There is an "opaque" hint in the capabilities document that suggests
that the layer should be a base layer. Other than that the layers are
just drawn in the order the client requests them and there is no
implied ordering from the capabilities file. For example GeoServer
returns the layers in alphabetical order by namespace then layer name.
