(From update of attachment 113577)
GraphicsContext3D and Extensions3D have followed the functionality and naming conventions in OpenGL ES 2.0 and extensions. The most consistent way to handle this would be to have the underlying implementation report support for GL_EXT_texture_format_BGRA8888 when running on desktop GL supporting GL_EXT_bgra. This is how Chromium's command buffer implementation works. See src/gpu/command_buffer/service/feature_info.cc. For this reason I'm marking this r-. If you really want to pursue this direction then minimally you need to update the documentation on Extensions3D.h indicating which extensions it supports.
