[vtkusers] Use vtkImageSlice GPU.

Use vtkImageSlice with vtkImageResliceMapper-> SetSlabThickness (images of
the maximum file MHD), is around + - 100 images added.

use to have this vision:
the problem is that when utilizdo any camera movement
(vtkInteractorStyleTrackballCamera) for this object, it is processed on the
CPU rather than the GPU.

I saw an old post that the interpolator Imageslice does not work with the
GPU, but that in 2011 an old version of VTK.

nowadays it is already possible to pass this processing to the GPU?
Has some way to ease the locking of this object when it is rendered?

I am using a computer with the following settings:
video card nvidia 730
intel i7 (3770) 3rd generation
Memory 16gb

and still move this object becomes unfeasible with active SetSlabThickness
for me.
