[Tweener] Tweener clip memory buildup?

[Zeh Fernando]

Not sure about the garbage collection issue, but normally, you'd do it this
way:

Tweener.addTween( avatarExitPopup, { _xscale:1, _yscale:1, _alpha:0,
time:.3, delay:3, transition:"easeInOutCubic", onComplete:function() {
this.removeMovieClip(); } } );

Or with parameters:

var avatarExitPopup:MovieClip;
avatarExitPopup = etc....
Tweener.addTween( avatarExitPopup, { _xscale:1, _yscale:1, _alpha:0,
time:.3, delay:3, transition:"easeInOutCubic",
onComplete:function(target:MovieClip) { target.removeMovieClip(); },
onCompleteParams:[avatarExitPopup] } );

On the above example, you could have a separate function instead of creating
an anonymous function on every removal.

Or even, specifically for this case, because it takes no parameters:

Tweener.addTween( avatarExitPopup, { _xscale:1, _yscale:1, _alpha:0,
time:.3, delay:3, transition:"easeInOutCubic", onComplete:avatarExitPopup
.removeMovieClip } );
