'''OpenGL extension NV.texture_compression_s3tc_update
This module customises the behaviour of the
OpenGL.raw.GLES2.NV.texture_compression_s3tc_update to provide a more
Python-friendly API
Overview (from the spec)
This extension allows for full or partial image updates to a
compressed 2D texture from an uncompressed texel data buffer using
TexImage2D and TexSubImage2D. Consquently, if a compressed internal
format is used, all the restrictions associated with compressed
textures will apply. These include sub-image updates aligned to 4x4
pixel blocks and the restriction on usage as render targets.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/texture_compression_s3tc_update.txt
