|  | list of metamorphosis chains, each of which has its own fields:
 |  |  |  |  | defaultFlags |  |  | chain's default subfeature flags (UInt32)
 |  |  |  | featureEntries |  |  | list of feature entries, each of which has fields:
 |  |  |  |  | type |  |  |  |  |  |  | setting |  |  |  |  |  |  | enable |  |  |  |  |  |  | disable |  |  |  | 
 |  |  |  | subtables |  |  | list of metamorphosis subtables, each of which has fields:
 |  |  |  |  | type |  |  | subtable type (0: rearrangement; 1: contextual substitution; 2: ligature;
4: non-contextual substitution; 5: insertion)
 |  |  |  | direction |  |  | processing direction ('LR' or 'RL')
 |  |  |  | orientation |  |  | applies to text in which orientation ('VH', 'V', or 'H')
 |  |  |  | subFeatureFlags |  |  | the subfeature flags controlling whether the table is used (UInt32)
 | 
 Further fields depend on the type of subtable:
 | Rearrangement table:
 |  |  |  |  | classes |  |  | array of lists of glyphs
 |  |  |  | states |  |  | array of arrays of hashes{'nextState', 'flags'}
 | 
 Contextual substitution table:
 |  |  |  |  | classes |  |  | array of lists of glyphs
 |  |  |  | states |  |  | array of array of hashes{'nextState', 'flags', 'actions'}, where actionsis an array of two elements which are offsets to be added to [marked, current]
glyph to get index intomappings(orundefif no mapping to be applied) |  |  |  | mappings |  |  | list of glyph codes mapped to through the state table mappings
 | 
 Ligature table:
 Non-contextual substitution table:
 Insertion table:

 METHODS
$t->read
