I'm trying to define a character in a user-defined font that consists of
characters from a builtin font.  Specifically, I would like the INTERACTIVE
logo to be produced by \(bs from troff.  The logo consists of the word
INTERACTIVE in Helvetica, a row of filled boxes below that, and the words
"A Kodak Company", also in Helvetica (Kodak is in Helvetica-Bold), below
that.  I have a PostScript procedure that produces the logo which works
fine by itself but only partially works when executed as the procedure
defining a particular character in a user-defined font.  I seem to get
different wacky behavior depending on the size of the logo.  For example,
one particular size (26) produces the logo but has the annoying side effect
of producing a little mark at the very top of the page, the position
apparently not depending on the position of the logo.  After a little
experimentation, I discovered that the little mark is apparently the very
bottom of the "C" in INTERACTIVE (changing the C to an X causes the mark to
go away).  Any ideas?
