Description of fields:



'surface'                Replacement surface for the relevant face.


'sense'                  Replacement surface orientation. For a particular
                         face/surface combination, this flag is interpreted as
                         follows :
                            PK_LOGICAL_true :
                               When the new surface is attached to the face,
                               the face normal must be in the same direction
                               as the natural surface normal (as calculated by
                               the function PK_SURF_eval_with_normal).

                            PK_LOGICAL_false :
                               When the new surface is attached to the face,
                               the face normal must be in the opposite
                               direction to the natural surface normal
                               (as calculated by the function
                               PK_SURF_eval_with_normal).
