ThemedIcon.newWithDefaultFallbacks

Creates a new themed icon for iconname, and all the names that can be created by shortening iconname at '-' characters.

In the following example, icon1 and icon2 are equivalent:

const char *names[] = {
  "gnome-dev-cdrom-audio",
  "gnome-dev-cdrom",
  "gnome-dev",
  "gnome"
};

icon1 = g_themed_icon_new_from_names (names, 4);
icon2 = g_themed_icon_new_with_default_fallbacks ("gnome-dev-cdrom-audio");
