'''OpenGL extension NV.parameter_buffer_object

This module customises the behaviour of the 
OpenGL.raw.GL.NV.parameter_buffer_object to provide a more 
Python-friendly API

Overview (from the spec)
	
	This extension, in conjunction with NV_gpu_program4, provides a new type
	of program parameter than can be used as a constant during vertex,
	fragment, or geometry program execution.  Each program target has a set of
	parameter buffer binding points to which buffer objects can be attached.
	
	A vertex, fragment, or geometry program can read data from the attached
	buffer objects using a binding of the form "program.buffer[a][b]".  This
	binding reads data from the buffer object attached to binding point <a>.
	The buffer object attached is treated either as an array of 32-bit words
	or an array of four-component vectors, and the binding above reads the
	array element numbered <b>.
	
	The use of buffer objects allows applications to change large blocks of
	program parameters at once, simply by binding a new buffer object.  It
	also provides a number of new ways to load parameter values, including
	readback from the frame buffer (EXT_pixel_buffer_object), transform
	feedback (NV_transform_feedback), buffer object loading functions such as
	MapBuffer and BufferData, as well as dedicated parameter buffer update
	functions provided by this extension.
