Looking at this a little more, I think the existing block of these enums
should be removed (except MAX_GEOMETRY_IMAGE_UNIFORMS), and this block
should be added to the existing "["GL", "GL_CORE", "GLES3"]" block.

It looks like the rest of the patches in this series have a similar
issue.  Patch 3 also has the geometry shader issue.
