I'll add a 'resize-pixelwise' frame parameter soon.  Then 'clone-frame'
would simply have to inspect the parameter of the frame to clone and we
are done.

Other packages might have to adapt too since with the new parameter a
user could never have set 'frame-resize-pixelwise' and still have frames
that resize pixelwise.
