/* Gtk module justification:
 *
 * The sole purpose of this module currently is to add a 'Favorites'
 * shortcut to GtkFileChooser dialogs.
 *
 * In gtk_module_init, the 'favorites' uri scheme is added to the default
 * vfs. Ordinarily, non-file:// schemes aren't supported in these dialogs
 * unless their 'local-only' property is set to FALSE. Since favorites
 * are shortcuts to locally-available files, we lie to the chooser setup
 * by returning "/" instead of NULL when g_file_get_path ("favorites:///")
 * is called.
