Subject: (MFTInfo) [HAVE_XFT2]: New member fontname.
X-Git-Tag: withdl~221
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=4cf8f37a9e9485e4c44d4ba905ca6d33fed57260;p=m17n%2Fm17n-lib.git

(MFTInfo) [HAVE_XFT2]: New member fontname.
(all_fonts_scaned): New variable.
(set_font_info): FAMILY may be Mnil.
(add_font_info): Argument changed.
(xft_list): Call add_font_info in it.
(ft_list): Likewise.
(ft_select): Make it work in the case family is Mnil.
(ft_open) [HAVE_XFT2]: Setup ft_info->fontname.
(mfont__ft_fini): Set all_fonts_scaned to 0.
