23bfdec8f4 Multiz Rework: Human Suffering Edition (Contains PLANE CUBE) (#69115)
About The Pull Request

I've reworked multiz. This was done because our current implementation of multiz flattens planes down into just the openspace plane. This breaks any effects we attach to plane masters (including lighting), but it also totally kills the SIDE_MAP map format, which we NEED for wallening (A major 3/4ths resprite of all wall and wall adjacent things, making them more then one tile high. Without sidemap we would be unable to display things both in from of and behind objects on map. Stupid.)

This required MASSIVE changes. Both to all uses of the plane var for reasons I'll discuss later, and to a ton of different systems that interact with rendering.

I'll do my best to keep this compact, but there's only so much I can do. Sorry brother.
Core idea

OK: first thing.
vis_contents as it works now squishes the planes of everything inside it down into the plane of the vis_loc.
This is bad. But how to do better?

It's trivially easy to make copies of our existing plane masters but offset, and relay them to the bottom of the plane above. Not a problem. The issue is how to get the actual atoms on the map to "land" on them properly.

We could use FLOAT_PLANE to offset planes based off how they're being seen, in theory this would allow us to create lens for how objects are viewed.
But that's not a stable thing to do, because properly "landing" a plane on a desired plane master would require taking into account every bit of how it's being seen, would inherently break this effect.

Ok so we need to manually edit planes based off "z layer" (IE: what layer of a z stack are you on).

That's the key conceit of this pr. Implementing the plane cube, and ensuring planes are always offset properly.
Everything else is just gravy.
About the Plane Cube

Each plane master (except ones that opt out) is copied down by some constant value equal to the max absolute change between the first and the last plane.
We do this based off the max z stack size detected by SSmapping. This is also where updates come from, and where all our updating logic will live.

As mentioned, plane masters can choose to opt out of being mirrored down. In this case, anything that interacts with them assuming that they'll be offset will instead just get back the valid plane value. This works for render targets too, since I had to work them into the system as well.

Plane masters can also be temporarily hidden from the client's screen. This is done as an attempt at optimization, and applies to anything used in niche cases, or planes only used if there's a z layer below you.
About Plane Master Groups

BYOND supports having different "maps" on screen at once (IE: groups of items/turfs/etc)
Plane masters cannot cover 2 maps at once, since their location is determined by their screen_loc.
So we need to maintain a mirror of each plane for every map we have open.

This was quite messy, so I've refactored it (and maps too) to be a bit more modular.

Rather then storing a list of plane masters, we store a list of plane master group datums.
Each datum is in charge of the plane masters for its particular map, both creating them, and managing them.

Like I mentioned, I also refactored map views. Adding a new mapview is now as simple as newing a /atom/movable/screen/map_view, calling generate_view with the appropriate map id, setting things you want to display in its vis_contents, and then calling display_to on it, passing in the mob to show ourselves to.

Much better then the hardcoded pattern we used to use. So much duplicated code man.

Oh and plane master controllers, that system we have that allows for applying filters to sets of plane masters? I've made it use lookups on plane master groups now, rather then hanging references to all impacted planes. This makes logic easier, and prevents the need to manage references and update the controllers.

image

In addition, I've added a debug ui for plane masters.
It allows you to view all of your own plane masters and short descriptions of what they do, alongside tools for editing them and their relays.

It ALSO supports editing someone elses plane masters, AND it supports (in a very fragile and incomplete manner) viewing literally through someone else's eyes, including their plane masters. This is very useful, because it means you can debug "hey my X is yorked" issues yourself, on live.

In order to accomplish this I have needed to add setters for an ungodly amount of visual impacting vars. Sight flags, eye, see_invis, see_in_dark, etc.

It also comes with an info dump about the ui, and plane masters/relays in general.

Sort of on that note. I've documented everything I know that's niche/useful about our visual effects and rendering system. My hope is this will serve to bring people up to speed on what can be done more quickly, alongside making my sin here less horrible.
See https://github.com/LemonInTheDark/tgstation/blob/multiz-hell/.github/guides/VISUALS.md.
"Landing" planes

Ok so I've explained the backend, but how do we actually land planes properly?
Most of the time this is really simple. When a plane var is set, we need to provide some spokesperson for the appearance's z level. We can use this to derive their z layer, and thus what offset to use.

