// .NAME vtkCompressCompositer - Implements compressed tree based compositing.
//
// .SECTION Description
// vtkCompressCompositer operates in multiple processes. Each compositer has
// a render window. They use vtkMultiProcessController to communicate
// the color and depth buffer to process 0's render window.
// It will not handle transparency. Compositing is run length encoding
// of background pixels.
//
// SECTION See Also
// vtkCompositeManager.
