Well, it is often seen as inferior open source attempt at photoshop, so it just might! It certainly can do more than paint.

Here is a tool I've used in a few tests but I don't think I ever used it an edit. You make a cage around an area and then can move the nodes to stretch it or shrink it. Hence the name Cage Transform.
