// .NAME vtkCheckerboardRepresentation - represent the vtkCheckerboardWidget
// .SECTION Description
// The vtkCheckerboardRepresentation is used to implement the representation of
// the vtkCheckerboardWidget. The user can adjust the number of divisions in
// each of the i-j directions in a 2D image. A frame appears around the
// vtkImageActor with sliders along each side of the frame. The user can
// interactively adjust the sliders to the desired number of checkerboard
// subdivisions. The representation uses four instances of
// vtkSliderRepresentation3D to implement itself.
