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

Overview (from the spec)
        
        This extension introduces a new data type for half-precision (16-bit)
        floating-point quantities.  The floating-point format is very similar
        to the IEEE single-precision floating-point standard, except that it
        has only 5 exponent bits and 10 mantissa bits.  Half-precision floats
        are smaller than full precision floats and provide a larger dynamic
        range than similarly sized normalized scalar data types.
        
        This extension allows applications to use half-precision floating-
        point data when specifying pixel data.  It extends the existing image
        specification commands to accept the new data type.
        
        Floating-point data is clamped to [0, 1] at various places in the
        GL unless clamping is disabled with the ARB_color_buffer_float
        extension.

The official definition of this extension is available here:
