'''OpenGL extension NV.draw_buffers
This module customises the behaviour of the
OpenGL.raw.GLES2.NV.draw_buffers to provide a more
Python-friendly API
Overview (from the spec)
This extension extends OpenGL ES 2.0 to allow multiple output
colors, and provides a mechanism for directing those outputs to
multiple color buffers.
This extension serves a similar purpose to ARB_draw_buffers except
that this is for OpenGL ES 2.0.
When OpenGL ES 3.0 is present, this extension relaxes the order
restriction on color attachments to draw framebuffer objects.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/draw_buffers.txt
