[Paraview-developers] Camera Parallel Projection enable by default

[Pandu tech]

Hi Sebastien,

Thanks for your reply. I tried this and it is working.

Would like to know if there is any way to get this done in Custom
applications (like in my case), without changing ParaView code or paraview
related files.

Thanks,
Pandu.
