Well, part of Krita's vision is that krita can be used for matte painting, and that's \
where a resynthesizer plugin will come in very handily :-)

No -- strokes in Krita are actually actions with a begin, middle and end that can be \
started and run on while you can start another stroke. Brush strokes end up as \
pixels, so all that is transparent to you, it would just be that you have a selection \
and run the filter on the selected pixels.

Chances are that if there are two users for your library that, if you do releases, \
distributions will start packaging it. We also got them to package Vc, for instance.

Hm, that's a bit outside my field of experience. To port it to gmic, you'd probably \
need to rewrite it in g'mic's scripting language.
