Owen Taylor a72aed4ea2 Implement a loader for named themed icon based on from gnome-desktop 
Wed Jul  2 18:00:56 2003  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkicontheme.[ch]: Implement a loader for
        named themed icon based on from gnome-desktop library
        by Alex Larsson.

        * gtk/gtkiconthemeparser.[ch]: .ini file parsing code
        from gnome-desktop.

        * gtk/gtkiconfactory.[ch]: Add
        gtk_icon_source_set/get_icon_name() to allow stock icons
        to be based off of named theme icons.

        * gtk/gtkiconfactory.c: Rework sources so that the source
        is *either* a pixbuf, or a filename, or an icon name,
        instead of the pixbuf/filename mix it was before. Put a
        workaround for get_pixbuf() so that it can return the
        filename pixbuf, e.g, for render_icon().

        * gtk/gtkiconfactory.c: Make the default setup use
        themed icons, and add builtin icons to the default
        icon theme for all the standard pixbufs, so we
        don't rely on actually having an icon theme on disk.

        * gtk/gtkrc.c: Add support for @"icon-name" to specify
        a themed icon for a stock icon source.

        * tests/Makefile.am test/testicontheme.c: Add a test
        program from gnome-desktop.

        * gdk/x11/gdkevents-x11.c gtk/gtksettings.c: Add
        Net/IconThemeName / gtk-icon-theme-name setting.

        * gtk/gtkiconfactory.c (ensure_cache_up_to_date): Actually
        update the icon cache serial so we don't continually

        * gtk/gtkwidget.c: Fix a couple of references in doc comments
        to ::direction_set that should have been to ::direction-changed
