(Basic Window): When using a window system, the value of point in a

non-selected window is indicated by a hollow box.
(Split Window): Side by side windows are separated by a scrollbar,
if scrollbars are used.
C-Mouse-2 on scrollbar now also works for toolkit scrollbars.
(Change Window): Correct Mouse-2 vs Mouse-3 mess-up.
(Window Convenience): Update bindings for `winner-undo' and `winner-redo'.
