I think this is a good idea.  You might want to borrow some ideas from 
kdegraphics/kolourpaint/tools/kptool.h for further tool abstraction (it even 
handles status bar messages that reflect the tool state).

How would that work with KisPainter which only accepts integer coordinates?  
I'm currently working on a few more KisPainter methods (polyline, polygon, 
fill) ... been rather busy lately though; haven't had much time to do 
anything Krita related.
