/**
* PangoFontMap:
*
* 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.
*
* The #PangoFontMap structure contains one member which the implementation
* fills in.
