[NTG-context] [OT] FreeType 2.4 now free from patent restrictions

http://sourceforge.net/projects/freetype/files/freetype2/2.4.0/NEWS/view I. IMPORTANT CHANGES - Since May 2010, all patents regarding the TrueType bytecode interpreter have expired worldwide. Consequently, we now define TT_CONFIG_OPTION_BYTECODE_INTERPRETER by default (and undefine TT_CONFIG_OPTION_UNPATENTED_HINTING). Formally a big step, practically most linux distro have bytecode interpreter enabled from long time. -- luigi
