// .NAME vtkCompositer - Super class for composite algorthms.
//
// .SECTION Description
// vtkCompositer operates in multiple processes. Each compositer has
// a render window. They use vtkMultiProcessControllers to communicate
// the color and depth buffer to process 0's render window.
// It will not handle transparency well.
//
// .SECTION See Also
// vtkCompositeManager.
