Subject: Parameterizes the view distance used to compute and manage child
agents in neighbor regions. This means you can extend the view on a simulator
beyond the default 3x3 regions.
This uses a region default draw distance and should be
replaced at some point by the avatar specified draw distance.
That will require more careful, dynamic recomputation of child
agents every time the draw distance changes.
WARNING: this is experimental and has known instabilities. specifically
all regions "within site" should be running the same default draw distance
or agents will not be closed correctly.
