[ROOT] Mean calculation in TH1

it looks like ROOT calculates fTsumwx (and hence Mean of a histogram) in 
TH1 incorrectly. 

But if you perform 
after the filling (or "zoom" by hands) it works correctly.

It looks likes in the first case it is not used the center of bin when  
fTsumwx is calculated.

Best regards,
