However, reading back the OpenGL matrix as part of your
rendering process isn't really a good thing to do, since
it requires waiting for any pipelined OpenGL commands
that you've sent to complete. This can slow things down
considerably.

If you're doing this a lot, it may be better to keep
track of the transformations yourself.
