BackTransform for a mitk::Vector is not affected by the world coordinate voxel center shift.
Still, it uses the ITK method Transform->GetInverseMatrix(), which has shown to be unstable on matrix inversion for 3D matrices.
It should be replaced as shown in T1995. (By Transform->GetInverse->GetMatrix) which seems to be stable.
Daniel M., again, please comment on this.

FIX (#2884): Use stable matrix inversion; relocated multiplication to separate function.
Fixed by using ->GetInverse.
Relocated Multiplication with inverse matrix to seperate method
MultiplyWithWorldToIndex.
