So, is the idea to pass everything that is in brushsettings.json, so we can define new inputs including the min/max, etc on the fly? But what about calibration issues? Should...

Humidity. Haha. Don't give me ideas! I think I understand now, the idea is just to not break existing stuff. New inputs won't magically work, but that's a problem for...

I think it probably makes more sense to just flip pigment mode off if a brush is slow :-) Maybe just make it exact and optimize when `rgba[3] == 0...

Oh I didn’t know that the uint subtraction gets promoted to signed Int, so negatives are ok huh. I still wonder about comparing the alpha unassociated color (‘straight”) (r) with...

#74 should be preventing this crash as it makes the engine tolerant to unknown settings. Do you need a newer libmypaint 1.3.x?

Oh... dang. #74 probably only catches invalid _settings_, not invalid _inputs_. That's a bummer. @achadwick, how difficult is it to add this extra check? :-) I think those are the...

You're probably right, but it seems like this and #74 are bugs and not a reason to increment the brush version, right? In other words we should lock the current...

It's really a case by case for each brush, and the issue has been here forever. There are brushes that are worthless without pressure sensitivity. I've made some that really...

Actually, there is one other issue that I'm not sure how to solve. With 2.0 not only did new inputs come over, but the way speed is calculated was changed...

> Well then I guess you should just version the data directory: share/mypaint/ for libmypaint vs share/mypaint-2/ for libmypaint-2. What about git release tags? Or is it bad to rely...
