Re: replacing NSViewAnimation with CoreAnimation

Well the problem/question is:
Is NSViewAnimation SLOWER then CoreAnimation (because it uses no 
layers).
If so I would use NSViewAnimation for Tiger and CoreAnimation for 
Leopard.
But there is no reason why Apple didn't rewrite some of the 
NSViewAnimation code for Leopard. I'm technically it's teh same thing 
I'm doing here. Intercepting ViewAnimations put them in a animation 
context and fire them together.

SO the Question is: Is NSViewAnimation under Leopard as fast as 
CoreAnimation (and uses layers) or not?

All the best
