Okay, looking about there's a few places where we could want dithering to improve gradients, all of these should be optional:

  1. Displayfilter, so that people have the feeling 16bit and higher is indeed as smooth as a babies butt.
  2. Gradients, primarily for drawing 8bit gradients.
  3. Converting from high bitdepths to 8bit
  4. Brush masks... aparantly the brushmasks currently give odd banding artefacts: https://forum.kde.org/viewtopic.php?f=288&t=132097&p=354832#p354832 dithering could deal with this.

So... Does anyone remember why this wasn't merged?

This is an updated diff against krita/4.1 for the dithering work:

I guess it just wasn't finished and worked only in few cases... and caused regressions in other cases
