Properly handle repeated window close requests (#14573)
# Objective

Spamming the window close button on window may trigger a panic.

```
thread 'main' panicked at <Bevy repo>\crates\bevy_ecs\src\system\commands\mod.rs:1320:13:
error[B0003]: Could not insert a bundle (of type `bevy_window:🪟:ClosingWindow`) for entity 0v1#4294967296 because it doesn't exist in this World. See: https://bevyengine.org/learn/errors/b0003
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Encountered a panic when applying buffers for system `bevy_window::system::close_when_requested`!
2024-08-01T15:00:29.742612Z  WARN bevy_ecs::world::command_queue: CommandQueue has un-applied commands being dropped. Did you forget to call SystemState::apply?
Encountered a panic in system `bevy_app::main_schedule::Main::run_main`!
error: process didn't exit successfully: `target\debug\bevy.exe` (exit code: 101)
```

## Solution

Don't panic when trying to insert the `ClosingWindow` component into a
entity.

## Testing

Found and tested on windows. I haven't checked if this bug happens on
linux or macos.
For testing I ran this code:

```rust
use std::{thread, time::Duration};

use bevy::prelude::*;

fn lag() {
    thread::sleep(Duration::from_millis(300));
}

fn main() -> AppExit {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_systems(Update, lag)
        .run()
}
```

Then spammed the window close button. The panic no longer occurs.

B0003: Print caller (#14556)
# Objective

B0003 indicates that you tried to act upon a nonexistant entity, but
does not mention where the error occured:
```
2024-07-31T15:46:25.954840Z  WARN bevy_ecs::world: error[B0003]: Could not despawn entity Entity { index: 4294967295, generation: 1 } because it doesn't exist in this World. See: https://bevyengine.org/learn/errors/b0003
```

## Solution

Include caller location:

```
2024-07-31T15:46:25.954840Z  WARN bevy_ecs::world: error[B0003]: src/main.rs:18:11: Could not despawn entity Entity { index: 4294967295, generation: 1 } because it doesn't exist in this World. See: https://bevyengine.org/learn/errors/b0003
```

Open question: What should the exact message format be?

## Testing

None, this doesn't change any logic.

remove changelog file (#14564)
# Objective

- Remove CHANGELOG.md
- it's redundant with the release blog / the git log
- it's an extra step that may be forgotten in the release process (it
was not updated for the 0.14)
- it's an extra file at the root

## Solution

- Remove it

Add example showing how to use SpecializedMeshPipeline (#14370)
# Objective

- A lot of mid-level rendering apis are hard to figure out because they
don't have any examples
- SpecializedMeshPipeline can be really useful in some cases when you
want more flexibility than a Material without having to go to low level
apis.

## Solution

- Add an example showing how to make a custom `SpecializedMeshPipeline`.

## Testing

- Did you test these changes? If so, how?
- Are there any parts that need more testing?
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?

---

## Showcase

The examples just spawns 3 triangles in a triangle pattern.

Make AnimationPlayer::start and ::play work accordingly to documentation (#14546)
# Objective

While scrolling through the animation crate, I was confused by the docs
and code for the two methods. One does nothing for resetting an
animation, the other just resets the weights for whatever reason.

## Solution

Made the functions work accordingly to their documentation.
`start` now replays the animation.
And `play` doesn't reset the weight anymore. I have no clue why it
should. `play` is there to don't do anything to an already existing
animation.

## Testing

I tested the current 0.14 code with bevy playground in the Animated Fox
exampled and changed it such that on pressing space, either `play` or
`start` would be called. Neither changed anything.
I then inlined the function for start there and it restarted the
animation, so it should work.

---

## Migration Guide

`AnimationPlayer::start` now correspondingly to its docs restarts a
running animation.
`AnimationPlayer::play` doesn't reset the weight anymore.

time_system is ambiguous_with event_update_system (#14544)
# Objective

Resolve possible ambiguity detection panic between `time_system` and
`event_update_system`.

Fixes #14524

## Solution

Sets `.ambiguous_with(event_update_system)` on `time_system`. This is
slightly new territory for me, so please treat with scepticism.

