/**
 * @class   vtkImageRenderManager
 * @brief   An object to control sort-first parallel rendering.
 *
 *
 * 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.
 * @sa
 * vtkCompositeRGBAPass