This is just a lot of gruntwork, but it's occasionally more complex.
Sometimes we need to cache a list of z layer -> effect, and then use that.
Also a LOT of updating on z move. So much z move shit.

Oh. and in order to make byond darkness work properly, I needed to add SEE_BLACKNESS to all sight flags.
This draws darkness to plane 0, which means I'm able to relay it around and draw it on different z layers as is possible. fun darkness ripple effects incoming someday

I also need to update mob overlays on move.
I do this by realiizing their appearances, mutating their plane, and then readding the overlay in the correct order.

The cost of this is currently 3N. I'm convinced this could be improved, but I've not got to it yet.
It can also occasionally cause overlays to corrupt. This is fixed by laying a protective ward of overlays.Copy in the sand, but that spell makes the compiler confused, so I'll have to bully lummy about fixing it at some point.
Behavior changes

We've had to give up on the already broken gateway "see through" effect. Won't work without managing gateway plane masters or something stupid. Not worth it.
So instead we display the other side as a ui element. It's worse, but not that bad.

Because vis_contents no longer flattens planes (most of the time), some uses of it now have interesting behavior.
The main thing that comes to mind is alert popups that display mobs. They can impact the lighting plane.
I don't really care, but it should be fixable, I think, given elbow grease.

Ah and I've cleaned up layers and plane defines to make them a bit easier to read/reason about, at least I think.

e5a2b0f16e Micros the lighting subsystem (Saves a second of init) (#69838)
About The Pull Request

Micros lighting objects, and their creation

We save a good bit of time by not walking space turfs adjacent to new objects.
We also save some time with micros in the actual underlay update logic.

I swear dude we spend like 0.8 seconds of init applying the underlay. I want threaded maptick already

Micros lighting sources, and corner creation

A: Corners were being passed just A turf, and then expected to generatecorners based on that. This is pointless.
It is better to instead pass in the coords of the bottom left turf, and then build in a circle. This saves like 0.3 seconds

B: We use so many damn datum vars in corner application that we just do not need to.
This resolves that, since it pissed me off. It's pointless. Lets cache em instead

There's some misc datum var caching going on here too. Lemme see...
Oh and a bit of shortcutting for a for loop, since it was a tad expensive on its own.

Also I removed the turfs list, because it does fucking nothing. Why is this still here.

All my little optimizations save about 1 second of init I think
Not great, but not bad, and plus actual lighting work is faster now too

About The Pull Request

fixes #66887

done for the code bounty posted by @MMMiracles to optimize the tram so that it can be sped up. the tram is now twice as fast, firing every tick instead of every 2 ticks. and is now around 10x cheaper to move. also adds support for multiz trams, as in trams that span multiple z levels.

the tram on master takes around 10-15 milliseconds per movement with nothing on it other than its starting contents. why is this? because the tram is the canary in the coal mines when it comes to movement code, which is normally expensive as fuck. the tram does way more work than it needs to, and even finds new ways to slow the game down. I'll walk you through a few of the dumber things the tram currently does and how i fixed them.

    the tram, at absolute minimum, has to move 55 separate industrial_lift platforms once per movement. this means that the tram has to unregister its entered/exited signals 55 times when "the tram" as a singular object is only entering 5 new turfs and exiting 5 old turfs every movement, this means that each of the 55 platforms calculates their own destination turfs and checks their contents every movement. The biggest single optimization in this pr was that I made the tram into a single 5x11 multitile object and made it only do entering/exiting checks on the 5 new and 5 old turfs in each movement.
    way too many of the default tram contents are expensive to move for something that has to move a lot. fun fact, did you know that the walls on the tram have opacity? do you know what opacity does for movables? it makes them recalculate static lighting every time they move. did you know that the tram, this entire time, was taking JUST as much time spamming SSlighting updates as it was spending time in SStramprocess? well it is! now it doesnt do that, the walls are transparent. also, every window and every grille on the tram had the atmos_sensitive element applied to them which then added connect_loc to them, causing them to update signals every movement. that is also dumb and i got rid of that with snowflake overrides. Now we must take care to not add things that sneakily register to Moved() or the moved signal to the roundstart tram, because that is dumb, and the relative utility of simulating objects that should normally shatter due to heat and conduct heat from the atmosphere is far less than the cost of moving them, for this one object.
    all tram contents physically Entered() and Exited() their destination and old turfs every movement, even though because they are on a tram they literally do not interact with the turf, the tram does. also, any objects that use connect_loc or connect_loc behalf that are on the same point on the tram also interact with each other because of this. now all contents of the tram act as if theyre being abstract_move()'d to their destination so that (almost) nothing thats in the destination turf or the exit turf can react to the event of "something laying on the tram is moving over you". the rare things that DO need to know what is physically entering or exiting their turf regardless of whether theyre interacting with the ground can register to the abstract entered and exited signals which are now always sent.
    many of the things hooked into Moved(), whether it be overrides of Moved() itself, or handlers for the moved signal, add up to a LOT of processing time. especially for humans. now ive gotten rid of a lot of it, mostly for the tram but also for normal movement. i made footsteps (a significant portion of human movement cost) not do any work if the human themselves didnt do the movement. i optimized has_gravity() a fair amount, and then realized that since everything on the tram isnt changing momentum, i didnt actually need to check gravity for the purposes of drifting (newtonian_move() was taking a significant portion of the cost of movement at some points along the development process). so now it simply doesnt call newtonian_move() for movements that dont represent a change in momentum (by default all movements do).

