Merge branch 'egil/egd_render' into ccase/r13b04_dev
* egil/egd_render: Fix egd_render transparent to use float constants OTP-8425 Fix egd_render transparent to use float constants. 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.
