`mitk::SliceNavigationController::Frontal` should be replaced with `Coronal`. In combination with the parent task the question is, if we remove `mitk::SliceNavigationController::ViewDirection` completely.
`mitk::PlaneGeometry::Frontal` should be replaced with `Coronal`. In combination with the parent task the question is, if we remove `mitk::PlaneGeometry::PlaneOrientation` completely.
`Transversal` is occasionally used as a string or inside comments.
