For my prototype that is exactly where I started.  But it didn't work
because it would always complain about the visual s not matching up.
Eventually I just made the renderspu not call SystemMakeCurrent.  That ended
up working but I this solution won't work when there are multiple windows
opening on a display.

The other thing I am trying to accomplish is removing the mothership from
the equation as much as possible.  So passing things to the mothership will
not be very viable. I just want to multiplex the stream out to render nodes.
So the mothership has little configuration to know about.
