Line

class Line extends DJComponent {
      dj int x1;
      dj int y1;
      dj int x2;
      dj int y2; 
      x <= x1; x <= x2;
      y <= y1; y <= y2;
      x1 <= x+width; x2 <= x+width;
      y1 <= y+height; y2 <= y+height;
}
  A line is specified by two points: (x1,y1) and (x2,y2). The constraints ensure that the line lies inside the layout area for the line.
