Subject: meta: Fix blit shader compile on non-glsl-130 drivers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b3dcce65c9b400e8d658f672130c617d8ac84cc9;p=mesa.git

meta: Fix blit shader compile on non-glsl-130 drivers.

Compare this VS to the one for the post-130 case.  Fixes piglit
glsl-lod-bias, and presumably tons of other code (I haven't done a full
piglit run on swrast).
