I'm working on making it use A/NSAnimation, so that it can be
standardised. NSAnimation uses a timer internally too, by the way.

Please update your working copy. I've added a ton of easing functions.

You *must* use the delegate to update/animate, unless you prefer
subclassing. Please see the test file
/trunk/test/org.actionstep.test.ASTestAnimation for an example.

You shouldn't face much difficulty, because views use movieclips
anyway. Say you want to move a window accross the screen:
animationDidAdvance:function(anim:NSAnimation):Void {
win.setFrameOrigin(win.frameOrigin().translate(
foo.currentValue() * dx + sx, 0));
// force update
win.displayIfNeeded();
}
