### visibility_in, visibility_out

visibility_out controls whether the layer, when current, attempts to see the other layers: all - try to see the other layers; partial - try to see the other layers in a blurred way, to distinguish them from the current layer; none - ignore the other layers.

visibility_in controls whether the layer autorizes other layers, when current, to look inside: all - the layer can be seen; partial: the layer can be seen in a blurred way, to distinguish it from the current layer; none - the layer cannot be seen from the outside.

visibility_in (a privacy condition) has always priority over visibility_out (a curiosity condition). By default layers are completely transparent, to the inside and to the outside.

    Example: <layer ... visibility_in="all" visibility_out="all"/> (default)
    (defined in GAMGI_MESA_TRANSPARENT)
    Allowed values: all, partial, none (optional)
