title: Can I apply offset to continious anchor in jsplumb
body: <p>I want to use the "continuous" anchor placement option in jsplumb.
  This works great, but the anchor is placed half inside the container div and half outside of the container.
  I would like the anchors to be completely outside the container div.
  If possible event with a small space between the div and the anchor (one or two pixels).</p>
  
  <p>My purpose is to put those anchors on top of the arrows of the connections. I then want to make the anchors transparent so the user can "click on the arrows and drag". 
  This is required because we are rebuilding an old java-based diagramming application. Our users are used to click and drag the arrows.</p>
  
  <p>So can I offset the anchors so they will be x px outside the container div?</p>
  
  <p>Thanks</p>
