Title: Replace direct GL calls with VideoManager wrappers.

Minor cleanup, might allow to get rid of gl matrix stack calls, as they are deprecated.

On the long term it might make more sense to rewrite the code not to require a transform/matrix stack. But that would be a somewhat bigger undertaking.
