Extract more of the mouse logic from EventHandler
Extract the mouse logic to the extent that
GestureManager can use solely MouseEventManager

private functions. Also this refactoring cleaned
up some parameter passing from EventHandler to
MouseEventManager that was going through
PointerEventManager functions.
Initial refactoring
