14           list of metamorphosis chains, each of which has its own fields:
15
16           defaultFlags
17               chain's default subfeature flags (UInt32)
18
19           featureEntries
20               list of feature entries, each of which has fields:
21
22               type
23               setting
24               enable

29               type
30                   subtable type (0: rearrangement; 1: contextual
31                   substitution; 2: ligature; 4: non-contextual substitution;
32                   5: insertion)
33
34               direction

41                   the subfeature flags controlling whether the table is used

43
44               Further fields depend on the type of subtable:
45
46                   Rearrangement table:
47
48                   classes
49                       array of lists of glyphs
50
51                   states
52                       array of arrays of hashes{'nextState', 'flags'}
53
54                   Contextual substitution table:
55
56                   classes
57                       array of lists of glyphs
58
59                   states
60                       array of array of hashes{'nextState', 'flags',
61                       'actions'}, where "actions" is an array of two elements
62                       which are offsets to be added to [marked, current]
63                       glyph to get index into "mappings" (or "undef" if no
64                       mapping to be applied)
65
66                   mappings
67                       list of glyph codes mapped to through the state table
68                       mappings
69
70                   Ligature table:
71
72                   Non-contextual substitution table:
73
74                   Insertion table:
