I agree absolutely.  Emacs should not touch window size when it
shows/hides its widgets.

I have this in my `~/.Xdefaults':

Emacs.menuBar:		off
Emacs.toolBar:		0
Emacs.geometry:		139x54+0+0

because I don't need the menu and the toolbar, but if I hide them
from `~/.emacs', then Emacs'es window size changes and that is very
annoying.  And, btw, I'm not satisfied with the above solution
because it is extremely non-obvious, was very difficult to find and
there is high chance that I forget to preserve `~/.Xdefaults'
contents when upgrading my system next time.
