* @class vtkImageCheckerboard
* @brief show two images at once using a checkboard pattern
*
* 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.
