- off: no kerning.
- fast: use FreeType's kerning implementation (no ligatures).
- enhanced: use HarfBuzz's kerning implementation (slower, but may support ligatures with some fonts).
- good: use HarfBuzz's light kerning implementation (faster than full but no ligatures and limited support for non-western scripts)
- best: use HarfBuzz's full kerning implementation (slower, but may support ligatures with some fonts).
(Font Hinting may need to be adjusted for the best result with either kerning implementation.)]]),
