    app, libgimp: disable transition for all GtkPopover code we have.
    
    This popping-up|down transition code is so utterly broken that it's
    unusable. Anyone working with fast pace will encounter broken behavior
    where the popup will not appear unless you click a second time, or not
    disappearing immediately, displayed like a ghost of itself (feels like
    a widget exposition bug even). So let's just disable it everywhere.
    
    So I don't care it's marked as deprecated already, this widget is not
    usable without disabling this transitional logics.
    
    I'm not using gtk_popover_set_transitions_enabled() because it will
    produce build warnings unlike setting the property directly.
