 * ------------------------------------------------------------------------------------------
 * x1             double            RW          Leftmost coordinate of rectangle or ellipse
 * y1             double            RW          Topmost coordinate of rectangle or ellipse
 * x2             double            RW          Rightmost coordinate of rectangle or ellipse
 * y2             double            RW          Bottommost coordinate of rectangle or ellipse
 * fill_color           string            W           X color specification for fill color,
 *                                        or NULL pointer for no color (transparent)
 * fill_color_gdk GdkColor*   RW          Allocated GdkColor for fill

 *                                        or NULL pointer for no color (transparent)
 * outline_color_gdk    GdkColor*   RW          Allocated GdkColor for outline

 * outline_stipple      GdkBitmap*  RW          Stipple pattern for outline
 * width_pixels         uint        RW          Width of the outline in pixels.  The outline will
 *                                        not be scaled when the canvas zoom factor is changed.
 * width_units          double            RW          Width of the outline in canvas units.  The outline
 *                                        will be scaled when the canvas zoom factor is changed.
