Just an idea - one could keep the above in the commit message since it
gives nice reference points - mesa bug, piglit test ran against, etc.

Seems like many of the older piglit tests 'short circuit' as soon as
the first sub test fails. Can you please use the (newer) approach
which doesn't do so - pass = foo() && pass;
This allows one to see all points of failure at once.

Thanks
