Oops, sorry about that.  Yeah, you can't just resize pngs in gimp
without changing the mode to RGB first.  Another reason to do that
step inside pcb; gd has an RGB format but I don't think older gd's
support it, it would have to be tested for.

IMHO "as shown" will almost always get too close to the parts, closer
than any real board.  The intent with that was to use it to produce
figures for documentation, where you only want to see the
element/copper/via/whatever and there won't be any borders around it
anyway.

For a real outline, we need to consider a non-rectangular outline -
gather up segments, match them into polygons, fill them with opaque,
etc.
