A possible compression scheme

[Quentin Stafford-Fraser]

We've talked about this sort of caching scheme in the past, and agree it
could be a good idea.  One of the easiest ways might be for the server
to cache the last, say, 200 rectangles it has drawn, and then, when
drawing a new rectangle, to find out whether it might be a duplicate,
and use a CopyRect operation if so. Assuming, of course, that no
subsequent rectangle had overwritten it.  The big advantage of this
approach is that no changes to the protocol need to be made.

Anyone want to try it?
