Re: Allow use of Identity-H CMap and CID versions of Emmentaler (issue 343970043 by address@hidden)

[knupero]

Changes:

Command line:
"-O size"  is gone
"-O legacy" is added, uses our old non-encodings code
"-O TeX" new default as the pdf files are smaller.
"-O TeX-GS" use if you want to include lilypond pdfs in TeX document and
postprocess the resulting pdfs with ghostscript. You also need to give
/path/cidres.ps to gs.

If you use -dsafe also use -O legacy. I hope I'll fix that soon.

BTW: -dsafe on windows system is broken since 2005. Don't rely on it.

Not only fonts, but also most of our ps files are loaded by gs if -O
TeX* is given.

-dmusic-font-encodings is gone as the code has been ripped out.
-duse-cid-fonts is implemented.

-O legacy/TeX/TeX-GS set gs_load_font, gs-never-embed-fonts,
use-cid-fonts to the appropriate values, you never need to use those
parameters directly


The minimal lilypond source file t

   \score { c''' }

translated with 'lilypond -O legacy --ps --pdf t.ly ; dir t.ps t.pdf;
pdffonts t.pdf' gives:
