[Mesa-dev] ARB_vertex_type_2_10_10_10_rev support

[Dave Airlie]

These 4 patches are the initial core mesa support for the extensions with
the long name. After these patches we need to regenerate the gl api.

This series adds all the APIs and device driver interface changes,
I've only really tested it all on softpipe so far, with some r600g testing.

I have the state tracker patches also to send out later.

Dave.
