3fbe3683d9 Improve debugging tools for change detection (#4160)
# Objective

1. Previously, the `change_tick` and `last_change_tick` fields on `SystemChangeTick` [were `pub`](https://docs.rs/bevy/0.6.1/bevy/ecs/system/struct.SystemChangeTick.html).
   1.  This was actively misleading, as while this can be fetched as a `SystemParam`, a copy is returned instead
2. This information could be useful for debugging, but there was no way to investigate when data was changed.
3. There were no docs!

## Solution

1. Move these to a getter method.
2. Add `last_changed` method to the `DetectChanges` trait to enable inspection of when data was last changed.
3. Add docs.

# Changelog

 `SystemChangeTick` now provides getter methods for the current and previous change tick, rather than public fields.
 This can be combined with `DetectChanges::last_changed()` to debug the timing of changes.

# Migration guide

The `change_tick` and `last_change_tick` fields on `SystemChangeTick` are now private, use the corresponding getter method instead.

b9f738da8d move system_param fetch struct into anonymous scope to avoid name collisions (#4100)
# Objective

avoid naming collisions with user structs when deriving ``system_param``.

## Solution

~rename the fetch struct created by ``#[derive(system_param)]`` from ``{}State`` to ``{}SysParamState``.~
place the fetch struct into an anonymous scope.

## Migration Guide

For code that was using a system param's fetch struct, such as ``EventReader``'s ``EventReaderState``, the fetch struct can now be identified via the SystemParam trait associated type ``Fetch``, e.g. for ``EventReader<T>`` it can be identified as ``<EventReader<'static, 'static, T> as SystemParam>::Fetch``

a011f4d53c Make Transform propagation correct in the presence of updated children (#4608)
Supercedes https://github.com/bevyengine/bevy/pull/3340, and absorbs the test from there.

# Objective

- Fixes #3329

## Solution

- If the `Children` component has changed, we currently do not have a way to know how it has changed.
- Therefore, we must update the hierarchy downwards  from that point to be correct.

4c194084b4 bevy_reflect: Add GetTypeRegistration impl for reflected tuples (#4226)
# Objective

Reflected tuples do not implement `GetTypeRegistration`, preventing us from registering our tuples, like:

```rust
app.register_type::<(i32, i32)>();
```

This is especially important for things like using #4042 to improve the scene format or implementing #4154 to recursively register fields.

## Solution

Added an implementation to the tuple macro:

```rust
impl<$($name: Reflect + for<'de> Deserialize<'de>),*> GetTypeRegistration for ($($name,)*) {
  fn get_type_registration() -> TypeRegistration {
    let mut registration = TypeRegistration::of::<($($name,)*)>();
    registration.insert::<ReflectDeserialize>(FromType::<($($name,)*)>::from_type());
    registration
  }
}
```

This requires that the tuple's types implement `Deserialize`. This is exactly how `Vec` and `HashMap` handle it:

```rust
impl<T: FromReflect + for<'de> Deserialize<'de>> GetTypeRegistration for Vec<T> {
  fn get_type_registration() -> TypeRegistration {
    let mut registration = TypeRegistration::of::<Vec<T>>();
    registration.insert::<ReflectDeserialize>(FromType::<Vec<T>>::from_type());
    registration
  }
}
```

e29bd50de8 Add file metadata to AssetIo (#2123)
This is a replacement for #2106

This adds a `Metadata` struct which contains metadata information about a file, at the moment only the file type.
It also adds a `get_metadata` to `AssetIo` trait and an `asset_io` accessor method to `AssetServer` and `LoadContext`

I am not sure about the changes in `AndroidAssetIo ` and `WasmAssetIo`.

8283db69b4 Remind users to initialize their systems before running them (#3947)
# Objective

- Manually running systems is a somewhat obscure process: systems must be initialized before they are run
- The unwrap is rather hard to debug.

