[vtkusers] Render speed for rendering multiple renderwindows

[Mark Wyszomierski]

Wouldn't it depend on what data you're rendering? I've rendered 16
wins at once when the data was just straight 2D images texture mapped
onto quads. Rendering multiple volumes in different windows at once on
the other hand might be quite the opposite. This has been my experience.
