Have you actually read the MetaFog paper by Richard Kinch? Parsing the
file is not the problem. The problem is determining the outline of a
stroked, self-overlapping drawing. That involves some nasty
mathematics. And the feta font definitely uses penstrokes and overlaps.

there is not much, but I'd like to expand in that direction: we have a
blot-diameter, that should cause the smaller glyphs to be a little
chubbier. It is not used by many glyphs, though.
