'''OpenGL extension EXT.unpack_subimage
This module customises the behaviour of the
OpenGL.raw.GLES2.EXT.unpack_subimage to provide a more
Python-friendly API
Overview (from the spec)
This OpenGL ES 2.0 extension adds support for GL_UNPACK_ROW_LENGTH,
GL_UNPACK_SKIP_ROWS and GL_UNPACK_SKIP_PIXELS as valid enums to
PixelStore. The functionality is the same as in OpenGL. These are
useful for updating textures with a sub-rectangle of pixel data
coming from a larger image in host memory.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/unpack_subimage.txt
