    treeview: default to width_changed = TRUE
    
    Checking the given GtkAllocation against the current allocation insize
    ::size-allocate doesn't really work anymore. They are only different if
    the content allocation (the one passed) and the widget allocation (the
    current one) are different, so e.g. when the widget has padding >0
    applied.
