Sieve for Dithering Patterns

1 bit “sieve” where the brush only draws on marked pixels on a 16x16 (or smaller) grid. A few basic preset patterns, the ability to save patterns, and shifting patterns would be great.

With a custom brush set to “pattern aligned to source”, the brush size is set. (unless you’re clever with select/fill but that’s tricky). A sieve makes drawing complex dithering patterns super easy.

Here’s a screenshot of the sieve tool in Graphx2:


Welcome @Ravancloak! There are several plans to improve the whole custom brush dialogs (with brush shape + different patterns, flip/rotation of the brush, brush presets, easier way to organize user brushes, etc.), some ideas from #175 too.

Ah, sorry I missed that one. Looks good!
