I think I've addressed all these issues with my patch.  See my
response to Daniel elsewhere in this thread.

I suppose this could be done with a button matrix located somewhere
near the map...

I think the reason he wanted this is because the original scrollbars
would move the map at a 45 degree angle relative to the scrollbar
direction, which is not at all intuitive.  But I'll let him speak for
himself.  :-)

Actually, I rather like his solution.  Wonder if there's a way we
could make this into a runtime option or something...

    It's really hard to define what "unexpected behavior" means when you're
                       talking about Windows.
