--- received arguments ---
PK_FACE_t        face,          --- a face

PK_FACE_t *const next           --- the next face (possibly PK_ENTITY_null)
)


This function returns the next face in the body which contains the given face.


This function should be used in conjunction with PK_BODY_ask_first_face to
scan the faces of a body, one at a time, in the same order as returned by
PK_BODY_ask_faces. If the face is the last in the body, then PK_ENTITY_null
will be returned.
