We had that with the bottom-up recomposition strategy, but that was quite hard 
to implement with the current top-down recomposition strategy. I've also got
some (uncommitted) code that adds recomposition thread queuing, but I'm coming 
to the conclusion that to make that work, I need to move setDirty from 
KisNode to KisImage, and that may break stuff again. (But it's still part of 
the 2.0 todo -- reenable threading for recomposition).