## Testing

As described in the issue, added
```
        .configure_schedules(ScheduleBuildSettings {
            ambiguity_detection: LogLevel::Error,
            ..default()
        })
```
to the `time` example and ran it.

Fix Entity Debug Format (#14539)
# Objective

Fixes #12139

## Solution

See this comment on original issue for my proposal:
https://github.com/bevyengine/bevy/issues/12139#issuecomment-2241915791

This PR is an implementation of this proposal.

I modified the implementation of `fmt::Debug` to instead display
`0v0#12345` to ensure entity index, generation, and raw bits are all
present in the output for debug purposes while still keeping log message
concise.

`fmt::Display` remains as is (`0v0`) to offer an even shorter output.

To me, this is the most non-intrusive fix for this issue.

## Testing

Add `fn entity_debug` test

Fix rust beta lints (#14537)
# Objective

- Fixes #14517.

## Solution

- Replace two instances of `map()` with `inspect()`.
- `#[allow(dead_code)]` on `Bundle` derive macro tests.

## Testing

You need to install the beta toolchain, since these lints are not stable
yet.

Change SceneInstanceReady to trigger an observer. (#13859)
# Objective

The `SceneInstanceReady` event would be more ergonomic (and potentially
efficient) if it could be delivered to listeners attached to the scene
entities becoming ready rather than into a World-global queue.

This is an evolution of @Shatur's work in #9313.

## Solution

The scene spawner is changed to trigger observers on the scene entity
when it is ready rather than enqueue an event with `EventWriter`.

This addresses the two outstanding feature requests mentioned on #2218,
that i) the events should be "scoped" in some way and ii) that the
`InstanceId` should be included in the event.

## Testing

Modified the `scene_spawner::tests::event` test to use the new
mechanism.

---

## Changelog

- Changed `SceneInstanceReady` to trigger an entity observer rather than
be written to an event queue.
- Changed `SceneInstanceReady` to carry the `InstanceId` of the scene.

## Migration Guide

If you have a system which read `SceneInstanceReady` events:

> ```fn ready_system(ready_events: EventReader<'_, '_,
SceneInstanceReady>) {```

It must be rewritten as an observer:

> ```commands.observe(|trigger: Trigger<SceneInstanceReady>| {```

Or, if you were expecting the event in relation to a specific entity or
entities, as an entity observer:

> ```commands.entity(entity).observe(|trigger:
Trigger<SceneInstanceReady>| {```

Remove deprecated bevy_dynamic_plugin (#14534)
# Objective

- Dynamic plugins were deprecated in #13080 due to being unsound. The
plan was to deprecate them in 0.14 and remove them in 0.15.

## Solution

- Remove all dynamic plugin functionality.
- Update documentation to reflect this change.

---

## Migration Guide

Dynamic plugins were deprecated in 0.14 for being unsound, and they have
now been fully removed. Please consider using the alternatives listed in
the `bevy_dynamic_plugin` crate documentation, or worst-case scenario
you may copy the code from 0.14.

Track source location in change detection (#14034)
# Objective

- Make it possible to know *what* changed your component or resource.
- Common need when debugging, when you want to know the last code
location that mutated a value in the ECS.
- This feature would be very useful for the editor alongside system
stepping.

## Solution

- Adds the caller location to column data.
- Mutations now `track_caller` all the way up to the public API.
- Commands that invoke these functions immediately call
`Location::caller`, and pass this into the functions, instead of the
functions themselves attempting to get the caller. This would not work
for commands which are deferred, as the commands are executed by the
scheduler, not the user's code.

## Testing

- The `component_change_detection` example now shows where the component
was mutated:

```
2024-07-28T06:57:48.946022Z  INFO component_change_detection: Entity { index: 1, generation: 1 }: New value: MyComponent(0.0)
2024-07-28T06:57:49.004371Z  INFO component_change_detection: Entity { index: 1, generation: 1 }: New value: MyComponent(1.0)
2024-07-28T06:57:49.012738Z  WARN component_change_detection: Change detected!
        -> value: Ref(MyComponent(1.0))
        -> added: false
        -> changed: true
        -> changed by: examples/ecs/component_change_detection.rs:36:23
```

- It's also possible to inspect change location from a debugger:
<img width="608" alt="image"
src="https://github.com/user-attachments/assets/c90ecc7a-0462-457a-80ae-42e7f5d346b4">


---

## Changelog

- Added source locations to ECS change detection behind the
`track_change_detection` flag.

