            plpath
          ( | n , | 
| x1 , | |
| y1 , | |
| x2 , | |
| y2 ); | 
      Joins the point 
        ( to
      x1,
        y1)
      
        (.  If a global coordinate transform
      is defined then the line is broken in to
      x2,
        y2)
      
         segments to approximate the
      path.  If no transform is defined then this simply acts like a call to
      n
      pljoin.
    
      Redacted form: plpath(n,x1,y1,x2,y2)
    
This function is used in example 22.
