/* Polygon item for the canvas.  A polygon is a bit different from rectangles and ellipses in that
 * points inside it will always be considered "inside", even if the fill color is not set.  If you
 * want to have a hollow polygon, use a line item instead.
 *
 * The following object arguments are available:
 *
 * name         type            read/write  description
 * ------------------------------------------------------------------------------------------
 * points       GnomeCanvasPoints*  RW      Pointer to a GnomeCanvasPoints structure.
 *                              This can be created by a call to
 *                              gnome_canvas_points_new() (in gnome-canvas-util.h).
 *                              X coordinates are in the even indices of the
 *                              points->coords array, Y coordinates are in
 *                              the odd indices.
