IMO the widget.c code is inherently absurd.  EmacsFrameResize processes
a resize request by calculating a text size from ew->core.height.  Then
it sets

  FRAME_PIXEL_HEIGHT (f) = ew->core.height + x->menubar_height;

and update_from_various_frame_slots inversely processes

  ew->core.height = FRAME_PIXEL_HEIGHT (f) - x->menubar_height;

where update_from_various_frame_slots is called only by
EmacsFrameInitialize.  Does anyone understand what this is good for?
