* Add CommandList.SetBufferData * SpriteBatchSceneObject use CommandLists + make thread safe * Make ScenePanelObject threadsafe * SceneObjects ExecuteOffTheMainThread by default * Remove ExecuteOnMainThread = false, assignments since it's now default * Add Data4 entry to CommandLists allows us to store matrix * Migrate TextRendering to CommandList * Migrate Gizmos to CommandList * Migrate LineRendering to CommandList * ScenePanel uses CommandList * Clutter uses commandlist * Debug SceneObjects use commandlist * Use CommandList.SetBufferData for sprites and lines * Fix SceneLineObject using wrong attribtutes to draw
