3 people 96ec16ed7d fix(compose, gpu): round dithered gradient fills to the document depth (#2755) (#2781) ...

A live gradient's dither adds a fraction of a level of noise, but gradient
fill layers kept it in float. Color Dodge divides by 1 - cs, so under a
bright dodge layer that sub-level noise came out as speckle several levels
high, and channels at 0 were lifted off black (coloured fringes).

Dithered gradient pixels are now rounded to the document depth's levels
(8/16-bit; float documents unchanged), as a painted gradient stores them.
Same rounding in the GPU shader. Regression tests in compose and a GPU
parity case for stacked dithered gradients under Color Dodge.
