    css: buttons can be active without be hovered
    
    For instance, GtkToggleButton implementations which are not radio/check
    buttons; those were themed as normal buttons, which makes them not
    recognizable as active.
    The gradient for this is stolen from a previous version of this same CSS
    file.
