[vtkusers] vtkImageStencilData to vtkImageData

[David Gobbi]

Hi Luis,

Two steps are required.  First vtkPolyDataToImageStencil, and then
vtkImageStencil to apply the stencil to an image.  See the following
example:

Hybrid/Testing/Tcl/TestImageStencilWithPolydata.tcl

If you just want to create a binary image, then you will have to
replace the "reader" in the example with something that will
create a blank image.
