 * @class   vtkResliceCursorPicker
 * @brief   ray-cast cell picker for the reslice cursor
 *
 * This class is is used by the vtkResliceCursorWidget to pick reslice axes
 * drawn by a vtkResliceCursorActor. The class returns the axes picked if
 * any, whether one has picked the center. It takes as input an instance
 * of vtkResliceCursorPolyDataAlgorithm. This is all done internally by
 * vtkResliceCursorWidget and as such users are not expected to use this
 * class directly, unless they are overriding the behaviour of
 * vtkResliceCursorWidget.
