During the VTK-m 1.8 and 1.9 development, the filter infrastructure was overhauled. Part of this created a completely new set of base classes. To avoid confusion with the original filter base classes and ease transition, the new filter base classes were named `NewFilter*`. Eventually after all filters were transitioned, the old filter base classes were deprecated. With the release of VTK-m 2.0, the old filter base classes are removed. The "new" filter base classes are no longer new. Thus, they have been renamed simply `Filter` (and `FilterField`).
