[Tweener] Mouse-Drag Tweening

[Makc]

well, I assume those clips are expected to follow the mouse in some
way; if that's not the case, what I said doesnt make sense to you for
a reason :) if that is the case, imagine if on every mouseMove event
you do

Tweener.addTween (clip, { x: mouseX + 10, y: mouseY + 20, time: 0.5 });

then previous tween gets cancelled, and the clip is instructed to get
into new position after 0.5 seconds. Now, if two mouseMove events are
registered at 20 pixels away from each other (user moves mouse
slowly), you have 20/0.5 = 40 pixels per second average speed for your
clip, but if two mouseMove events are registered at 200 pixels away
from each other (user moves mouse fast), you have 20/0.5 = 400 pixels
per second average speed for your clip. So you have this kind of
relationship automatically.
