Centered Flash with EASING?

programming flash
1

Some flash sites…have the swf centered in the browser…and when you resize the browser…the flash will automatically center itself (easily done by making it centerd)…but how do you make it EASE into the center?

I have been given the following code,

Code:
Stage.align = “TL”;
Stage.scaleMode = “noScale”;
_root.createEmptyMovieClip(“wallpaper”, _root.getNextHighestDepth());
_root.wallpaper.attachMovie(“bg”, “wallpaper”, _root.getNextHighestDepth());
wallpaper._x = Stage.width / 2;
wallpaper._y = Stage.height / 2;

var myListener:Object = new Object();
myListener.onResize = function(){
wallpaper._x = Stage.width / 2;
wallpaper._y = Stage.height / 2;

wallpaper.onEnterFrame = function(){    
    wallpaper._width = wallpaper._width + (Stage.width - wallpaper._width) * 0.3; 
    wallpaper._height = wallpaper._height + (Stage.height - wallpaper._height) * 0.3; 
}

}
Stage.addListener(myListener);

But that only centers a Background that you specify with the insance name “wallpaper” …it doesnt center the actual entire swf or main site…
