obviously... it means that:
- PS, SVG and PDF output is correct (i.e. you have a 'donut' pad)
- In HPGL you can't see them
- In gerbers you can't see them, too. This is arguably the right thing to
do since having drill marks and high speed drill stations is a sure
recipe for broken tools and angry manufacturers. If you *really* want them
you could start a layer with negative polarity to scrape the film.
- In DXF they go into the 'WHITE' layer. This could be useful.
