i really have next to no GEM knowledge, but i was always asking
myself whether GEM compiles the GL commands to display lists.
If yes, is that structured by using separate gemheads, if no, why
isn't it used?
If display lists are used i would think it shouldn't make a lot of
difference which language is used for the GL commands (apart from
changing parameters maybe).
