[vtkusers] Annotating an image with text

[Jérôme]

You can use SetPosition in vtkTextActor to place a string everywhere in the
image. For file writing, why not using vtkWindowToImageFilter?

BTW, I sent a mail mentioning a segfault caused by vtkTextActor ("vtkTextActor
segfaults my render window"). Did you try to use it? Am I the only one?
