Repaint strategy for 2.0

[Boudewijn Rempt]

Anyone who's started Krita 2.0 will have noticed that we have to rethink our 
repaint strategy for 2.0. We are no longer supposed to paint outside the 
paint event, which we do in many places, because that's not OS X compatible. 
And apparently simple cursor movements already trigger repaints. 

Bright ideas? I was thinking of painting onto a QImage and having the canvas 
widgets hold a reference to that -- but there must be a better way. And 
perhaps we should take the jump and redesign the whole thing aroung the Qt4 
way of doing?
