Add a circular movement to the freelock view

As explained, the request is about to simulate a real head movement into the freelock view and into the laft right up down back views. L, taking account of a sort of fake head dimension. At the moment the freelock it's just a point moving, the problem is that if you use a cockpit body you'd need some pivot, or offset that simulate te rotation of the head taking account of the approximate distance and movement a real head do, let's say an offset of 10vm in all directions.
