Hi, I think a bug was placed in vtk-9.2.2. In vtkResliceCursorRepresentation class at about line 309, line 310.  
in void vtkResliceCursorRepresentation::ResetCamera() function. It defined a vector of 3 dimensions like:

```auto
double worldFocalPoint[3];
 this->Renderer->GetWorldPoint(worldFocalPoint);

```

But when i debug in the GetWroldPoint function, it need a vector of 4 dimensions like i found in the vtkViewport class:

vtkSetVector4Macro(WorldPoint, double);  
vtkGetVectorMacro(WorldPoint, double, 4);

The bug was confirmed and fixed in the master branch 7 months ago (see [here](https://gitlab.kitware.com/vtk/vtk/-/commit/afb22c24be25262e8f6f298d35c4f7bd5cdaa787)). It should be available in the next release.

For further requests, please use a meaningful title. “Is it a bug?” is not acceptable.
