  1. '''OpenGL extension ARB.draw_buffers
  2.  
  3. Overview (from the spec)
  4.     
  5.     This extension extends ARB_fragment_program and ARB_fragment_shader
  6.     to allow multiple output colors, and provides a mechanism for
  7.     directing those outputs to multiple color buffers.
  8.

  10. The official definition of this extension is available here:
