Before we do that... does this work on other implementations? I am very
surprised that this is valid, as it does not match recollection of how we
designed SSBOs. I'll be a little surprised if this works on other drivers.
Let's collection some information about that, then decide how to proceed.
Which ever way is determined to be correct, we should also add a test for the
CTS.</pre>
