[Paraview] Large TIFF file import in paraview fails

[Mike Jackson]

Trying to allocate that many elements at 8 bytes each takes  
1,474,563,760 bytes or 1.4 GB. If ParaView was compiled for 32 bit  
then you may have reached its limit. I know on my own OS X machine  
with when ParaView gets much above 1GB of used RAM I should start  
praying..

I don't pretend to know anything about memory management under any of  
the Operating Systems. In my naive world, even in 32 bit mode there  
should be at minimum about 2GB of Memory available, or 4GB if the  
memory pointer that is used is and unsigned 32 bit integer. That is  
in my own little world where I understand things. In the real world  
it doesn't work that way. Maybe someone can explain it to us.

Cheers
