        Add initial 'cogl' implementation. 'cogl' is a simple abstration
        layer over GL and GL/ES used by clutter internally. It should
        eventually allow clutter applications to be run on both GL and GL/ES
        with just a recompile as well as provide more debugging and potentially
        profiling information for GL and GL/ES usage.

        This commit contains the initial GL implementation.
