Subject: (find_ccl_program_func): New variable.
X-Git-Tag: emacs-20.3~1522
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=727fb7903df0bfca302ac64abf7a7d714c515cab;p=emacs.git

(find_ccl_program_func): New variable.
(fs_load_font): Call a function pointed by find_ccl_program_func
instead of finding CCL program to encode a character by itself.
(Fquery_fontset): New optional 2nd arg REGEXPP.  Callers changed.
