[Paraview] Adding a renderer to ParaView

[Joel Welling]

Hi folks;
  I'm trying to add a Chromium renderer to ParaView, based on David Thompson 
et al.'s Chromium renderer for vtk and using the vtkPVIceTRenderModule as an 
example.  I have a few questions.

- Is there any documentation as to how all of these parts are supposed to work 
together?

- Is there a way to get the class hierarchy for the various renderer types?

- For a renderer named Foo, what are the purposes of the separate 
vtkPVFooRenderModule, vtkPVFooDisplayRenderModule, vtkPVFooRenderModuleUI, and 
vtkPVFooDisplayRenderModuleUI classes, and are all of them required?

- Should code for a new renderer be added to the Servers/Filters, 
Servers/ServerManager, and GUI/Client directories, or should it somehow be 
kept separate and linked in via cmake cleverness?

Thanks for your patience.
