- '''OpenGL extension SGIS.fog_function
-
- Overview (from the spec)
-
- This extension allows to define application-specific fog blend-factor
- function. Function is defined by the set of the "control" points and
- should be monotonic. Each control point represented as a pair of the
- eye-space distance value and corresponding value of the fog blending
- factor. The minimum number of control points is one. The maximum
- number is implementation dependent.
-
-
- The official definition of this extension is available here:
- http://oss.sgi.com/projects/ogl-sample/registry/SGIS/fog_function.txt
