** x1, y1, x2, y2 segment to be added to statistics
** Globals: none
** Operation: This routine adds the statistics for the specified
** line segment to OutlineStats. The statistics that are
** kept are:
** sum of length of all segments
** sum of 2*Mx for all segments
** sum of 2*My for all segments
** sum of 2*Mx*(y1+y2) - L*y1*y2 for all segments
** sum of 2*My*(x1+x2) - L*x1*x2 for all segments
** These numbers, once collected can later be used to easily
** compute the center of mass, first and second moments,
** and radii of gyration. (see Dan Johnson's Tesseract lab
** notebook #2, pgs. 74-78).
** Return: none
** Exceptions: none
** History: Fri Dec 14 08:59:17 1990, DSJ, Created.