also i put effort into 1. better organizing tram/lift code so that most of it is inside of a dedicated modules folder instead of scattered around 5 generic folders and 2. moved a lot of behavior from lift platforms themselves into their lift_master_datum since ideally the platforms would just handle moving themselves, while any behavior involving the entire lift such as "move to destination" and "blow up" would be handled by the lift_master_datum.

multiz tram (this just adds the capability to map it like this, no tram does this)
Actual Performance Differences

to benchmark this, i added a world.Profile(PROFILER_START) and world.Profile(PROFILER_START) to the tram moving, so that it generates a profiler output of all tram movement without any unrelated procs being recorded (except for world.Profile() overhead). this made it a lot easier to quantify what was slowing down both the tram and movement in general. and i did 3 types of tests on both master and my branch.

also i should note that i sped up the "master" tram test to move once per tick as well, simply because the normal movement speed seems unbearably slow now. so all recorded videos are done at twice the speed of the real tram on master. this doesnt affect the main thing i was trying to measure: cost for each movement.

the first test was the base tram, containing only my player mob and the movables starting on the tram roundstart. on master, this takes around 13 milliseconds or so on my computer (which is pretty close to what it takes on the servers), on this branch, it takes between 0.9-1.3 milliseconds.

ALSO in these benchmarks youll see that tram/proc/travel() will vary significantly between the master and optimized branches. this is 100% because there are 55 times more platforms moving on master compared to the master branch, and thus 55x more calls to this proc. every test was recorded with the exact same amount of distance moved

here are the master and optimized benchmark text files:

also this shows the increased SSlighting usage resulting from the tram on master spamming updates, which doesnt happen on the optimized branch

the second test is meant to benchmark the best case scaling cost of moving objects, where nothing extra is registered to movement besides the bare minimum stuff on the /atom/movable level. Each of the open tiles of the tram had 1 bluespace rped filled with parts dumped onto it, to the point that the tram in total was moving 2100 objects. the vast majority of these objects did nothing special in movement so they serve as a good base case. only slightly off due to the rped's registering to movement.

on master, this test takes over 100 milliseconds per movement

optimization 2000 obj's.txt

the third test is 300 humans spawned onto the tram, meant to test all the shit added on to movement cost for humans/carbons. in retrospect this test is actually way too biased in favor of my optimizations since the humans are all in only 3 tiles, so all 100 humans on a tile are reacting to the other 99 humans movements, which wouldnt be as bad if they were distributed across 20 tiles like in the second test. so dont read into this one too hard.

on master, this test takes 200 milliseconds

Why It's Good For The Game

the tram is literally 10x cheaper to move. and the code is better organized.
currently on master the tram is as fast as running speed, meaning it has no real relative utility compared to just running the tracks (except for the added safety of not having to risk being ran over by the tram). now the tram of which we have an entire map based around can be used to its full potential.

also, has some fixes to things on the tram reacting to movement. for example on master if you are standing on a tram tile that contains a banana and the TRAM moves, you will slip if the banana was in that spot before you (not if you were there first however). this is because the banana has no concept of relative movement, you and it are in the same reference frame but the banana, which failed highschool physics, believes you to have moved onto it and thus subjected you to the humiliation of an unjust slipping. now since tram contents that dont register to abstract entered/exited cannot know about other tram contents on the same tile during a movement, this cannot happen.

