I guess we could use refelem.center(0) as the test-coordinate instead of (1,
1, 1).  That should definitely be inside, and should cover all corner-cases at
least as good as the coordinate we're currently using (read: nearly non of
them).  Except that it does not test outside the element, of course.

Has anyone objections to that?

Regards,
Jö.
