SIMの境界で，座標な不正になった場合に，強制的に emergencyPos [すなわち(128,128,128)] へ移動させられる件

上記の様に変更した場合，CrossToNewRegion() でエラーが出る場合があるので修正する．

OpenSim/Region/Framework/Scenes/ScenePresence.cs

CrossToNewRegion()

/// <summary>
/// Moves the agent outside the region bounds
/// Tells neighbor region that we're crossing to it
/// If the neighbor accepts, remove the agent's viewable avatar from this scene
/// set them to a child agent.
/// </summary>
protected void CrossToNewRegion()
{
    // Fumi.Iseki
    if (m_scene==null || m_physicsActor==null) return;
    InTransit();
    m_scene.CrossAgentToNewRegion(this, m_physicsActor.Flying);
}
