Of course, happy to give more context. I primarily write graphic scores (but
with western notation symbols). The score isn't always static, so I want to be
able to manipulate fragments of music after generation.
In the past I have used my own program to place glyphs programmatically, which
requires that I create my own notation<>glyph mappings and to have the
engraving font installed/available to whoever views it.
When I saw that Lilypond produces shapes in SVG output, not glyphs, I was
intrigued--and leveraging Lilypond's input over my own mapping is appealing as
well.
I suppose one answer is keep my current system and outline the glyphs like
Lilypond may be doing under the hood. Another is to make and group selections
based on position, not an id attribute, from the current Lilypond output.
