0.4.0 "Lo-Fi Dithers to Study and Relax To"

This release adds a new dither, LOAF, and makes small adjustments to DODGY (added earlier, in 0.3.15). This has one breaking API change (barely): the removal of an undocumented public field, reverseMap in PaletteReducer, because it was only used in PATTERN dither and wasn't even helpful there. As for LOAF, it's a low-fidelity dither that typically only mixes two colors per 2x2 pixel area, though if the original area had 3 or 4 very different colors in that area, it could use up to 4 colors. LOAF tends to look much more like a hand-drawn pixel art dither than the others here, though it may look too simplistic to seem made by a human. It looks good when dithering pixel art, and not very good for high-detail images like paintings or photos. DODGY had very subtle changes, but it tends to look smoother/less-noisy now and has fewer repetitive artifacts, at the expense of not being quite as accurate at matching hue (still better than NEUE, but worse than WOVEN).

Good luck on your animating, image-writing, dithering adventures!
