EaseOut stuttering [subpixel problem?]

[GoogleCodeExporter]

When I use a simple EaseOut animation to rotate and move an item:
Actuate.tween(item, 2, { rotationY:90, x:10, z:10 } ).onComplete(function() {});
its a bit stuttering at the end (subpixels?). It will stop for some frames and 
then move a pixel at the end. Is there some kind of rounding problem somewhere 
in the easing functions? Flash-Tweens [AS3 based] don't stutter and ease out a 
bit better

Here are some graphs of various easing equations:

Expo.easeOut is the default equation for Actuate. As you can see, however, it 
has a lot of lead out time, so if you have a long tween over a short distance, 
you may be able to see this type of problem.

Here are two ways that animation may become smoother:

Actuate.tween (item, 1, { rotationY: 90, x: 10, z: 10 } );
Actuate.tween (item, 2, { rotationY: 90, x: 10, z: 10 } ).ease (Quad.easeOut);

You can play with different easing types to find something you like. If you 
prefer a different easing style for all your animations, you can set Actuate's 
default, like this:

Actuate.defaultEase = Quad.easeOut;

All of the easing equations are located in the
