Detailed Description

This is a static class that reproduces some of the functionality of G3D::System for use specifically in clustered rendering environments. For example, when doing animation based on the system's clock you want the time to be the same across all the rendering nodes, so you can't use System::getLocalTime() because it will be slightly off between the various nodes. Instead, use SynchedSystem::getLocalTime() and the value for time will be the same across all walls, although, it will only be as accurate as the rate at which the time is updated from the vrg3d event server, which will be once per frame.
