Fix blurry text (#12429)
# Objective

Fixes #12064

## Solution

Prior to #11326, the "global physical" translation of text was rounded.

After #11326, only the "offset" is being rounded.

This moves things around so that the "global translation" is converted
to physical pixels, rounded, and then converted back to logical pixels,
which is what I believe was happening before / what the comments above
describe.

## Discussion

This seems to work and fix an obvious mistake in some code, but I don't
fully grok the ui / text pipelines / math here.

## Before / After and test example

Reduce steady-state allocations in ui_stack_system (#12413)
# Objective

- Reduce allocations on the UI hot path.

## Solution

- Cache buffers used by the `ui_stack_system`.

## Follow-Up

- `sort_by_key` is potentially-allocating. It might be worthwhile to
include the child index as part of the sort-key and use unstable sort.

bevy_reflect: Remove U32Visitor (#12433)
# Objective

The `U32Visitor` struct has been unused since its introduction in #6140.
It's made itself known now by causing a recent [CI
failure](https://github.com/bevyengine/bevy/actions/runs/8243333274/job/22543736624).

## Solution

Remove the unused `U32Visitor` struct.

Also removed `PrepassLightsViewFlush` as it was causing a [similar CI
failure](https://github.com/bevyengine/bevy/actions/runs/8243838066/job/22545103746?pr=12433#step:6:269)

Allow setting RenderAssetUsages for gLTF meshes & materials during load (#12302)
# Objective

- Closes #11954

## Solution

Change the load_meshes field in `GltfLoaderSettings` from a bool to
`RenderAssetUsages` flag, and add a new load_materials flag.

Use these to determine where the gLTF mesh and material assets are
retained in memory (if the provided flags are empty, then the assets are
skipped during load).

---

## Migration Guide
When loading gLTF assets with `asset_server.load_with_settings`, use
`RenderAssetUsages` instead of `bool` when setting load_meshes e.g.
```rust
let _ = asset_server.load_with_settings("...", |s: &mut GltfLoaderSettings| {
    s.load_meshes = RenderAssetUsages::RENDER_WORLD;
});
``` 

Use the new load_materials field for controlling material load &
retention behaviour instead of load_meshes.

gLTF .meta files need similar updates e.g
```
load_meshes: true,
```
to
```
load_meshes: ("MAIN_WORLD | RENDER_WORLD"),
```

Send GamepadEvent for gamepads connected at startup (#12424)
# Objective

- Fix GamepadEvent::Connection not being sent for devices connected at
startup.

## Solution

- GamepadConnectionEvent was being sent directly for gamepads connected
at startup, which causes consumers of GamepadEvent to not receive those
events.
- Instead send GamepadEvent. The gamepad_event_system splits
GamepadEvent up, so consumers of GamepadConnectionEvent will still
receive the events.

Gizmo line joints (#12252)
# Objective

- Adds gizmo line joints, suggestion of #9400

## Solution

- Adds `line_joints: GizmoLineJoint` to `GizmoConfig`. Currently the
following values are supported:
- `GizmoLineJoint::None`: does not draw line joints, same behaviour as
previously
  - `GizmoLineJoint::Bevel`: draws a single triangle between the lines
- `GizmoLineJoint::Miter` / 'spiky joints': draws two triangles between
the lines extending them until they meet at a (miter) point.
- NOTE: for very small angles between the lines, which happens
frequently in 3d, the miter point will be very far away from the point
at which the lines meet.
- `GizmoLineJoint::Round(resolution)`: Draw a circle arc between the
lines. The circle is a triangle fan of `resolution` triangles.

---

## Changelog

- Added `GizmoLineJoint`, use that in `GizmoConfig` and added necessary
pipelines and draw commands.
- Added a new `line_joints.wgsl` shader containing three vertex shaders
`vertex_bevel`, `vertex_miter` and `vertex_round` as well as a basic
`fragment` shader.

## Migration Guide

Any manually created `GizmoConfig`s must now set the `.line_joints`
field.

