Subject: (free_frame): Don't free frame->font.
X-Git-Tag: REL-1-3-0~295
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=68568403ee1d614815a23a722d520812b6f98bfd;p=m17n%2Fm17n-lib.git

(free_frame): Don't free frame->font.
(null_device_fini): Fix code for freeing
null_device.realized_font_list.
(m17n_fini_win): Free interface.
