David G, if we don't hear any screaming would you volunteer to verify my commit of moving vtkLandmarkTransform to Common (to github) before we push to VTK master?</div><div><a href="http://github.com/daviddoria/daviddoria-vtk/commit/e97738896ed41aa007424f9fefb5a5d2a9a0aa78" target="_blank"></a><br clear="all">
