title: ColorTransform removes shadow
body: <p>I've got movie clip on stage that has shadow filter.
  When I apply ColorTransform to that movie clip, the shadow removes.</p>
  
  <pre><code>        var ct:ColorTransform = new ColorTransform;
          ct.color = 0x99CC00;
          lamp.transform.colorTransform = ct;
  </code></pre>
  
  <p>How to save shadow?</p>
