Hi Friends,

I’m using a customized `PlaneWidget` to display and modify interactively the clipping plane used by a `ClipClosedSurface` algo.

The `PlaneWidget` is using a couple of `vtkActor2D` to materialize the handles used to resize/rotate the widget.  
I’m using `Handle->GetPositionCoordinate()->SetCoordinateSystemToWorld()` so that the handles are rendered at the right 3D position, but with a constant screen size (thanks to default `vtkActor2D` behavior).

The problem is that the handles are not taken into account when Resetting the camera position or clipping range.  
I guess this is a normal behavior when using `vtkActor2D` that are displayed relatively to the screen, but in my case I’m placing these actors in world coordinates, and I want the camera to take them into account.

I’ve dug inside VTK source code, namely `ComputeVisiblePropBounds` (vtkRenderer.cxx line 967), and it seams that my 2D actors, despite being displayed, are not inside the `Props` list that is being traversed.

And I can’t figure why … any help ?
