Behdad Esfahbod 74b8297ee3 Bug 536185 – monitor font configuration 
2008-06-06  Behdad Esfahbod  <behdad@gnome.org>

        Bug 536185 – monitor font configuration

        * configure.in:
        * gdk/x11/gdksettings.c:
        * gtk/gtksettings.c (gtk_settings_class_init),
        (gtk_settings_notify), (settings_update_fontconfig):
        Monitor xsettings key Fontconfig/Timestamp and upon change,
        reread fontconfig configuration, clear Pango's caches, and
        redraw all widgets.
