Fontconfig options for freetype sub-pixel filter configuration
David Turner has modified FreeType to be able to render sub-pixel decimated
glyphs using different methods of filtering. Fontconfig needs new
configurables to support selecting these new filtering options. A patch
follows that would correspond to one available for Cairo in bug 10301.
