 	  The <code>DeferredImageDescriptor</code> API has been added to JFace

 	  a URL, where the calculation of the URL is potentially costly
 	  (because it might involve searching through multiple directories or
 	  bundles/fragments on disk).
 	  <p>The new API can be called using
 	  <code>ImageDescriptor.createFromSupplier</code> along with a
 	  <code>Supplier&lt;URL&gt;</code> which will calculate on demand the
 	  URL when the image is acessed for the first time. This allows images
 	  registered at startup in an <code>ImageRegistry</code> to be deferred
 	  until the first time the image is shown on screen.</p>
