(cairo_font_options_set_lcd_filter) because "they are too specific to

Well, maybe that is true.  But now how can I use the real Freetype default
filter (FIR5) in the newest cairo without pathcing it?  I think maybe manually
set a FcPattern is OK but I really do not want to learn/invoke/rely Fontconfig
just for setting a filter that should be default.