## Migration Guide

- Added `changed_by` field to many internal ECS functions used with
change detection when the `track_change_detection` feature flag is
enabled. Use Location::caller() to provide the source of the function
call.

Optimize cloning for Access-related structs (#14502)
# Objective

Optimize the cloning process for Access-related structs in the ECS
system, specifically targeting the `clone_from` method.

Previously, profiling showed that 1% of CPU time was spent in
`FixedBitSet`'s `drop_in_place`, due to the default `clone_from`
implementation:

```rust
fn clone_from(&mut self, source: &Self) {
    *self = source.clone()
}
```

This implementation causes unnecessary allocations and deallocations.
However, [FixedBitSet provides a more optimized clone_from
method](https://github.com/petgraph/fixedbitset/blob/master/src/lib.rs#L1445-L1465)
that avoids these allocations and utilizes SIMD instructions for better
performance.

This PR aims to leverage the optimized clone_from method of FixedBitSet
and implement custom clone_from methods for Access-related structs to
take full advantage of this optimization. By doing so, we expect to
significantly reduce CPU time spent on cloning operations and improve
overall system performance.



![image](https://github.com/user-attachments/assets/7526a5c5-c75b-4a9a-b8d2-891f64fd553b)


## Solution

- Implemented custom `clone` and `clone_from` methods for `Access`,
`FilteredAccess`, `AccessFilters`, and `FilteredAccessSet` structs.
- Removed `#[derive(Clone)]` and manually implemented `Clone` trait to
use optimized `clone_from` method from `FixedBitSet`.
- Added unit tests for cloning and `clone_from` methods to ensure
correctness.

## Testing

- Conducted performance testing comparing the original and optimized
versions.
- Measured CPU time consumption for the `clone_from` method:
  - Original version: 1.34% of CPU time
  - Optimized version: 0.338% of CPU time
- Compared FPS before and after the changes (results may vary depending
on the run):

Before optimization:

Stop website examples from linking to old URL with multiple redirects (#14500)
# Objective

Fixes https://github.com/bevyengine/bevy-website/issues/1558
Followup to #12348 

For the website pages extra link, it needs kebab case for the category
name and a trailing forward slash to make the link for the Bevy website
correct and not have unnecessary redirections.

## Solution

Changes the category name to kebab case for the extra link, and adds a
trailing forward slash to the link.

## Testing

I have tested these changes.

Clone my fork with the changes in `bevy-website/generate-wasm-examples/`
then `cd bevy && git switch bevy-website/1558_fix_beautify_example_links
&& cd ..` and then `./generate_wasm_examples.sh` to generate examples.

Afterwards runs `zola serve` and go to `http://127.0.0.1:1111/examples`
and hover over or inspect the cards links / anchors to see that the link
is now correct, click on any of the cards to see that there is no
redirects.

fix issue with phantom ui node children (#14490)
# Objective

The `ui_layout_system` relies on change detection to sync parent-child
relation to taffy. The children need to by synced before node removal to
avoid trying to set deleted nodes as children (due to how the different
queries collect entities). This however may leave nodes that were
removed set as children to other nodes in special cases.

Fixes #11385

## Solution

The solution is simply to re-sync the changed children after the nodes
are removed.

## Testing

Tested with `sickle_ui` where docking zone highlights would end up
glitched when docking was done in a certain manner:
- run the `docking_zone_splits` example
- pop out a tab from the top
- dock the floating panel in the center right
- grab another tab and try to hover the original static docking zone:
the highlight is semi-stuck
- (NOTE: sometimes it worked even without the fix due to scheduling
order not producing the bugged query results)

After the fix, the issue is no longer present.

