A box is a rectangle with a specified width and height. The default
width and height are the values of the "boxwid" and "boxht" variables.

If a "radius" is specified, then the corners of the box are rounded using
arcs of the given radius. The default radius for each new box is the value
of the "boxrad" variable which is initially 0.0.
