OPENGL: Merged from trunk, from rev 52105 to 53396.
This includes an rather hacky attempt to merge all the recent gp2x backend changes into the branch. I suppose the gp2x backend and probably all new backends, i.e. gph, dingux etc., might not compile anymore. Since I have no way of testing those it would be nice if porters could look into getting those up to speed in this branch. svn-id: r53399
