Yeah.  The primitive-restart test is fairly complicated already.  In 
my experience, the more complex the test, the harder it is to 
debug/diagnose a failure.

Can you get by with a new, simpler test for xform feedback + restart?
I'm guessing you'll be examining the contents of the feedback buffer 
rather than on-screen rendering to determine pass/fail.  That's a 
different approach than the current test so a new test seems more natural.
