[Paraview] WriteImage Arguments

[Andy Bauer]

I just pushed a change to next. Besides the default value, I also made a
change to the source code since if the magnification was greater than 1 it
would change the view. Utkarsh, do you mind checking that the change for
this is proper?  The branch name is 13320_default_view_magnification.
