title: canvas.toDataURL Alternative?
body: <p>I'm trying to convert an the contents of an HTML5 canvas to a png image. </p>
  
  <p>Problem is that the canvas contains an image that isn't hosted locally so I get the security error. </p>
  
  <p>I don't have the option to host the image locally, is there any other way to capture what is inside the canvas element?</p>
  
  <p>Thanks! </p>
