This implements the framework to write the high level rendering code into passes organized in direct acyclic graph. It is also unifying the uniform buffer, shader parameters, and pass parameters to same single API: structures with run time meta data. This allow high level user code be extremely seamless, user code debugging, and render graph ease of implementation and debugging.
Issue of collaborative work of Arne Schnober, Brian Karis, Daniel Wright, Marcus Wassmer and Guillaume Abadie.
Names of the graph managed resources are not final.
