title: Stretching a UIToolbar background image when rotating to landscape
body: <p>I am adding an image to a UIToolbar's background in the App Delegate using this code:</p>
  
  <pre><code>[[UIToolbar appearance] setBackgroundImage:
  [UIImage imageNamed:@"toolbarbackground.png"] 
                               forToolbarPosition:0 barMetrics:UIBarMetricsDefault];
  </code></pre>
  
  <p>The image is 768 pixels in width (the size of the iPad screen width in portrait orientation). When I rotate to landscape the image does not stretch to fill the new screen width (1024 pixels). How can I use a custom background image on a UIToolbar that stretches to fit the screen when rotating?</p>
