Hello,
on Windows 10 with LilyPond 2.23.35 I noticed a problem:
lilypond-book-preamble.ly doesn't produce an auto-cropped image.
The following snippet
% -------------------------------------
\include "lilypond-book-preamble.ly"
{c}
% -------------------------------------
should result in small image with no margins around the staff.
Instead, I get a DIN A4 sized image (only with tagline temoved and top
margin set to zero).
With 2.23.4, 2.23.3 and 2.22.1 the result still is as expected.
Cheers,
Klaus
