 * 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().

 * @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.
