Nevertheless, that is what QD does.  Actually, QD uses a rectangular pen.
The inset-oval method is because it would look even worse if QD did what it
does for polygons, where the pen hangs down and to the right.  At least, by
filling the pen pattern between two ovals, the framing is entirely inside
the outer oval.
