Change machinery for following font rendering xsettings to set cairo font
2005-07-19 Owen Taylor <otaylor@redhat.com>
* gtk/gtksettings.c gtk/gtkwidget.c: Change machinery for
following font rendering xsettings to set cairo font
options on PangoContext
* gdk/x11/gdkxftdefaults.c gdk/x11/gdkevents-x11.c gdkscreen-x11.h
gdkprivate-x11.h: Get default values for rendering options
(such as antialiasing, dpi) from the Xft resources for the
display, borrowing a bit of code from Xft.
* gtk/gtksettings.c (gtk_settings_class_init): Fix docs for
values of gtk-xft-hintstyle.
