I can't understand.  Emacs uses ncurses, and ncurses uses a single type
for both root window (the ncurses window covering the whole terminal; I
can't remember the name ncurses uses for this) and other windows.  Does
Emacs assume while render a frame that its drawing on the root window or
is it impossible to tell ncurses precisely which window to draw above?
