Take a look at vtkCoordinate. It has all the methods you need to
convert a vector from one coordinate system to another. See
(./Rendering/Testing/Cxx/otherCoordinate.cxx) as an example. You
should be able to convert the world coords to NormalizedViewport
coords and then pass them along to the BorderWidget. Isn't that so ?
