/**
   Notes on Nicolas Toussaint changes


   A) XXButtonInteractionStyle became XXButtonInteraction : shorter

   B) Differentiation between zoom and pan is handled here, Pan is still work in progress

   C) PropagateCameraFocalAndPosition() is equivalent to sync. panning, so panning should be an event
   and synchronization of it should be in the collection.
