+ * Decorative items for PoIs etc.
+ * These are generally sprites ported from other servers, which don't have any unique code.
+ * They can be used by mappers for decorating their maps. They're mostly here so people who aren't
+ * rummaging around in the sprites can be aware of some neat sprites they can use.
+ *
+ * Obviously you can swipe the sprites for real structures and add code, but please don't add any code
+ * (beyond decorative things like maybe light) directly to these types or this file!
+ * Take the icon and state and make your own type under /obj/structure.
+ *
+ * Some of these do have a SMIDGE of code to allow a mapper to twirl them through states/animations without
+ * much effort, but beyond 'visuals logic', I'd rather keep all the logic out of here.

+ Notes on change_state
+ *
+ * tl;dr "You can varedit 'state' on these to the things in the comments below to get cool animations"
+ *
+ * These items have some logic to handle some fun animations on them. Mappers can call the 'change_state(state)' proc
+ * while referring to the comments here for what states they can use. You'll notice some crazy overlay handling,
+ * and that's because I don't want to add any vars to these mappers think they can fiddle with, which requires
+ * more logic than I'm willing to do at the moment. So we get crazy cut/add operations instead.
+ *
+ * There's also a VV helper so if you varedit 'state' to these during the game, you can get that to work.
+ *
+ * Like, I don't want to add a state machine to decorative objects. You can if you want.
