   *   function.
   *
   * @values:
   *   FT_GASP_NO_TABLE ::
   *     This special value means that there is no GASP table in this face.
   *     It is up to the client to decide what to do.
   *
   *   FT_GASP_DO_GRIDFIT ::
   *     Grid-fitting and hinting should be performed at the specified ppem.
   *     This *really* means TrueType bytecode interpretation.  If this bit
   *     is not set, no hinting gets applied.
   *
   *   FT_GASP_DO_GRAY ::
   *     Anti-aliased rendering should be performed at the specified ppem.
   *     If not set, do monochrome rendering.
   *
   *   FT_GASP_SYMMETRIC_SMOOTHING ::
   *     If set, smoothing along multiple axes must be used with ClearType.
   *
   *   FT_GASP_SYMMETRIC_GRIDFIT ::
   *     Grid-fitting must be used with ClearType's symmetric smoothing.
   *
   * @note:
   *   The bit-flags `FT_GASP_DO_GRIDFIT' and `FT_GASP_DO_GRAY' are to be
   *   used for standard font rasterization only.  Independently of that,
   *   `FT_GASP_SYMMETRIC_SMOOTHING' and `FT_GASP_SYMMETRIC_GRIDFIT' are to
   *   be used if ClearType is enabled (and `FT_GASP_DO_GRIDFIT' and
   *   `FT_GASP_DO_GRAY' are consequently ignored).
   *
   *   `ClearType' is Microsoft's implementation of LCD rendering, partly
   *   protected by patents.
