// .NAME vtkCompositeZPass - Merge depth buffers of processes.
// .SECTION Description
// Merge the depth buffers of satellite processes into the root process depth
// buffer. It assumes that all the depth buffers have the same number of bits.
// The depth buffer of the satellite processes are not changed.
//
// This pass requires a OpenGL context that supports texture objects (TO),
// and pixel buffer objects (PBO). If not, it will emit an error message
// and will render its delegate and return.
//
