title: Display pointer cursor when hovering paperjs item
body: <p>I would like the mouse cursor to be a pointer when hovering a <code>Paper.js</code> item.<br>
  I have found nothing allowing this in the <a href="http://paperjs.org/reference/global/" rel="nofollow noreferrer">documentation</a>.<br>
  Is that possible ?</p>
