Very nice, thanks!

I don't quite know what piglit or shader_runner is... I guess it's
stuff here: http://cgit.freedesktop.org/piglit/tree/tests/shaders ?

I do have about 500 random shaders from Unity here:
http://github.com/aras-p/glsl-optimizer/tree/glsl2/src/glsl/optimizer-tests/
(the *-in.txt files), but to prepare them for piglit I'd have to think
up some instructions to draw something and inspect the pixel values,
right?
