[vtkusers] vtkCaptionActor2D always drawn on top of everything else ?

Nope -- vtkCaptionActor2D renders in the overlay, which will always
occlude 3D geometry.

You may want to try vtkBillboardTextActor3D, which was recently added.
It doesn't do quite the same thing as the caption actor, but will mix
with 3D geometry.
