[vtkusers] imageSliceMapper->GetSliceNumber() problem

[David Gobbi]

Hi Concetta,

The superclass of vtkImageResliceMapper is vtkImageMapper3D, the
SliceMapper has a GetSliceNumber method but the ResliceMapper does
not.

The only way to get the slice from ResliceMapper is with the
GetSlicePlane() method.  This returns a vtkPlane object that describes
the slice plane.  If you need a slice number, then you will have to
compute it from the position of the SlicePlane.

It makes no difference if you are using VTK 5.10 or VTK 6.0, the
vtkImageResliceMapper class is identical in both.
