@timotheegiet @woltherav A new icon would be great. Thank you! It's far beyond my artistic abilities :)

Fixed the diff. Previous one was against wrong version.

Thank you for the careful review. Using KisTransactionBasedCommand simplified undo handling a lot!

Rewrote healing brush to use decorator. Changed ui to adjust brush size using keyboard and toolbar size control. Rewrote image access using Applicator based undo/redo interface.

I guess that one reason to use a mask and not a canvas decoration is that the inpaint tool can be used with any brush engine.

I doubt there is any use in allowing multiple brush engines for painting healing selection. It'll create more troubles than benefits, like in Colorize mask, where it is still in todo to disable incompatible presets for it. I guess simple pixel brush is the only thing compatible with it.

Description is incorrect. I don't know where arc got it from :) . It wasn't me :)

I added support for all color depths to inpaint tool. It was planned all along but slipped my mind.

This change adds a few strings that need to be i18n

Demo of the new inpaint tool from my branch:

Fixed.

Actually, I'm going to change my mind. PythonQt may still be the simplest path to enabling krita scripting.

I did a bit of testing and I think I can kill the PythonQt idea. PythonQt seems to have limited capability of automatically wrapping C++ objects.

Yes. I'll adopt the poor orphan :)
