/**************************************************************************
   *
   * This file is used to define the FreeType module error codes.
   *
   * If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
   * set, the lower byte of an error value identifies the error code as
   * usual.  In addition, the higher byte identifies the module.  For
   * example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
   * error `TT_Err_Invalid_File_Format` has value 0x1303, the error
   * `T1_Err_Invalid_File_Format` has value 0x1403, etc.
   *
   * Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
   * including the high byte.
   *
   * If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
   * error value is set to zero.
   *
   * To hide the various `XXX_Err_` prefixes in the source code, FreeType
   * provides some macros in `fttypes.h`.
   *
   *   FT_ERR( err )
   *
   *     Add current error module prefix (as defined with the `FT_ERR_PREFIX`
   *     macro) to `err`.  For example, in the BDF module the line
   *
   *     ```
   *       error = FT_ERR( Invalid_Outline );
   *     ```
   *
   *     expands to
   *
   *     ```
   *       error = BDF_Err_Invalid_Outline;
   *     ```
   *
   *     For simplicity, you can always use `FT_Err_Ok` directly instead of
   *     `FT_ERR( Ok )`.
   *
   *   FT_ERR_EQ( errcode, err )
   *   FT_ERR_NEQ( errcode, err )
   *
   *     Compare error code `errcode` with the error `err` for equality and
   *     inequality, respectively.  Example:
   *
   *     ```
   *       if ( FT_ERR_EQ( error, Invalid_Outline ) )
   *         ...
   *     ```
   *
   *     Using this macro you don't have to think about error prefixes.  Of
   *     course, if module errors are not active, the above example is the
   *     same as
   *
   *     ```
   *       if ( error == FT_Err_Invalid_Outline )
   *         ...
   *     ```
   *
   *   FT_ERROR_BASE( errcode )
   *   FT_ERROR_MODULE( errcode )
   *
   *     Get base error and module error code, respectively.
   *
   * It can also be used to create a module error message table easily with
   * something like
   *
   * ```
   *   #undef FTMODERR_H_
   *   #define FT_MODERRDEF( e, v, s )  { FT_Mod_Err_ ## e, s },
   *   #define FT_MODERR_START_LIST     {
   *   #define FT_MODERR_END_LIST       { 0, 0 } };
   *
   *   const struct
   *   {
   *     int          mod_err_offset;
   *     const char*  mod_err_msg
   *   } ft_mod_errors[] =
   *
   *   #include <freetype/ftmoderr.h>
   * ```
   *
