title: How to place text object successfully under an image/polygon object with jsxgraph 0.99.7?
body: <p>I would like to simply place a text object under an image object I created using jsxgraph.  </p>
  
  <ul>
  <li>Tried setting for the text object layer:2 and the image object layer:7.</li>
  <li>Tried setting board.options.layer.text=2, then created the text object, then set board.options.layer.text=9 again.  </li>
  </ul>
  
  <p>The object does give the correct layer value when investigating, however it does not visually do this. This works well for non text objects. Would this a text related bug? </p>
