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.

Patch to make i915 driver support writemasks for tex instructions

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
