I'm trying to learn how to do two-pass drawing in performer.
Does the following seem reasonable or are there better ways?

my_draw() {

preDrawStuff();

pfDraw();

intermediateDrawStuff();

pfDraw();

postDrawStuff();

}

Then register my_draw with the pfChannel using

channel->setTravFunc(PFTRAV_DRAW, my_draw);

Thank you,
