Subject: [PATCH] Make GTK font chooser respect face-ignored-fonts
To: emacs-devel@gnu.org
* src/font.c (font_matches_ignored_fonts): New function, abstracts
out check for matching Vface_ignored_fonts.
(font_delete_unmatched): Use it.
* src/gtkutil.h: Add prototype for font_matches_ignored_fonts.
* src/gtkutil.c (xg_font_filter): New function, filters out fonts
from the GTK font chooser. Uses font_matches_ignored_fonts.
(xg_get_font): Set the GTK chooser font filter to xg_font_filter.
