Ok, as of r15880 I've added a little bit of noise to gradients using a
linear feedback shift register. I would consider this pretty
experimental and it might get reverted later.
I'm mainly curious to see how much this helps perceptually; the real
source of the banding (besides buffer precision issues) is the
precomputed vector, but changing that means a pretty significant change
architecturally.
