After discussing this at length on IRC with another coder, we think that the
easiest solution would be to have one GL context per thread (and multiple
contexts can share the same rendering target and also texture handles).
If we add 'intelligent' (i.e. 'lazy' or 'just in time' :-) ) state change
evaluation it could even be pretty efficient code-wise (maybe not so
efficient in the GL driver though as it may lead to more 'pipeline flushes'
than the 'hacky' solution).
After we just have to rely that this is properly implemented at the GL
I once wanted to toy with this in the DDraw code base but well, seeing that
it will phased out pretty soon I did not do any work on it. On the other
hand I could try for some specific games (like DungeonSiege) as an
experiment to then port it over to WineD3D.
