Thanks for the review.

I found no compiler warnings with gcc 4, 5, 7 and clang 3.8.
"glsl-1.10-built-in-uniform-state" currently fails on Mesa because the
values of gl_SpotExponent and gl_SpotCosCutoff are swapped (Glean didn't
test those uniforms)
"glsl-1.10-built-in-matrix-state" currently fails on Mesa because
gl_NormalScale is the reciprocal of the desired value (at least for
drivers that use mesa's modelspace-lighting optimization (Glean didn't
test gl_NormalScale).
I have posted patches for both issues to mesa-dev.

The first of those is pretty straightforward, though my commit message
could have been clearer. The second patch could use a Piglit test for
GL_RESCALE_NORMAL with the fixed-function pipeline to make sure it
introduces no regressions...
Otherwise all tests pass.

If it hasn't bee revoked due to inactivity I still should have commit
access to Piglit. I'll try pushing the series at the end of the week and
report back if that fails.
