bug in vtkImageCheckerboard with 2D data if number of dimensions in Z is > 1

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Two 2D datasets as input to the vtkImageCheckerboard, default
SetNumberOfDivisions == 2,2,2

What is the expected output? What do you see instead?
I expect a checkerboard, instead I get a floating point exception and
DeVIDE is terminated.

vtkImageCheckerboard is doing something stupid: If I set numberofdivisions
to 2,2,1 in this case, all is fine.  Doh.
