[Mesa-dev] [RFC] st/mesa + r600g ARB_multisample_texture initial pass

[Dave Airlie]

Hey,

just posting this for others to take a look, its the state tracker
pieces to enable ARB_texture_multisample on gallium drivers, Marek
has done most of the internal gallium work for this already.

The state tracker pieces are hopefully close to complete, however
the r600g patch probably needs some work, the get_sample_position
is hopelessly naive, and it isn't passing all the tests yet,

The only problem with pushing it, is I guess drivers that don't
do get_sample_position but advertise the gallium CAP already,
might fallover.

Dave.
