In FreeType 2.7, Infinality support is now handled by

  /* Define TT_CONFIG_OPTION_SUBPIXEL_HINTING if you want to compile       */
  /* subpixel hinting support into the TrueType driver.  This modifies the */
  /* TrueType hinting mechanism when anything but FT_RENDER_MODE_MONO is   */
  /* requested.                                                            */
  /*                                                                       */
  /* In particular, it modifies the bytecode interpreter to interpret (or  */
  /* not) instructions in a certain way so that all TrueType fonts look    */
  /* like they do in a Windows ClearType (DirectWrite) environment.  See   */
  /* [1] for a technical overview on what this means.  See `ttinterp.h'    */
  /* for more details on the LEAN option.                                  */
  /*                                                                       */
  /* There are three options.                                              */
  /*                                                                       */
  /* 1. This option is associated with the `Infinality' moniker.           */
  /*    Contributed by an individual nicknamed Infinality with the goal of */
  /*    making TrueType fonts render better than on Windows.  A high       */
  /*    amount of configurability and flexibility, down to rules for       */
  /*    single glyphs in fonts, but also very slow.  Its experimental and  */
  /*    slow nature and the original developer losing interest meant that  */
  /*    this option was never enabled in default builds.                   */
  /*                                                                       */
  /* 2. The new default mode for the TrueType driver.  The Infinality code */
  /*    base was stripped to the bare minimum and all configurability      */
  /*    removed in the name of speed and simplicity.  The configurability  */
  /*    was mainly aimed at legacy fonts like Arial, Times New Roman, or   */
  /*    Courier.  Legacy fonts are fonts that modify vertical stems to     */
  /*    achieve clean black-and-white bitmaps.  The new mode focuses on    */
  /*    applying a minimal set of rules to all fonts indiscriminately so   */
  /*    that modern and web fonts render well while legacy fonts render    */
  /*    okay.                                                              */
  /*                                                                       */
  /* 3. Compile both.                                                      */
