[Bf-cycles] Idea for collaboratory rendering (multiple rendering machines on a sigle frame)

This can be a useful way to do things, in fact renderfarm.fi can
already work this way I think (the seed value was originally added on
their request). Any render farm software like netrender or brender
could implement this, currently they still don't support multiple
slaves cooperating on one frame though. I'm not sure if this is
necessarily simpler than tile based rendering, from the implementation
point of view it does not seem much easier, and there's the issue that
renders will not give the exact same results due to different random
numbers being used.

In any case, when we are talking about interactive network rendering
built into cycles itself, then tiles would still be the easiest
solution since it already distributes things that way across CPU cores
and GPU's, and combining the render results is not really the hard
part of the implementation anyway.
