[sldev] Why does the simulator do object culling for clients?

[John Hurliman]

As you move around in a simulator, the sim is constantly sending 
ObjectUpdate* packets for objects that become within range or have 
moved, and it sends ObjectKill packets for things that go outside of 
your vision. Then when you move back to that area it sends the 
ObjectUpdate* packets for those objects again. Is there a reason this 
culling is done across the network by sending ObjectKill packets for 
things that are not actually leaving the simulator?
