When the DICOM patient coordinate system is used as the VTK world
coordinate system, the assumption is that everything (images AND
polydata) would have a either already be in the patient coordinate
system, or if not, you would to have a 4x4 transform to set as the
actor's UserMatrix (or UserTransform).  I.e. a transform to bring the
data from its original coordinate system into the patient coordinate
system.
