[cairo] Re: FcPattern vs. font options

[sunmoon1997]

hi,
   I attached two updated testcases and the patch(removed all unralated
stuff and fixed a stupid bug).
   cairo-1.0.x fails testcase cairo-text-antialias-font-options and
passes cairo-text-antialias-fcpattern. cairo-1.1.x(without my patch)
get opposite results. cairo-1.1.x(with my patch) passes both of them.
