[vtkusers] Problems with ComputeOBB - wrong OBB computed

Yes, it would be nice to have it in vtkMath.

Variance calculation can easily be integrated in this calculation.

static int vtkMath::GetMean(vtkDataArray *array, int dim, double* mean,
double* variance) 

So variance can additionally calculated if variance!=0.

I will have a look on Gerrit tomorrow .
