# Description
Gas Tile Overlay had a non-functional check for preventing it from
running on every frame. This PR fixes the frametime stopper, such that
it actually prevents the system from constantly running at all times.
# Changelog
🆑
- tweak: Made some performance improvements to the Gas Tile Overlay.

<details open="true"><summary><h1>Original Body</h1></summary>
> This PR reworks how some parts of atmos code work. Originally it was
just meant to be a performance and bugfix PR, but it has ballooned in
scope. I'm not sure about some of my changes largely because I'm not
sure if some things were an oversight or an intentional decision for
some reason.
>
> List of changes:
> - The `MolesArchived float[]` field is now read-only
> - It simply gets zeroed whenever the `GasMixture` is set to null
instead of constantly reallocating
> - Airtight query information is now cached in `TileAtmosphere`
> - This means that it should only iterate over anchored entities once
per update.
> - Previously an invalidated atmos tile would cause
`ProcessRevalidate()` to query airtight entities on the same tile six
times by calling a combination of `GridIsTileAirBlocked()`,
`NeedsVacuumFixing()`, and `GridIsTileAirBlocked()`. So this should help
significantly reduce component lookups & entity enumeration.
> - This does change some behaviour. In particular blocked directions
are now only updated if the tile was invalidated prior to the current
atmos-update, and will only ever be updated once per atmos-update.
> - AFAIK this only has an effect if the invalid tile processing is
deferred over multiple ticks, and I don't think it should cause any
issues?
> - Fixes a potential bug, where tiles might not dispose of their
excited group if their direction flags changed.
> - `MapAtmosphereComponent.Mixture` is now always immutable and no
longer nullable
> - I'm not sure why the mixture was nullable before? AFAICT the
component is meaningless if its null?
> - Space "gas" was always immutable, but there was nothing that
required planet atmospheres to be immutable. Requiring that it be
immutable gets rid of the constant gas mixture cloning.
> - I don't know if there was a reason for why they weren't immutable to
begin with.
> - Fixes lungs removing too much air from a gas mixture, resulting in
negative moles.
> - `GasMixture.Moles` is now `[Access]` restricted to the atmosphere
system.
> - This is to prevent people from improperly modifying the gas mixtures
(e.g., lungs), or accidentally modifying immutable mixtures.
> - Fixes an issue where non-grid atmosphere tiles would fail to update
their adjacent tiles, resulting in null reference exception spam
> - Fixes#21732
> - Fixes#21210 (probably)
> - Disconnected atmosphere tiles, i.e., tiles that aren't on or
adjacent to a grid tile, will now get removed from the tile set.
Previously the tile set would just always increase, with tiles never
getting removed.
> - Removes various redundant component and tile-definition queries.
> - Removes some method events in favour of just using methods.
> - Map-exposded tiles now get updated when a map's atmosphere changes
(or the grid moves across maps).
> - Adds a `setmapatmos` command for adding map-wide atmospheres.
> - Fixed (non-planet) map atmospheres rendering over grids.
>
> ## Media
>
> This PR also includes changes to the atmos debug overlay, though I've
also split that off into a separate PR to make reviewing easier
(#22520).

trimming of disconnected tiles works:

* Use new Subs.CVar helper
Removes manual config OnValueChanged calls, removes need to remember to manually unsubscribe.
This both reduces boilerplate and fixes many issues where subscriptions weren't removed on entity system shutdown.
* Fix a bunch of warnings
* More warning fixes
* Use new DateTime serializer to get rid of ISerializationHooks in changelog code.
* Get rid of some more ISerializationHooks for enums
* And a little more
* Apply suggestions from code review

(cherry picked from commit 68ce53ae17985876d6d112b764b2144964a9f42e)
* Give .props files 2-space indents.
* Move to Central Package Management.
Allows us to store NuGet package versions all in one place. Yay!
* Update NuGet packages and fix code for changes.
Notable:
Changes to ILVerify.
Npgsql doesn't need hacks for inet anymore, now we need hacks to make the old code work with this new reality.
NUnit's analyzers are already complaining and I didn't even update it to 4.x yet.
TerraFX changed to GetLastSystemError so error handling had to be changed.
Buncha APIs have more NRT annotations.
* Remove dotnet-eng NuGet package source.
I genuinely don't know what this was for, and Central Package Management starts throwing warnings about it, so YEET.
* Remove Robust.Physics project.
Never used.
* Remove erroneous NVorbis reference.
Should be VorbisPizza and otherwise wasn't used.
* Sandbox fixes
* Remove unused unit test package references.
Castle.Core and NUnit.ConsoleRunner.
* Update NUnit to 4.0.1
This requires replacing all the old assertion methods because they removed them 🥲
* Oh so that's what dotnet-eng was used for. Yeah ok that makes sense.
* Add Robust.Analyzers.Test
* Update submodule
* commit to re-run CI
(cherry picked from commit a6c9c36b688a1ba78ff4c12502e81661cf607b6c)
* Refactors the entirety of the AtmosphereSystem public-facing API to allow for multiple atmos backends.
* actually compiles
* Remove commented out code
* funny bracket
* Move archived moles, temperature from GasMixture to TileAtmosphere.
* WIP customizable map default mixture
still VERY buggy
* broken mess
aaaaaaaaaaaaa
* Fix lattice, etc not being considered space
* visualization for "IsSpace"
* help
* Update Content.Client/Atmos/Overlays/AtmosDebugOverlay.cs
Co-authored-by: Moony <moonheart08@users.noreply.github.com>
* Holy SHIT it compiles AGAIN
* Fix AtmosDeviceSystem crash at shutdown
* Fix immutable tiles on map blueprints not being fixed by fixgridatmos/revalidate.
* Use space instead of gasmixture immutable for heat capacity calculations
* Remove all LINDA-specific code from GasMixture, move it to TileAtmosphere/AtmosphereSystem instead.
* Fix roundstart tiles not processing
* Update Content.Server/Atmos/Commands/SetTemperatureCommand.cs
Co-authored-by: metalgearsloth <31366439+metalgearsloth@users.noreply.github.com>
* Update Content.Server/Atmos/EntitySystems/AtmosphereSystem.API.cs
Changed Files tab is so large I can't commit both suggestions at once mfw
