the real source of the banding (besides buffer precision issues) is the precomputed vector, but changing that means a pretty significant change architecturally.

Come on cairo!!!

Adding random noise to the gradients may help reduce the visibility of artifacts to the human eye, however. Gradients are rendered by selecting colors from a precomputed 1024-color vector, so adding a very small amount of noise to that index calculation should be sufficient.

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.
