and non-vertical text correctly. This section describes the types used for setting
vertical text parameters.

+The way this is implemented is through the concept of *gravity*. Gravity tells glyphs which way is down, so the gravity of normal Latin text is south. A gravity value of east means that glyphs will be rotated ninety degrees
+counterclockwise. So, to render vertical text one needs
to set the gravity and rotate the layout using the matrix machinery already
in place. This has the huge advantage that most algorithms working on a
[class@Pango.Layout] do not need any change as the assumption that lines run
in the X direction and stack in the Y direction holds even for vertical text
layouts.

Applications should only need to set base gravity on [class@Pango.Context] in use,
and let Pango decide the gravity assigned to each run of text. This automatically
