Do you know of any good, modern D-Paint clone that isn't Pro Motion (too expensive) or Grafx2 (which tries to be D-Paint a little too much to the point of replicating unusable by modern standards UI instead of general D-Paint philosophy such as brushes, easy gradient painting, auto dithering and so on)? After a bit of googling, I've learned about Swanky Paint, it's a step in the right direction, but it still isn't it.
