL to shade only a subset of the total samples
+%% within each covered fragment. Which samples are shaded and the algorithm used to select
+%% that subset of the fragment's samples is implementation dependent.

+%%

+%% due to these limits, the scaling and offset applied to pixels being transferred is performed
+%% as though no such limits were present. 
+%%
+%%  If the sizes of the source and destination rectangles are not equal,  `Filter'  specifies
+%% the interpolation method that will be applied to resize the source image , and must be `?GL_NEAREST'

+%% . The following symbols are accepted in  `Pname' : 
+%%
+%% `?GL_TEXTURE_MIN_FILTER':  The texture minifying function is used whenever the pixel
+%% being textured maps to an area greater than one texture element. There are six defined
+%% minifying functions. Two of them use the nearest one or nearest four texture elements
+%% to compute the texture value. The other four use mipmaps. 
+%%
+%%  A mipmap is an ordered set of arrays representing the same image at progressively lower
+%% resolutions. If the texture has dimensions   2 n*2 m, there are  max(n m)+1 mipmaps. The first
+%% mipmap is the original texture, with dimensions   2 n*2 m. Each subsequent mipmap has
+%% dimensions   2(k-1)*2(l-1), where   2 k*2 l are the dimensions of the previous mipmap, until either
+%%   k= 0 or   l= 0. At that point, subsequent mipmaps have dimension   1*2(l-1) or   2(k-1)*1 until
+%% the final mipmap, which has dimension   1*1. To define the mipmaps, call  {@link gl:texImage1D/8} 
+%% ,  {@link gl:texImage2D/9} ,  {@link gl:texImage3D/10} ,  {@link gl:copyTexImage1D/7} , or  {@link gl:copyTexImage2D/8} 
+%%  with the `level' argument indicating the order of the mipmaps. Level 0 is the original
+%% texture; level   max(n m) is the final   1*1 mipmap. 
+%%
+%%  `Params'  supplies a function for minifying the texture as one of the following: 
+%%
+%% `?GL_NEAREST':  Returns the value of the texture element that is nearest (in Manhattan
+%% distance) to the center of the pixel being textured. 
+%%
+%% `?GL_LINEAR':  Returns the weighted average of the four texture elements that are
+%% closest to the center of the pixel being textured. These can include border texture elements,
+%% depending on the values of `?GL_TEXTURE_WRAP_S' and `?GL_TEXTURE_WRAP_T', and
+%% on the exact mapping. 
+%%
+%% `?GL_NEAREST_MIPMAP_NEAREST':  Chooses the mipmap that most closely matches the size
+%% of the pixel being textured and uses the `?GL_NEAREST' criterion (the texture element
+%% nearest to the center of the pixel) to produce a texture value. 
+%%
+%% `?GL_LINEAR_MIPMAP_NEAREST':  Chooses the mipmap that most closely matches the size
+%% of the pixel being textured and uses the `?GL_LINEAR' criterion (a weighted average
+%% of the four texture elements that are closest to the center of the pixel) to produce a
+%% texture value. 
+%%
+%% `?GL_NEAREST_MIPMAP_LINEAR':  Chooses the two mipmaps that most closely match the
+%% size of the pixel being textured and uses the `?GL_NEAREST' criterion (the texture
+%% element nearest to the center of the pixel) to produce a texture value from each mipmap.
+%% The final texture value is a weighted average of those two values. 
+%%
+%% `?GL_LINEAR_MIPMAP_LINEAR':  Chooses the two mipmaps that most closely match the
+%% size of the pixel being textured and uses the `?GL_LINEAR' criterion (a weighted
+%% average of the four texture elements that are closest to the center of the pixel) to produce
+%% a texture value from each mipmap. The final texture value is a weighted average of those
+%% two values. 
+%%
+%%  As more texture elements are sampled in the minification process, fewer aliasing artifacts
+%% will be apparent. While the `?GL_NEAREST' and `?GL_LINEAR' minification functions
+%% can be faster than the other four, they sample only one or four texture elements to determine
+%% the texture value of the pixel being rendered and can produce moire patterns or ragged
+%% transitions. The initial value of `?GL_TEXTURE_MIN_FILTER' is `?GL_NEAREST_MIPMAP_LINEAR'
+%% . 
