One more thought -- you should be able to turn off the antialiased
property, eg with

  plot(x, y, antialiased=False)

Unfortunately, I poked into our backend_pdf and it appears this
property is ignored.  Jouni: is there a way to turn off antialiasing
in PDF, and could we add support for this in the backend?
