One recent message implied that Xerox Viewpoint is the 1981 Star
product simply renamed.  Not true.  As delivered, Viewpoint provides
generally the same functionality, but it is noticeably faster, a good
deal of the interface has been changed (e.g. overlapping windows in
arbitrary positions are allowed now), and quite importantly, it has
been unbundled.  Star was a monolithic program, but Viewpoint is a
bunch of modules.  Using the XDE system, one can write one's own
modules and load them into Viewpoint.  This is clearly important to
allow 3rd-party developers to add to Viewpoint.