## Solution

- Replace unwraps in `FunctionSystem` methods with expects (progress towards #3892).
- Briefly document this requirement.

51509a9a3e Change gamepad.rs tuples to normal structs (#4519)
# Objective

- Part of the splitting process of #3692.

## Solution

- Remove / change the tuple structs inside of `gamepad.rs` of `bevy_input` to normal structs.

## Reasons

- It made the `gamepad_connection_system` cleaner.
- It made the `gamepad_input_events.rs` example cleaner (which is probably the most notable change for the user facing API).
- Tuple structs are not descriptive (`.0`, `.1`).
- Using tuple structs for more than 1 field is a bad idea (This means that the `Gamepad` type might be fine as a tuple struct, but I still prefer normal structs over tuple structs).

Feel free to discuss this change as this is more or less just a matter of taste.

## Changelog

### Changed

- The `Gamepad`, `GamepadButton`, `GamepadAxis`, `GamepadEvent` and `GamepadEventRaw` types are now normal structs instead of tuple structs and have a `new()` function.

## Migration Guide

- The `Gamepad`, `GamepadButton`, `GamepadAxis`, `GamepadEvent` and `GamepadEventRaw` types are now normal structs instead of tuple structs and have a `new()` function. To migrate change every instantiation to use the `new()` function instead and use the appropriate field names instead of `.0` and `.1`.

e9db69af81 Tidy up PluginGroupBuilder by moving Plugin index retrieval to it's own function (#4446)
# Objective

- Clean up duplicate code in the add_before/add_after functions in PluginGroupBuilder.

## Solution

- moved index retrieval code to a private function index_of() for the PluginGroupBuilder.
- change is just tidying up. No real change to functionality.

2c145826a3 Fix type parameter name conflicts of derive(Bundle) (#4636)
# Objective

This code currently fails to compile with error ``the name `T` is already used for a generic parameter in this item's generic parameters``, because `T` is also used in code generated by `derive(Bundle)`.

```rust
#[derive(Bundle)]
struct MyBundle<T: Component> {
    component: T,
}
```

## Solution

Add double underscores to type parameter names in `derive(Bundle)`.

b9102b8836 Introduce tests for derive(WorldQuery) (#4625)
The only tests we had for `derive(WorldQuery)` checked that the derive doesnt panic/emit a `compiler_error!`. This PR adds tests that actually assert the returned values of a query using the derived `WorldQuery` impl. Also adds a compile fail test to check that we correctly error on read only world queries containing mutable world queries.

990d5c0879 Make AnimationClip::duration return value instead of reference (#4617)
Tiny follow-up to https://github.com/bevyengine/bevy/pull/4615 as discussed on Discord here: https://discord.com/channels/691052431525675048/692572690833473578/968945307767414855

Since f32 is `Copy` and smaller than a reference on most systems (or at least not larger), there's no reason not to copy it, which should be more convenient to use.

73c78c3667 Use lifetimed, type erased pointers in bevy_ecs (#3001)
# Objective

`bevy_ecs` has large amounts of unsafe code which is hard to get right and makes it difficult to audit for soundness.

## Solution

Introduce lifetimed, type-erased pointers: `Ptr<'a>` `PtrMut<'a>` `OwningPtr<'a>'` and `ThinSlicePtr<'a, T>` which are newtypes around a raw pointer with a lifetime and conceptually representing strong invariants about the pointee and validity of the pointer.

The process of converting bevy_ecs to use these has already caught multiple cases of unsound behavior.

## Changelog

TL;DR for release notes: `bevy_ecs` now uses lifetimed, type-erased pointers internally, significantly improving safety and legibility without sacrificing performance. This should have approximately no end user impact, unless you were meddling with the (unfortunately public) internals of `bevy_ecs`.

