Example usage here:

http://pyopengl.cvs.sourceforge.net/pyopengl/OpenGLContext/tests/getteximage.py?view=markup

Though note that *normally* you want to keep the image locally rather 
than loading it into the GL and back.  However, if you're doing pixel 
transformations or want to get e.g. mip-mapped versions of it then this 
approach can be useful.