NOTE: The performance impact should be minimal, as the child sync relies
on change detection. The change detection was also the reason the parent
nodes remained "stuck" with the phantom children if no other update were
done to them.

Refactor Bounded2d/Bounded3d to use isometries (#14485)
# Objective

Previously, this area of bevy_math used raw translation and rotations to
encode isometries, which did not exist earlier. The goal of this PR is
to make the codebase of bevy_math more harmonious by using actual
isometries (`Isometry2d`/`Isometry3d`) in these places instead — this
will hopefully make the interfaces more digestible for end-users, in
addition to facilitating conversions.

For instance, together with the addition of #14478, this means that a
bounding box for a collider with an isometric `Transform` can be
computed as
```rust
collider.aabb_3d(collider_transform.to_isometry())
```
instead of using manual destructuring. 

## Solution

- The traits `Bounded2d` and `Bounded3d` now use `Isometry2d` and
`Isometry3d` (respectively) instead of `translation` and `rotation`
parameters; e.g.:
  ```rust
  /// A trait with methods that return 3D bounding volumes for a shape.
  pub trait Bounded3d {
/// Get an axis-aligned bounding box for the shape translated and
rotated by the given isometry.
      fn aabb_3d(&self, isometry: Isometry3d) -> Aabb3d;
/// Get a bounding sphere for the shape translated and rotated by the
given isometry.
      fn bounding_sphere(&self, isometry: Isometry3d) -> BoundingSphere;
  }
  ```
- Similarly, the `from_point_cloud` constructors for axis-aligned
bounding boxes and bounding circles/spheres now take isometries instead
of separate `translation` and `rotation`; e.g.:
  ```rust
/// Computes the smallest [`Aabb3d`] containing the given set of points,
/// transformed by the rotation and translation of the given isometry.
    ///
    /// # Panics
    ///
    /// Panics if the given set of points is empty.
    #[inline(always)]
    pub fn from_point_cloud(
        isometry: Isometry3d,
        points: impl Iterator<Item = impl Into<Vec3A>>,
    ) -> Aabb3d { //... }
  ```

This has a couple additional results:
1. The end-user no longer interacts directly with `Into<Vec3A>` or
`Into<Rot2>` parameters; these conversions all happen earlier now,
inside the isometry types.
2. Similarly, almost all intermediate `Vec3 -> Vec3A` conversions have
been eliminated from the `Bounded3d` implementations for primitives.
This probably has some performance benefit, but I have not measured it
as of now.

## Testing

Existing unit tests help ensure that nothing has been broken in the
refactor.

---

## Migration Guide

The `Bounded2d` and `Bounded3d` traits now take `Isometry2d` and
`Isometry3d` parameters (respectively) instead of separate translation
and rotation arguments. Existing calls to `aabb_2d`, `bounding_circle`,
`aabb_3d`, and `bounding_sphere` will have to be changed to use
isometries instead. A straightforward conversion is to refactor just by
calling `Isometry2d/3d::new`, as follows:
```rust
// Old:
let aabb = my_shape.aabb_2d(my_translation, my_rotation);

// New:
let aabb = my_shape.aabb_2d(Isometry2d::new(my_translation, my_rotation));
```

However, if the old translation and rotation are 3d
translation/rotations originating from a `Transform` or
`GlobalTransform`, then `to_isometry` may be used instead. For example:
```rust
// Old:
let bounding_sphere = my_shape.bounding_sphere(shape_transform.translation, shape_transform.rotation);

// New:
let bounding_sphere = my_shape.bounding_sphere(shape_transform.to_isometry());
```

This discussion also applies to the `from_point_cloud` construction
method of `Aabb2d`/`BoundingCircle`/`Aabb3d`/`BoundingSphere`, which has
similarly been altered to use isometries.

Added serialize flag to bevy_math dep of bevy_ui (#14450)
# Objective

When depending on the `bevy_ui` crate specifically and using the
`serialize` feature flag, the compilation fails due to `bevy_math` not
having the serialize flag enabled.

## Solution

Added the `serialize` flag to the `bevy_math` dependency when using that
flag on `bevy_ui`.

