title: Change size of showCamera overlay
body: <p>I am trying to add additional interface elements to a showCamera display in my iOS app.</p>
  
  <p>I know I can add an overlay with the code below. The problem: This overlay will <strong>always</strong> have the size of the entire screen. This is a problem as the camera's default control elements (flash, HDR, camera switcher) are not accessible anymore.</p>
  
  <p>Setting <code>touchEnabled: false</code> in <code>createView()</code> makes it so that all events are passed through. This makes the original control elements work, at the expense of my new elements not being accessible at all.</p>
  
  <p>So my idea was to make the view smaller so that it would not obstruct the original elements at the top. My own controls would be positioned on the middle/right, so no conflict there. However, no such luck.</p>
  
  <p>Setting <code>height</code>/<code>width</code> attributes in <code>createView</code> does nothing. Setting these properties later on (either directly or through <code>animate()</code> has no effect.</p>
  
  <p>My simplified code:</p>
  
  <pre><code>var myOverlay = Titanium.UI.createView({
      backgroundColor: '#0F0', // just to see what is happening
      height: 200 // does not work
      // touchEnabled: false
      // touchEnabled apparently can't be re-enabled for objects contained within this view.
  });
  
  var mySlider = Titanium.UI.createSlider({
      [...]
  });
  myOverlay.add(mySlider);
  
  Titanium.Media.showCamera({
      overlay: myOverlay,
      [...]
  });
  
  myOverlay.height = 200; // does not work
  myOverlay.animate({height: 200}); // does not work
  </code></pre>
  
  <p>All these methods to control the height do work when I add the same overlay to a Window or another overlay. Not so when I use <code>showCamera()</code>.</p>
  
  <p><strong>Question</strong>: How do I control the size of the <code>myOverlay</code> or how do I otherwise make the standard control elements accessible while also letting me throw in my own controls?</p>
