Took some time to add a few more error diffusion based dithering to the paletteuse filter: Sierra3, Burkes and Atkinson.

All the dithering in 1bpp can be observed here: imgur.com/a/2a1p4R8

Les capsules du prof Lutz

@bug J'adore ces clichés monochromes (ça me rappelle l'interface de NeXTStep en 1990 et le dithering du DPS vers l'imprimante NeXT Laser Printer). Les processus de dithering m'ont toujours fasciné car ils allient maths et physiologie de la perception (donc, biologie). Faudrait bien un jour que je m'attarde à comprendre le dithering temporel des signaux *audio* .

@lutzray in the end, everything is a signal. Video, audio, all the same :)
