PangoGravityHint:
@PANGO_GRAVITY_HINT_NATURAL: scripts will take their natural gravity based
on the base gravity and the script. This is the default.
@PANGO_GRAVITY_HINT_STRONG: always use the base gravity set, regardless of
the script.
@PANGO_GRAVITY_HINT_LINE: for scripts not in their natural direction (eg.
Latin in East gravity), choose per-script gravity such that every script
respects the line progression. This means, Latin and Arabic will take
opposite gravities and both flow top-to-bottom for example.
The #PangoGravityHint defines how horizontal scripts should behave in a
vertical context. That is, English excerpt in a vertical paragraph for
example.
