I actually don't know how the original set of flags were done. Someone,
maybe Bill Cheswick, grabbed them somewhere as 1-bit images.
Later, John Hobby, in a fit of creativity, noticed that each stipple
pattern represented a different color and processed them so they'd
look good on our color displays.  I've added a couple of flags by
grubbing on the net and then processing.  If you can find a gif
or jpg, you can convert it.  I have a resampler, based on the one
in the second edition, you can use to reduce the image, but it's
buggy so I didn't include it.  (The bugs were in the 2nd edition too
- it goes beyond the ends of arrays and produces black borders
or crashes.)  I'll get back to it one day.
