title: Flash MovieClip extend
body: <p>Question: In Flash ActionScript 3, I extend a MovieClip as show below.
  <br>
  But when I create a ToolBar with ToolPictures, and set Xscale and Yscale, then it doesn't resize if I use cMyClip, it works correctly when I use MovieClip.</p>
  
  <p>Am I missing something ? Or is extending not the same as inheritance ?</p>
  
  <pre><code>package 
  {   
  import flash.display.Stage;
  import flash.events.MouseEvent;
  import flash.display.MovieClip;  
  import flash.display.Bitmap;    
  import flash.display.BitmapData;
  import flash.display.Scene;
  import flash.display.Sprite;
  
  
  class cMyClip extends MovieClip 
  {
      public var strToolTip:String="test";
      public var load_width:Number=0;
      public var load_height:Number=0;
  
  
      public function cMyClip() //:cMyClip
      {
          super();
      }
  } // End Class
  } // End Package
  </code></pre>
