I have to correct myself.  I've got a set of shaders that work on
nvidia and the tip of mesa_7_7_branch, but fail with the tip of
7.8.  It's error 0x501 (invalid value, IIRC?) and comes from uniform
handling, I think in glGetActiveUniform.

I need to run right now but hope to do more investigation today.  In
the attached shaders, I get the error with 'texDepth', for example.
