No RGB non-RGBA formats exposed for EGLConfigs. #764

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
All R8G8B8 configs have A8 in EGLConfigs.
This makes it impossible to get an RGBX PBuffer.

In Firefox, I suppose we'll work around this with colorMask(1,1,1,0) instead, 
but this seems more prone to performance issues.

Hey jdashg,

D3D11 doesn't have an R8G8B8 format, see:

Can you explain the use case? That'll help understand what we would implement 
in D3D11.
