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

+ * 1. Vertex fetch/convert - to grab vertex data from incoming vertex
+ * arrays and convert to format needed by vertex shaders.
+ * 2. Vertex store/emit - to convert simple float[][4] vertex attributes
+ * (which is the organization used throughout the draw/prim pipeline) to
+ * hardware-specific formats and emit into hardware vertex buffers.