## Testing

Tested by adding `bevy_math = { version = "0.14", features =
["serialize"] }` on a small Bevy library to ensure compilation was
successful.

bevy_reflect: Adding support for Atomic values (#14419)
Fixes #14418

Note that this does not add AtomicPtr, which would need its own special
casing support, just the regular value types.
Also, I was forced to be opinionated about which Ordering to use, so I
chose SeqCst as the strictest by default.

Disallow empty cubic and rational curves (#14382)
# Objective

Previously, our cubic spline constructors would produce
`CubicCurve`/`RationalCurve` output with no data when they themselves
didn't hold enough control points to produce a well-formed curve.
Attempting to sample the resulting empty "curves" (e.g. by calling
`CubicCurve::position`) would crash the program (😓).

The objectives of this PR are: 
1. Ensure that the curve output of `bevy_math`'s spline constructions
are never invalid as data.
2. Provide a type-level guarantee that `CubicCurve` and `RationalCurve`
actually function as curves.

## Solution

This has a few pieces. Firstly, the curve generator traits
`CubicGenerator`, `CyclicCubicGenerator`, and `RationalGenerator` are
now fallible — they have associated error types, and the
curve-generation functions are allowed to fail:
```rust
/// Implement this on cubic splines that can generate a cubic curve from their spline parameters.
pub trait CubicGenerator<P: VectorSpace> {
    /// An error type indicating why construction might fail.
    type Error;

    /// Build a [`CubicCurve`] by computing the interpolation coefficients for each curve segment.
    fn to_curve(&self) -> Result<CubicCurve<P>, Self::Error>;
}
```

All existing spline constructions use this together with errors that
indicate when they didn't have the right control data and provide curves
which have at least one segment whenever they return an `Ok` variant.

Next, `CubicCurve` and `RationalCurve` have been blessed with a
guarantee that their internal array of segments (`segments`) is never
empty. In particular, this field is no longer public, so that invalid
curves cannot be built using struct instantiation syntax. To compensate
for this shortfall for users (in particular library authors who might
want to implement their own generators), there is a new method
`from_segments` on these for constructing a curve from a list of
segments, failing if the list is empty:
```rust
/// Create a new curve from a collection of segments. If the collection of segments is empty,
/// a curve cannot be built and `None` will be returned instead.
pub fn from_segments(segments: impl Into<Vec<CubicSegment<P>>>) -> Option<Self> { //... }
```

All existing methods on `CyclicCurve` and `CubicCurve` maintain the
invariant, so the direct construction of invalid values by users is
impossible.

## Testing

Run unit tests from `bevy_math::cubic_splines`. Additionally, run the
`cubic_splines` example and try to get it to crash using small numbers
of control points: it uses the fallible constructors directly, so if
invalid data is ever constructed, it is basically guaranteed to crash.

---

## Migration Guide

The `to_curve` method on Bevy's cubic splines is now fallible (returning
a `Result`), meaning that any existing calls will need to be updated by
handling the possibility of an error variant.

Similarly, any custom implementation of `CubicGenerator` or
`RationalGenerator` will need to be amended to include an `Error` type
and be made fallible itself.

Finally, the fields of `CubicCurve` and `RationalCurve` are now private,
so any direct constructions of these structs from segments will need to
be replaced with the new `CubicCurve::from_segments` and
`RationalCurve::from_segments` methods.

---

## Design

The main thing to justify here is the choice for the curve internals to
remain the same. After all, if they were able to cause crashes in the
first place, it's worth wondering why safeguards weren't put in place on
the types themselves to prevent that.

My view on this is that the problem was really that the internals of
these methods implicitly relied on the assumption that the value they
were operating on was *actually a curve*, when this wasn't actually
guaranteed. Now, it's possible to make a bunch of small changes inside
the curve struct methods to account for that, but I think that's worse
than just guaranteeing that the data is valid upstream — sampling is
about as hot a code path as we're going to get in this area, and hitting
an additional branch every time it happens just to check that the struct
contains valid data is probably a waste of resources.

