polygon operators (<<, &<, >>, &>).  Per ideas originally put forward
by andrew@supernews and later rediscovered by moi.  This patch just
fixes the existing opclasses, and does not add any new behavior as I
proposed earlier; that can be sorted out later.  In principle this
could be back-patched, since it changes only search behavior and not
system catalog entries nor rtree index contents.  I'm not currently
planning to do that, though, since I think it could use more testing.
