'''OpenGL extension NV.fragment_program_option
This module customises the behaviour of the
OpenGL.raw.GL.NV.fragment_program_option to provide a more
Python-friendly API
Overview (from the spec)
This extension provides additional fragment program functionality
to extend the standard ARB_fragment_program language and execution
environment. ARB programs wishing to use this added functionality
need only add:
OPTION NV_fragment_program;
to the beginning of their fragment programs.
The functionality provided by this extension, which is roughly
equivalent to that provided by the NV_fragment_program extension,
includes:
* increased control over precision in arithmetic computations and
storage,
* data-dependent conditional writemasks,
* an absolute value operator on scalar and swizzled operand loads,
* instructions to compute partial derivatives, and perform texture
lookups using specified partial derivatives,
* fully orthogonal "set on" instructions,
* instructions to compute reflection vector and perform a 2D
coordinate transform, and
* instructions to pack and unpack multiple quantities into a single
component.
The official definition of this extension is available here:
