as long as the command is not attempting to modify the port.
Attempts to modify ports in non-edit cells result in an error
message that is more helpful than the previous "Exactly one label
must be present..." text.
since the edit box was undefined in the code, potentially this
fixes any number of random problems that might be seen with the
"port" command. Also: Modified the cell bounding box recalculation
so that it does not continually update a parent cell on every
addition of a child cell but only once for each child cell found.
This greatly reduces the time for GDS file input in the case of
large arrays of cells.
a port so that repeated uses of "apply" won't fail because the
port number is already used. Corrected the "port remove" command,
which didn't work, and corrected the script to do "port exists"
before "port index" so that the latter won't complain if the label
is not a port. Same changes made to magic-8.1.
avoid the problem where subcells violate DRC themselves but do
not violate DRC in the context of the parent (i.e., the parent
adds metal to avoid minimum area error), DRC errors in subcells
are neither counted nor displayed, but they remain present in
the subcell database. The DRC check enumerates all subcell
errors as mandatory check areas in DRCFindInteractions(), so
that those areas are always counted with the interaction areas.
Previously, if a subcell violated a DRC rule by itself, that
error would be counted and displayed in the parent even if the
parent had paint causing the error to no longer exist.
