[Paraview] Scaling up 3-D area in screenshots

[Tim Gallagher]

The RenderView.CameraParallelScale does it I believe. At least, that's what popped out of my trace awhile back and it seems to zoom in.

Thanks, thats been my modus operandi until now, and it appears that the 
"view" variables for the camera viewpoint
are whats needed; they are the only ones listed as changed in the 
trace.  But no matter how I change them in the script, it still seems to 
take up the middle half of the image only (i am appending screenshots to 
make an animation, and its very annoying).
