[tex-k] note from Don Knuth -- bug(s) in MetaPost?

PS -- The "unfilled circles" happen when Ghostview or Preview renders
that PostScript file. But if you apply Acrobat Distiller, and presumably
also if you use a reputable Adobe "rip" to create the image, all of
the circles are filled in.

Some of them are however larger than others, because of the "stroke"
in addition to "fill", and that should not be.

Unfortunately the Ubuntu engine that converts PostScript to my
laserprinter has the same bug as Preview and Ghostview...
