Is this substantially different than patch-single-vert.shader_test or
patch-pair-verts.shader_test? Is the 4 vertices that's important to
your test? If so, patch-four-verts.shader_test seems like a better
name.


That's a really bad name, because it doesn't tell me that the test is
trivial. See, I didn't even bother checking what patch-pair-verts.shader_test
does. Bad name.
