Hi David,
good you figured it out. As I'm doing this stuff frequently, here are
some remarks, maybe it's useful for you:

If I'm not mistaken, the name "Postsript" is actually related to the
fact, that it is a postfix programming language ;-) There are lots of
tutorials on Postscript in the net and I'd recommend reading some of
them and learning the basics. Postscript is turing complete and
therefore a very powerful programming language.
If you insert "<x> <y> scale" or "<x> <y> translate" somewhere into
your postscript code, all drawing afterwards will be scaled or
translated accordingly. That might save you some number editing using
spreadsheets. In Postscript you can also create macro-like
definitions, build dictionaries and such. If you use emacs as a text
editor, you can explore postscript in a very similar fashion as
lilypond out of the box: Type the code in a text window and evaluate
it to see the graphics shown in another window.
When I design custom clefs or symbols for lilypond, I normally start
by using inkscape (https://www.inkscape.org) for importing, drawing
and exporting to ps or eps format and then open it in emacs and
adjust/reduce the code.
HTH,
Orm
