Sorry for my insistence but 'window-resize' has nothing to do with the
frame size.  My concerns are that we call 'window--size-to-pixel' when
we resize or split a window.  So if we want to special-code the split
window case and _not_ the 'window-resize' case, I have to either
special-code 'window--size-to-pixel' too or call some other function
instead.  Please have a short look at the involved functions and tell
me what you would do.
