Title : [cairo] How can I enable synthetic bold in cairo?

Hello everyone,

I want to enable synthetic bold in cairo.
In _cairo_ft_scaled_glyph_init API, I can use FT_GlyphSlot_Embolden if scaled_font->ft_options.extra_flags has CAIRO_FT_OPTIONS_EMBOLDEN flag.
But this approach is only supported for cairo_ft_font_face_create_for_pattern.
Actually I use cairo_ft_font_face_create_for_ft_face API for creating font face.
So I suggest to add addtional parameter(cairo_ft_extra_flags_t) to cairo_ft_font_face_create_for_ft_face to enable synthetic bold.

* current code
cairo_font_face_t *
cairo_ft_font_face_create_for_ft_face (FT_Face         face,
           int             load_flags)
    //current code always set extra_flags as zero.
    ft_options.extra_flags = 0;

* My suggestion
cairo_font_face_t *
cairo_ft_font_face_create_for_ft_face (FT_Face         face,
           int             load_flags, cairo_ft_extra_flags_t extra_flags)
    ft_options.extra_flags = extra_flags;

Please give me some feedback.
Thank you in advance.
