// .NAME vtkImageRenderManager - An object to control sort-first parallel rendering.
//
// .SECTION Description:
// vtkImageRenderManager is a subclass of vtkParallelRenderManager that
// uses RGBA compositing (blending) to do parallel rendering.
// This is the exact opposite of vtkCompositeRenderManager.
// It actually does nothing special. It relies on the rendering pipeline to be
// initialized with a vtkCompositeRGBAPass.
// Compositing makes sense only for renderers in layer 0.
// .SECTION See Also
// vtkCompositeRGBAPass
