[José Roca]

The following example creates a GraphicsPath object path and adds two figures to path. The code closes the first figure, but leaves the second figure open.

   path.AddArc(rect1, 0.0f, 180.0f);  // first figure
   path.CloseFigure();                // first figure closed
   path.AddArc(rect2, 0.0f, 180.0f);  // second figure

   // Draw the path.
   Pen pen(Color(255, 255, 0, 0));
   graphics.DrawPath(&pen, &path);
