title: SwingController get page coordinate
body: <p>Using <code>IcePdf</code> (ver 1.8) i integrate a <code>SwingController</code> into my <code>JPanel</code> to use it in my application. Since the page displayed into the <code>SwingController</code> is in a specific position into the controller.
  How can i obtain the coordinate of the page (top left corner for example, o bottom left if using PDF coordinate) relative to the whole <code>SwingController</code> so i can obtain the Page coordinate relative to the <code>JPanel</code> ?</p>
  
  <p>I searched deep in the API of IcePDf but i cannot figure out how to do this. Thanks.</p>
