A minimal sample with a static and a dynamic actor follows, at the
moment there is no way to apply force or torque to an actor
programatically (it only happens as a consequence of manipulation or
indirectly when colliding with another actor that has had its linear
velocity set.) See bug #1146 in the clutter bugzilla, patches are
welcome.)