## Known issues

- The way we currently create basic closed shapes like rectangles,
circles, triangles or really any closed 2d shape means that one of the
corners will not be drawn with joints, although that would probably be
expected. (see the triangle in the 2d image)
- This could be somewhat mitigated by introducing line caps or fixed by
adding another segment overlapping the first of the strip. (Maybe in a
followup PR?)
- 3d shapes can look 'off' with line joints (especially bevel) because
wherever 3 or more lines meet one of them may stick out beyond the joint
drawn between the other 2.
- Adding additional lines so that there is a joint between every line at
a corner would fix this but would probably be too computationally
expensive.
- Miter joints are 'unreasonably long' for very small angles between the
lines (the angle is the angle between the lines in screen space). This
is technically correct but distracting and does not feel right,
especially in 3d contexts. I think limiting the length of the miter to
the point at which the lines meet might be a good idea.
- The joints may be drawn with a different gizmo in-between them and
their corresponding lines in 2d. Some sort of z-ordering would probably
be good here, but I believe this may be out of scope for this PR.

- The black lines shooting out from the cube are miter joints that get
very long because the lines between which they are drawn are (almost)
collinear in screen space.

Add Rotation2d (#11658)
# Objective

Rotating vectors is a very common task. It is required for a variety of
things both within Bevy itself and in many third party plugins, for
example all over physics and collision detection, and for things like
Bevy's bounding volumes and several gizmo implementations.

For 3D, we can do this using a `Quat`, but for 2D, we do not have a
clear and efficient option. `Mat2` can be used for rotating vectors if
created using `Mat2::from_angle`, but this is not obvious to many users,
it doesn't have many rotation helpers, and the type does not give any
guarantees that it represents a valid rotation.

We should have a proper type for 2D rotations. In addition to allowing
for potential optimization, it would allow us to have a consistent and
explicitly documented representation used throughout the engine, i.e.
counterclockwise and in radians.

## Representation

The mathematical formula for rotating a 2D vector is the following:

```
new_x = x * cos - y * sin
new_y = x * sin + y * cos
```

Here, `sin` and `cos` are the sine and cosine of the rotation angle.
Computing these every time when a vector needs to be rotated can be
expensive, so the rotation shouldn't be just an `f32` angle. Instead, it
is often more efficient to represent the rotation using the sine and
cosine of the angle instead of storing the angle itself. This can be
freely passed around and reused without unnecessary computations.

The two options are either a 2x2 rotation matrix or a unit complex
number where the cosine is the real part and the sine is the imaginary
part. These are equivalent for the most part, but the unit complex
representation is a bit more memory efficient (two `f32`s instead of
four), so I chose that. This is like Nalgebra's
[`UnitComplex`](https://docs.rs/nalgebra/latest/nalgebra/geometry/type.UnitComplex.html)
type, which can be used for the
[`Rotation2`](https://docs.rs/nalgebra/latest/nalgebra/geometry/type.Rotation2.html)
type.

## Implementation

Add a `Rotation2d` type represented as a unit complex number:

```rust
/// A counterclockwise 2D rotation in radians.
///
/// The rotation angle is wrapped to be within the `]-pi, pi]` range.
pub struct Rotation2d {
    /// The cosine of the rotation angle in radians.
    ///
    /// This is the real part of the unit complex number representing the rotation.
    pub cos: f32,
    /// The sine of the rotation angle in radians.
    ///
    /// This is the imaginary part of the unit complex number representing the rotation.
    pub sin: f32,
}
```

Using it is similar to using `Quat`, but in 2D:

```rust
let rotation = Rotation2d::radians(PI / 2.0);

// Rotate vector (also works on Direction2d!)
assert_eq!(rotation * Vec2::X, Vec2::Y);

// Get angle as degrees
assert_eq!(rotation.as_degrees(), 90.0);

// Getting sin and cos is free
let (sin, cos) = rotation.sin_cos();

// "Subtract" rotations
let rotation2 = Rotation2d::FRAC_PI_4; // there are constants!
let diff = rotation * rotation2.inverse();
assert_eq!(diff.as_radians(), PI / 4.0);

// This is equivalent to the above
assert_eq!(rotation2.angle_between(rotation), PI / 4.0);

// Lerp
let rotation1 = Rotation2d::IDENTITY;
let rotation2 = Rotation2d::FRAC_PI_2;
let result = rotation1.lerp(rotation2, 0.5);
assert_eq!(result.as_radians(), std::f32::consts::FRAC_PI_4);

// Slerp
let rotation1 = Rotation2d::FRAC_PI_4);
let rotation2 = Rotation2d::degrees(-180.0); // we can use degrees too!
let result = rotation1.slerp(rotation2, 1.0 / 3.0);
assert_eq!(result.as_radians(), std::f32::consts::FRAC_PI_2);
```

There's also a `From<f32>` implementation for `Rotation2d`, which means
that methods can still accept radians as floats if the argument uses
`impl Into<Rotation2d>`. This means that adding `Rotation2d` shouldn't
even be a breaking change.

