        I'm using the Eiffel graphics library and wonder if anyone has
a class or classes that describes arcs.  The ISE library contains class
ELLIPSE and class CIRCLE, but I need to draw circular and elliptical arcs.
When I started using Eiffel, I wrote a class for circular arcs that simply
built a polyline, but it is slow.  I am about to write a new class for arcs 
that utilizes the Xlib routines for drawing arcs, but thought I would see if
anyone has already done this and is willing to share.
