Subject: fix r128 rendering, lockups
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=25f21b5331d27225b1f6b7aaf2c9bf3f32764d91;p=mesa.git

fix r128 rendering, lockups

mis-count in offset led to mis-rendering and lockups;
units are 4 bytes rather than 1.  Noticed by Chris Salch.
fixes bug 7994, possibly others.
