'''OpenGL extension IMG.texture_compression_pvrtc
This module customises the behaviour of the
OpenGL.raw.GLES2.IMG.texture_compression_pvrtc to provide a more
Python-friendly API
Overview (from the spec)
This extension provides additional texture compression functionality
specific to Imagination Technologies PowerVR Texture compression format
(called PVRTC) subject to all the requirements and limitations described
by the OpenGL 1.3 specifications.
This extension supports 4 and 2 bit per pixel texture compression
formats. Because the compression of PVRTC is very CPU intensive,
it is not appropriate to carry out compression on the target
platform. Therefore this extension only supports the loading of
compressed texture data.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/IMG/texture_compression_pvrtc.txt
