[vtkusers] vtkimagereslicemapper to get exact slice

[David Gobbi]

Hi Chasan,

Did you remove SetSlabThickness() from your code?
This  method causes adjacent slices to blend together,
even if the thickness is very small.  We use ROI images
with vtkImageResliceMapper all the time

There is no option to use bilinear interpolation instead of
trilinear.
