'''OpenGL extension EXT.pixel_transform
This module customises the behaviour of the
OpenGL.raw.GL.EXT.pixel_transform to provide a more
Python-friendly API
Overview (from the spec)
This extension provides support for scaling, rotation, translation and
shearing of two-dimensional pixel rectangles in the pixel rasterizer.
The transformation is defined via a 4x4 matrix, where only those entries
which apply as a 2D affine transformation will be accepted and used.
These matrices can be manipulated using the same functions as the other
OpenGL matrix stacks.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/pixel_transform.txt
