'''OpenGL extension SGIS.texture_color_mask
This module customises the behaviour of the
OpenGL.raw.GL.SGIS.texture_color_mask to provide a more
Python-friendly API
Overview (from the spec)
This extension implements the same functionality for texture
updates that glColorMask implements for color buffer updates.
Masks for updating textures with indexed internal formats
(the analog for glIndexMask) should be supported by a separate extension.
The extension allows an application to update a subset of
components in an existing texture. The masks are applied after
all pixel transfer operations have been performed, immediately
prior to writing the texel value into texture memory. They
apply to all texture updates.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/SGIS/texture_color_mask.txt
