Okay. So the scheme would be:

image::notify() becomes layer::setDirty()

Layers keep a list of dirty rects

On grouplayer::projection() becomes grouplayer::projection(rect) and returns 
the whole projection, but only guaranteedly updated for the specified rect

paintview, merge, flatten etc. use the projection anyway, so no sweat. 


Note to self: expect trouble with the group & adj. layer thumbnails keep 
working.

If Adrian agrees as to the soundness of this scheme, I'll try to implement 
this tonight or tomorrow.
