'''OpenGL extension INGR.color_clamp
Overview (from the spec)
Various RGBA color space conversions require clamping to values
in a more constrained range than [0, 1]. This extension allows
the definition of independent color clamp values for each of the
four color components as part of the Final Conversion in the pixel
transfer path for draws, reads, and copies.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/INGR/color_clamp.txt