- `Fetch`, `FilterFetch` and `ReadOnlyFetch` trait no longer have a `'state` lifetime
    - this was unneeded
- `ReadOnly/Fetch` associated types on `WorldQuery` are now on a new `WorldQueryGats<'world>` trait
    - was required to work around lack of Generic Associated Types (we wish to express `type Fetch<'a>: Fetch<'a>`)
- `derive(WorldQuery)` no longer requires `'w` lifetime on struct
    - this was unneeded, and improves the end user experience
- `EntityMut::get_unchecked_mut` returns `&'_ mut T` not `&'w mut T`
    - allows easier use of unsafe API with less footguns, and can be worked around via lifetime transmutery as a user
- `Bundle::from_components` now takes a `ctx` parameter to pass to the `FnMut` closure
    - required because closure return types can't borrow from captures
- `Fetch::init` takes `&'world World`, `Fetch::set_archetype` takes `&'world Archetype` and `&'world Tables`, `Fetch::set_table` takes `&'world Table`
    - allows types implementing `Fetch` to store borrows into world
- `WorldQuery` trait now has a `shrink` fn to shorten the lifetime in `Fetch::<'a>::Item`
    - this works around lack of subtyping of assoc types, rust doesnt allow you to turn `<T as Fetch<'static>>::Item'` into `<T as Fetch<'a>>::Item'`
    - `QueryCombinationsIter` requires this
- Most types implementing `Fetch` now have a lifetime `'w`
    - allows the fetches to store borrows of world data instead of using raw pointers

## Migration guide

- `EntityMut::get_unchecked_mut` returns a more restricted lifetime, there is no general way to migrate this as it depends on your code
- `Bundle::from_components` implementations must pass the `ctx` arg to `func`
- `Bundle::from_components` callers have to use a fn arg instead of closure captures for borrowing from world
- Remove lifetime args on `derive(WorldQuery)` structs as it is nonsensical
- `<Q as WorldQuery>::ReadOnly/Fetch` should be changed to either `RO/QueryFetch<'world>` or `<Q as WorldQueryGats<'world>>::ReadOnly/Fetch`
- `<F as Fetch<'w, 's>>` should be changed to `<F as Fetch<'w>>`
- Change the fn sigs of `Fetch::init/set_archetype/set_table` to match respective trait fn sigs
- Implement the required `fn shrink` on any `WorldQuery` implementations
- Move assoc types `Fetch` and `ReadOnlyFetch` on `WorldQuery` impls to `WorldQueryGats` impls
- Pass an appropriate `'world` lifetime to whatever fetch struct you are for some reason using

### Type inference regression

in some cases rustc may give spurrious errors when attempting to infer the `F` parameter on a query/querystate this can be fixed by manually specifying the type, i.e. `QueryState:🆕:<_, ()>(world)`. The error is rather confusing:

```rust=
error[E0271]: type mismatch resolving `<() as Fetch<'_>>::Item == bool`
    --> crates/bevy_pbr/src/render/light.rs:1413:30
     |

     |                              ^^^^^^^^^^^^^^^ expected `bool`, found `()`
     |
     = note: required because of the requirements on the impl of `for<'x> FilterFetch<'x>` for `<() as WorldQueryGats<'x>>::Fetch`
note: required by a bound in `bevy_ecs::query::QueryState::<Q, F>::new`
    --> crates/bevy_ecs/src/query/state.rs:49:32

     |                                ^^^^^^^^^^^^^^^ required by this bound in `bevy_ecs::query::QueryState::<Q, F>::new`
```

ddce22b614 Decouple some dependencies (#3886)
# Objective

Reduce from scratch build time.

## Solution

Reduce the size of the critical path by removing dependencies between crates where not necessary. For `cargo check --no-default-features` this reduced build time from ~51s to ~45s. For some commits I am not completely sure if the tradeoff between build time reduction and convenience caused by the commit is acceptable. If not, I can drop them.

71a246ce9e Improve QueryIter size_hint hints (#4244)
## Objective

This fixes #1686.

