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.
