OK, that's confusing since the exported gerber for 'paste' is drawn
in positive, where 'paste' is displayed.  It would be awesome if
there was a way to merge both additive and subtractive edits with a
layer.  Maybe that's too much work, perhaps it's the 90/10 rule and
your implementation already covers 90% of uses.
