I'm wondering how scalable the Core Animation layer model is.

When a region of a layer-backed view is updated, does the CA system have a way 
to quickly identify layers for update, e.g. some sort of spatial hash, or does 
it simply traverse the whole tree looking for intersections? If the latter I 
would expect that not to scale so well to thousands of layers.

Some sort of indication about this would be a key decision point about whether 
to base a substantial update of DrawKit on CALayer or whether to stick to 
"rolling my own". There are lots of compelling advantages to CALayer, but 
scalability is vital.
