 Window change functions are called at the end of redisplay for each
 frame as follows: First, any buffer-local window buffer change
-function, window size change function and selected window change
-functions are called in this order.  Next, the default values for
-these functions are called in the same order.  Then any buffer-local
-window configuration change functions are called followed by functions

    Window change functions are run for a specific frame only if a
 corresponding change was registered for that frame earlier.  Such
