OpenGL extension NV.fragment_program2
 
This module customises the behaviour of the 
OpenGL.raw.GL.NV.fragment_program2 to provide a more 
Python-friendly API
 
Overview (from the spec)
        
        This extension, like the NV_fragment_program_option 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_program2;
        
        to the beginning of their fragment programs.
        
        New functionality provided by this extension, above and beyond that
        already provided by the NV_fragment_program_option extension, includes:
        
        
          * structured branching support, including data-dependent IF tests, loops
            supporting a fixed number of iterations, and a data-dependent loop
            exit instruction (BRK),
        
          * subroutine calls,
        
          * instructions to perform vector normalization, divide vector components
            by a scalar, and perform two-component dot products (with or without a
            scalar add),
        
          * an instruction to perform a texture lookup with an explicit LOD,
        
          * a loop index register for indirect access into the texture coordinate
            attribute array, and
        
          * a facing attribute that indicates whether the fragment is generated
            from a front- or back-facing primitive.
