The vtkTransformFilter is supposed to do those things, it works on all
vtkPointSet derived data object, which includes all the ones you
mentioned.  A generic vtkTransformDataSetFilter isn't possible because
for some data sets (i.e. vtkImageData) the points in the data are
implicit and must stay aligned with the x, y, and z axes.
