Luis, Karthik,

I have just fixed a small bug in HistogramToImageFilter, but while doing that, I noticed that the origin and spacing provided by the user are always overiden by the filter:

http://www.itk.org/cgi-bin/cvsweb.cgi/Code/Numerics/Statistics/itkHistogramToImageFilter.txx?root=Insight&r1=1.3&r2=1.4

2 choices:
(a) remove the SetOrigin() and SetSpacing() methods, because they are useless
(b) use the values provided by the user instead of computing new ones

I think that (b) is the best option, but as I don't understand why those values are modified in GenerateData(), I'm not completly sure :-)

Gaetan
