Yes, you get small files, BUT: If I compile LilyPond out of the box
using GS version 9.56.1 or 10.0.0 together with `extractpdfmark`, I
get PDF files with many hyperlinks gone. I've just tried compilation
again with current git: `notation.pdf` is about 6MByte and doesn't
contain any internal links: just try the table of contents. For me,
this looks like the PDF interpreter ignoring `notation.pdfmark`.
Jonas, how do you compile? Do you get something better?
