Title: Possibly more accurate selection (probably not really an issue)

I was looking at this excellent control in in the simulator and noticed that the transition from one highlighted segment to another seemed a little off.
I noticed that the touches were being resolved to self, rather than the _pieView, which may have been causing the slight offset issue.
I have updated the code to resolve touches in the _pieView and now it changes they highlighted segment as soon as my pointer (running in the simulator) crosses a boundary.
