i would suggest to redo the very nice ol’ “the opengl machine” state machine diagram. (it was last done for opengl 1.1 actually…)
i know that would get somehow complicated today 
but i think sgi should do or the arb… if not, maybe some of us should do?
(Would be fun to work through ALL the specs but maybe some real insider pro could do?)
yeah i would really like to fill my wall with that …
