PangoDirection
enumeration PangoDirection defined in Gnome::Pango::T-direction represents a direction in the Unicode bidirectional
algorithm.
Not every value in this enumeration makes sense for every usage of
enumeration PangoDirection defined in Gnome::Pango::T-direction; for example, the return value of [func $unichar_direction]
and [func $find_base_dir] cannot be PANGO_DIRECTION_WEAK_LTR or
PANGO_DIRECTION_WEAK_RTL, since every character is either neutral
or has a strong direction; on the other hand PANGO_DIRECTION_NEUTRAL
doesn't make sense to pass to [func $itemize_with_base_dir].
The PANGO_DIRECTION_TTB_LTR, PANGO_DIRECTION_TTB_RTL values come from
an earlier interpretation of this enumeration as the writing direction
of a block of text and are no longer used. See enumeration PangoGravity defined in Gnome::Pango::T-gravity for how
vertical text is handled in Pango.
If you are interested in text direction, you should really use fribidi
directly. enumeration PangoDirection defined in Gnome::Pango::T-direction is only retained because it is used in some
public apis.
