+Subject: [PATCH 2/4] added fontconfig font search paths for OS X.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On OS X, fontconfig searches font only from /System/Library/Fonts, so this patch adds more search paths to its initialization.

+ FreeType-owned memory
 
 ass_strike_outline_glyph was realloc()ing memory that was
 allocated by FreeType, not us. This isn't generally safe.
