/* Base class for rectangle and ellipse item types.  These are defined by their top-left and

 * ------------------------------------------------------------------------------------------
 * 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)

 * 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.
