// .NAME vtkImageCheckerboard - show two images at once using a checkboard pattern
// .SECTION Description
// vtkImageCheckerboard displays two images as one using a checkerboard
// pattern. This filter can be used to compare two images. The
// checkerboard pattern is controlled by the NumberOfDivisions
// ivar. This controls the number of checkerboard divisions in the whole
// extent of the image.
