[vtkusers] Problem using vtkAppendPolyData with vtkPolyDataToImageStencil

[David Netherway]

I made minor modifications to TestImageStencilWithPolyData.tcl to use an
appended polydata of two spheres. The blanked out region in the image did
not match the expected union of the two spheres. See attached code. Is
vtkPolyDataToImageStencil supposed to work with appended data or should one
have a pipeline processing each polydata at a time?

I am using the CVS vtk4 download of 2 hous ago.

Thanks, David