also, you no longer make footstep sounds when the tram moves you over a floor
TODO

mainly opened it now so i can create a stopping point and attend to my other now staling prs, we're at a state of functionality far enough to start testmerging it anyways.

add a better way for admins to be notified of the tram overloading the server if someone purposefully stuffs it with as much shit as they can, and for admins to clear said shit.
automatically slow down the tram if SStramprocess takes over like, 10 milliseconds complete. the tram still cant really check tick and yield without introducing logic holes, so making sure it doesnt take half of the tick every tick is important
go over my code to catch dumb shit i forgot about, there always is for these kinds of refactors because im very messy
remove the area based forced_gravity optimization its not worth figuring out why it doesnt work
fix the inevitable merge conflict with master lol
create an icon for the tram_tunnel area type i made so that objects on the tram dont have to enter and exit areas twice in a cross-station traversal

    add an easy way to vv tram lethality for mobs/things being hit by it. its an easy target in another thing i already wanted to do: a reinforced concept of shared variables from any particular tram platform and the entire tram itself. admins should be able to slow down the tram by vv'ing one platform and have it apply to the entire tram for example.

Changelog

cl
balance: the tram is now twice as fast, pray it doesnt get any faster (it cant without raising world fps)
performance: the tram is now about 10 times cheaper to move for the server
add: mappers can now create trams with multiple z levels
code: industrial_lift's now have more of their behavior pertaining to "the entire lift" being handled by their lift_master_datum as opposed to belonging to a random platform on the lift.

a6d4e180ad Adds a visualizer for lighting object updating. Optimizes the same (#67678)
It occured to me, we didn't have a good way to "see" what turfs were actually being updated
Figured I'd fix that

I've also added some debug vars on SSlighting to make testing with/without some checks easier

Speaking of which, I've added a second check to lighting corner updating
Basically, if our past and current cached rgb values are the same, there's no point updating

This is possible because static lighting is relative. If you've got a
TON of blue, it'll outweight the red and green you have in smaller amounts

We also do some rounding to ensure values look right

Similarly, if you've got roughly the same lighting, and a bit of something you already have a lot of is added, you're not likely to actually enter a new "bracket" of color

Anyway uh, it's hard to profile this, but I've seen it help quite a bit, mostly with things like emergency lighting that updates lighting in small amounts often, and in constricted spaces.

To some extent just comes down to map design

cbc6f35f54 Things that love the station may no longer leave the station, even when Dr. Anomaly says they should. (#61335)
Bluespace anomalies detonating Move() things. When something is Move()d, none of the logic in forceMove() or doMove() is called, and thus stationloving things can't tell when they've left the z-level (since that's where the logic for it is).

There are a number of approaches I could have taken: Refactoring anomalies to use different movement code. Refactoring Movement code to send more signals in various scenarios. Refactoring the stationloving component.

I settled on two steps. First, refactoring the component to bring it up to modern code standards. Second, moving the logic for COMSIG_MOVABLE_Z_CHANGED to Moved() so the signal always fires regardless of if Move() or forceMove() or doMove() is used, with an optional var for whether the z-change is communicated to contents. This means the ore box was changed to actually send the signal instead of just returning with no parent call or signal sent. Stationloving ore boxes when?

stationloving procs no longer call SIGNAL_HANDLERs directly. Var names are now more descriptive. Things are renamed and documented. At least for the parts of the code I know.

Probably some other code cleanups.

d3a1bea859 Turns lighting objects into a datum, makes all lighting be performed with an underlay. big maptick fix very good! (#58991)
credit to zewaka for the idea of using underlays

turns the lighting object movables that were unnecessary and increased maptick into a datum which then applies and removes an underlay in update(). also applies a lot of general lighting clean ups (mostly using as anything in loops and fixing single letter var names).

multiz is a little different by necessity, now only the bottom turf's lighting matters in the brightness of the top turf unlike master where the bottom turf's lighting object is hidden from the vis_contents of the top turf. there are still some kinks to iron out here though, since currently objects suspended in openspace (like tram platforms) look bad and glass floors look bad too

only thing i have left to do is make multiz work (well)

