What is the correct thing to look for, then?  The mask layers I got
have, in gerbv, grey where there should be soldermask and black where
there should be no soldermask.  The silk layer has grey where there
should be ink, and black where there should be no ink.  The copper
layer has black where there should be no copper and grey where there
should be copper.

I assumed from what pcbexpress told me that they were complaining
about the use of ``IPNEG'' in the gerber file for the solder mask
layers, but I'm not sure.

I'm not sure if that would get me the optimal pad size, though.  Also,
doing that manually for 9 connectors times three holes per connector
would leave me feeling like I'd like better automation.
