     Huh? If you mill down the center of the trace you remove the copper
     there and get a negative of what you want. Did I miss something?

   You would have to use a layer as a "milling" layer and then you could
   draw arbitrary holes and slots.  I don't know that doing this from the
   gcode exporter is possible yet, but parsing it from an exported gerber
   file is not to bad.
