We can look at the luma to test correctness,
which lets G8 destinations be tested correctly.

Today's shader hash changes if the unordered set of {r,g,b,a} values we
produce changes, but is not sensitive to simple order changes like
sampling RGBA vs BGRA.
Folding in a hash of each value's ID in order will fix this.
This has been difficult to track down (thread-local caches),
so I've added a GM that reliably reproduces the bug.
