Remove no longer needed apply(Geode&) in SetFilterSettingsVisitor and NodeToShapeVisitor

In OSG 3.4 (which is now a requirement), Drawables are normal Nodes attached in the scene graph. Geode is still provided for backwards compatibility, but does not need to be specially handled here because it now functions just like a normal Group node.
