title: Jsplumb change position of static anchor
body: <p>what i want to accomplish is that i can rotate jsplumb connections. You can use setAnchor to redefine an Anchor but i can't get it to work. I found this online and it works but it's not what I want. </p>
  
  <pre><code>jsPlumb.selectEndpoints("myclickedelement").setAnchor([ "Continuous", { faces: ["Top", "Bottom", "Left", "Right"] }])
  </code></pre>
  
  <p>I got an endpoint on the top and bottom of the object and when I rotate it i want them to be at the left and right without deleting the existing connections.</p>
  
  <pre><code>          jsPlumb.addEndpoint($(this).parent("div").attr('id'),     { anchor:[0.5, 0, 0, -1] },
  { isSource:true,
   isTarget:true,
   paintStyle:{ lineWidth:1, strokeStyle:'#ff8700' },
   connector: 'Flowchart',
   hoverPaintStyle:{ strokeStyle:"#ff8700", lineWidth:4},
    })  
  jsPlumb.addEndpoint($(this).parent("div").attr('id'),   { anchor:[0.5, 1, 0, 1] },
  { isSource:true,
   isTarget:true,
   paintStyle:{ lineWidth:1, strokeStyle:'#ff8700' },
   connector: 'Flowchart',
   hoverPaintStyle:{ strokeStyle:"#ff8700", lineWidth:4},
    })
  </code></pre>
  
  <p>This is what I have to create my objects with anchors</p>
