'''OpenGL extension ARB.texture_buffer_range
This module customises the behaviour of the
OpenGL.raw.GL.ARB.texture_buffer_range to provide a more
Python-friendly API
Overview (from the spec)
ARB_texture_buffer_object (which was promoted to core in OpenGL 3.1)
introduced the ability to attach the data store of a buffer object
to a buffer texture and access it from shaders. The extension only allows
the entire store of the buffer object to the texture. This extension
expands on this and allows a sub-range of the buffer's data store to
be attached to a texture. This can be used, for example, to allow multiple
buffer textures to be backed by independent sub-ranges of the same buffer
object, or for different sub-ranges of a single buffer object to be used
for different purposes.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/ARB/texture_buffer_range.txt
