I just realized that pcb's default library actually has different sets
of footprints for chip capacitors and chip resistors.  For example,
these are the "imperial 0603" footprints:

Chip capacitors: CAPC1608L/N/M
Inductors (appears identical to CAPC footprint): INDC1608L/N/M
Resistor: RESC1608L/N/M

The CAPC/INDC footprints appear to have larger pads than the RESC
footprints.
