Direction EAST or WEST apply also to ProjectedCRS and GeocentricCRS (the later
needs to be changed). Given the next step (add some amount), you may be better
to search for any axis where CoordinateSystemAxis.getRangeMeaning() returns
WARPAROUND, no matter the direction.

Better add CordinateSystemAxis.getMaximum() - getMinimum().

Spanning the antimeridian is a problem that I had in mind for a while and which
may have implications spreading in many places in the library. I didn't took
the
time to make a plan yet, so I don't really have a propal right now...
