kris 82e5779a3a Allow modeling screen as 140x192x16 pixels (i.e. ignoring fringing) or ... 560x192 where each pixel has a choice of two colours. The latter doesn't give good results currently, it produces long runs of colour, presumably when the immediate next choice for dithering is worse than the current one. i.e. it gets easily stuck in a local minimum. Looking ahead N pixels and computing the 2^N options should improve this.		2021-01-03 23:23:15 +00:00
