If you force the mapsize or its aspect ratio to be twice
as wide as it is tall (500 x 250) then it will do its best
to fit the requested map into that space. if you experiment
with always defining regions that are this shape, the request
will work fine. The mapserver will never distort the coordinates
to display within a specified mapsize, it will align with the
smaller extent dimension and show more in the other dimension.
