[needs testing] First testing packages for the lager-based brush editor

Hi, @freyalupen and @sooz!

Thanks a lot for your testing! It looks like @freyalupen has found a real bug. I have just pushed a fix into my branch.

If you want to test again, here is a package for Linux. Though it is not strictly necessary now :slight_smile:

Linux AppImage X64: krita-5.2.0-prealpha-c2669a36c24-x86_64.appimage — Яндекс.Диск

My current plan is to devote a bit of time to documentation, so there might be no updates in the next couple of weeks. And then I’ll return to porting the rest of the brush engines.
