From b98613091cd6dc2f914fb5ab38ca33cdff21fc24 Mon Sep 17 00:00:00 2001
From: Dan Lake
Date: Thu, 27 Oct 2011 00:42:21 -0700
Subject: Added new ForEachRootScenePresence to Scene since almost every
 delegate passed to ForEachScenePresence checks for !IsChildAgent first. It
 consolidates child and root handling for coming refactors.
