- /**
- * PangoGravity:
- * @PANGO_GRAVITY_SOUTH: Glyphs stand upright (default)
- * @PANGO_GRAVITY_EAST: Glyphs are rotated 90 degrees clockwise
- * @PANGO_GRAVITY_NORTH: Glyphs are upside-down
- * @PANGO_GRAVITY_WEST: Glyphs are rotated 90 degrees counter-clockwise
- * @PANGO_GRAVITY_AUTO: Gravity is resolved from the context matrix
- *
- * The #PangoGravity type represents the orientation of glyphs in a segment
- * of text. This is useful when rendering vertical text layouts. In
- * those situations, the layout is rotated using a non-identity PangoMatrix,
- * and then glyph orientation is controlled using #PangoGravity.
- * Not every value in this enumeration makes sense for every usage of
- * #PangoGravity; for example, %PANGO_GRAVITY_AUTO only can be passed to
- * pango_context_set_base_gravity() and can only be returned by
- * pango_context_get_base_gravity().
- *
- * See also: #PangoGravityHint

- * @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.
