title: titanium using borderRadius setting with imageView
body: <p>i'd like the imageView "image" property to have a border around it. However, on the android system, this doesn't work - at least, not in the developer view-thingy. </p>
  
  <p>What happens is the image shows up, no border. I think it is somehow sitting "on top" of the border... is there some way to set a border on an imageView image?</p>
  
  <p>And no, i don't necessarily control the image... so i cannot just manually add a border to it!
  Also, i mean:</p>
  
  <pre><code>var theImage = Ti.UI.createimageView({
      borderRadius: 5,
      ....
  });
  theImage.image = "xyz";
  </code></pre>
  
  <p>where, in the above scenario the borderRadius isn't being observed!</p>
