Ideas to add to the JS API to enable more features:

ActorsAt(Point): query a position in the level and return a list of actors that intersect that point.
- Use case: the Bird can scan for the player character by sampling every 10 pixels diagonally to see if it intersects with a playable character.
CreateActor: dynamically create a new doodad in the level.
- Use case: a turret could spawn bullets, a mob could spawn an Item Bag on death holding its dropped inventory items, etc.
- The created actor would need some way to configure its properties: velocity of a bullet, contents of an item bag, etc. that would be distinct from the usual "static actor placed by the level creator with hard-set doodad tags on it"
- CreateActor could return the Actor and the caller can SetVelocity() etc. on it. An API to "link" the created actor so PubSub events can be sent, or a method to directly call a PubSub handler on an Actor could be useful.
FindActor() or FindPlayer() or NearestPlayer(): locate actors by name or ID or find the player characters.
- Use case: the Snake (#61) wants to face the player always, or mobs could path-find to players, or search the level for actors of interest that a doodad interacts with.

Note: CreateActor not yet tested and will be fleshed out when a doodad starts needing it.
