A freed texture or buffer id goes on a spare list the next one takes; tex_note_size keeps sizes by id. model_release frees prims, meshes, material names, the skin and leaves gltf_cached. actor_release takes an actor off the stage and actor_new reuses its record (ECS's Things come and go all day). steady.ludic: an actor round at 0 bytes over 2000.
