This seems to be causing problems for me here on gcc8 (8.0.1 and
8.2.1) in Fedora 28.

./bin/texelFetch fs usampler2DMS 2

is failing here with:
Failed to compile fragment shader: 0:6(1): error: invalid input layout
qualifier used

gcc is probably broken, but we might want to revert his from the tree
and upcoming release until we can figure it out.
