* Harfbuzz landed! {{bug|449292}}
** It's turned off by default. To turn it on:
*** Set gfx.font_rendering.harfbuzz.level to 1; harfbuzz will be used for"simple" scripts (Latin, Cyrillic, CJK) that do not require specific complexshaping.
*** You can set it to 2; Harfbuzz will then be used for all scripts (even though the results will currently be broken).
