[vtk-developers] Wiki example strangeness

[Andrew Maclean]

The first image is generated on a windows machine and the second is done on
a Linux machine. The same random seed is used but the random number
generator is different for windows & Linux hence the different shaped
hills. Both images should be 800 x800.
