I want to thank der Mouse and the others who responded to this post.  The
general approach seemed to be:

    o Query the R5 server ("getbdf" can come into play here) to get a
      BDF file to use as a boilerplate.

    o Tweak the BDF file as necessary to "pretty up" the glyphs.  Tune
      the BDF/XLFD parameters as needed.

    o Compile the BDF file [using bdftosnf(1) or bdftopcf(1) for example].

    o Install the compiled result as per the FAQ, subject #39, on the R4
      server.

Let me add a few clarifications to the approach.

Rather than starting an R5 server, I used "getbdf" to obtain BDF files
from my R4 server.  Mark Martin (mmm@cetia.fr) provided me a useful shell
script to double the size of a BDF file; it handles the BITMAPs and the
BDF/XLFD parameters quite nicely.  Thanks, Mark.

Clean up of the glyphs was accomplished via "xfed" (export.lcs.mit.edu in
/pub/R5untarred/contrib/clients).  This is somewhat tedious but very
strightforward.  "xfed" works like the R4 bitmap(1) client only directly
against BDF files.

Compiling and installing were no problem on my SGI Personal Iris.  The
directory containing the compiled fonts is a target for mkfontdir(1).
Then, you add the directory to the server font path via xset fp+ <$dir>.
See the FAQ for more on this.

I'll end with a hypothetical question on this subject.  Say you were to
choose one of the commercial fonts in X (adobe, sony, b&h, etc.) and
scale it up - double size, quadruple size, whatever.  What are the legal
implications of including the scaled font as part of an X client of
your own?  I'm speculating the original copyright must stay in place
in the font.  But what if you surgically alter the bitmaps (via "xfed"
or whatever you like).  What happens to the copyright then?  Thoughts
and comments anyone?
