[vtkusers] vtkVolumeRayCast* gone in VTK 8.1.0

[Sankhesh Jhaveri]

Hi Alessandro,

Those classes had been deprecated since VTK 7.0. They were removed in
version 8.1.0

The modern approach to volume rendering in VTK is using the
vtkGPUVolumeRayCastMapper
<https://www.vtk.org/doc/nightly/html/classvtkGPUVolumeRayCastMapper.html>.
There are some examples
<https://lorensen.github.io/VTKExamples/site/Cxx/VolumeRendering/SimpleRayCast/>
as well as tests
<https://www.vtk.org/doc/nightly/html/c2_vtk_t_7.html#c2_vtk_t_vtkGPUVolumeRayCastMapper>
that show how to set it up.

Hope this helps.

Best,
Sankhesh
