c747cc526b Group stress test examples (#4289)
# Objective

- Several examples are useful for qualitative tests of Bevy's performance
- By contrast, these are less useful for learning material: they are often relatively complex and have large amounts of setup and are performance optimized.

## Solution

- Move bevymark, many_sprites and many_cubes into the new stress_tests example folder
- Move contributors into the games folder: unlike the remaining examples in the 2d folder, it is not focused on demonstrating a clear feature.

e8cd2fc727 Audio control at start of playback (#4110)
# Objective

- While playing with volume, I noticed that when setting the volume just after playback start, I still get a few milliseconds at normal volume

## Solution

- Replace `play_in_loop` with `play_with_settings` that allows from more controls
- Adds a `PlaybackSettings` to specify the settings from start. Can be used: `PlaybackSettings::LOOP.with_volume(0.75)`

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.

64d217823d Allow iter combinations on queries with filters (#3656)
# Objective

- Previously, `iter_combinations()` does not work on queries that have filters.
- Fixes #3651

## Solution

- Derived Copy on all `*Fetch<T>` structs, and manually implemented `Clone` to allow the test to pass (`.count()` does not work on `QueryCombinationIter` when `Clone` is derived)

01bdf67c33 Improve the set_active_camera system (#4251)
# Objective

- Make `set_active_camera` system correctly respond to camera deletion, while preserving its correct behavior on first ever frame and any consequent frame, and with multiple cameras of the same type available in the world.
- Fixes #4227

## Solution

- Add a check that the entity referred to by `ActiveCamera` still exists in the world.

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.

6f16580b8a Fix clicked UI nodes getting reset when hovering child nodes (#4194)
# Objective

Fixes #4193

## Solution

When resetting a node's `Interaction` to `None`, ignore any `Clicked` node because that should be handled by the mouse release check exclusively.

9d54f33974 Skinned extraction speedup (#4428)
# Objective

- While animating 501 https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/BrainStem, I noticed things were getting a little slow
- Looking in tracy, the system `extract_skinned_meshes` is taking a lot of time, with a mean duration of 15.17ms

## Solution

- ~~Use `Vec` instead of a `SmallVec`~~
- ~~Don't use an temporary variable~~
- Compute the affine matrix as an `Affine3A` instead
- Remove the `temp` vec

| |mean|
|---|---|
|base|15.17ms|
|~~vec~~|~~9.31ms~~|
|~~no temp variable~~|~~11.31ms~~|
|removing the temp vector|8.43ms|
|affine|13.21ms|

c5963b4fd5 Use storage buffers for clustered forward point lights (#3989)
# Objective

- Make use of storage buffers, where they are available, for clustered forward bindings to support far more point lights in a scene
- Fixes #3605 
- Based on top of #4079 

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

e7e74457c7 scene viewer improvements: animation reset (#4420)
# Objective

- Changing animation mid animation can leave the model not in its original position
- ~~The movement speed is fixed, no matter the size of the model~~

## Solution

- when changing animation, set it to its initial state and wait for one frame before changing the animation
- ~~when settings the camera controller, use the camera transform to know how far it is from the origin and use the distance for the speed~~

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`.

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`.

0ed08d6a15 fix multiple_windows example (#4389)
The example was broken in #3635 when the `ActiveCamera` logic was introduced, after which there could only be one active `Camera3d` globally.
Ideally there could be one `Camera3d` per render target, not globally, but that isn't the case yet.

To fix the example, we need to
- don't use `Camera3d` twice, add a new `SecondWindowCamera3d` marker
- add the `CameraTypePlugin::<SecondWindowCamera3d>`
- extract the correct `RenderPhase`s
- add a 3d pass driver node for the secondary camera

Fixes #4378

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.

648544faf1 Bump actions/cache from 2 to 3 (#4348)
Bumps [actions/cache](https://github.com/actions/cache) from 2 to 3.

