[vtkusers] Porting Osirix to Linux / Windows

[Mike Jackson]

vImage is accelerated for the AltiVec engine where as my guess is  
that VTK is _not_ (I have not even looked that deep, but I would  
guess AltiVec optimizations are not even on the radar of VTK). So  
there  is most likely a large speed difference between vImage and the  
vtk Image processing routines.

Just my 2 cents.
