Then I don't see any motivation to move the platform dependent parts to
change_frame_size.  It would only make the code uglier than it already
is.

As a matter of fact, I only pretended to doubt.  Anyway, the entire
window resizing code now works pixelwise so on TTY frames nothing will
change.

Which makes me wonder why calc_absolute_offset looks like it does.
