  1. '''OpenGL extension ATI.fragment_shader
  2.  
  3. Overview (from the spec)
  4.     
  5.     This extension exposes a powerful fragment shading model which
  6.     provides a very general means of expressing fragment color blending
  7.     and dependent texture address modification.  The programming is
  8.     a register-based model in which there is a fixed number of 
  9.     instructions, texture lookups, read/write registers, and constants.
  10.     
  11.     The fragment shader extension provides a unified instruction set
  12.     for operating on address or color data and eliminates the 
  13.     distinction between the two.  This extension provides all the 
  14.     interfaces necessary to fully expose this programmable fragment 
  15.     shader in GL.
  16.     
  17.     Although conceived as a device-independent extension which would 
  18.     expose the capabilities of future generations of hardware, changing 
  19.     trends in programmable hardware have affected the lifespan of this 
  20.     extension.  For this reason you will now find a fixed set of 
  21.     features and resources exposed, and the queries to determine this 
  22.     set have been deprecated.
  23.  
  24. The official definition of this extension is available here:
  25.     http://oss.sgi.com/projects/ogl-sample/registry/ATI/fragment_shader.txt
