Summary	0004507: vtkActor::GetBounds returns unitialized bounds when no mapper is connected
Description	The code for vtkActor::GetBounds blindly returns the actor's Bounds as the bounds, and doesn't check to see if it is initialized or not. There is a check in the mapper code to see if the mapper's bounds are initialized. if not, then it returns a null pointer to bounds. I believe that a null bounds should be returned if there is no mapper, and the actor's bounds are unitialized. This has consequences for vtkAssembly::GetBounds because the assembly does not check for null pointer return on the child GetBounds calls. Thus, if you include an actor in an assembly that does not have a mapper, then the values -1, and 1 will be included in the collective bounds calculation for the assembly, thus returning incorrect bounds.
