r300g_multitexturing_v2.diff

Yes, your calculations are OK. The problem is the
if (&state->sampler_views[i]->base != views[i]) {}
part, which leaves some samplers untouched, and their cache regions get reused
sometimes.

My attached patch is IMHO significantly better than the previous one. It
completely fixes texturing in etqw, but there are occasional glitches in ut2004
and the water in googleearth is still bad. See the TODO and XXX comments in the
patch for more explanation.
