Director-like multi-image "sprite" animation

[Malte Brill]

FWIW here are my 2 cents.

The most difficult problem you´ll face is how to react if a "frame"  
gets dropped. Slower machines may not be up to the challenge to render  
a complicated animation, or if the user has many apps open at the same  
time (and mail is starting to download many emails in the background  
for example) the animation might start to stutter. So it is a good  
idea to compute where the control must be located at the given point  
in time. I have done many experiments with this and some of the  
results went into animationEngines AEMoveTo handler. That one will  
tackle dropped frames and position the moving objects correctly to the  
given point in time. The next version of ae will have this for the  
other moving methods too.

Hope that helps a bit,
