Merge commit 'origin/gallium-master-merge'
This is the big merge of the gallium-0.2 branch into master. gallium-master-merge was just the staging area for it. Both gallium-0.2 and gallium-master-merge are considered closed now. Conflicts: progs/demos/Makefile src/mesa/main/state.c src/mesa/main/texenvprogram.c
