I think so. I think that should be our goal anyway.

That depends on what you mean by 'this'. If you mean 'Emacs always
works in pixels regardless of scaling', then 'Coordinates and Windows'
in windows.texi would be a good place. I'm just not sure we can
guarantee that yet (I know that e.g. frameset-restore misbehaves in
the presence of scaling, and I haven't tracked down why yet)