`size_hint` can be useful even if a little niche. For example,
`collect::<Vec<_>>()` uses the `size_hint` of Iterator it collects from
to pre-allocate a memory slice large enough to not require re-allocating
when pushing all the elements of the iterator.

## Solution

To this effect I made the following changes:
* Add a `IS_ARCHETYPAL` associated constant to the `Fetch` trait,
  this constant tells us when it is safe to assume that the `Fetch`
  relies exclusively on archetypes to filter queried entities
* Add `IS_ARCHETYPAL` to all the implementations of `Fetch`
* Use that constant in `QueryIter::size_hint` to provide a more useful

## Migration guide

The new associated constant is an API breaking change. For the user,
if they implemented a custom `Fetch`, it means they have to add this
associated constant to their implementation. Either `true` if it doesn't limit
the number of entities returned in a query beyond that of archetypes, or
`false` for when it does.

3d4e0066f4 Move float_ord from bevy_core to bevy_utils (#4189)
# Objective

Reduce the catch-all grab-bag of functionality in bevy_core by moving FloatOrd to bevy_utils.

A step in addressing #2931 and splitting bevy_core into more specific locations.

## Solution

Move FloatOrd into bevy_utils. Fix the compile errors.

As a result, bevy_core_pipeline, bevy_pbr, bevy_sprite, bevy_text, and bevy_ui no longer depend on bevy_core (they were only using it for `FloatOrd` previously).

361686a09c bevy_reflect: Added PartialEq to reflected f32 & f64 (#4217)
# Objective

Comparing two reflected floating points would always fail:

```rust
let a: &dyn Reflect = &1.23_f32;
let b: &dyn Reflect = &1.23_f32;

// Panics:
assert!(a.reflect_partial_eq(b).unwrap_or_default());
```

The comparison returns `None` since `f32` (and `f64`) does not have a reflected `PartialEq` implementation.

## Solution

Include `PartialEq` in the `impl_reflect_value!` macro call for both `f32` and `f64`.

`Hash` is still excluded since neither implement `Hash`.

Also added equality tests for some of the common types from `std` (including `f32`).

3d36ec41dc re-enable #[derive(TypeUuid)] for generics (#4118)
Support for deriving `TypeUuid` for types with generics was initially added in https://github.com/bevyengine/bevy/pull/2044 but later reverted https://github.com/bevyengine/bevy/pull/2204 because it lead to `MyStruct<A>` and `MyStruct<B>` having the same type uuid.

This PR fixes this by generating code like
```rust
#[derive(TypeUuid)]
#[uuid = "69b09733-a21a-4dab-a444-d472986bd672"]
struct Type<T>(T);

impl<T: TypeUuid> TypeUuid for Type<T> {
  const TYPE_UUID: TypeUuid = generate_compound_uuid(Uuid::from_bytes([/* 69b0 uuid */]), T::TYPE_UUID);
}
```

where `generate_compound_uuid` will XOR the non-metadata bits of the two UUIDs.

3f423074bf Make paused timers update just_finished on tick (#4445)
# Objective
Make timers update `just_finished` on tick, even if paused.
Fixes #4436

## Solution
`just_finished()` returns `times_finished > 0`. So I:
 * Renamed `times_finished` to `times_finished_this_tick` to reduce confusion.
 * Set `times_finished_this_tick` to `0` on tick when paused.
 * Additionally set `finished` to `false` if the timer is repeating.

Notably this change broke none of the existing tests, so I added a couple for this.

Files changed shows a lot of noise because of the rename. Check the first commit for the relevant changes.

# Objective

- Closes #335.
- Related #4285.
- Part of the splitting process of #3503.

## Solution

- Move `Rect` to `bevy_ui` and rename it to `UiRect`.

## Reasons

- `Rect` is only used in `bevy_ui` and therefore calling it `UiRect` makes the intent clearer.
- We have two types that are called `Rect` currently and it's missleading (see `bevy_sprite::Rect` and #335).
- Discussion in #3503.

