 * SYNOPSYS:
 *
 *   The RoadMap lines are described by the following table:
 *
 *   line          the ID of the line and its from and to points.
 *                 The lines are sorted by square.
 *   bysquare      an index of lines per square.
 *   bysquare2     A given line may have one end in a different square:
 *                 this other index covers this very case.
