/**
 * @class   vtkResliceImageViewer
 * @brief   Display an image along with a reslice cursor
 *
 * This class is similar to vtkImageViewer2. It displays the image along with
 * a two cross hairs for reslicing. The cross hairs may be interactively
 * manipulated and are typically used to reslice two other views of
 * vtkResliceImageViewer. See QtVTKRenderWindows for an example. The reslice
 * cursor is used to perform thin or thick MPR through data. The class can
 * also default to the behaviour of vtkImageViewer2 if the Reslice mode is
 * set to RESLICE_AXIS_ALIGNED.
