[ts] Added 2 color tinting support, made it default, barely a performance difference. You can disable it via the constructors of SceneRenderer, SkeletonRenderer and PolygonBatcher, depending on which level of granularity you use. Also fixed performance issue submitting geometry as STATIC_DRAW instead of DYNAMIC_DRAW. Fixed another performance issue regarding size of buffer data that's being updated.
