The PangoFontMap represents the set of fonts available for a particular rendering system. This is a virtual object with implementations being specific to particular rendering systems. To create an implementation of a PangoFontMap, the rendering-system specific code should allocate a larger structure that contains a nested PangoFontMap, fill in the <structfield>klass</structfield> member of the nested PangoFontMap with a pointer to a appropriate PangoFontMapClass, then call pango_font_map_init() on the structure.
Undocumented in source.
