Summary	0006909: vtkPointHandleRepresentation2D SetDisplayPosition() bug
Description	I've recently struggled with using vtkPointHandleRepresentation2D as the handle representation when using vtkSeedWidget along with a vtkImageActorPointPlacer. The problem has been that any seeds placed stay in the same display position when moving the underlying image (zooming, panning, etc). After a long while trying to figure out why the handles were doing this I found a solution was to immediately set the world position after a point is placed, using the display position of the point. So for instance, the problem is fixed if I add the following to the end of vtkPointHandleRepresentation2D::SetDisplayPosition() double v[4]; if( this->Renderer ) { vtkInteractorObserver::ComputeDisplayToWorld( this->Renderer, p[0], p[1], p[2], w); this->SetWorldPosition(w); } So is the current behavior desired, or is this a bug? And if it is a bug, does the above code fix it without breaking anything else?
Steps To Reproduce
Additional Information	Behavior identical on Linux (Ubuntu 64-bit) and Windows XP.
