Chipp wrote a nifty and very complete handler for determining if a
stack is visible to the user, named "isStackCurrentlyVisibleOnAnyMonitor".

The handler was discussed on the use-rev list, and Robert Brenstein
suggested perhaps it might make a good addition to stdLib.rev.

Robert's post with the full handler by Chipp is here:

Chipp has granted permission for its inclusion in stdLib.rev, but
before we do that I thought I'd run it past you folks here for an
informal vote: is this handler something you'd use often enough to
warrant inclusion in stdLib.rev?
