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.

# gltf_cached.ludic - a still model loaded once: the same (dir, file, node) asked again hands back the
|

# model the first load made, found by comparing the names in place, so asking allocates nothing. For
|
|
# props a game places while it plays (a fish, a sign an animal leaves); a model whose document is
|
|
# read after the load (ludic.anim's clips) still goes through gltf_load. A model loaded here is shared
|
|
# by every actor drawing it; model_release takes it out of the cache as it lets it go.
