'''OpenGL extension EXT.subtexture
This module customises the behaviour of the
OpenGL.raw.GL.EXT.subtexture to provide a more
Python-friendly API
Overview (from the spec)
This extension allows a contiguous portion of an already-existing
texture image to be redefined, without affecting the remaining portion
of the image, or any of the other state that describe the texture. No
provision is made to query a subregion of a texture.
Semantics for null image pointers are defined for TexImage1D,
TexImage2D, and TexImage3DEXT. Null image pointers can be used by
applications to effectively support texture arrays whose dimensions
are not a power of 2.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/subtexture.txt
