title: How to get a canvas to constantly redraw itself?
body: <p>I have a canvas in HTML5 and am making a networked painting application. However, when other clients receive the drawing code, it is not drawn on to the canvas until they mouse over it.</p>
  
  <p>Is there any way to fix it? I'd like the drawing to appear and update to other clients without them having to have their mouse cursor over the canvas.</p>
