Actors' tags and components usually remain constant throughout the game, but currently, wh-engine still checks the tags of every actor, every frame.

I could speed up the performance of the rendering system (and future systems) by sorting actors into groups by their tags. Then, wh-engine would only have to process the actors inside the buckets it's interested in, skipping the (some (lambda (x) [actor (has-tag x)]) tag-list) nonsense entirely.

This would make changing actors' tags somewhat slower, but that's an acceptable tradeoff.

Bucketing by tag
Component bucketing (components of a certain type attached to actors with the desired tags)
- Maybe maintain a second bucket without the tag requirements, so wh-engine only has to search that list if the tag mask changes
