-   *   The function @FT_Get_Gasp can be used to query a TrueType or OpenType
-   *   font for specific entries in its `gasp' table, if any.  This is

-   *
-   * @description:
-   *   A list of values and/or bit-flags returned by the @FT_Get_Gasp
-   *   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.
