## Detailed Description

Gdk::CairoFontMapImpl is a Pango::FontMap that implements the Pango::CairoFontMap interface.

The PangoCairoFontMap interface can be implemented by C classes that derive from PangoFontMap. No public Pango class implements PangoCairoFontMap. Some Pango functions, such as pango_cairo_font_map_get_default(), return an object of a class which is derived from PangoFontMap and implements PangoCairoFontMap. Since that C class is not public, it's not wrapped in a C++ class. A C object of such a class can be wrapped in a Pango::CairoFontMapImpl object. Pango::CairoFontMapImpl does not directly correspond to any Pango class.

This class is intended only for wrapping C objects returned from Pango functions.
