glsl: Implemented most of the missing srcmods. Reread the GLSL spec, and it turns out that "vec3(x,y,z) - 3.0" is legal syntactic sugar: the compiler knows to subtract 3.0 from each of the three components in that vec3. This made this simpler than having to tapdance to generate correct constant vectors ourselves, and it's easier to read.


# !!! FIXME: use this to correct our estimates some day.
