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.