+%%
+%% `?GL_TEXTURE_MAG_FILTER':  The texture magnification function is used when the pixel
+%% being textured maps to an area less than or equal to one texture element. It sets the
+%% texture magnification function to either `?GL_NEAREST' or `?GL_LINEAR' (see
+%% below). `?GL_NEAREST' is generally faster than `?GL_LINEAR', but it can produce
+%% textured images with sharper edges because the transition between texture elements is
+%% not as smooth. The initial value of `?GL_TEXTURE_MAG_FILTER' is `?GL_LINEAR'. 
+%%
+%% `?GL_NEAREST':  Returns the value of the texture element that is nearest (in Manhattan
+%% distance) to the center of the pixel being textured. 
+%%
+%% `?GL_LINEAR':  Returns the weighted average of the four texture elements that are
+%% closest to the center of the pixel being textured. These can include border texture elements,
+%% depending on the values of `?GL_TEXTURE_WRAP_S' and `?GL_TEXTURE_WRAP_T', and
+%% on the exact mapping. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_MIN_LOD':  Sets the minimum level-of-detail parameter. This floating-point
+%% value limits the selection of highest resolution mipmap (lowest mipmap level). The initial
+%% value is -1000. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_MAX_LOD':  Sets the maximum level-of-detail parameter. This floating-point
+%% value limits the selection of the lowest resolution mipmap (highest mipmap level). The
+%% initial value is 1000. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_WRAP_S':  Sets the wrap parameter for texture coordinate   s to either `?GL_CLAMP_TO_EDGE'
+%% , `?GL_MIRRORED_REPEAT', or `?GL_REPEAT'. `?GL_CLAMP_TO_BORDER' causes
+%% the   s coordinate to be clamped to the range [(-1 2/N) 1+(1 2/N)], where   N is the size of the texture in
+%% the direction of clamping.`?GL_CLAMP_TO_EDGE' causes   s coordinates to be clamped
+%% to the range  [(1 2/N) 1-(1 2/N)], where   N is the size of the texture in the direction of clamping. `?GL_REPEAT'
+%%  causes the integer part of the   s coordinate to be ignored; the GL uses only the fractional
+%% part, thereby creating a repeating pattern. `?GL_MIRRORED_REPEAT' causes the   s
+%% coordinate to be set to the fractional part of the texture coordinate if the integer part
+%% of   s is even; if the integer part of   s is odd, then the   s texture coordinate is
+%% set to   1-frac(s), where   frac(s) represents the fractional part of  s. Initially, `?GL_TEXTURE_WRAP_S'
+%%  is set to `?GL_REPEAT'. 
+%%
+%% 
+%%
+%% `?GL_TEXTURE_WRAP_T':  Sets the wrap parameter for texture coordinate   t to either `?GL_CLAMP_TO_EDGE'
+%% , `?GL_MIRRORED_REPEAT', or `?GL_REPEAT'. See the discussion under `?GL_TEXTURE_WRAP_S'
+%% . Initially, `?GL_TEXTURE_WRAP_T' is set to `?GL_REPEAT'. 
+%%
+%% `?GL_TEXTURE_WRAP_R':  Sets the wrap parameter for texture coordinate   r to either `?GL_CLAMP_TO_EDGE'
+%% , `?GL_MIRRORED_REPEAT', or `?GL_REPEAT'. See the discussion under `?GL_TEXTURE_WRAP_S'
+%% . Initially, `?GL_TEXTURE_WRAP_R' is set to `?GL_REPEAT'. 
+%%
+%% `?GL_TEXTURE_BORDER_COLOR':  The data in  `Params'  specifies four values that
+%% define the border values that should be used for border texels. If a texel is sampled
+%% from the border of the texture, the values of `?GL_TEXTURE_BORDER_COLOR' are interpreted
+%% as an RGBA color to match the texture's internal format and substituted for the non-existent
+%% texel data. If the texture contains depth components, the first component of `?GL_TEXTURE_BORDER_COLOR'
+%%  is interpreted as a depth value. The initial value is (0.0,  0.0,  0.0,  0.0). 
