Reason for revert: <INSERT REASONING HERE>
Original change's description:
> Improvements to GPU dither.
>
> 1) Makes the range of the offset dependent on the config.
>
> 2) Uses an ordered dither on GPUs that support integers in shaders.
>
> 3) Enables dithering for all paints with dither flag when the color type of the dst is 4444
>
> 4) Dithers r,g,b and clamps to 0,a rather than dithering all four channels (same as CPU backend).
