* @PANGO2_DIRECTION_WEAK_RTL: A weak right-to-left direction
* @PANGO2_DIRECTION_NEUTRAL: No direction specified
*
* `Pango2Direction` represents a direction in the Unicode bidirectional
* algorithm.
*
* Not every value in this enumeration makes sense for every usage of
* `Pango2Direction`; for example, the direction of characters cannot be
* `PANGO2_DIRECTION_WEAK_LTR` or `PANGO2_DIRECTION_WEAK_RTL`, since every
* character is either neutral or has a strong direction; on the other hand
* `PANGO2_DIRECTION_NEUTRAL` doesn't make sense to pass to [func@itemize].
*
* See `Pango2Gravity` for how vertical text is handled in Pango2.
*
* If you are interested in text direction, you should really use
* [fribidi](http://fribidi.org/) directly. `Pango2Direction` is only
* retained because it is used in some public apis.
