Hi Rob!
Thank you for writing. I suppose the only way I'll know for sure is to
test this with both.

You could do it this way, although normally for something like this
I'd use Core Image. Make two CIImages and use an animated transition
CIFilter.
I will take a shot at this. My concern is that I've seen CoreImage
transitions bog down initially, I guess in their loading phase or
something. I have an early model G5 that I use for testing the low
end of the Leopard range (and it still looks strange to say G5 and Low
End in the same sentence). On that machine, apps that use CoreImage
tend to have a visual stutter initially, and I'm not sure if that's a
CI thing or an app specific thing. Is there a 'push' effect for CI
though?
That said, CoreImage would theoretically work with Tiger as well, and
providing backwards compatibility is something I'm considering anyway.
Hmmm. I'll have to test both. Excellent suggestion!
Thank you!
