typedef int PK_BODY_sewing_removal_t;


Enum to indicate level of effort to remove duplications from input sheets to
PK_BODY_sew_bodies

    PK_BODY_sewing_remove_none_c - Don't bother at all

    PK_BODY_sewing_remove_poss_c - Identify possible duplicates to within
                                   modeller precision.

    PK_BODY_sewing_remove_cert_c - Identify, with reasonable certainty,
                                   sheets duplicated to within the
                                   tolerance specified by the gap width
                                   bound passed to PK_BODY_sew_bodies.

                                   PK_BODY_sewing_remove_cert_c will be
                                   slower and more successful in identifying
                                   duplicates than
                                   PK_BODY_sewing_remove_poss_c due to a
                                   greater effort made in comparing sheets.
