[Paraview] default representation?

[Cory Quammen]

Bertwim,

Ken is right, the default representation is chosen by the view in
which the source output is displayed. See, for instance,

ParaView/ParaViewCore/ServerManager/Rendering/vtkSMRenderViewProxy::GetRepresentationType()

for the logic used to pick the default representation used in the 3D View.