Another way of phrasing this is that even if we're only interested in
solving the crashes, the curve's validity needs to be checked at some
point, and it's almost certainly better to do this once at the point of
construction than every time the curve is sampled.

In cases where the control data is supplied dynamically, users would
already have to deal with empty curve outputs basically not working.
Anecdotally, I ran into this while writing the `cubic_splines` example,
and I think the diff illustrates the improvement pretty nicely — the
code no longer has to anticipate whether the output will be good or not;
it just has to handle the `Result`.

The cost of all this, of course, is that we have to guarantee that the
new invariant is actually maintained whenever we extend the API.
However, for the most part, I don't expect users to want to do much
surgery on the internals of their curves anyway.

Add FilteredAccess::empty and simplify the implementatin of update_component_access for AnyOf/Or (#14352)
# Objective

- The implementation of `update_component_access` for `AnyOf`/`Or` is
kinda weird due to special casing the first filter, let's simplify it;
- Fundamentally we want to fold/reduce the various filters using an OR
operation, however in order to do a proper fold we need a neutral
element for the initial accumulator, which for OR is FALSE. However we
didn't have a way to create a `FilteredAccess` value corresponding to
FALSE and thus the only option was reducing, which special cases the
first element as being the initial accumulator.

This is an alternative to https://github.com/bevyengine/bevy/pull/14026

## Solution

- Introduce `FilteredAccess::empty` as a way to create a
`FilteredAccess` corresponding to the logical proposition FALSE;
- Use it as the initial accumulator for the above operations, allowing
to handle all the elements to fold in the same way.

---

## Migration Guide

- The behaviour of `AnyOf<()>` and `Or<()>` has been changed to match no
archetypes rather than all archetypes to naturally match the
corresponding logical operation. Consider replacing them with `()`
instead.

Generate links to definition in source code pages on docs.rs and dev-docs.bevyengine.org (#12965)
# Objective

- Fix issue #2611

## Solution

- Add `--generate-link-to-definition` to all the `rustdoc-args` arrays
in the `Cargo.toml`s (for docs.rs)
- Add `--generate-link-to-definition` to the `RUSTDOCFLAGS` environment
variable in the docs workflow (for dev-docs.bevyengine.org)
- Document all the workspace crates in the docs workflow (needed because
otherwise only the source code of the `bevy` package will be included,
making the argument useless)
- I think this also fixes #3662, since it fixes the bug on
dev-docs.bevyengine.org, while on docs.rs it has been fixed for a while
on their side.

---

## Changelog

- The source code viewer on docs.rs now includes links to the
definitions.

Fix bevy_render's image dependency version (#14505)
# Objective

- `bevy_render` depends on `image 0.25` but uses `image::ImageReader`
which was added only in `image 0.25.2`
- users that have `image 0.25` in their `Cargo.lock` and update to the
latest `bevy_render` may thus get a compilation due to this (at least I
did)

## Solution

- Properly set the correct minimum version of `image` that `bevy_render`
depends on.

Don't debug SystemId's entity field twice (#14499)
# Objective

- `SystemId`'s `Debug` implementation includes its `entity` field twice.
- This was likely an oversight in #11019, since before that PR the
second field was the `PhantomData` one.

## Solution

- Only include it once

Alternatively, this could be changed to match the struct representation
of `SystemId`, thus instructing the formatter to print a named struct
and including the `PhantomData` field.

Fix TextureCache memory leak and add is_empty() method (#14480)
# Objective

Fix a memory leak in `TextureCache` caused by the internal HashMap never
having unused entries cleared.

This isn't a giant memory leak, given the unused entries are simply
empty vectors. Though, if someone goes and resizes a window a bunch, it
can lead to hundreds/thousands of TextureDescriptor keys adding up in
the hashmap – which isn't ideal.

## Solution

- Only retain hashmap entries that still have textures.
- I also added an `is_empty()` method to `TextureCache`, which is useful
for 3rd-party higher-level caches that might have individual caches by
view entity or texture type, for example.

