Note also that the current pcb has a checkbox to invert the polarity
of all the layers, so you can always print everything twice and pick
and choose which polarities you need.

At least, it's *supposed* to work that way.  If anyone has needed to
do that yet, they haven't reported back to us if it worked or not.
