title: HTML5 Canvas - Fill circle with image
body: <p>How can I draw an image inside a circle? If I do:</p>
  
  <pre><code>context.beginPath();
  context.arc((e.pageX),(e.pageY),161,0,Math.PI*2,true);
  context.closePath();
  </code></pre>
  
  <p>How can I then use fill() to fill it with my drawn image?</p>
