'''OpenGL extension ATI.draw_buffers
Overview (from the spec)
This extension extends ARB_fragment_program to allow multiple output
colors, and provides a mechanism for directing those outputs to
multiple color buffers.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/ATI/draw_buffers.txt
