[vtkusers] VTKPolyData to 3D image

[David Welch]

Hi Lars,
I can confirm that there is an offset to the images.  The origin is computed
as the lower(?) bounds for x,y, and z.  I believe that these should be the
average of the upper and lower bounds so as to obtain the center.
Unfortunately, when I try to implement that in the code,
PolyDataToImageStencil seg faults on it's update.  Any idea why that would
be?

I'd also suggest adding additional space around the image so that the
surface voxelization doesn't butt up against the image edges
