       The vector object is not a particularly compact representation of itself, since it contains many 2-vertex
       segments which could be combined into a longer polyline.

       Bdy()  is a function which takes a geom as its argument.  The geom is then converted to a polylist, which
       is compressed (See plconsol(3).  Bdy() then counts the number of edges in the polylist used once and only
       once, and returns a vector object containing these edges.  The precision, prec, is used to determine  the
       maximum distance between vertices which may be considered identical.  If the vertices must have identical
       coordinates, this value should be set to 0.0.  It is generally desirable to set the value somewhat higher
       to allow for round-off error.

       The vector object is always black.

       Bdy()  is  part of the geomutil library; see geomutil(3) for information on how to link your program with
       this library.
