Click incorrectly handled if mouse moved while the window wasn't focused

[Canop]

How to reproduce :

1. open this official tutorial : http://www.createjs.com/tutorials/Mouse%20Interaction/basic.html
2. click the red circle
3. move slightly your mouse to leave the circle
4. hit enter to close the dialog
5. not moving the mouse, click again : you see the dialog opening again as if the mouse were on the circle

Why :

It's because of an optimization in stage.js where the mouse position isn't forwarded on click on the basis the computations are done on move.

How to fix :

One way would be to change the _handleMouseDown function like this :

_handleMouseDown = function(e) {
        this._handlePointerDown(-1, e, e.pageX, e.pageY);
};

The cost would be to do at each click the same computation that is done on each move. I don't personally think it's important.

Here's a demonstration of how this fix would behave : http://dystroy.org/stackoverflow/EaselJS_bug_moveUnfocused.html

Good catch. I have incorporated this fix into the NEXT build and pushed an update. As you guessed, the performance impact is insignificant.
