NAME
    Font::TTF::GrFeat - Graphite Font Features

DESCRIPTION
INSTANCE VARIABLES
    version
    features
        An array of hashes of the following form

        feature feature id number

        name    name index in name table

        exclusive
                exclusive flag

        default the default setting number

        settings
                hash of setting number against name string index

METHODS
  $t->read
    Reads the features from the TTF file into memory

  $t->out($fh)
    Writes the features to a TTF file

  $t->minsize()
    Returns the minimum size this table can be. If it is smaller than this, then the table must be
    bad and should be deleted or whatever.

  $t->print($fh)
    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.

BUGS
    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.
