--- Comment #23 from Peng Wu pwu@redhat.com --- As Akira Tagoh said, there are two issues in the code, so I just updated my patch.

1. The usage of FcFontMatch may be not correct, as it doesn't compare the FC_INDEX when matching. In the patch, I switch to use FcFontSort, the FcFontSort code will match FC_FILE; and after the FcFontSort function return, we compare the FC_INDEX to get the correct font face.

2. Switch to use the embolden value from the fontconfig, instead of computing it in the freetype code in Linux. The freetype code will override the embolden value from fontconfig, so the patch also disables the freetype code to compute the embolden value in Qt.
