Description Frank Richter 2006-08-10 16:22:07 UTC 
Write masks specified for the TEX ARB_fragment_program instructions are ignored,
programs using that feature produce incorrect output.

Apparently the i915 TEXLD does not honor write masks. Work around that by
sampling to a temporary register and MOVing from that to the actual destination
with the correct writemask.

Fixed. Closing.

Mass version move, cvs -> git
