Title: Instancing GLGroups at scene links

I've got 60% increase in performance in the playback of our crowd scene (700 animated characters) by recognizing the locations where there are links in a LinkedScene file which map to exactly the same time and avoiding re-rendering the branches each time, by creating maps of instances, that at the end of the rendering, is used to duplicate the GL groups into each instanced location.
