implemented the new mode for an auto stereoscopic display and this mode is
based on sub-pixel multiplexing the image. Everything looks fine on the
implementation as it was quite straightforward.</span></p>

resizing the window causes the result to interpolate and of course it destroys
completely the stereo format I want to use. I also noticed that further
resizing the window causes the whole application Paraview to crash.</span></p>
