* e-shell-folder-title-bar.c: Remove some `#if 0'ed broken code. New members title_icon and title_button_icon in struct EShellFolderTitleBarPrivate. Remove member icon_widget. New static global variable empty_pixbuf. (init): Initialize these new members to NULL. Don't initialize icon_widget anymore since it's gone. (e_shell_folder_title_bar_construct): Create the title_button_icon and pack it into the title_button_hbox. Also, create the title_icon and pack that one as well. Retouched some of the hardcoded padding values. (size_allocate_icon): Rewritten to use the title_icon and return the allocated space like size_allocate_navigation_buttons. (e_shell_folder_title_bar_set_icon): Remove bogus const from the @icon arg. Ref the pixbuf, and update the two pixmap widgets from it. If @icon is NULL, use the empty_pixbuf. (impl_destroy): Renamed from destroy(). (realize): Removed. (unrealize): Removed. (impl_size_allocate): Renamed from size_allocate(). (class_init): Call it. (add_icon_widget): Removed. (new_empty_pixbuf): New. (new_empty_pixmap_widget): New. (size_allocate_navigation_buttons_and_title_icon): Renamed from size_allocate_navigation_buttons; set up the title_icon too. * e-shell-view.c (update_folder_title_bar): Unref the folder_icon after using it. * e-icon-factory.c (e_icon_factory_get_icon): Ref the returned pixbuf. svn path=/trunk/; revision=17419
