- '''OpenGL extension EXT.index_func
-
- Overview (from the spec)
-
- This extension provides a way to discard fragments when a comparison
- between the fragment's index value and a reference index fails. This
- may be used similarly to the alpha test which is available in RGBA mode.
-
- The official definition of this extension is available here:
- http://oss.sgi.com/projects/ogl-sample/registry/EXT/index_func.txt
-
- Automatically generated by the get_gl_extensions script, do not edit!
