Too much info is floating around, so here is a table that shows the
various possibilities we are currently investigating.
* Everything is based on commit 056784fcb9.
* All eight compilations were started from scratch using LuaTeX;
`notation.pdf` was produced by `make bytecode; make doc`.
* To produce Cairo output I used
`make doc ... LOCAL_LILYPOND_FLAGS="-dbackend=cairo"`.
* For the `-dNEWPDF=false` and `-dPreserveMarkedContent` builds I used
the attached patches, which are mutually exclusive.

[1] The next GS version (appearing in March 2023) will no longer
contain the old PDF engine.
[2] This is a self-compiled version 10.0.0 with a very small patch
(already in the GS repository) that enables
`-dPreserveMarkedContent`.
