title: Performance issues using images with arbor.js
body: <p>I've been working on adapting arbor.js to use images. </p>
  
  <p>However, being a relative JS noob what I have is totally un-optimised. </p>
  
  <p>As far as I can tell, the way I've set it up is recreating the image object for every image and every frame, resulting in tons of flicker. </p>
  
  <p>Can anyone suggest a way to move the new Image() stuff out of the redraw function into the initiation? As far as I know this is a basic OOP issue, but totally stuck.</p>
  
  <p>Thanks!</p>
