    PanelImage: allow scaling the image down (below allocation)
    
    Some containers (GtkBox(?)) refuse to allocate their child items below
    minimum requested size, even if that results in violating their own
    allocation.
    
    Reducing the minimum size allows these containers to iteratively
    reduce the size of the embedded PanelImage.
    
    When priv->size > 0 minimum size must be equal to the natural size.
    Otherwise icons displayed in menus will be too small (menus use
    a minimum size).
