This PR include changes associated with the PanGestureRecognizer firing the Complete status if we move outside the View with the gesture limits. Feedback?

Is this expected? I think panning should work when the pointer goes out of the view, and only complete where the cursor is lifted. What happens if you hold the button down and drag out and while still holding, return to the view. I feel it should continue the pan?

This is not how it worked in Forms. And as far as I can tell, this is not how it works on any native applications. The pan gesture is "completed" when the touch is lifted, not when the touch goes outside the bounds of the view.

Thanks for the feedback. I've aligned behaviors across all platforms. In all cases pan gesture is "completed" when the touch is lifted (inside or outside the View where the gesture began).

Tested on Windows and Android. Was able to see the Completed event trigger when I let go inside and outside the original view. I am curious how to trigger the Canceled event though