<blockquote>
<h2>v3.0.0</h2>
<ul>
<li>
<p>This change adds a minimum runner version(node12 -&gt; node16), which can break users using an out-of-date/fork of the runner. This would be most commonly affecting users on GHES 3.3 or before, as those runners do not support node16 actions and they can use actions from github.com via <a href="https://docs.github.com/en/enterprise-server@3.0/admin/github-actions/managing-access-to-actions-from-githubcom/enabling-automatic-access-to-githubcom-actions-using-github-connect">github connect</a> or manually copying the repo to their GHES instance.</p>
</li>
<li>
<p>Few dependencies and cache action usage examples have also been updated.</p>
</li>
</ul>
<h2>v2.1.7</h2>
<p>Support 10GB cache upload using the latest version <code>1.0.8</code> of <a href="https://www.npmjs.com/package/@actions/cache"><code>@actions/cache</code> </a></p>
<h2>v2.1.6</h2>
<ul>
<li>Catch unhandled &quot;bad file descriptor&quot; errors that sometimes occurs when the cache server returns non-successful response (<a href="https://github-redirect.dependabot.com/actions/cache/pull/596">actions/cache#596</a>)</li>
</ul>
<h2>v2.1.5</h2>
<ul>
<li>Fix permissions error seen when extracting caches with GNU tar that were previously created using BSD tar (<a href="https://github-redirect.dependabot.com/actions/cache/issues/527">actions/cache#527</a>)</li>
</ul>
<h2>v2.1.4</h2>
<ul>
<li>Make caching more verbose <a href="https://github-redirect.dependabot.com/actions/toolkit/pull/650">#650</a></li>
<li>Use GNU tar on macOS if available <a href="https://github-redirect.dependabot.com/actions/toolkit/pull/701">#701</a></li>
</ul>
<h2>v2.1.3</h2>
<ul>
<li>Upgrades <code>@actions/core</code> to v1.2.6 for <a href="https://github.com/advisories/GHSA-mfwh-5m23-j46w">CVE-2020-15228</a>. This action was not using the affected methods.</li>
<li>Fix error handling in <code>uploadChunk</code> where 400-level errors were not being detected and handled correctly</li>
</ul>
<h2>v2.1.2</h2>
<ul>
<li>Adds input to limit the chunk upload size, useful for self-hosted runners with slower upload speeds</li>
<li>No-op when executing on GHES</li>
</ul>
<h2>v2.1.1</h2>
<ul>
<li>Update <code>@actions/cache</code> package to <code>v1.0.2</code> which allows cache action to use posix format when taring files.</li>
</ul>
<h2>v2.1.0</h2>
<ul>
<li>Replaces the <code>http-client</code> with the Azure Storage SDK for NodeJS when downloading cache content from Azure.  This should help improve download performance and reliability as the SDK downloads files in 4 MB chunks, which can be parallelized and retried independently</li>
<li>Display download progress and speed</li>

b33dae31ec Rename get_multiple APIs to get_many (#4384)
# Objective

-  std's new APIs do the same thing as `Query::get_multiple_mut`, but are called `get_many`: https://github.com/rust-lang/rust/pull/83608

## Solution

- Find and replace `get_multiple` with `get_many`

48ac955afd Fix loading non-TriangleList meshes without normals in gltf loader (#4376)
# Objective
Make it so that loading in a mesh without normals that is not a `TriangleList` succeeds.

## Solution
Flat normals can only be calculated on a mesh made of triangles.
Check whether the mesh is a `TriangleList` before trying to compute missing normals.

## Additional changes
The panic condition in `duplicate_vertices` did not make sense to me. I moved it to `compute_flat_normals` where the algorithm would produce incorrect results if the mesh is not a `TriangleList`.

aca7fc1854 Remove outdated perf comments (#4374)
# Objective

- The perf comments, added (by me) in https://github.com/bevyengine/bevy/pull/1349, became outdated once the initialisation call started to take an exclusive reference, (presumably in https://github.com/bevyengine/bevy/pull/1525).
- They have been naïvely transferred along ever since

## Solution

- Remove them

3af90b67a6 Update RemovedComponents doc comment (#4373)
# Objective

- Clarify `RemovedComponents` are flushed in `CoreStage::Last` and systems relying on that should run before that stage

## Solution

- Update `RemovedComponents` doc comment

4480b36bf3 Replace confusing links from CONTRIBUTING.md with short instruction (#4369)
# Objective
CONTRIBUTING.md contains links to pages that are restricted to Bevy Engine Org members.
First time contributors who read CONTRIBUTING.md will end up on a confusing 404 page if they try to follow the link.

Relevant discussion: #4365

## Solution

Replace links with directions to the Triage Team page.

### Note

I'm not sure if `assign themselves as a member` is accurate. I think that is what `automatically request membership` was referring to, but i can't check for myself 😉

637a149910 unsafeify World::entities_mut (#4093)
# Objective
make bevy ecs a lil bit less unsound

## Solution
make unsound API unsafe so that there is an unsafe block to blame:

```rust
use bevy_ecs::prelude::*;

#[derive(Debug, Component)]
struct Foo(u8);

fn main() {
    let mut world = World::new();
    let e1 = world.spawn().id();
    let e2 = world.spawn().insert(Foo(2)).id();
    world.entities_mut().meta[0] = world.entities_mut().meta[1].clone();
    let foo = world.entity(e1).get::<Foo>().unwrap();
    // whoo i love having components i dont have
    dbg!(foo);
}
```

This is not _strictly_ speaking UB, however: 
- `Query::get_multiple` cannot work if this is allowed
- bevy_ecs is a pile of unsafe code whose soundness generally depends on the world being in a "correct" state with "no funny business" so it seems best to disallow this
- it is trivial to get bevy to panic inside of functions with safety invariants that have been violated (the entity location is not valid)
- it seems to violate what the safety invariant on `Entities::flush` is trying to ensure

2b35dbabfd impl Reflect and Debug for Mesh2dHandle (#4368)
# Objective

An entity spawned with `MaterialMesh2dBundle<M>` cannot be saved and spawned using `DynamicScene` because the `Mesh2dHandle` component does not `impl Reflect`.  

## Solution

Add `#[derive(Reflect)]` and `#[reflect(Component)]` to `Mesh2dHandle`, and call `register_type` in `SpritePlugin`.  Also add `#[derive(Debug)]` since I'm touching the `derive`s anyway.
