This datatype is used to control on which side of a wall of faces the
blend lies.

    PK_blend_orientation_before_c   The blend lies in the direction of
                                    the face normals.

    PK_blend_orientation_behind_c   The blend lies in the direction opposite
                                    the face normals.

    PK_blend_orientation_unknown_c  Parasolid will attempt to determine the
                                    correct orientation.
