Comment 123 for bug 145604

I am trying to enable subpixel rendering on poppler and I found my rendering result is suboptimal. After gdbing into cairo, I am surprise that cairo is still using the legacy filter as the "default". To the the situation even worse, cairo removed the interfaces to set the lcdfiler (cairo_font_options_set_lcd_filter) because "they are too specific to FreeType".

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.