## Changelog

### Changed

- The `Rect` type got moved from `bevy_math` to `bevy_ui` and renamed to `UiRect`.

## Migration Guide

- The `Rect` type got renamed to `UiRect`. To migrate you just have to change every occurrence of `Rect` to `UiRect`.

5047e1f08e bevy_reflect: Add as_reflect and as_reflect_mut (#4350)
# Objective

Trait objects that have `Reflect` as a supertrait cannot be upcast to a `dyn Reflect`.

Attempting something like:

```rust
trait MyTrait: Reflect {
  // ...
}

fn foo(value: &dyn MyTrait) {
  let reflected = value as &dyn Reflect; // Error!
  // ...
}
```

Results in `error[E0658]: trait upcasting coercion is experimental`.

The reason this is important is that a lot of `bevy_reflect` methods require a `&dyn Reflect`. This is trivial with concrete types, but if we don't know the concrete type (we only have the trait object), we can't use these methods. For example, we couldn't create a `ReflectSerializer` for the type since it expects a `&dyn Reflect` value— even though we should be able to.

## Solution

Add `as_reflect` and `as_reflect_mut` to `Reflect` to allow upcasting to a `dyn Reflect`:

```rust
trait MyTrait: Reflect {
  // ...
}

fn foo(value: &dyn MyTrait) {
  let reflected = value.as_reflect();
  // ...
}
```

## Alternatives

We could defer this type of logic to the crate/user. They can add these methods to their trait in the same exact way we do here. The main benefit of doing it ourselves is it makes things convenient for them (especially when using the derive macro).

We could also create an `AsReflect` trait with a blanket impl over all reflected types, however, I could not get that to work for trait objects since they aren't sized.

---

## Changelog

- Added trait method `Reflect::as_reflect(&self)`
- Added trait method `Reflect::as_reflect_mut(&mut self)`

## Migration Guide

- Manual implementors of `Reflect` will need to add implementations for the methods above (this should be pretty easy as most cases just need to return `self`)

7a7f097485 Move Size to bevy_ui (#4285)
# Objective

- Related #4276.
- Part of the splitting process of #3503.

## Solution

- Move `Size` to `bevy_ui`.

## Reasons

- `Size` is only needed in `bevy_ui` (because it needs to use `Val` instead of `f32`), but it's also used as a worse `Vec2`  replacement in other areas.
- `Vec2` is more powerful than `Size` so it should be used whenever possible.
- Discussion in #3503.

## Changelog

### Changed

- The `Size` type got moved from `bevy_math` to `bevy_ui`.

## Migration Guide

- The `Size` type got moved from `bevy::math` to `bevy::ui`. To migrate you just have to import `bevy::ui::Size` instead of `bevy::math::Math` or use the `bevy::prelude` instead.

0850975192 Add the possibility to create custom 2d orthographic cameras (#4048)
# Objective

- The `OrthographicCameraBundle` constructor for 2d cameras uses a hardcoded value for Z position and scale of the camera. It could be useful to be able to customize these values.

## Solution

- Add a new constructor `custom_2d` that takes `far` (Z position) and `scale` as parameters. The default constructor `new_2d` uses this constructor with `far = 1000.0` and `scale = 1.0`.

2a5202637f bevy_utils: remove hardcoded log level limit (#4580)
# Objective

- Debug logs are useful in release builds, but `tracing` logs are hard-capped (`release_max_level_info`) at the `info` level by `bevy_utils`.

## Solution

- This PR simply removes the limit in `bevy_utils` with no further actions.
- If any out-of-the box performance regressions arise, the steps to enable this `tracing` feature should be documented in a user guide in the future.

This PR closes #4069 and closes #1206.

## Alternatives considered

- Instruct the user to build with `debug-assertions` enabled: this is just a workaround, as it obviously enables all `debug-assertions` that affect more than logging itself.
- Re-exporting the feature from `tracing` and enabling it by default: I believe it just adds complexity and confusion, the `tracing` feature can also be re-enabled with one line in userland.

