[vtkusers] VTK Model and ITKImageBase itkImage_UC3

[David Gobbi]

Hi Sam,

The vtkPolyDataToImageStencil just creates the stencil. After that, you need
to use one of the image filters to apply the stencil to the image.

polydata -> vtkPolydataToImageStencil -> stencil

image (first input) and stencil (2nd input) -> vtkImageAccumulate -> image
histogram/statistics

The first filter just produces the stencil, but then the stencil is used as
the 2nd input (via SetStencil) for image filters like vtkImageStencil,
vtkImageBlend, vtkImageAccumulate, etc.

The test file VTK/Hybrid/Testing/Tcl/TestImageStencilWithPolydata.tcl is an
example of how to use it.
