# Description
I've made it so that when a room is explosively depressurized(or when a
body of high pressure air flows into one of lower pressure air), that
entities inside are launched by the air pressure with effects according
to their mass. An entity's mass is now used as an innate resistance to
forced movement by airflow, and more massive entities are both less
likely to be launched, and will launch less far than others. While
lighter entities are launched far more easily, and will shoot off into
space quite quickly! Spacing departments has never been so exciting!
This can be made extraordinarily fun if more objects are given the
ability to injure people when colliding with them at high speeds.
As a note, Humans are very unlikely to be sucked into space at a typical
force generated from a 101kpa room venting into 0kpa, unless they
happened to be standing right next to the opening to space when it was
created. The same cannot be said for "Lighter-Than-Human" species such
as Felinids and Harpies. I guess that's just the price to pay for being
cute. :)
On a plus side, because the math behind this is simplified even further
than it was before, this actually runs more efficiently than the
previous system.
# TODO
Nothing, this is basically done. I've spent a good 6 hours straight
finely tuning the system until I was satisfied that it reflects
something close to reality.

- add: Atmospheric "Throws" are now calculated using object mass, and
behave accordingly. Tiny objects will shoot out of rooms quite fast!

<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).

> Below is a video showing that atmos still seems to work, and that
trimming of disconnected tiles works:
