// .NAME vtkDesktopDeliveryClient2 - An object for remote rendering.
// .SECTION Caveate
// This class uses image actor to display the final image. The original
// vtkDesktopDelivery used SetPixelData which was slower. This class could be
// cleaned up to remove duplicate code from the superclass, but I might just
// modify vtkClientCompositeManager instead.
// .SECTION Description
// The two vtkDesktopDelivery objects (vtkDesktopDeliveryClient2 and
// vtkDesktopDeliveryServer) work together to enable interactive viewing of
// remotely rendered data. The client attaches itself to a vtkRenderWindow
// and, optionally, a vtkRenderWindowInteractor. Whenever a new rendering
// is requested, the client alerts the server, the server renders a new
// frame, and ships the image back to the client, which will display the
// image in the vtkRenderWindow.
// .SECTION note
// You should set up the renderers and render window interactor before setting
// the render window. We set up observers on the renderer, and we have no
// easy way of knowing when the renderers change.
// .SECTION see also
// vtkDesktopDeliveryServer vtkMultiProcessController vtkRenderWindow
