[Insight-developers] Unlike in WarpImageFilter, WarpVectorImageFilter::SetDeformationField takes a non-const deformation field

[Bill Lorensen]

You could just add the const call and leave the old one. The Set ends
up calling ProcessObject::SetNthInput which does not take a const
input. This would be fully backward compatible.
