OK did some investigation. I had blown away the old version
so I downloaded 0.92 and looked at that. Version 0.92 didn't
have right-mouse pan but clicks of the mouse would pan it in
steps so its dificult to compare. I looked at 0.95 release 7
on an Athlon 500MHz and its got no rubber band but Alpha
550MHz has. Perhaps it has more to do with the video card,
vid mem, and version of XFree than with clock speed though. 

Its most noticable on the Alpha when I pan quickly over a
large distance. Dragging with the right-mouse button slowly
its not really noticable. If I pan quickly when I stop the
mouse the cave will overshot and inch.

Its not a show-stopper in any way and its minor so you don't
need to spend any significant time on it. I just notice it
as its the ONLY graphic app that does show any delay at all
on the Alpha.

PS. doxygen looks pretty good. Very important that its GPL
and that your source code stays usable as you dont won't to
get locked into something that you can't back out of later.
I just saw yesterday a source code documentation product
that links your code via Windows OLE's into Word for
documentation :-)
