// .NAME vtkClientServerCompositePass
// .SECTION Description
// vtkClientServerCompositePass is a render-pass that can handle client-server
// image delivery. This is designed to be used in configurations in
// two-processes configurations.

// If it is NULL, nothing will be rendered and a warning will be emitted.
// Initial value is a NULL pointer.

// server side.

// Description:
// Set/Get the optional post-fetch render pass.
// On the client-process this is called after the server-side image is fetched
// (if ServerSideRendering is true). On server-process, this is called after the
// image rendered by this->RenderPass is delivered to the client (if
// ServerSideRendering is true). This is optional, so you can set this either on
// one of the two processes or both or neither.
void SetPostProcessingRenderPass(vtkRenderPass*);

// and which one is the client.
