'''OpenGL extension EXT.draw_instanced
This module customises the behaviour of the
OpenGL.raw.GL.EXT.draw_instanced to provide a more
Python-friendly API
Overview (from the spec)
This extension provides the means to render multiple instances of
an object with a single draw call, and an "instance ID" variable
which can be used by the vertex program to compute per-instance
values, typically an object's transform.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/draw_instanced.txt
