(cursor_type_changed): New variable.

(redisplay_internal): Redisplay all windows if cursor_type_changed.
Clear it when clearing windows_or_buffers_changed.
(try_cursor_movement, redisplay_window, try_window_id)
(try_window_reusing_current_matrix): Test cursor_type_changed
along with windows_or_buffers_changed.

(clear_garbaged_frames): Don't set windows_or_buffers_changed
if no frames needed redrawing.
