[vtkusers] vtkImageReslice --> vtkTexture

[David Thompson]

Hi,
  I'd like to use the results of a vtkImageReslice as a texture to be mapped 
onto a vtkActor (via vtkPlaneSource). Right now it's working well, except that 
the texture is projected onto the plane in colour, and I'd like the original 
grayscale of the reslice. Can I solve my problem with a lookup table? I can't 
seem to get the right values if that is the case. Any suggestions would be 
appreciated. Thanks,

David Thompson
