    A FeatureRef is the minimum information a renderer needs to
    identify which feature in the layer it is being asked to paint:
    the owning layer's id and the feature's index within that layer.
    An optional category hint disambiguates layers that hold multiple
    element kinds (e.g. SWMMModelLayer's nodes vs. links).

    Renderers should treat FeatureRef as opaque — the actual attribute
    data is supplied via the parallel QVariantMap argument so the
    renderer doesn't have to know about the layer's storage layout.
