Synopsis:
    #include <graph.h>
    short _FAR _rectangle( short fill,
                           short x1, short y1,
                           short x2, short y2 );

    short _FAR _rectangle_w( short fill,
                             double x1, double y1,
                             double x2, double y2 );

    short _FAR _rectangle_wxy( short fill,
                               struct _wxycoord _FAR *p1,
                               struct _wxycoord _FAR *p2 );

Description:
    The _rectangle functions draw rectangles.  The _rectangle function uses
    the view coordinate system.  The _rectangle_w and _rectangle_wxy
    functions use the window coordinate system.

    The rectangle is defined with opposite corners established by the points
    (x1,y1) and (x2,y2).

    The argument fill determines whether the rectangle is filled in or has
    only its outline drawn.  The argument can have one of two values:

    _GFILLINTERIOR
        fill the interior by writing pixels with the current plot action
        using the current color and the current fill mask

    _GBORDER
        leave the interior unchanged; draw the outline of the figure with
        the current plot action using the current color and line style


Returns:
    The _rectangle functions return a non-zero value when the rectangle was
    successfully drawn; otherwise, zero is returned.

Example:
    #include <conio.h>
    #include <graph.h>

    main()
    {
        _setvideomode( _VRES16COLOR );
        _rectangle( _GBORDER, 100, 100, 540, 380 );
        getch();
        _setvideomode( _DEFAULTMODE );
    }

    produces the following:
