The shaders are generated by this code:
http://cgit.freedesktop.org/mesa/mesa/diff/src/gallium/auxiliary/util/u_simple_shaders.c?id=fc21098a95c8f7d0aadbfcc90cb2e9e78d1e2ef3

There is nothing special except for the texel fetch instructions which read
from MSAA textures. The shaders also contain float<->int and float<->unsigned
conversions. I think the latter is not used with GLSL very often.
