title: AS3: Extending Loader, how to draw border on its content
body: <p>I'm extending <code>Loader()</code>, is it possible to draw a border around the content without resorting to some hacks? I understand Loader can't have any additional children, otherwise I would just create a shape to the contents size and add it. But is there a way to coerce or cast the content object in order to use the drawing API on it?</p>