+%%
+%% `?GL_TEXTURE_COMPARE_MODE':  Specifies the texture comparison mode for currently
+%% bound textures. That is, a texture whose internal format is `?GL_DEPTH_COMPONENT_*';
+%% see  {@link gl:texImage2D/9} ) Permissible values are: 
+%%
+%% `?GL_COMPARE_REF_TO_TEXTURE':  Specifies that the interpolated and clamped   r texture

+%% from the currently bound texture. 
+%%
+%% `?GL_TEXTURE_COMPARE_FUNC':  Specifies the comparison operator used when `?GL_TEXTURE_COMPARE_MODE'

--spec programUniform1i(integer(),integer(),integer()) -> ok.
+%% @doc Specify the value of a uniform variable for a specified program object
+%%
+%% ``gl:programUniform'' modifies the value of a uniform variable or a uniform variable
+%% array. The location of the uniform variable to be modified is specified by  `Location' ,
+%% which should be a value returned by  {@link gl:getUniformLocation/2} . ``gl:programUniform''
+%%  operates on the program object specified by  `Program' .
+%%
+%% The commands ``gl:programUniform{1|2|3|4}{f|i|ui}'' are used to change the value of
+%% the uniform variable specified by  `Location'  using the values passed as arguments.
+%% The number specified in the command should match the number of components in the data
+%% type of the specified uniform variable (e.g., `1' for float, int, unsigned int, bool;
+%% `2' for vec2, ivec2, uvec2, bvec2, etc.). The suffix `f' indicates that floating-point
+%% values are being passed; the suffix `i' indicates that integer values are being passed;
+%% the suffix `ui' indicates that unsigned integer values are being passed, and this
+%% type should also match the data type of the specified uniform variable. The `i' variants
+%% of this function should be used to provide values for uniform variables defined as int, ivec2
+%% , ivec3, ivec4, or arrays of these. The `ui' variants of this function should be
+%% used to provide values for uniform variables defined as unsigned int, uvec2, uvec3, uvec4,
+%% or arrays of these. The `f' variants should be used to provide values for uniform
+%% variables of type float, vec2, vec3, vec4, or arrays of these. Either the `i', `ui'
+%%  or `f' variants may be used to provide values for uniform variables of type bool, bvec2
+%% , bvec3, bvec4, or arrays of these. The uniform variable will be set to false if the input
+%% value is 0 or 0.0f, and it will be set to true otherwise.
+%%
+%% All active uniform variables defined in a program object are initialized to 0 when the
+%% program object is linked successfully. They retain the values assigned to them by a call
+%% to ``gl:programUniform'' until the next successful link operation occurs on the program
+%% object, when they are once again initialized to 0.
+%%
+%% The commands ``gl:programUniform{1|2|3|4}{f|i|ui}v'' can be used to modify a single
+%% uniform variable or a uniform variable array. These commands pass a count and a pointer
+%% to the values to be loaded into a uniform variable or a uniform variable array. A count
+%% of 1 should be used if modifying the value of a single uniform variable, and a count of
+%% 1 or greater can be used to modify an entire array or part of an array. When loading `n'
+%%  elements starting at an arbitrary position `m' in a uniform variable array, elements
+%% `m' + `n' - 1 in the array will be replaced with the new values. If  `M'  +  `N' 
+%%  - 1 is larger than the size of the uniform variable array, values for all array elements
+%% beyond the end of the array will be ignored. The number specified in the name of the command
+%% indicates the number of components for each element in  `Value' , and it should match
+%% the number of components in the data type of the specified uniform variable (e.g., `1'
+%%  for float, int, bool; `2' for vec2, ivec2, bvec2, etc.). The data type specified
+%% in the name of the command must match the data type for the specified uniform variable
+%% as described previously for ``gl:programUniform{1|2|3|4}{f|i|ui}''.
