Summary:                    Silence alignment change cast in vtkImageReader.cxx
Description: 
Run into this with our 'paranoid' build flags and CLang.  Git version 
86d156256c76a98

CLang complains about line 324 in vtkImageReader.cxx

Not a real problem because the templating should mean that casting to a wider
type is actually a good cast. The patch below makes the warning go away, though
there might be a more elegant solution:

diff --git a/IO/Image/vtkImageReader.cxx b/IO/Image/vtkImageReader.cxx
index 1125fee..eaccc09 100644

       for (idx0 = dataExtent[0]; idx0 <= dataExtent[1]; ++idx0)
