/**
* @class vtkCompositeZPass
* @brief Merge depth buffers of processes.
*
* 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.
