[vtk-developers] Adding vtkAbstractTransform::Shear() method

[Will Schroeder]

David-

I am working on a VTK widget:: vtkAffineWidget and its representation 
vtkAffineRepresentation2D. I would like to support shears which as you 
know are affine transformations. To do this I've thought about adding a 
vtkAbstractTransform::Shear() method to do the actual fiddling with the 
transformation matrix, patterning it after the basic linear 
transformations Translate, Scale and Rotate (i.e., using the internal 
vtkTransformConcatenation). Are you okay with this? Other suggestions?
