[vtkusers] Select/Deselect actors

[David Doria]

>> Does anyone knows if there's a method to select/deselect all actors
>> associated to an interactor?

#include <vtkRendererCollection.h>
#include <vtkActorCollection.h>
vtkActorCollection* allActors =
interactor->GetRenderWindow()->GetRenderers()->GetFirstRenderer()->GetActors()

Then use VisibleOff() that Jothy selected on each actor in the
collection. Read more here:
