patch v1

While playing with the multi touch on Android, I thought it would be cool to have a "zoom" action, pretty much like what every smart phone have.
Here is a try that implements a drag as long as you have a single touch point and a zoom/scale once 2 touch points are on the actor.

I'm looking for reviews about the API, mostly the zoom_begin/zoom_update/zoom_end signals. I'm not sure emitting the distance between points is enough, maybe replacing that with the couple of points. But what structure?
