// .NAME vtkResliceCursorPicker - ray-cast cell picker for the reslice cursor
// .SECTION Description
// 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.
