Could Joel Yliluoma's color ordered dithering algorithm be implemented?

[MobyGamer]

You mentioned in your documentation that you were looking for a color ordered-dithering algorithm, but had reservations about one that took NTSC bleed into account. I'm not sure you'll find one specifically for that, but maybe it would be worth implementing Joel Yliluoma's arbitrary-palette positional dithering algorithm (https://bisqwit.iki.fi/story/howto/dither/jy/) as an option until you find ways to tweak it.

Ordered dithering is important for anyone attempting animation, as error-diffusion dithering doesn't lend itself to deltas between frames, whereas ordered dithering does and produces stable deltas.
