[MPlayer-cvslog] r28276 - in trunk/libvo: font_load.h font_load_ft.c

[eugeni]

New Revision: 28276

Log:
Support loading font faces other then the first one in a font file.

With -fontconfig, it is possible to select a face with index higher than
0 in a multi-face font file. Currently, with the old rendering code,
this information is lost and the first face is loaded. With this change,
index supplied by fontconfig is used for font loading.
