Detailed Description

allows operations on any transforms

vtkGeneralTransform is like vtkTransform and vtkPerspectiveTransform, but it will work with any vtkAbstractTransform as input. It is not as efficient as the other two, however, because arbitrary transformations cannot be concatenated by matrix multiplication. Transform concatenation is simulated by passing each input point through each transform in turn.
