/* Base class for rectangle and ellipse item types.  These are defined by their top-left and
 * bottom-right corners.  Rectangles and ellipses share the following arguments:
 *
 * name			type		read/write	description
 * ------------------------------------------------------------------------------------------
 * 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
 * outline_color	string		W		X color specification for outline color,
 *							or NULL pointer for no color (transparent)
 * outline_color_gdk	GdkColor*	RW		Allocated GdkColor for outline
 * fill_stipple		GdkBitmap*	RW		Stipple pattern for fill
 * 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.
