title: how to get X,Y coordinates of a movieclip (inside another movieclip) but relative to the _root?
body: <p>I have a movieclip inside another movieclip...</p>
  
  <pre><code>//create on the stage an empty movieclip... 
  var mc_container:MovieClip = _root.createEmptyMovieClip("container_name", _root.getNextHighestDepth());
  
  //new position on the stage...
  mc_container._x = 200;
  mc_container._y = 200;
  
  //create a movieclip inside the main movieclip...
  var mc_inside:MovieClip = mc_container.attachMovie("mc_from_library", "mc_name", mc_container.getNextHighestDepth(), {_x:0, _y:0, _alpha:100});
  </code></pre>
  
  <p>I can get mc_inside._x and mc_inside._y properties relative to the container movieclip, but how can I get the <code>mc_inside._x</code> and <code>mc_inside._y</code> relative to the <code>_root</code> (the stage)?</p>
