Distort MovieClip in Flash with AS3

As you probably know there is no simple way to distort a MovieClip in Flash. The solution that I've found uses AS3. Special thanks to Thomas Pfeiffer and Ruben Swieringa. They share their experience with this problem.

I successfully wrapped the code from here. As you can see in the example below I added a few properties to class that extends MovieClip. The usage:

    // just pass the MovieClip that you want to distort as a parameter of the DistortImageWrapper class
    var distortClip: DistortImageWrapper = new DistortImageWrapper(new TheClip());
    
    // setting the position of the top left corner
    distortClip.tlX = 120;
    distortClip.tlY = 75;
    addChild(distortClip);

The code of the example:

package {
      import flash.display.MovieClip;
      import flash.events.Event;
      import flash.events.MouseEvent;
      import ws.outset.display.DistortImageWrapper;
      import ws.outset.managers.tween.TweenManager;
      import ws.outset.managers.tween.TweenType;
      public class App extends MovieClip {
        private
        var _clip: DistortImageWrapper;
        public
        function App(): void {
          // adding the clip to the stage		
          _clip = new DistortImageWrapper(new TheClip());
          addChild(_clip);
          // distorting		
          distort();
          // adding buttons		
          addButton(new ButtonClip(), 400, 343, onButtonClick);
          addButton(new ButtonClip2(), 260, 343, onButtonClick2);
        }
        // distorting	
        private
        function distort(): void {
          // setting x of the top left corner	
          _clip.tlX = getRandomNum(0, 200);
          // setting y of the top left corner	
          _clip.tlY = getRandomNum(0, 200);
          // setting x of the top right corner	
          _clip.trX = getRandomNum(340, 540);
          // setting y of the top right corner	
          _clip.trY = getRandomNum(0, 200);
          // setting x of the bottom left corner	
          _clip.blX = getRandomNum(0, 200);
          // setting y of the bottom left corner	
          _clip.blY = getRandomNum(200, 400);
          // setting x of the bottom right corner	
          _clip.brX = getRandomNum(340, 540);
          // setting y of the bottom right corner	
          _clip.brY = getRandomNum(200, 400);
        }
        // tweening distortion
        private
        function tweenDistort(): void {
          TweenManager.tween(_clip, {
            tlX: {
              end: getRandomNum(0, 200),
              mtd: TweenType.OUT_EXPO
            },
            tlY: {
              end: getRandomNum(0, 200),
              mtd: TweenType.OUT_EXPO
            },
            trX: {
              end: getRandomNum(340, 540),
              mtd: TweenType.OUT_EXPO
            },
            trY: {
              end: getRandomNum(0, 200),
              mtd: TweenType.OUT_EXPO
            },
            blX: {
              end: getRandomNum(0, 200),
              mtd: TweenType.OUT_EXPO
            },
            blY: {
              end: getRandomNum(200, 400),
              mtd: TweenType.OUT_EXPO
            },
            brX: {
              end: getRandomNum(340, 540),

              mtd: TweenType.OUT_EXPO
            }
          });
        }
        // button	
        private
        function addButton(clip: MovieClip, xPos: Number, yPos: Number, callback: Function): void {
          clip.x = xPos;
