Problem: so far, these names have not been conveyed.
But after the net IDs changed in the LVS DB (renumbering),
the names should be retained. Otherwise it is difficult to
relate log level entries or Spice netlists to them.
The solution is to drop clusters that have no area
and not connections downward. This implies, we cannot
connect from upward to such clusters - i.e. we cannot
force a pin inside a subcircuit with a plain text. We
need some polygon at least. This is not a problem as
texts were not enough so far anyway.