UPDATE: multiz now appears the same as far as i can tell, its possible there are other situations in which its different but datum mats work and it automatically updates if the turf below changes. now i just need to make the system less finnicky if at all possible (and possibly merge managed_turf_vis_content with managed_overlays maybe?)

new update: its basically equivalent to normal multiz as far as i can tell (visually at least, in the circumstances ive tested so far)

NEW NEW UPDATE: turfs no longer have the VIS_HIDE vis_flag and multiz works without stacking the lighting from the floor below! so this shouldnt have any overt drawbacks to master anymore

1 needless movable per tile is terrible for maptick. this is probably a larger improvement than my emissive blocker change in terms of maptick. im guessing we'd get around 0.6 average maptick per player after this where currently we get 0.85 or so

Edit: according to lemon, sybil reached 0.71 maptick per person when tm'd with this

if this is a big enough improvement i might finally be able to get rid of the Gone discord avatar

e0c3019dc3 [READY] Lighting list cleanup. (#59002)
Removed a bunch of back reference lists that were either entirely unused, or contained references that could be found within the datums contained in other lists.

lighting corner datums now get deleted with unused.

light sources no longer track lighting corners where the appiled light rounds to 0.

Fix lighting on turfs that gained dynamic lighting mid round. lazy init corner datums.

these two are related. by decoupling corner datums from the turfs dynamic lighting state, we can use them to know what level of light a non-dynamic light turf should have once it gains dynamic light.

Also should free up some memory not storing these datums in maint. Corner datums only exist on a turf that has light cast upon it by the dynamic lighting system.

Lighting corners are now lazy inited and deleted. they should always (and only exist) if there is a light source shining on it within range (even if the turf has no dynamic lighting). This is needed to support turfs that become lighting enabled mid round. On the plus side, they will no longer be generated on full dark turfs.

03164f4fcb Emissive system refactor (#58130)
The emissives system is the system that both lets computer screens and vendors glow in the dark and lets mobs and items block those glows. The current implementation relies on using filters to let mobs and items mask out the glow in the dark overlays on some structures. This is difficult to extend properly without massively increasing maptick. This PR changes the emissives system to use BYONDs native image layering to mask emissive overlays. This should prove to be a more extensible option.

tldr; There exists a system that lets computer screens glow on the dark and lets mobs and items block the glow. It isn't very extensible and this PR attempts to make it more extensible.

How emissive overlays used to work

Currently emissive overlays and the emissive blockers that mask those overlays are handled using a system of inter-masking planes. The emissive overlays and the emissive blockers are placed on separate, hidden plane masters. These are essentially rendering layers and groups. The emissive blocker plane is then used to mask the emissive overlay plane which effectively allows the emissive blockers to block the emissive overlays from being seen. After is has been masked the emissive overlay plane is used to mask the lighting plane, essentially creating holes in the shadows wherever an unblocked glowing thing exists.

Why this is a potential problem

This system works fine. In fact it works great! The computer screens glow, any person or item that winds up on a computer blocks the glow, and everything just works. However, this system runs into some issues when you try to extend it to work on things other than structures. Namely, the current system only supports emissive overlays on structures and emissive overlays that are completely unblockable by any means. As a result, several interesting uses to the system require extending the system.

As a result, if you want to apply emissive overlays to items (which exist between structures and mobs) or emissive overlays to turfs (which exist below structures) you must extend the emissives system to get the emissive overlays and emissive blockers to properly function. Doing this naively, by adding extra emissive overlay and emissive blocker planes and applying all of the relevant masking filters, is not exactly performant.

Maptick is a major contributor to lag and the higher the maptick the more free lag you, the player, get delivered fresh to your client. Trying the naive method resulted in #55782 (1f1b58bb26), an attempt to add glowing carpet to the game. Since the PR revolved around adding glowing carpet it had to extend the emissives system to allow for emissive turfs and emissive blocking structures. Extending the system was done naively as described above and you can see the results. 1.5 times the maptick across the board. Ouch.

So, we know that extending the system in it's current form is impractical. At least if done naively. Thus we are stuck.

tldr; The emissive system currently uses inter-plane masking to allow for emissive blockers to function. This is difficult to reasonably extend without murdering maptick. See #56496 (1f1b58bb26) for the results of naively extending this system.

