If I understand what you're saying, you're making the claim that doing things
through the Quartz layer may give you speed advantages because it is going
through a different, possibly faster, path to the video hardware.
I guess I can see the argument, but I'm skeptical that it's true. However, I
have no empirical evidence to say that doing an operation through raw XFree86
on darwin is faster than doing the equivalent operation in Quartz.
It would be interesting to find out, though!
