Hi David,

Many thanks for improving vtkPolyDataToImageStencil. I tested the git branch on 
141229 in conjunction with my Voxelizer plug-in for Blender 
(http://www.midasjournal.org/browse/publication/882) and I still get some 
artifacts in the result (see first two slices of attached MHA) with e.g. an 
icosahedron (scale set to 100) as found in the attachment. Is that related to 
the bugs of vtkPolyDataToImageStencil?

Kind regards,
