And then you'll have this problem again as soon as you want llvmpipe
to reach GL 3.00+/GLSL 1.30+.  So why not find a definitive solution
now?

Previous code converted the instance id to float, and said "it's an
integer guv', honest".  That does not fly in the face of native
integers, at all, unless you like your second instance to be numbered
1065353216.
