title: UIImage resizableImageWithCapInsets cap data
body: <p>I've used stretchable images before and whenever I use them I have to manually type in the cap insets and if I get them wrong the image looks wrong.</p>
  
  <p>Is there any way of "implanting" the cap data into some file that can then be read along with the image.</p>
  
  <p>i.e.</p>
  
  <pre><code>UIImage *image = [UIImage loadResizableImageWithFile:"someFile"];
  </code></pre>
  
  <p>That way the designers can input the cap sizes of the image instead of me having to type them in manually.</p>
