[vtkusers] Synthetic range image generation

I am attempting to create some synthetic range images using VTK. I've
noticed that there is a vtkRenderWindow::GetZ method that will give me the Z
value for a pixel, but I need the scene X and Y coordinates also.
Preferably, I'd like to get the world (X,Y,Z) coordinates for everything.
Is this as simple as multiplying (screenX, screenY, GetZValue) by the
inverse of the ViewTransformMatrix of the current camera, or is there more
involved than this?
