We are starting to use the Hershey fonts for graphic symbols, some of
which need to be defined as having zero width, and starting at a particular
offset from the natural "character" starting place.  The Hershey fonts
contain not only the vectors defining the characters, but also quite a
few extra digits that code stuff like maximum x offset in each direction
and so forth.  Does anyone have a description of what all the code digits
mean?

A probably related problem is that since we went to V7 a few years ago on
our PDP-11, and remade the fonts, continuous underbars (eg in tbl) come out
dashed, large braces don't line up their segments properly -- nor do other
built-up characters, -- and there are other little bugs with the correct
relative locations of things.  If this isn't the same problem as above,
has anyone encountered and/or solved this?
