Subject: Fix preview of lilypond (book) snippets (#13103)
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=770362da97d28385bc3974891bf22d0fcb19be90;p=lyx.git

Fix preview of lilypond (book) snippets (#13103)

1. The --safe option has been removed with lilypond 2.24 and causes
   the program to error out
2. We default to PDF output (and pdflatex) if no program is explicitly
   given, since latex generates *.eps snippets which fail to convert
   on many recent systems due to security measures
