Main Gtk struct. A cairo_font_face_t specifies all aspects of a font other than the size or font matrix (a font matrix is used to distort a font by sheering it or scaling it unequally in the two directions) . A font face can be set on a cairo_t by using cairo_set_font_face(); the size and font matrix are set with cairo_set_font_size() and cairo_set_font_matrix(). There are various types of font faces, depending on the font backend they use. The type of a font face can be queried using FontFace.getType. Memory management of cairo_font_face_t is done with FontFace.reference and FontFace.destroy. Since 1.0