---

## Changelog

### Fixed

- Log level is not hard capped at `info` for release builds anymore.

## Migration Guide

- Maximum log levels for release builds is not enforced by Bevy anymore, to omit "debug" and "trace" level logs entirely from release builds, `tracing` must be added as a dependency with its `release_max_level_info` feature enabled in `Cargo.toml`. (`tracing = { version = "0.1", features = ["release_max_level_info"] }`)

93cee3b3c9 Make Time::update_with_instant public for use in tests (#4469)
# Objective

To test systems that implement frame rate-independent update logic, one needs to be able to mock `Time`. By mocking time, it's possible to write tests that confirm systems are frame rate-independent.

This is a follow-up PR to #2549 by @ostwilkens and based on his work.

## Solution

To mock `Time`, one needs to be able to manually update the Time resource with an `Instant` defined by the developer. This can be achieved by making the existing `Time::update_with_instant` method public for use in tests. 

## Changelog

- Make `Time::update_with_instant` public
- Add doc to `Time::update_with_instant` clarifying that the method should not be called outside of tests.
- Add doc test to `Time` demonstrating how to use `update_with_instant` in tests.

00c6acc0cc Rename ElementState to ButtonState (#4314)
# Objective

- Part of the splitting process of #3692.

## Solution

- Rename `ElementState` to `ButtonState`

## Reasons

- The old name was too generic.
- If something can be pressed it is automatically button-like (thanks to @alice-i-cecile for bringing it up in #3692).
- The reason it is called `ElementState` is because that's how `winit` calls it.
- It is used to define if a keyboard or mouse **button** is pressed or not.
- Discussion in #3692.

## Changelog

### Changed

- The `ElementState` type received a rename and is now called `ButtonState`.

## Migration Guide

- The `ElementState` type received a rename and is now called `ButtonState`. To migrate you just have to change every occurrence of `ElementState` to `ButtonState`.

46acb7753c SystemSet::before and after: take AsSystemLabel (#4503)
# Objective

`AsSystemLabel` has been introduced on system descriptors to make ordering systems more convenient, but `SystemSet::before` and `SystemSet::after` still take `SystemLabels` directly:

    use bevy::ecs::system::AsSystemLabel;

is currently necessary instead of

    /*…*/ SystemSet::new().before(foo) /*…*/

639fec20d6 Remove .system() (#4499)
Free at last!

# Objective

- Using `.system()` is no longer needed anywhere, and anyone using it will have already gotten a deprecation warning.
- https://github.com/bevyengine/bevy/pull/3302 was a super special case for `.system()`, since it was so prevelant. However, that's no reason.
- Despite it being deprecated, another couple of uses of it have already landed, including in the deprecating PR.
   - These have all been because of doc examples having warnings not breaking CI - 🎟️?

## Solution

- Remove it.
- It's gone

---

## Changelog

- You can no longer use `.system()`

## Migration Guide

- You can no longer use `.system()`. It was deprecated in 0.7.0, and you should have followed the deprecation warning then. You can just remove the method call.

- Built on top of #3989
- Improve performance of `assign_lights_to_clusters`

## Solution

- Remove the OBB-based cluster light assignment algorithm and calculation of view space AABBs
- Implement the 'iterative sphere refinement' algorithm used in Just Cause 3 by Emil Persson as documented in the Siggraph 2015 Practical Clustered Shading talk by Persson, on pages 42-44 http://newq.net/dl/pub/s2015_practical.pdf

193e8c4ada scene_viewer: load cameras (#4425)
# Objective

glTF files can contain cameras. Currently the scene viewer example uses _a_ camera defined in the file if possible, otherwise it spawns a new one. It would be nice if instead it could load all the cameras and cycle through them, while also having a separate user-controller camera.