## Testing

- Verified the examples still work (this is a trivial change)

Fix bevy_winit not building with serialize feature (#14469)
# Objective

- `bevy_winit` fails to build with just the `serialize` feature.
- Caught by [`flag-frenzy`](https://github.com/TheBevyFlock/flag-frenzy)
in [this
run](https://github.com/TheBevyFlock/flag-frenzy/actions/runs/10087486444/job/27891723948),
using the new, nuanced configuration system!

## Solution

- It was failing because `bevy_winit` did not pass the `serialize` flag
to two of its dependencies: `bevy_input` and `bevy_window`.
- To fix this, add these crates to the feature flag.

## Testing

```bash
# On Linux, you must also specify a backend: `x11` or `wayland`.
# You can do this with `-F serialize,x11`, etc.
cargo check -p bevy_winit --no-default-features -F serialize

Handle 0 height in prepare_bloom_textures (#14423)
# Objective

- Fix a confusing panic when the viewport width is non-zero and the
height is 0, `prepare_bloom_textures` tries to create a `4294967295x1`
texture.

## Solution

- Avoid dividing by zero
- Apps still crash after this, but now on a more reasonable error about
the zero-size viewport

## Testing

- I isolated and tested the math. A height of 0 sets `mip_height_ratio`
to `inf`, causing the width to explode if it isn't also 0

Fix bevy_gltf PBR features not enabling corresponding bevy_pbr flags (#14486)
# Objective

- `bevy_gltf` does not build with only the
`pbr_multi_layer_material_textures` or `pbr_anisotropy_texture`
features.
- Caught by [`flag-frenzy`](https://github.com/TheBevyFlock/flag-frenzy)
in [this
run](https://github.com/TheBevyFlock/flag-frenzy/actions/runs/10087486444/job/27891723948).

## Solution

- This error was due to the feature not enabling the corresponding
feature in `bevy_pbr`. Adding these flags as a dependency fixes this
error.

## Testing

The following commands fail on `main`, but pass with this PR:

```bash
cargo check -p bevy_gltf --no-default-features -F pbr_multi_layer_material_textures
cargo check -p bevy_gltf --no-default-features -F pbr_anisotropy_texture

Remove #[cfg] from the From impls of TextSection (#14439)
# Objective

- Not including bevy's default font shouldn't result in code not
compiling anymore.
- Games may want to load their own default font into the default
`Handle<Font>` and not include bevy's default font, but still use these
convenience impls (https://github.com/bevyengine/bevy/issues/12192
currently makes this a bit inconvenient, but it does work).

## Solution

- Include these impls unconditionally.
- Slightly expand the comment on the `font` field to indicate that a
custom font can be used to override the default font.
- (drive-by: add `#[reflect(Default)]` on `TextSection`, since it was
missing a way to construct it via reflection)

ptr: allow Ptr and PtrMut construction for references to values of ?Sized types (#14479)
# Objective

- Currently `bevy_ptr::{Ptr, PtrMut}` have `From` implementations from
references.
- These implementations impose an implicit `Sized` bound so `bevy_ptr`
types cannot be created from references to slices and trait objects.
- I ran into this trying to use `Ptr<'static>` as an untyped `&'static
dyn Any`, and [had to work around
it](f32b41512c/src/registry.rs (L214-L219)).

## Solution

Conversions for Isometry3d ⟷ Transform/GlobalTransform (#14478)
# Objective

Allow interoperation between `Isometry3d` and the transform types from
bevy_transform. At least in the short term, the primary goal is to allow
the extraction of isometries from transform components by users.

## Solution

- Add explicit `from_isometry`/`to_isometry` methods to `Transform`.
- Add explicit `from_isometry`/`to_isometry` methods to
`GlobalTransform`. The former is hidden (primarily for internal use),
and the latter has the caveats originating in
[`Affine3A::to_scale_rotation_translation`](https://docs.rs/glam/latest/glam/f32/struct.Affine3A.html#method.to_scale_rotation_translation).
- Implement the `TransformPoint` trait for `Isometry3d`.

