From: Dave Airlie <airl...@redhat.com>
For 1D and 2D arrays we don't want the other coordinates being
offset and affecting where we sample. I wrote this patch 6 months
ago but lost it.
This fixes at least
./bin/tex-miplevel-selection textureOffset 1DArray
./bin/tex-miplevel-selection textureOffset 2DArray
