✅ TODO

• Allow morphing multiple words in one go
• Allow morphing words with different lengths
  • Possibly using edit distance algorithms, but might need to favor substitutions over insertions/deletions
• Option for enabling/disabling word matching
  • Say we want to morph "banana" to "orange"
  • When word matching is enabled, xbanana will not be morphed, because we're matching whole words, not letters
  • When word matching is disabled, xbanana will be morphed to xorange
• Optimization
  • Use CoverageTable::Format2, which allows for more efficient storage of contiguous ranges of glyphs
• Better word matching
  • Currently we consider whole words only by letters ([a-zA-Z]+)
  • Next stage: consider digits ([0-9]+) and underscores (_)
  • Maybe an option for toggling which characters to consider as part of words?
• Bug fixes
  • Might not work with fonts with multiple language records, e.g. IMPACT.TTF
