[gtk+/wip/unfocused-fixes: 7/13] calendar: Use the widget state flags as a base for drawing arrows

    calendar: Use the widget state flags as a base for drawing arrows
    
    This allows drawing calendar arrows in all possible states the main widget may
    be in.
    
    The arrow_state array is converted into a bit field since it only really needs
    to store boolean information about prelight for each arrow.
