[Paraview] ParaviewWeb 4 - WebGL renderer camera reset and background issue

[Albrecht Kyrieleis]

Hi Bogdan,
I want to use WebGl with paraviewWeb 4 and JettySessionManager. So far I am
using the PV binary and have defined my own protocol that works fine. At
which places in the setup do you have to do alterations to get webgl
rendering running ? Where can I get more information on that ?

Many thanks,

Kyr
