This test attempts to create a core profile in only one way: by omitting
GLX_CONTEXT_PROFILE_MASK, and relying on its default value. I quickly
scanned the rest of this series, and was unable to find a test that
set GLX_CONTEXT_PROFILE_MASK = GLX_CONTEXT_CORE_PROFILE with the intention
that glXCreateContext would pass. That's a path that needs testing.

I'm thinking that this test should have three bools, named something like this,
   got_compatibility
   got_core_with_mask_omitted
   got_core_with_mask_set
and check that got_core_with_mask_omitted if and only if
got_core_with_mask_set.
