[vtkusers] Tiling a window with images

[David Gobbi]

Hi Erik,

It is probably much easier to do this with a vtkImageWindow than
with a vtkRenderWindow and a whole bunch of texture-mapped planes.   
Take a look at one of the examples that draws multiple images in
the same window, e.g. contrib/examplesTcl/InterpolationModes.tcl
or imaging/examplesTcl/TestViewports.tcl

The best way to do this is probably to use one vtkImageReslice
(use it to shrink the whole volume along the X and Y axes while 
leaving the Z-axis as-is), and a whole bunch of vtkImageMappers
(each set to a different ZSlice) and vtkImagers all within the
same vtkImageWindow.
