The problem is the named view includes the solid rendering submodel of volume, but that submodel is not saved in the session since it is recreated by the volume model. Have to think about how to handle this.

[Tom Goddard]

Fixed.

Made image rendering submodel restore itself in sessions so that named views and other tools can save references to this model.
