// of other state variables to determine what is going on with
// the currently displayed menus.
// So the main loop (handlemenu()) puts all the state in a structure
// and puts a pointer to it in a static location, so the handle()
// on menus can refer to it and alter it.  The handle() method
// changes variables in this state to indicate what item is
// picked, but does not actually alter the display, instead the
// main loop does that.  This is because the X mapping and unmapping
// of windows is slow, and we don't want to fall behind the events.
