[vtkusers] Compile Bug in VTK 5.6

[David Gobbi]

Do you mean VTK git master?  There's a difference between VTK 5.6 and
the latest VTK from git.

I think that vtkTIFFReader.cxx has some old templated functions inside
of it that aren't used anymore.  The right way to patch the file would
be to simply remove those functions (ReadTiledImage and
ReadScanlineImage) completely.
