the osgGA::AnimationPathManipulator to handle it. Added a new Drawable::ConstAttributeFunctor and make the accept(PrimitiveFunctor) be a const method so can disallows modification. Added Drawable::supports(...) methods for each of the AttributeFunctor, ConstAttributeFunctor and PrimitiveFunctor so that programs can querry whether it is possible to use functors with that object type.
