Summary:                    TransformDoubleVector of vtkTransform derivatives
does not work: rotates, but does not translate
Description: 
Constructed vtkLandmarkTransform does not correctly perform
TransformDoubleVector.

Values show that only rotation is being performed, but not translation.

---------------------------------------------------------------------- 
The behavior described in the report is not incorrect, that is exactly how
TransformDoubleVector is supposed to work: vectors are rotated but not
translated.

To achieve the desired result (rotation followed by translation), use the
TransformDoublePoint method.
