It is also possible to have a rectangle in UTM space contain points that
are NOT inside the quadrilateral formed by connecting the four
reprojected corner points into lat/lon space.  Conversely, there can be
points inside that lat/lon quadrilateral that were NOT inside the UTM
rectangle.  You might need to keep that in mind depending on how fussy
your application is.

Actually now that I think about it it makes sense.
If it is square in UTM... It will be rotated somewhat.

So nix that last comment.
