Hi Martin,
Why did you mark all these NEWS entries with ---?
It is not obvious to me that no doc changes are needed.
Eg on a specific level, funtions like window-total-size are documented
in the manual, and take different arguments now.
And on a general level, why should the manuals make no mention
whatsoever of "dividers", pixelwise resizing, etc?
