[Mesa-dev] [RFT PATCH 1/2] nouveau: fix GL_CLAMP

[Ilia Mirkin]

My earlier observations were that this didn't actually do anything
useful on nv10. however it seems to help with nv25-on-nv30. should try
to test it on "real" hw.

Note - this needs to be redone so as to avoid returning 0x5 on hw that
doesn't support it. According to rnndb, it doesn't exist on NV4/NV5.

However the immediate desire is to double-check that it doesn't break
anything on pre-NV20 hw.
