// .NAME vtkTreeCompositer - Implements tree based compositing.
//
// .SECTION Description
// vtkTreeCompositer operates in multiple processes.  Each compositer has
// a render window.  They use a vtkMultiProcessController to communicate
// the color and depth buffer to process 0's render window.
// It will not handle transparency well.
