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_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
