[vtkusers] Splitting vtkImageData in vtkImageData (for each stack image)

Hi,

vtkImageReslice and vtkImageAppend are what you want to use:
- vtkImageReslice will allow you to get a specific image slice as
vtkImageData. Just do what you want with (transformation) and memorize it
- vtkImageAppend will be able to 'glue' each memorized transformed image.

HTH,
Jérôme
