  1. '''OpenGL extension ATI.separate_stencil
  2.  
  3. Overview (from the spec)
  4.     
  5.     This extension provides the ability to modify the stencil buffer
  6.     differently based on the facing direction of the primitive that
  7.     generated the fragment.
  8.  
  9. The official definition of this extension is available here:
  10.     http://oss.sgi.com/projects/ogl-sample/registry/ATI/separate_stencil.txt
