Attach PANELs to all of our WINDOWs We replace wnoutrefresh with update_panels (except in set cursor; there we have to guarantee that the window is empty.). The viewwin does not get a PANEL because it's weird and currently leeches onto someone else's WINDOW. Resizing is also rather fiddly because panel wants to know about window resizes. Not completely sure I got it right yet. The only library I know of that does something like with with ncurses (libgnt) and they endwin/refresh to resize the screen.
