Add GL_EXT_ES1_compatibility
I am using OpenGL ES 1.1 code with the OpenGL implementation of Mesa. But the declaration of 4 prototypes are missing for compatibility. So I just define GL_EXT_ES1_compatibility to add these prototypes. A change request for this compatibility extension is open in the OpenGL-Registry repository of the Khronos Group: https://github.com/KhronosGroup/OpenGL-Registry/pull/451 Note that this change request is not yet complete, the textual specification is missing.
