       Font::TTF::GrFeat - Graphite Font Features

	   An array of hashes of the following form

	   feature feature id number

	   name    name index in name table

		   exclusive flag

	   default the default setting number

		   hash of setting number against name string index

       Reads the features from the TTF file into memory

       Writes the features to a TTF file

       Prints a human-readable representation of the table

   $t->tag_to_num ($feat_str)
       Convert an alphanumeric feature id tag (string) to a number (32-bit).  Tags are normally 4
       chars. Graphite ignores space padding if it is present, so we do the same here.

   $t->num_to_tag ($feat_num)
       Convert a feature id number (32-bit) back to a tag (string).  Trailing space or null
       padding is removed.  Feature id numbers that do not represent alphanumeric tags are
       returned unchanged.

       The version 1 Feat table ends with a feature (id 1) named NoName with zero settings but
       with an offset to the last entry in the setting array. This last setting has id 0 and an
       invalid name id. This last feature is changed to have one setting.
