View encapsulates the set of entities currently visible to an Avatar, as well as those that have recently been seen. It receives visibility-affecting ops from the IGRouter, and uses them to update its state and emit signals.

Method to register and unregister tasks with with view, so they can have their progress updated automatically by update(). Only certain tasks (those with linear progress) are handled this way, but all tasks are submitted to this method.

void Eris::View::update | ( | ) |
once-per-frame update of the View - clients should call this method once per game loop (or similar), to allow the View to update Entity state. This includes motion prediction for moving entities, and confidence levels for disappeared entities.
