bug#29050: 26.0; Change in when `window-configuration-change-hook' is run

[martin rudalics]

>> 'window-configuration-change-hook' is a quite expensive hook which is
>> run for way too many functions in the windows area.  It's expensive
>> because it's run for every single invocation of these functions and
>> often even if nothing had changed at all.  I plan to run it exclusively
>> for the following cases - window deletion and creation and displaying a

>> resizing is covered by ‘window-size-change-functions’ which is now run
>> (almost) only when the size of a window really changed.

> OK.

Closing this bug then.

Thanks, martin
