Incremental painting in paint tools

[Dmitry Kazakov]

Good evening, everybody!

Could someone explain me, what is (was) "incremental painting" (and (!
KisTool::m_incrementalPainting)) used for?
What is it supposed to do and what is it's current state?

I simply get a bit strange behavior with it, freehand tool and new memento
manager. There are two KisTransactions created during one single click on
canvas and massing COW'ing comes. I'm thinking it over atm... =)
