title: Set background color for Dialog titlebar?
body: <p>I'm creating a class derived from Dialog. The titlebar of the dialog looks really nice, it's a dark grey color that is somewhat transparent. Is there a way to set the color used for the background of the titlebar? The grey is cool, but I would like to set it to some custom color. I don't think this is possible, I think I'd need to supply my own stretchable background dialog resource. Is that right?</p>
  
  <p>Thanks</p>
