Tooltips not showing on Firefox 19.0.2

Hi,

First of all, thank you for your excellent work on Chart.js. You did exactly the additions I needed.
I have a rendering problem with Firefox (it works perfectly on the latest Chrome and IE 9), the tooltips do not appear at all. And sometimes, I get the following error:

TypeError: Value not an object. (l. 262)
context.putImageData(chart.savedState,0,0);

Do you experienced a similar thing ?

Thank you.

Ok, the error seems to be also in Chrome

Uncaught Error: TypeMismatchError: DOM Exception 17 chart.js:263
context.canvas.onmouseout

And seems to be generated when the chart is not loaded yet (animation in progress) and when the mouse moves over it.

By modifying the onmouseout function (l 261) so I did not seem to have any side effect, and this removes the errors:

context.canvas.onmouseout = function(e) {
  if (chart.savedState! = null) {
    context.putImageData (chart.savedState, 0,0);
  }
}

Hope it help.
But in Firefox still no tooltips :(

It was the using of e.x instead of e.clientX and e.y instead of e.clientY on the mouse movement event object.

Chrome supports e.x and e.y, Firefox doesn't and it seems clientX/clientY is the more standard way.
