DRC doesn't detect overlapping components

I created a board that has overlapping components,
where multiple pins share the same location. There
are some very good reasons to do this sometimes, but
often it is
an error. No netlist was loaded.

DRC passed the board with flying colors, except for
some complaints about traces to close to square pins.

DRC behavior in this situation should be configurable
on a board by board basis. When you actually want
to do this, you don't want a hundred errors but
you also don't want it to silently overlook components
that have been accidently superimposed.
