patch to fix byte vs pixel issue in 3d texture offset calculation

Does this patch fix it? This is something I've ported from another (closed) driver, though I already thought that other chips might be affected too... i915 should suffer from the same issue, but apparently it can't run this testcase.

Fix pushed.  Thanks!

Mass version move, cvs -> git
