The pango:gravity enumeration 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 pango:matrix instance, and then glyph orientation is controlled using a pango:gravity value. Not every value in this enumeration makes sense for every usage. For example, the :auto value only can be passed to and returned by the pango:context-base-gravity function.
