Does OpenGLRenderer support particle flags?

Hi,
I implemented a particle emitter. I am using particle flags to start emissions at each frame.
However, during rendering all the particles are rendered regardless of their flags. Is there a way to not render inactive particles?
Thanks

Now that we are using the new Viewer(GL) implementation in Newton rather than OpenGLRenderer we can probably implement this soon. I will create an issue out of this discussion.
