* Added "Display Initialize() Log" admin debug command so you can see it mid-round.
* Ported the core of the overlays management subsystem from /tg
- Added SSoverlays subsystem for compiling overlay lists and applying them to atoms in a controlled anti-lag subsystem.
- Added vars and procs to atom which should eventually replace all direct interaction with BYOND's /atom/overlays var outside the subsystem.
- Added OVERLAY_QUEUED flag to var/atom/flags bitfield.
- Added small framework for subsystem performance tracking. So far used only by SSoverlays
- Added admin debug command "Display overlay Log" to see performance stats mid-round.
* Fix runtime on universal pipe adaptor update_icons
* Workaround for appearance_bro not initialized
Unfortuantely BYOND's initialization order is strange, and the appearance_bro var is only half initialized when map starts to load, causing errors. We temporarily fix by moving it to be a global-scoped global.
* Convert fire alarms to use add_overlay() A good first test.
* Convert turfs to use add_overlays(), eliminating the turf_overlay_holder!
- Converted as much as I could find about turf overlays to use add_overlay().
- This should be enough to stop BYOND from crashing, so we can eliminate the turf_overlay_holder hack.
- This also lets us remove the anti-corruption hacks from walls and open space.
- ZAS gas overlays can use priority overlays, so this also fixes the gas-goes-away-when-crowbarring-plating issue.
- Stuff like that
* Convert turf overlay interactions to use add_overlay.
Note: This is a plain and simple conversion of existing code to use SSoverlays. However I look at the line changed, and note that that line likely never fully worked as intended, as it has no way of re-applying itself.
I would make it use a priority overlay, but there is no code present for *removing* said overlay from neighbors when it is no longer required. That code should be implemented by original author.
* The vast majority of gas mixtures never use their `graphic` list. Prime candidate for making a lazy init list.
* While we are here, add nullchecks to ZAS's use of the graphic list a bit. /turf/update_graphics was technically already null safe, but its even better to not bother calling it at all right?
A simple optimization to can_safely_remove_from_zone() both with and without multi-zas.
Instead of allocating a new list every time we call get_zone_neighbours() (which gets called several times in a loop) we have a pre-built list we don't need to Copy().
Same story for the list to iterate over in can_safely_remove_from_zone()
There should be no semantic change whatsoever from this; it is purely a performance optimization.
slight visual artifact when zones are rebuilt, overlays will be
missing until the end of the current tick. otherwise works fine.

New turf proc: assume_gas(). Maps to air.adjust_gas_temp().
Lots of optimizations to processing, fire, lighting, HasEntered() and
more.
Zones now process all fire data and existance in one go, fire objects
only handle spreading.
Most code has been ported straight so some of it mightn't be ideally
structured for the new gas_mixtures.

Removes del(giver) from pipeline/merge(), turf/assume_air() and
atom/assume_air().
Thanks to valzargaming on reddit/github for pointing it out.
