'''OpenGL extension EXT.fog_coord
Overview (from the spec)
This extension allows specifying an explicit per-vertex fog
coordinate to be used in fog computations, rather than using a
fragment depth-based fog equation.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/EXT/fog_coord.txt
