Making it a command-line switch isn't necessary if it doesn't scale
until you try to zoom.  I think this is the correct way to handle it,
but as I said a window to tell you of the scaling would be nice.

One other problem: when zoomed out, tiles do not get updated properly
(for instance, when you move a unit diagonally).  Looks like this might
be happening because the original tiles are being used to draw instead
of the scaled ones.
