BUG: Fixed vtkImageReslice HitInputExtent update
If this->ResliceTransform was not a vtkHomogeneousTransform then the whole input extent was updated and then the method immediately returned. However, the this->HitInputExtent flag was not updated. If the this->HitInputExtent had been 0 before then the output of the filter remained always 0 and the output of the filter was always empty.
