Well, right now I'm rewriting the parmesan stuff to make it work with
mf2pt1 (the feta stuff has already be done two years ago). After this
has been finished, only `fill' and `unfill' is used, and `draw' and
`drawdot' are gone.

I was thinking of doing something similar directly in metafont:
1. Collect all paths within a glyph so that they can be addressed
sequentially.
2. Find intersections of horizontal rays coming from the left with
all paths, taking the minimum x value of the found intersections.
The vertical distance of those rays (which gives the resolution
granularity) is something I would like to know from you.
3. Repeat step 2 for the remaining three directions.
