Well, I believe what I want to do is the equivalent of culling the

every frame that I don't have an update to the texture. I can do

placing a switch above the camera node, but was hoping for something
similar to a
dirty bit or enable/disable bit.
You could implement things in a variaty of ways, from implment a
custom callback to switch the node on of off, through to even hiding
the use of the camera completely, such as what osgSim::OverlayNode
does.
I am doing all of my operations directly on the "frame buffer
object" aka texture.
If I switch to FRAME_BUFFER mode then I need to render the current
texture contents
before rendering my updates.
You've lost me.
