This is an update to arcs.  I had posted some questions regarding arcs
several months ago, and promised to release the source when I am
finished.  Here is an update:

    - I finished an implementation, but there are some bugs which I hope
      I can get around to fixing sometime in the near future.
    - The implementation consists of

         * modification to the Painter and Graphic class
         * addition of 5 new classes under the Graphic class
           (Arc, Chord, Pie, FillChord, and FillPie)
         * addition of 3 new classes under the Selection class as found
           in IDraw. (I believe ArcSelection, ChordSelection and PieSelection)
         * additional support with rubber arcs.

    - Currently, the Postscript code is not implemented.
    - The current bug occurs on the rotation of the graphical arc classes.

I did manage to get the company to release the rights to the source code,
so I am able to release the work done.  I will be able to do so when I
can find the time to package it all together.  Also, I would like to
remove the blatant bug before releasing the code.

Several people e-mailed me expressing interest in the work done.  I was
meaning to reply to them, but I've accidentally erased the file with
your original messages.  To those people who sent me a message on this
subject, please contact me again.  Sorry for the inconvenience.
Also, anyone who would like to use arcs in Idraw, and is willing to
put up with the rotation bug, email me.  If there is enough demand, I
will try to package a pre-release package together, and place it in
the archives at Stanford for ftp users.

(Is putting source on the newsgroup acceptable?)

BTW, we are using InterViews version _2.6_.  If you are want to use arcs
& IV 3.0, you are on your own.
