Thanks for bringing this function to my attention, I was able to add another
origin point to the PVS system however i still get some minor flickers. I'd
still like to find a way to enter individual entities into the list of
displayed entities, clientside if possible, since theres no possible
cheating that can be done by displaying the entity I want.