+%%
+%% For uniform variable arrays, each element of the array is considered to be of the type
+%% indicated in the name of the command (e.g., ``gl:programUniform3f'' or ``gl:programUniform3fv''
+%%  can be used to load a uniform variable array of type vec3). The number of elements of
+%% the uniform variable array to be modified is specified by  `Count' 
+%%
+%% The commands ``gl:programUniformMatrix{2|3|4|2x3|3x2|2x4|4x2|3x4|4x3}fv''  are used
+%% to modify a matrix or an array of matrices. The numbers in the command name are interpreted
+%% as the dimensionality of the matrix. The number `2' indicates a 2 � 2 matrix (i.e.,
+%% 4 values), the number `3' indicates a 3 � 3 matrix (i.e., 9 values), and the number `4'
+%%  indicates a 4 � 4 matrix (i.e., 16 values). Non-square matrix dimensionality is explicit,
+%% with the first number representing the number of columns and the second number representing
+%% the number of rows. For example,  `2x4' indicates a 2 � 4 matrix with 2 columns and
+%% 4 rows (i.e., 8 values). If  `Transpose'  is `?GL_FALSE', each matrix is assumed
+%% to be supplied in column major order. If  `Transpose'  is `?GL_TRUE', each matrix
+%% is assumed to be supplied in row major order. The  `Count'  argument indicates the
+%% number of matrices to be passed. A count of 1 should be used if modifying the value of
+%% a single matrix, and a count greater than 1 can be used to modify an array of matrices.

+%% @doc Set a specified viewport
+%%
+%% ``gl:viewportIndexedf'' and ``gl:viewportIndexedfv'' specify the parameters for a
+%% single viewport.  `Index'  specifies the index of the viewport to modify.  `Index' 
+%% must be less than the value of `?GL_MAX_VIEWPORTS'. For ``gl:viewportIndexedf'',  `X' 
+%% ,  `Y' ,  `W' , and  `H'  specify the left, bottom, width and height of the viewport
+%% in pixels, respectively. For ``gl:viewportIndexedfv'',  `V'  contains the address
+%% of an array of floating point values specifying the left ( x), bottom ( y), width ( w),
+%% and height ( h) of each viewport, in that order.  x and  y give the location of the viewport's
+%% lower left corner, and  w and  h give the width and height of the viewport, respectively.
+%% The viewport specifies the affine transformation of   x and   y from normalized device
+%% coordinates to window coordinates. Let  (x nd y nd) be normalized device coordinates. Then the window
+%% coordinates  (x w y w) are computed as follows: 
+%%
+%%  x w=(x nd+1) (width/2)+x
+%%
+%%  y w=(y nd+1) (height/2)+y
+%%
+%%  The location of the viewport's bottom left corner, given by ( x,  y) is clamped to be
+%% within the implementaiton-dependent viewport bounds range. The viewport bounds range [
+%% min,  max] can be determined by calling  {@link gl:getBooleanv/1}  with argument `?GL_VIEWPORT_BOUNDS_RANGE'
+%% . Viewport width and height are silently clamped to a range that depends on the implementation.
+%% To query this range, call  {@link gl:getBooleanv/1}  with argument `?GL_MAX_VIEWPORT_DIMS'. 
+%%
+%%  The precision with which the GL interprets the floating point viewport bounds is implementation-dependent
+%% and may be determined by querying the impementation-defined constant `?GL_VIEWPORT_SUBPIXEL_BITS'
+%% . 
+%%
+%%  Calling ``gl:viewportIndexedfv'' is equivalent to calling see `glViewportArray'
+%% with  `First'  set to  `Index' ,  `Count'  set to 1 and  `V'  passsed directly.
+%% ``gl:viewportIndexedf'' is equivalent to:  void glViewportIndexedf(GLuint index, GLfloat
+%% x, GLfloat y, GLfloat w, GLfloat h) { const float v[4] = { x, y, w, h }; glViewportArrayv(index,

+%% @doc Defines a barrier ordering memory transactions
+%%
+%% ``gl:memoryBarrier'' defines a barrier ordering the memory transactions issued prior
+%% to the command relative to those issued after the barrier. For the purposes of this ordering,
+%% memory transactions performed by shaders are considered to be issued by the rendering
+%% command that triggered the execution of the shader.  `Barriers'  is a bitfield indicating
+%% the set of operations that are synchronized with shader stores; the bits used in  `Barriers' 
+%%  are as follows: 
+%%
+%% 
+%%
+%% `?GL_VERTEX_ATTRIB_ARRAY_BARRIER_BIT':  If set, vertex data sourced from buffer objects
+%% after the barrier will reflect data written by shaders prior to the barrier. The set of
+%% buffer objects affected by this bit is derived from the buffer object bindings used for
+%% generic vertex attributes derived from the `?GL_VERTEX_ATTRIB_ARRAY_BUFFER' bindings.
