[Paraview] LIC surface Color by variable lost on Screenshot with offscreen rendering

[Richard GRENON]

Hello, Utkarsh.

The screenshots I have sent have been made with 
PV-3.10.0-RC1-Linux-x86_64 on CentOS 5.5.

I performed the same screenshot test with PV 3.8.1 on Windows Vista, but 
I had not this color problem, neither the window over picture problem of 
Aurélien Marsan.

I will install PV-3.10.0-RC1 on my Vista laptop and perform the same 
test later.
