title: KinectJS: Rotate an image about an absolute rotate point per drag and drop
body: <p>I'd like to rotate an Image about an absolute rotate point with kinectJS. For example about</p>
  
  <pre><code>var rotatePoint = {x: 500, y: 500}
  </code></pre>
  
  <p>The rotation schould be initialised by clicking at the image and moving the mouse, i.e. by dragging and dropping the image. Therby it schould rotate about the same angle, the mouse is drawing.</p>

  <p>Any ideas?</p>
  
  <p>Thanks!</p>