+%% 
+%%
+%% `?GL_ELEMENT_ARRAY_BARRIER_BIT':  If set, vertex array indices sourced from buffer
+%% objects after the barrier will reflect data written by shaders prior to the barrier. The
+%% buffer objects affected by this bit are derived from the `?GL_ELEMENT_ARRAY_BUFFER'
+%% binding. 
+%%
+%% `?GL_UNIFORM_BARRIER_BIT':  Shader uniforms sourced from buffer objects after the
+%% barrier will reflect data written by shaders prior to the barrier. 
+%%
+%% `?GL_TEXTURE_FETCH_BARRIER_BIT':  Texture fetches from shaders, including fetches
+%% from buffer object memory via buffer textures, after the barrier will reflect data written
+%% by shaders prior to the barrier. 
+%%
+%% `?GL_SHADER_IMAGE_ACCESS_BARRIER_BIT':  Memory accesses using shader image load,
+%% store, and atomic built-in functions issued after the barrier will reflect data written
+%% by shaders prior to the barrier. Additionally, image stores and atomics issued after the
+%% barrier will not execute until all memory accesses (e.g., loads, stores, texture fetches,
+%% vertex fetches) initiated prior to the barrier complete. 
+%%
+%% `?GL_COMMAND_BARRIER_BIT':  Command data sourced from buffer objects by Draw*Indirect
+%% commands after the barrier will reflect data written by shaders prior to the barrier.
+%% The buffer objects affected by this bit are derived from the `?GL_DRAW_INDIRECT_BUFFER'
+%%  binding. 
+%%
+%% `?GL_PIXEL_BUFFER_BARRIER_BIT':  Reads and writes of buffer objects via the `?GL_PIXEL_PACK_BUFFER'
+%%  and `?GL_PIXEL_UNPACK_BUFFER' bindings (via  {@link gl:readPixels/7} ,  {@link gl:texSubImage1D/7} 
+%% , etc.) after the barrier will reflect data written by shaders prior to the barrier. Additionally,
+%% buffer object writes issued after the barrier will wait on the completion of all shader
+%% writes initiated prior to the barrier. 
+%%
+%% `?GL_TEXTURE_UPDATE_BARRIER_BIT':  Writes to a texture via ``gl:tex(Sub)Image*'', ``gl:copyTex(Sub)Image*''
+%% , ``gl:compressedTex(Sub)Image*'', and reads via  {@link gl:getTexImage/5}  after the barrier
+%% will reflect data written by shaders prior to the barrier. Additionally, texture writes
+%% from these commands issued after the barrier will not execute until all shader writes
+%% initiated prior to the barrier complete. 
+%%
+%% `?GL_BUFFER_UPDATE_BARRIER_BIT':  Reads or writes via  {@link gl:bufferSubData/4} ,  {@link gl:copyBufferSubData/5} 
+%% , or  {@link gl:getBufferSubData/4} , or to buffer object memory mapped by see `glMapBuffer'
+%%  or see `glMapBufferRange' after the barrier will reflect data written by shaders
+%% prior to the barrier. Additionally, writes via these commands issued after the barrier
+%% will wait on the completion of any shader writes to the same memory initiated prior to
+%% the barrier. 
+%%
+%% `?GL_FRAMEBUFFER_BARRIER_BIT':  Reads and writes via framebuffer object attachments
+%% after the barrier will reflect data written by shaders prior to the barrier. Additionally,
+%% framebuffer writes issued after the barrier will wait on the completion of all shader
+%% writes issued prior to the barrier. 
+%%
+%% `?GL_TRANSFORM_FEEDBACK_BARRIER_BIT':  Writes via transform feedback bindings after
+%% the barrier will reflect data written by shaders prior to the barrier. Additionally, transform
+%% feedback writes issued after the barrier will wait on the completion of all shader writes
+%% issued prior to the barrier. 
