X11 highlight yn prompting

For the 'slow' config (prompting for single-char input done on a
fixed line at the top of the map rather than via a popup window),
invert the background and foreground when creating it so that it
looks like part of the map, then invert again when a prompt is
active in order to highlight that prompt.
