'''OpenGL extension EXT.gpu_program_parameters
This module customises the behaviour of the
OpenGL.raw.GL.EXT.gpu_program_parameters to provide a more
Python-friendly API
Overview (from the spec)
This extension provides a new set of procedures to load multiple
consecutive program environment parameters more efficiently, via a single
GL call instead of multiple calls. This will reduce the amount of CPU
overhead involved in loading parameters.
With the existing ARB_vertex_program and ARB_fragment_program APIs,
program parameters must be loaded one at a time, via separate calls.
While the NV_vertex_program extension provides a set of similar functions
that can be used to load program environment parameters (which are
equivalent to "program parameters" in NV_vertex_program), no such function
exists for program local parameters.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/gpu_program_parameters.txt