How emissive overlays are going to work

Alright, so we know that the current system of using planes to let the emissive blockers mask the emissive overlays is difficult to extend in it's current form. The solution is to change how the system works so that it can be extended in a more efficient manner. What we want is a system that allows one set of images to be out masked by another set of images and for the first set of images to be capable of masking the light plane. Preferably, we would also like the ability to interleave the masking effect between emissives and emissive blockers with almost arbitrary layering.

Conveniently, this layering and masking is something BYOND already does to normal items and objects. If we put the emissive overlays and the emissive blockers on the same plane we can use their layers to interleave them almost arbitrarily like any normal structures and items! All we need is a way to mask away the emissive blockers from the resulting rendered plane and we can mask the lighting plane with the remaining emissive overlays.

Luckily, BYOND has provided a single filter that is capable of this task. The color matrix filter. This filter can be used to apply a color matrix to an image! Provided that the emissive overlays and the emissive blockers are different colors we can use a color matrix filter to effectively mask out the emissive blockers from the plane! The resulting emissive plane can be applied as an alpha mask to the lighting plane as it used to, to the same effect. The best part is, we get layering practically for free!

This is exactly what this PR does. It converts the emissives system from the old plane and masking based blocking to a new layer-based system which uses BYONDs native layer handling to mask the emissive overlays.

292b217911 Layer overhaul (#57915)
## About The Pull Request
Changes up some layer and plane defines for no particular reason lol

## Why It's Good For The Game
Planes actually override layers, and layers control ordering within planes. A lot of the usage of plane and layer was wholly unnecessary. This refactor helps future maintainability while also being needed staging for _future features._

0f435d5dff Remove hideous inline tab indentation, and bans it in contributing guidelines (#56912)
Done using this command sed -Ei 's/(\s*\S+)\s*\t+/\1 /g' code/**/*.dm

We have countless examples in the codebase with this style gone wrong, and defines and such being on hideously different levels of indentation. Fixing this to keep the alignment involves tainting the blames of code your PR doesn't need to be touching at all. And ultimately, it's hideous.

There are some files that this sed makes uglier. I can fix these when they are pointed out, but I believe this is ultimately for the greater good of readability. I'm more concerned with if any strings relied on this.

Hi codeowners!

1f1b58bb26 Adds Neon Carpet (#55782)
* Adds emissive carpet, adds plane support to decal element

- Adds a basic abstract/debugging emissive carpet
- Makes decals capable of supporting plane
- Adds auto-smoothing decals

* Adds simple neon carpet variations

* Adds neon carpet reagents and recipes

* Refactors emissive blockers to allow multiple layers of emissive / emissive blocking objects

- Splits the emissive and emissive blocker plane masters into several plane masters which handle different layers of emissiveness.

* Makes neon carpet tile stacks emissive

* Rearranges and docs some emissive plane masters

- Folds the overlay lighting plane master into the emissive planes since it is also used to mask the lighting plane

* Fixes null mats_per_unit stack recombining after splitting

- I think I broke this a while ago when I reworked how stacks handle materials. Whoops.
- This basically only effects carpet at the moment. Good thing I did this when I did!

* Adds neon carpets to cargo

- Adds a cargo supply crate containing a _lot_ of neon carpets for 3000 credits

* Fixes neon carpet highlights leaking through vending machines and such

- Turns out vending machines axed their own emissive blockers whenever they updated their icon because they cleared their managed_vis_overlays...
- Generic emissive blocking has been elementized and some update_overlays procs have been straightened out.

* Fixes id_arg_index for the emissive blocker element

* Commits @Rohsie's suggestions

71314216f6 Tweaked insulated spray-on gloves (#56232)
Some tweaking and code smoothing of the spray-on gloves. The only
mechanical change is in also letting them be washed off (although it
takes a while under a shower or using a sink).

A visible message also provides better feedback.

* Make /wash a SHOULD_CALL_PARENT proc

A number of things depend on that signal being called.

* Makes suggested changes

- Adds SIGNAL_HANDLER to signal handler
- Changes name of turf variable for readability
- Reenables lighting object override of parent

Adds in a new type for the lighting system, the directional one. It piggybacks on the overlay lighting to create a directional effect + adds a nice visual cone mask to make the effect feel really directional.
Also: made the static light system respect the light_on variable.

