I dunno... I just never really looked at render too much. As I recall back when it was first everyone wanted to do compositing with it and the general reponse was that it was only for AA text.

Yeah I know. I doubt it'll be that bad. It's just that I've gotten to understand the 2d engine pretty well (or at least I think I do) and the 3D engine seems like this daunting "thing" out there. However looking at the code and databooks it doesn't look that complicated, I just need to sit down and do it some day.

Is there anyway xfree86 could use them for the shape extension? or does it already? Alex __________________________________ Do you Yahoo!?
