flipped region

[Simon Cox]

Could it be due to the fact that the 180W or 180E longitude
falls in the middle of your region.  Grass is probably displaying
the whole world from -180 -> +180, and then balnking out the
(Main) bit in the MIDDLE which isn't in your region!

Sounds like a bug in the way Grass handles Lat-Long - it
probably uses a bounded Cartesian universe, rather than
a spherical, cylindrical or toroidal system.  You may have
to use two regions either side of the join unless someone
fixes this!
