oh sorry, I wasn't precise enough. I meant 1bit greyscale support for the encoder: https://github.com/image-js/fast-png/blob/bdb81f93cc55aa89b312b50e5e2e8a39cdbde657/src/PngEncoder.ts#L100 We are using fast-png to create, store and read bitmasks for that images with 1bit...

ok, so I gather there's no reason it wasn't done before just that there was no need up to now? Just making sure there's no reason like there's no good...
