'''OpenGL extension ARB.draw_buffers
Overview (from the spec)
This extension extends ARB_fragment_program and ARB_fragment_shader
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/ARB/draw_buffers.txt
