This I know.  I am not using Chromium like most though. I am trying to
insert crServer into a frame loop that I don't have much control over(VR
Juggler).

If your app calls [glX/wgl]SwapBuffers() you can intercept that in

This is what I was asking. I want to intercept these in the server stream,
not in an SPU. Is anything like this supported/can I make it happen?
