The 'GI.Pango.Objects.FontMap.FontMap' 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 'GI.Pango.Objects.FontMap.FontMap', the rendering-system
specific code should allocate a larger structure that contains a nested
'GI.Pango.Objects.FontMap.FontMap', fill in the \<structfield>klass\<\/structfield> member of the nested 'GI.Pango.Objects.FontMap.FontMap' with a
pointer to a appropriate 'GI.Pango.Structs.FontMapClass.FontMapClass', then call
@/pango_font_map_init()/@ on the structure.

The 'GI.Pango.Objects.FontMap.FontMap' structure contains one member which the implementation
fills in.

For instance, the GTK+ toolkit has, among others,

Returns the current serial number of /@fontmap@/.  The serial number is
initialized to an small number larger than zero when a new fontmap
is created and is increased whenever the fontmap is changed. It may
wrap, but will never have the value 0. Since it can wrap, never compare
it with \"less than\", always use \"not equals\".

The fontmap can only be changed using backend-specific API, like changing
fontmap resolution.

This can be used to automatically detect changes to a 'GI.Pango.Objects.FontMap.FontMap', like
in 'GI.Pango.Objects.Context.Context'.
