[vtkusers] Rendering at lower resolution than vtkRenderWindows size?

[Krzysztof Kamieniecki]

Hi,

Is there an easy/approved way to configure vtkRenderWindow so that the
every vtkProp renders at a lower resolution then the actual window size? I
am working on a new stereo mode, and I have to render the scene about 10
times and then combine the results into the final displayed image. Since
each image is 10 times smaller I hope to get back most if not all of the
original render speed.

Thanks,
Krys
