   *    Validate various OpenType tables to assure that all offsets and

   *    checking (which can be quite time consuming).

   *    validation_flags ::
   *      A bit field that specifies the tables to be validated.  See
   *      @FT_VALIDATE_OTXXX for possible values.
   *
   * @output:
   *    BASE_table ::
   *      A pointer to the BASE table.
   *
   *    GDEF_table ::
   *      A pointer to the GDEF table.

   *
   * @note:
   *   This function only works with OpenType fonts, returning an error
   *   otherwise.
   *
   *   After use, the application should deallocate the five tables with
   *   @FT_OpenType_Free.  A `NULL` value indicates that the table either
   *   doesn't exist in the font, or the application hasn't asked for
