'''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.
The official definition of this extension is available here:
