Feature Proposal

Currently, when you set a borderWidth to an arc element, the width of the border is ignored by ArcElement when inRange method is invoked.
When a lineWidth is set before drawing on the canvas, half with is part of the shape itself but half width is drawn outside the shape.
In my opinion, but correct me if I'm wrong, the border width should be take in consideration as part of the element.

If you move the mouse, hovering the pie chart, you can see that the border will appear when the mouse point is in the middle of the border.

Possible Implementation

I havent seen the arc element code yet, therefore I can only write now, it should be considered.
