'''OpenGL extension EXT.index_func
This module customises the behaviour of the
OpenGL.raw.GL.EXT.index_func to provide a more
Python-friendly API
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://www.opengl.org/registry/specs/EXT/index_func.txt
