[Piglit] [PATCH 0/3] arb_gpu_shader5: add test for textureGatherOffset

[Nicolai Hähnle]

Hi,

the point of this is to test more than just compiling textureGatherOffset.
Having a texture that is more than just a checkerboard is kind of important
for that, hence the first two patches. The new test currently fails in
st/glsl_to_tgsi.

Cheers,
Nicolai
