[vtkusers] Error building VTK 64-bit

[Gib Bogle]

A couple more changes got the build further along, then it hit a compiler 
internal error in volumeRendering\vtkProjectedTetrahedraMapper.cxx.  Time to cut 
my losses here, I think.

The reason for wanting to build the 64-bit version is that I have to process 
some big 3D images, too big for a 32-bit program.  In fact the particular VTK 
filter I want use operates on 2D slices, so I do have the option of splitting 
the big 3D tiff into 2d tiffs, processing them, then recombining them.

There is another potential issue, though.  I want to use 
vtkImageIslandRemoval2D, but I see that the example on the VTK site apparently 
does not work: VTK/Examples/Broken/Cxx/Images/vtkImageIslandRemoval2D.  Has this 
been fixed?
