@sulu - yeah, i've noticed all opengl functions are in files from one directory, and these files are referenced by other files only few times... they look quite simple, there are only simple poligons/lines, textures and some viewport matrix simple operations (these can be tricky, but even if something is not supported, it doesn't mean it could not be rewritten with little effort )

@Aapo - thanks for your reply, one last question - did you publish your patches somewhere? (i mean, the first 4 of them are in the first post, but are other modifications also published as patches somewhere?)

it looks like I have what to do with my free time during next weekend