## Solution

- instead of just a camera that is already defined, always spawn a new separate user-controller camera
- maintain a list of loaded cameras and cycle through them (wrapping to the user-controller camera) when pressing `C`

This matches the behavious that https://github.khronos.org/glTF-Sample-Viewer-Release/ has.

## Implementation notes

- The gltf scene asset loader just spawns the cameras into the world, but does not return a mapping of camera index to bevy entity. So instead the scene_viewer example just collects all spawned cameras with a good old `query.iter().collect()`, so the order is unspecified and may change between runs.

## Demo

https://user-images.githubusercontent.com/22177966/161826637-40161482-5b3b-4df5-aae8-1d5e9b918393.mp4

c12ee81822 bevy_app: add tracing event with tracy.frame_mark (#4320)
Currently `tracy` interprets the entire trace as one frame because the marker for frames isn't being recorded.

~~When an event with `tracy.trace_marker=true` is recorded, `tracing-tracy` will mark the frame as finished:
<aa0b96b2ae/tracing-tracy/src/lib.rs (L240)>~~

~~Unfortunately this leads to~~
```rs
INFO bevy_app:frame: bevy_app::app: finished frame tracy.frame_mark=true
```
~~being printed every frame (we can't use DEBUG because bevy_log sets `max_release_level_info`.~~

Instead of emitting an event that gets logged every frame, we can depend on tracy-client itself and call `finish_continuous_frame!();`

3756181e23 Change scaling mode to FixedHorizontal (#4055)
# Objective

- Fixes the issue with orthographic camera imported from glTF not displaying anything (mentioned in #4005).

## Solution

- This was due to wrong scaling mode being used. This PR simply changes WindowSize scaling mode to FixedHorizontal.

## Important Note

Currently, othographic scale in Blender, three.js, and possibly other software does not translate to Bevy (via glTF) because their developers have [misinterpreted the spec](https://github.com/KhronosGroup/glTF/issues/1663#issuecomment-618194015). The camera parameters have been clarified in glTF 2.0, which was released on October of 2021. In Blender 3.0.1 this issue has **not** been fixed yet. If you are importing orthographic cameras from Blender, you have to divide the scale by 2.

d478723e19 insert the gltf mesh name on the entity if there is one (#4119)
# Objective

- In glTF, mesh can be named. This named is used to be able to reference the mesh, but not as a component on the entity
- Bevy only added the node name to the parent node.


## Solution

- Also adds the name on the mesh entity if there is one.

Limitation: In glTF, it's possible to have one mesh (which can be named) corresponding to several primitives (which can't, but are the actual mesh). I added the mesh name to the entity with the `PbrBundle` matching the primitives, which means that a mesh with several primitives would all have the same name. I think this is acceptable...

b1afe2dcca Make System responsible for updating its own archetypes (#4115)
# Objective

- Make it possible to use `System`s outside of the scheduler/executor without having to define logic to track new archetypes and call `System::add_archetype()` for each.

## Solution

- Replace `System::add_archetype(&Archetype)` with `System::update_archetypes(&World)`, making systems responsible for tracking their own most recent archetype generation the way that `SystemState` already does.

This has minimal (or simplifying) effect on most of the code with the exception of `FunctionSystem`, which must now track the latest `ArchetypeGeneration` it saw instead of relying on the executor to do it.

This branch on an M1 Max can keep 60fps with about 2150 point lights of radius 1m in the Sponza scene where I've been testing. The bottleneck is mostly assigning lights to clusters which grows faster than linearly (I think 1000 lights was about 1.5ms and 5000 was 7.5ms). I have seen papers and presentations leveraging compute shaders that can get this up to over 1 million. That said, I think any further optimisations should probably be done in a separate PR.

