I think this test file is a bit special: It actually wants to test
different formats based on which context type.  So if one were trying to
run a test of GL functionality but didn't care about looking for context
differences (for speed, similar to how we don't test all visuals), you'd
still want to run the ARB and core variants of this test, unlike say
glsl 1.30 tests where you're probably getting fine coverage on just one
type of context.

Maybe once piglit grows more context selection support (with a notion of
tests that are fine on any context they support vs ones that want to
iterate contexts) we'll want to revisit this, but it seemed reasonable
for the moment.

One thing I'd be interested in is a flag to force a profile regardless
of what the test announces.  This would be useful to quickly poke a test
and decide whether the porting effort to allow core-only looks
