How should we use RxBinding with GestureDetector and GestureListeners ?

[Lakedaemon]

We can observe MotionEvents but, if I'm not mistaken, a GestureDetector is used through inheritance in the onTouchEvent Method of a view (i.e it takes code to set and unset) and intercepts (or not) motion events

What would be the best way to observe the many events provided by the gesture detector ?

There was an early proposal in #128. I'm open to something like this, I just haven't had the time to invest in looking into it.
