Nevermind. That wasn't the problem... it was a bug in my app which is
now fixed :)

As an experiment, I'm writing a cocoa app that uses core graphics
(Quartz2D) to play a sequence of images (at frames rates around
15-30FPS).
The problem I'm having is that my app is calling CGContextDrawImage()
for the next image in sequence before Quartz has finished refreshing
my subclass of NSView's contents. Is there some kind of callback
function or something that I could use to ensure that graphics have
been fully refreshed on-screen before calling CGContextDrawImage()
again?
I've been writing Cocoa apps for some time now, but this is my first
attempt at including core graphics calls in them.
Any help would be appreciated :)
Thanks,
Andrew
