Works for me.
I noted one additional bug: you have to condition whether to dump
the upper coordinates just on the IS_POINT flag, because that is
all that cube_recv will see. The cube_is_point_internal() hack
can be used in some other places, but not here.
Also, as a matter of style, I didn't like that cube_send was using
the LL_COORD/UR_COORD abstraction but cube_recv wasn't. In the
worst case (if someone tried to change that abstraction) this could
turn into an actual bug, with cube_recv storing the coordinates in
the wrong order. Could have gone either way on which one to change
to look like the other, but I chose to simplify cube_send to look
like cube_recv. This essentially means that we're locking the
binary representation to use the physical storage order of the
coordinates even if someone gets fancy about their meaning.
Pushed with those fixes.
