Title: Track intersection frame using UIWindow frame

Allow drop target view to be in another view subview instead of the
same subviews sibling as the scrollview.

Allow rect intersect tracking to be done on UIWindow frame instead of view frame (Which will not give correct result if the drop view is nested as subviews of another view)
