Vista aero glass effect

[telit]

I want to write the Glass Effect from AS2 to AS3 but I’ve got some errors. Could you help me?
AS2 working version

import flash.filters.*;
import flash.geom.*;
import flash.display.*;

class GlassWin extends MovieClip{
	private var glassColor:Number=0xD9FFFF;
	private var glassAlpha:Number=35;
	private var mousePoint:Point;
	private var alphaScreen:MovieClip;
	private var blurScreen:MovieClip;
	private var blurBitmap:BitmapData;
	
	public function GlassWin(){
		var w:Number=Math.floor(_width);
		var h:Number=Math.floor(_height);
		var lowDepth=0;
		//всех поднимем на 2, чтоб освободить место для скринов
		for(var i in this) {
			if(this*.getDepth()<lowDepth)lowDepth=this*.getDepth();
			_root.swapDepths.call(this*,this*.getDepth()+2);
		}
		//////////////
		var bounds=getBounds(this);
		alphaScreen=this.createEmptyMovieClip("alphaScreen",lowDepth+1);
		blurScreen=this.createEmptyMovieClip("blurScreen",lowDepth);
		alphaScreen._x=blurScreen._x=bounds.xMin;
		alphaScreen._y=blurScreen._y=bounds.yMin;
		alphaScreen.beginFill(glassColor,glassAlpha);
		alphaScreen.lineTo(w,0);
		alphaScreen.lineTo(w,h);
		alphaScreen.lineTo(0,h);
		alphaScreen.endFill();
		////////
		blurBitmap=new BitmapData(w,h);
		blurScreen.attachBitmap(blurBitmap,0);
		getScreen();
		render();
	}
	
	function onPress(){
		mousePoint=new Point(_xmouse,_ymouse);
		onEnterFrame=render;
	}
	
	function onRelease(){
		onEnterFrame=null;
	}
	
	function render(){
		_x+=_xmouse-mousePoint.x;
		_y+=_ymouse-mousePoint.y;
		mousePoint=new Point(_xmouse,_ymouse);
		getScreen();
		updateAfterEvent();
	}
	
	function getScreen(){
		var p:Point=new Point(_x,_y);
		_parent.localToGlobal(p);
		var tx:Number=-(p.x+blurScreen._x);
		var ty:Number=-(p.y+blurScreen._y);
		var mtrx=new Matrix(1,0,0,1,tx,ty);
		_visible=false;
		blurBitmap.draw(_root,mtrx);
		_visible=true;
		blurBitmap.applyFilter(blurBitmap,blurBitmap.rectangle,new Point(),new BlurFilter(10,10));
	}
}

My version AS3 (getting some errors…)
