[vtkusers] Writing TIFF images

[Dr. Carsten Bellon]

I found the problem, I think. In vtkTIFFWriter.cxx of VTK 5.0.1:
TIFFTAG_PHOTOMETRIC is set as subject to the data scalar type. Why?

My Fix
from:
  uint16 photometric = (stype == VTK_FLOAT ? PHOTOMETRIC_MINISBLACK : 
PHOTOMETRIC_RGB);
to:
  uint16 photometric = (scomponents == 1 ? PHOTOMETRIC_MINISBLACK : 
PHOTOMETRIC_RGB);
