title: html5 canvas - animating an object following a path
body: <p>I'm a bit new to canvas and such so forgive if it's a trivial question.</p>
  
  <p>I'd like to be able to animate an object following a path (defined as bezier path) but I'm not sure how to do it.</p>
  
  <p>I've looked at Raphael but I can't work out how to follow the path over time.</p>
  
  <p>Cake JS looked promising in the demo, but I'm really struggling the documentation, or lack thereof in this case.</p>
  
  <p>Has anyone got some working example of this?</p>