## Solution

Use `crate::color_ops::lerp_hue` to handle the wrap-around at 360

Dedicated Reflect implementation for Set-like things (#13014)
# Objective

I just wanted to inspect `HashSet`s in `bevy-inspector-egui` but I
noticed that it didn't work for some reason. A few minutes later I found
myself looking into the bevy reflect impls noticing that `HashSet`s have
been covered only rudimentary up until now.

## Solution

I'm not sure if this is overkill (especially the first bullet), but
here's a list of the changes:

- created a whole new trait and enum variants for `ReflectRef` and the
like called `Set`
- mostly oriented myself at the `Map` trait and made the necessary
changes until RA was happy
- create macro `impl_reflect_for_hashset!` and call it on `std::HashSet`
and `hashbrown::HashSet`

Extra notes:

- no `get_mut` or `get_mut_at` mirroring the `std::HashSet`
- `insert[_boxed]` and `remove` return `bool` mirroring `std::HashSet`,
additionally that bool is reflect as I thought that would be how we
handle things in bevy reflect, but I'm not sure on this
- ser/de are handled via `SeqAccess`
- I'm not sure about the general deduplication property of this impl of
`Set` that is generally expected? I'm also not sure yet if `Map` does
provide this. This mainly refers to the `Dynamic[...]` structs
- I'm not sure if there are other methods missing from the `trait`, I
felt like `contains` or the set-operations (union/diff/...) could've
been helpful, but I wanted to get out the bare minimum for feedback
first

---

## Changelog

### Added
- `Set` trait for `bevy_reflect`

### Changed
- `std::collections::HashSet` and `bevy_utils::hashbrown::HashSet` now
implement a more complete set of reflect functionalities instead of
"just" `reflect_value`
- `TypeInfo` contains a new variant `Set` that contains `SetInfo`
- `ReflectKind` contains a new variant `Set`
- `ReflectRef` contains a new variant `Set`
- `ReflectMut` contains a new variant `Set`
- `ReflectOwned` contains a new variant `Set`

## Migration Guide

- The new `Set` variants on the enums listed in the change section
should probably be considered by people working with this level of the
lib
### Help wanted! 

I'm not sure if this change is able to break code. From my understanding
it shouldn't since we just add functionality but I'm not sure yet if

Add BorderRadius field to ImageBundle (#14457)
# Objective

- Fixes #14453

## Solution

- Added BorderRadius to ImageBundle

## Testing

- Did you test these changes? If so, how?

- Tested on a random picture I found in the examples and it added a
border radius.

- Are there any parts that need more testing?

- I don't fink so.

- How can other people (reviewers) test your changes? Is there anything
specific they need to know?

- Apply a border radius to a random picture.

Add intradoc links for observer triggers (#14458)
# Objective

When using observers you might want to know what the difference is
between `OnAdd` vs `OnReplace` vs `OnInsert` etc. It's not obvious where
to look (`component_hooks.rs`). Added intradoc links for easier
disambiguation.

Require &mut self for World::increment_change_tick (#14459)
# Objective

The method `World::increment_change_tick` currently takes `&self` as the
method receiver, which is semantically strange. Even though the interior
mutability is sound, the existence of this method is strange since we
tend to think of `&World` as being a read-only snapshot of a world, not
an aliasable reference to a world with mutability. For those purposes,
we have `UnsafeWorldCell`.

## Solution

Change the method signature to take `&mut self`. Use exclusive access to
remove the need for atomic adds, which makes the method slightly more
efficient. Redirect users to [`UnsafeWorldCell::increment_change_tick`]
if they need to increment the world's change tick from an aliased
context.

In practice I don't think there will be many breakages, if any. In cases
where you need to call `increment_change_tick`, you usually already have
either `&mut World` or `UnsafeWorldCell`.

---

## Migration Guide

The method `World::increment_change_tick` now requires `&mut self`
instead of `&self`. If you need to call this method but do not have
mutable access to the world, consider using
`world.as_unsafe_world_cell_readonly().increment_change_tick()`, which
does the same thing, but is less efficient than the method on `World`
due to requiring atomic synchronization.

```rust
fn my_system(world: &World) {
    // Before
    world.increment_change_tick();

    // After
    world.as_unsafe_world_cell_readonly().increment_change_tick();
}
```
