Detailed Description

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.
