When you open a new window, it gets a number.  (This is shown in the 
title in Windows. I forget whether other platforms display it, but it's 
in the return value of open3d()/rgl.open() and rgl.cur().)  You can 
choose to add more to an existing device using rgl.set().  You can clear 
items from a device using rgl.clear() or rgl.pop().
