Adjusting staff size and changing fonts

[Matthias Böhringer]

Hello all,

I am currently using lilypond 2.10.13 in Win XP, just in case this
should matter.

I'm trying to use other fonts than the default. I was partly
successful, as I discovered the "define fonts" command. However, I
could not find, where this command is documented in the lilypond
documentation.

Example: #(define fonts
        (make-pango-font-tree 
        "Savoy-Osf" 
        "LucidaSans" 
        "LucidaTypewriter"
        (/ 20 20)))

What exactly does the last line do?

Can anyone point me in the right direction?

In the same vein, I tried to change fonts and at the same time to
adjust the staff size. However, using "set-global-staff-size" (or
"layout-set-staff-size") seems to always revert my font selection to
the default font.

What do I need to do to adjust the staff size and keep my selected
fonts?

Any hints, where this is documented?

Liebe Grüße, Matthias
