      This sets up the line style for all lines subsequently drawn.  A line
      consists of segments in which the pen is alternately down and up.
      The lengths of these segments are passed in the vectors

nms
          (PLINT
            The number of 
              
            and mark
            
               elements in
            a line.  Thus a simple broken line can be obtained by setting
            space
            
              .  A continuous
            line is specified by setting
            nms=1
            
              .
          nms=0
            
mark
          (PLINT_VECTORA vector containing the lengths of the segments during which the pen is down, measured in micrometers.
space
          (PLINT_VECTORA vector containing the lengths of the segments during which the pen is up, measured in micrometers.