It feels really nice to shine AT things you're looking at with flashlights and the such, it makes maintenance scouring much more immersive too.
Adds more paranoia as you dont see light behind yourself when you've got a flashlight. Plus makes ambushes more fun

eda7c6ca55 Overlay lighting component (#52413)
Sparks no longer lag, projectile beams move super smoothly, same with mobs and whatnot. This also allows for easy expansion into directional lights, field-of-view, wee-woo rotating lights or whatever.

It does have a downside: things right-clicked or checked through the alt+click tab will show the light overlay:


This is a BYOND limitation, very well worth it IMO.

🆑
add: Smooth movable lighting system implemented. Projectiles, sparks, thrown flashlights or moving mobs with lights should be much smoother and less laggy.
balance: Light sources no longer stack in range, though they still do in intensity.

25f670f8de Opacity refactor (#52881)
Moves all opacity var manipulation to a proc which sends a signal.
    light_blocker element for movable opaque atoms made, which tracks its movement and updates the affected turfs for proper lighting updates.
    has_opaque_atom boolean replaced by the opacity_sources lazylist to keep track of the sources, and a directional_opacity which serves a similar function but also allows for future expansion with on-border opaque objects (not yet implemented).
    Some opacity-related sight procs optimized as a result of this.
    Some variables moved to the object's definition.
    A define or two added into the mix for clarity.
    Some code cleaning, like turning booleans into their defines.
    One file renamed for clarity.

6ff08e1c69 Color standardization, vars moved, and signals (#52574)
Defined all the existing light_color values.
    Moved their definitions to colors.dm
    Made white the default color. It was so already, but that was very obscured.
    Moved the atom light-related variables to the atom definition.
    Wrapped changes to variables such as light_color into procs that report the event through signals.
    Moved the light_on variable to the atom level, also adding a signal for its changing, to represent toggling lights.
    Cleaned up a little bit of code in where new variables were defined before redefinitions.

This is all atomization to reduce changes in #52413
None of this affect gameplay at all, it's all code cleaning and refactoring.

There's more colors to standardize, a search for color = will find lots of targets, and I see little need to have both the LIGHT_COLOR and COLOR patterns, but I don't want to make this PR bigger than it already is.

0741b1977f Cleanable cleanup (#52477)
* Don't initialize the atom_colours list on atoms until it's actually needed

* Moved bloody_hands var to mob/living/carbon/human instead

* Added COMSIG_COMPONENT_CLEAN_RADIATION signal to reduce moms spaghetti

The shower and suit storage unit now calls this signal instead of either doing it manually or doing it via the washed proc

* Cleaned up carbon washing, renamed washed to wash

* The wash proc now doesn't take the washer as first arg because that wasn't used anywhere
* The wash strength is no longer optional
* Carbons now overrides the wash proc instead of using the signal
* Properly check for obscuredness before washing any equipped items
* Properly wash all items and bloody hands etc
* Added clean_lips proc for humans for cleaning any lipstick

* Cleaned up washing. Washy stuff now calls wash instead of calling the clean signal directly

* Renamed is_cleanable to ismopable, gives this category a more fitting purpose. Many things beyond floor decals are cleanable. It is now also determined using the atom layer instead to make it more generic.
* Properly utilize the is_cleanable define
* Added wash override for turfs where they also wash any mopables on the same tile
* Space cleaner and cleaning element etc now simply washes the mob instead of doing its own manual cleaning on ~some~ equipped items

* Non-component washables now simply override wash instead of registering for the clean signal

* Fixed some left over clean signal registers not returning true

* Added clean_strength var to space cleaner

* Moved human wash proc next to the other washing procs

* Also wash glasses and mask if not obscured when washing face

* Fixed attempting to "scoop up" cleanable decals using a rag

* Fixed plasmaman spacehelm icon not updating when washed

Also removed a duplicated worn_overlays proc

* Fixed head icon not updating when washing lipstick

* Moved radioactive clean signal register to where it should be

* Added atom radiate VV verb for debugging

* Redesigned the CLEAN constants into a more sensible flags setup

This makes it more dynamic, cleaning apparatuses can clean more specific than just a cleaning strength.

* CLEAN_TYPE_* flags indicate a specific cleanable, such as blood, fingerprints or disease
* CLEAN_* consts consist of a combination of cleaning types to make cleaning apparatuses have a consistent behaviour on what they clean

* Fixed broken rad removal logic in showers

* Apply suggestions from code review
