[Paraview] state-file does not contain 2D texture if assigned by python

[Cory Quammen]

Hi Roman,

It's not obvious, but you need to register the ImageTexture proxy with the
proxy manager:

pvs.servermanager.Register(texProxy)

Just add that in before you save the state, and you should be good.

HTH,
Cory
