[vtkusers] Bug in vtkTIFFReader reading multi-paged tiff file

[David Gobbi]

Hi Maarten,

Which version of VTK are you using?  I believe that this bug has been
fixed in the master branch by a commits in the following topic merge:
http://vtk.org/gitweb?p=VTK.git;a=commitdiff;h=7e3d5270

It was not fixed in time for VTK 5.10, however.

  David
