    cairo_matrix_set_identity(scale);

    cairo_font_t *font;

    ASSERT((font =
            cairo_ft_font_create_for_ft_face(face, FT_LOAD_DEFAULT,
                                             scale)) != NULL);
    cairo_matrix_destroy(scale);

You have to use the real scale here.

    cairo_set_font(cr, font);

[...]

        cairo_scale_font(cr, fontSize);

scale_font refers only to the font selected by cairo_select_font(),
calling it after set_font() will clear the previously set font.

It could be argued that cairo_ft_font_create_for_ft_font() isn't a
terribly useful in the present form - see

 http://lists.freedesktop.org/archives/cairo/2005-January/002805.html

for some comments on the subject. Not having a use for the function
myself I'm not sure I have a very good idea of what is needed in this
area.
