clean up isolated pixels dither (approximate gradients)

If something real (like clear sky) gets cut away, untick "Remove plain background". "Dither" fakes smooth shading with tiny dots, good for skin, sky and fur. "Oklab" picks colours the way the eye sees them. "Outline expansion" (1 to 2) keeps thin lines alive at small sizes.