+%%
+%% `?GL_ATOMIC_COUNTER_BARRIER_BIT':  Accesses to atomic counters after the barrier
+%% will reflect writes prior to the barrier. 
+%%
+%%  If  `Barriers'  is `?GL_ALL_BARRIER_BITS', shader memory accesses will be synchronized
+%% relative to all the operations described above. 
+%%
+%%  Implementations may cache buffer object and texture image memory that could be written
+%% by shaders in multiple caches; for example, there may be separate caches for texture,
+%% vertex fetching, and one or more caches for shader memory accesses. Implementations are
+%% not required to keep these caches coherent with shader memory writes. Stores issued by
+%% one invocation may not be immediately observable by other pipeline stages or other shader
+%% invocations because the value stored may remain in a cache local to the processor executing
+%% the store, or because data overwritten by the store is still in a cache elsewhere in the
+%% system. When ``gl:memoryBarrier'' is called, the GL flushes and/or invalidates any caches
+%% relevant to the operations specified by the  `Barriers'  parameter to ensure consistent
+%% ordering of operations across the barrier. 
+%%
+%%  To allow for independent shader invocations to communicate by reads and writes to a common
+%% memory address, image variables in the OpenGL Shading Language may be declared as "coherent".
+%% Buffer object or texture image memory accessed through such variables may be cached only
+%% if caches are automatically updated due to stores issued by any other shader invocation.
+%% If the same address is accessed using both coherent and non-coherent variables, the accesses
+%% using variables declared as coherent will observe the results stored using coherent variables
+%% in other invocations. Using variables declared as "coherent" guarantees only that the
+%% results of stores will be immediately visible to shader invocations using similarly-declared
+%% variables; calling ``gl:memoryBarrier'' is required to ensure that the stores are visible
+%% to other operations. 
+%%
+%%  The following guidelines may be helpful in choosing when to use coherent memory accesses
+%% and when to use barriers. 
+%%
+%% Data that are read-only or constant may be accessed without using coherent variables or
+%% calling MemoryBarrier(). Updates to the read-only data via API calls such as BufferSubData
+%% will invalidate shader caches implicitly as required.
+%%
+%% Data that are shared between shader invocations at a fine granularity (e.g., written by
+%% one invocation, consumed by another invocation) should use coherent variables to read
+%% and write the shared data.
+%%
+%% Data written by one shader invocation and consumed by other shader invocations launched
+%% as a result of its execution ("dependent invocations") should use coherent variables in
+%% the producing shader invocation and call memoryBarrier() after the last write. The consuming
+%% shader invocation should also use coherent variables.
+%%
+%% Data written to image variables in one rendering pass and read by the shader in a later
+%% pass need not use coherent variables or memoryBarrier(). Calling MemoryBarrier() with
+%% the SHADER_IMAGE_ACCESS_BARRIER_BIT set in  `Barriers'  between passes is necessary.
+%%
+%% Data written by the shader in one rendering pass and read by another mechanism (e.g.,
+%% vertex or index buffer pulling) in a later pass need not use coherent variables or memoryBarrier().
+%% Calling ``gl:memoryBarrier'' with the appropriate bits set in  `Barriers'  between
+%% passes is necessary.

+%%
+%% ``glu:sphere'' draws a sphere of the given radius centered around the origin. The sphere
+%% is subdivided around the `z' axis into slices and along the  `z' axis  into
+%% stacks (similar to lines of longitude and latitude). 
+%%
+%%  If the orientation is set to `?GLU_OUTSIDE'  (with  {@link glu:quadricOrientation/2} ),
+%% then any normals generated  point away from the center of the sphere. Otherwise, they
+%% point toward the center of the sphere. 
+%%
+%%  If texturing is turned on (with  {@link glu:quadricTexture/2} ), then texture  coordinates
+%% are  generated so that `t' ranges from 0.0 at   z=-radius to 1.0 at   z= radius (`t'
+%%  increases linearly along longitudinal lines), and `s' ranges from 0.0 at the +`y'
+%%  axis, to 0.25 at the  +`x' axis,  to 0.5 at the -`y' axis, to 0.75 at the -`x'
+%%  axis, and back to 1.0  at the +`y' axis.
