set_gravity
Description:
Sets the gravity field of a font description.
The gravity field specifies how the glyphs should be rotated. If gravity
is pango_gravity_auto,
this actually unsets the gravity mask on the font description.
This function is seldom useful to the user. Gravity should normally be set on a `PangoContext`.
Parameters:
this |
a `PangoFontDescription` |
gravity |
the gravity for the font description. |
