mpv/libmenu/vf_menu.c
arpi c8b0ddfe4e these patches let ,,oldstyle'' and freetype subtitle renderers live
together happily. if an oldstyle subtitle (font.desc) is found, it will
be used. otherwise mplayer will choose subfont.ttf, if freetype was
detected during ./configure.
(also you can use -font /path/to/font.desc and -font /path/to/foobar.ttf too)
