When rendering contained cells, my implementation uses a temporary list
of cells already part of the containment structure and never follows a
connection that leads to a cell already included earlier.  This allows
arbitrary depths without looping, but of course it is only one possible
implementation; there could be situations in which looping to a fixed
depth is preferable.
