        This sample shows how to show a popup when the mouse hovers over or touches a shape.
        This sample uses the mouse move event to detect when hovering over a shape instead of the mouse over event.
        The mouse enter and over events only fires when initially hovering over a shape in a layer.
        If two shapes overlap, these events won't fire again. The mouse move event will fire while moving the mouse over shapes in the layer.
