[Piglit] [PATCH v2 0/4] Stress an i965 blitter path

This series modifies getteximage-simple to work on a texture of maximum
width. This enables us to test an existing fallback path for i965 which
changes the texture's tiling to linear. It also enables us to test an
alternative fallback path [1] which keeps the texture's tiling.

This works on all GEN hardware, but on gen4 we run into the floating
point texture values being a tad off. This isn't a new problem as that
platform also fails another floating point teximage test. This test
passes on gen4 if I change the texture to be an integer format. We lose
the interesting pattern if I do so, however. I don't mind changing the
format if people prefer.
