[vtkusers] How to use vtkImageReslice to get oblique slice with arbitrarily position and direction

[Alessandro Volz]

When that happened to me, I fixed it with reslice->SetOutputOrigin(0, 0, 0). Without that, VTK somehow cropped the output.

If you've already set the output origin to 0,0,0, then you have to compute a better origin to pass in the ResliceAxes. In my code, to determine the origin I apply my outputSliceToInputVoxelTransform to a 0,0,0 vector, and it just works.
