MemoryMappedFile's constructor tries to map memory to a file. If this succeeds, valid() will return true and all fields are usable; otherwise, valid()

* On the GPU, it is necessary that the RayVolumeState is initialized manually as opposed to in a default constructor for example. * That's because t
