Updating the touch proxy logic:

In draglayer, we always dispatch touch events to child views. If the
touch originated from gesture area, when we dont route it through touch
controllers.
The proxy events are only send to touch controller. If any controller consumes
the event, then we cancel the view touch (pilferPointers)

This allows the controllers to work outside the dragView area, and prevents normal
view interaction when there is a window on top (like keyboard) while keeping our
activity focused
