I'll do a quick check to see that webkit layout tests still pass and, more
importantly, that there's no weirdness when zooming the noise.

There should only be a change if webkit called setLocalMatrix on the noise
shader (which I don't think they do). Otherwise the localmatrix is identity, in
which case the order won't matter.
