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().
