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

Overview (from the spec)
        
        This extension defines an interface that allows improved control
        of the physical memory used by the graphics device.
        
        It allows an existing page of system memory allocated by the application
        to be used as memory directly accessible to the graphics processor. One
        example application of this functionality would be to be able to avoid an
        explicit synchronous copy with sub-system of the application; for instance
        it is possible to directly draw from a system memory copy of a video
        image.

The official definition of this extension is available here:
