<p>
Fix message handling in select requests</p>
<p>
percept_db used to send results in untagged messages, and
use a non selective receive to extract them. When percept
is used from the shell process, this can confuse other
messages with the actual result.</p>
<p>
Add a tag to the message to be {result, Result}. Add
demonitor to avoid keeping DOWN message in the queue fix
one spec in do_start/0</p>

<p>
Fix egd_render transparent to use float constants.</p>

The render engine has float guards to enhance beam code
generation. However, the default case used integers which
caused the engine to crash. This is now fixed.</p>

<item>
<p>The documentation is now possible to build in an open
source environment after a number of bugs are fixed and
some features are added in the documentation build
process. </p>
<p>- The arity calculation is updated.</p>
<p>- The module prefix used in the function names for
bif's are removed in the generated links so the links
will look like
"http://www.erlang.org/doc/man/erlang.html#append_element-2"
instead of
"http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".</p>
<p>- Enhanced the menu positioning in the html
documentation when a new page is loaded.</p>
<p>- A number of corrections in the generation of man
pages (thanks to Sergei Golovan)</p>
<p>- The legal notice is taken from the xml book file so
OTP's build process can be used for non OTP
applications.</p>