## Solution

- Add `RenderDevice` to the `Material` and `SpecializedMaterial` trait `::key()` functions to allow setting flags on the keys depending on feature/limit availability
- Make `GpuPointLights` and `ViewClusterBuffers` into enums containing `UniformVec` and `StorageBuffer` variants. Implement the necessary API on them to make usage the same for both cases, and the only difference is at initialisation time.
- Appropriate shader defs in the shader code to handle the two cases

## Context on some decisions / open questions

- I'm using `max_storage_buffers_per_shader_stage >= 3` as a check to see if storage buffers are supported. I was thinking about diving into 'binding resource management' but it feels like we don't have enough use cases to understand the problem yet, and it is mostly a separate concern to this PR, so I think it should be handled separately.
- Should `ViewClusterBuffers` and `ViewClusterBindings` be merged, duplicating the count variables into the enum variants?

579928e8e0 bevy_pbr: Support flipping tangent space normal map y for DirectX normal maps (#4433)
# Objective

- Normal maps authored for DirectX use a left-handed convention and have their tangent space normal in the texture inverted from what we need. Support this.
- Details here: https://doc.babylonjs.com/divingDeeper/materials/advanced/normalMaps

## Solution

- Add a `StandardMaterial` `flip_normal_map_y` boolean field
- Add a `STANDARDMATERIAL_FLIP_NORMAL_MAP_Y` flag to `StandardMaterialFlags` and in the PBR shader
- Flip the y-component of the tangent space normal just after sampling it from the normal map texture

73edb11db6 Add more FromWorld implementations (#3945)
# Objective

Make `FromWorld` more useful for abstractions with a form similar to
```rs
trait FancyAbstraction {
  type PreInitializedData: FromWorld;
}
```

## Solution

Add a `FromWorld` implementation for `SystemState` as well as a way to group together multiple `FromWorld` implementing types as one.

Note: I plan to follow up this PR with another to add `Local` support to exclusive systems, which should get a fair amount of use from the `FromWorld` implementation on `SystemState`.

cf831d5185 input clear should not clear pressed (#4418)
# Objective

- Revert #4410 
- `Input<T>.clear()` is the method call at the end of each frame for inputs. Clearing `pressed` in it mean that checking if a key is pressed will always return false

# Objective

- Fixes https://github.com/bevyengine/bevy/issues/2096

## Solution

- This PR enables the drag-and-drop feature for winit on windows again, as the collision issue between cpal and winit has been fixed in https://github.com/RustAudio/cpal/pull/597. I confirmed the drag and drop example working on windows 10 with this change.
- ~~It also bumps the rodio version, though this is not strictly necessary.~~

5e70ad96c6 animations: don't ignore curves with one keyframe (#4406)
# Objective

- While playing with animated models, I noticed some were a little off

## Solution

- Some animations curves only have one keyframe, they are used to set a transform to a given value
- Those were ignored as we're never exactly at the ts 0.0 of an animation. going there explicitly (`.set_elapsed(0.0).pause()`) would crash
- Special case this as there isn't much to animate in this case

f90da74e32 Remove face_toward.rs (#4277)
# Objective

- Part of the splitting process of #3503.

## Solution

- Remove the `face_toward.rs` file containing the `FaceToward` trait.

## Reasons

- It is unused inside of `bevy`.
- The method `Mat4::face_toward` of the trait is identical to `Mat4::look_at_rh` (see https://docs.rs/glam/latest/glam/f32/struct.Mat4.html#method.look_at_rh).
- Discussion in #3503.

## Changelog

### Removed

- The `FaceToward` trait got removed.

## Migration Guide

-  The `FaceToward` trait got removed. To migrate you just have to change every occurrence of `Mat4::face_toward` to `Mat4::look_at_rh`.

c26be39719 Remove unnecessary system labels (#4340)
# Objective

- Since #4224, using labels which only refer to one system doesn't make sense.

## Solution

- Remove some of those.

## Future work

- We should remove the ability to use strings as system labels entirely. I haven't in this PR because there are tests which use this, and that's a lot of code to change.
   - The only use cases for labels are either intra-crate, which use #4224, or inter-crate, which should either use #4224 or explicit types. Neither of those should use strings.
