    GtkPopover: Use display-hint for menus
    
    When an 'iconic' display-hint is specified on a section,
    render the actions as a row of iconic model buttons, instead
    of like menu items. We're using the verb-icon attribute
    here, to keep noun and verb icons cleanly separated.
    
    This works with regular actions, as well as with toggle and
    radio actions.