---

## Changelog

- Added `Rotation2d`
- Bounding volume methods now take an `impl Into<Rotation2d>`
- Gizmo methods with rotation now take an `impl Into<Rotation2d>`

## Future use cases

- Collision detection (a type like this is quite essential considering
how common vector rotations are)
- `Transform` helpers (e.g. return a 2D rotation about the Z axis from a
`Transform`)
- The rotation used for `Transform2d` (#8268)
- More gizmos, maybe meshes... everything in 2D that uses rotation

Fix leftover references to children when despawning audio entities (#12407)
# Objective

Fixes #12402

## Solution

Use `despawn_recursive` instead of `despawn` for despawning
`PlaybackMode::Despawn` audio.

## Migration Guide

`PlaybackSettings::DESPAWN` (`PlaybackMode::Despawn`) now despawns the
audio entity's children as well. If you were relying on the previous
behavior, you may be able to use `PlaybackMode::Remove`, or you may need
to use `PlaybackMode::Once` and manage your audio component lifecycle
manually.

Full backtraces (`RUST_BACKTRACE=full`) are unchanged.

## Alternative solutions

Write a custom panic hook. This could potentially let use exclude a few
more callstack frames but requires a dependency on `backtrace` and is
incompatible with user-provided panic hooks.

---

## Changelog

- Backtraces now exclude many Bevy internals (unless
`RUST_BACKTRACE=full` is used)

Add "all-features = true" to docs.rs metadata for most crates (#12366)
# Objective

Fix missing `TextBundle` (and many others) which are present in the main
crate as default features but optional in the sub-crate. See:

- https://docs.rs/bevy/0.13.0/bevy/ui/node_bundles/index.html
- https://docs.rs/bevy_ui/0.13.0/bevy_ui/node_bundles/index.html

~~There are probably other instances in other crates that I could track
down, but maybe "all-features = true" should be used by default in all
sub-crates? Not sure.~~ (There were many.) I only noticed this because
rust-analyzer's "open docs" features takes me to the sub-crate, not the
main one.

## Solution

Add "all-features = true" to docs.rs metadata for crates that use
features.

## Changelog

### Changed

- Unified features documented on docs.rs between main crate and
sub-crates

Contribution guidelines for bevy_audio (#12338)
# Objective

Provide guidelines for contributing code to `bevy_audio`, with a focus
on the critical sections of the audio engine.

## Changelog

Added to the crate-level documentation comment with a section
introducing audio programming, real-time safety and why it is important
to audio programming, as well as recommendations for some programming
use-cases. The section concludes with links to more resources about
audio programming.

I might have gone overboard with the writeup, but I didn't want to
assume a lot out of potential `bevy_audio` contributors, and so I spent
a bit of time defining terms as simply as I could.

I didn't want to pressure people to do so, but the first link on the
additional resources should really be "required reading" as it goes more
in depth about the why and how of audio programming.

Document ButtonInput behavior regarding window focus (#12367)
# Objective

`ButtonInput<KeyCode>` documentation is currently incorrect/incomplete,
see #12273.

## Solution

Fix the documentation.

I think in the future we should also stop triggering
`just_pressed`/`just_released` when focus switches between two Bevy
windows, as those functions are independent of the window. It could also
make sense to add individual `ButtonInput<KeyCode>`s per window.

Implement the AnimationGraph, allowing for multiple animations to be blended together. (#11989)
This is an implementation of RFC #51:
https://github.com/bevyengine/rfcs/blob/main/rfcs/51-animation-composition.md

Note that the implementation strategy is different from the one outlined
in that RFC, because two-phase animation has now landed.

# Objective

Bevy needs animation blending. The RFC for this is [RFC 51].

## Solution

This is an implementation of the RFC. Note that the implementation
strategy is different from the one outlined there, because two-phase
animation has now landed.

This is just a draft to get the conversation started. Currently we're
missing a few things:

- [x] A fully-fleshed-out mechanism for transitions
- [x] A serialization format for `AnimationGraph`s
- [x] Examples are broken, other than `animated_fox`
- [x] Documentation

---

## Changelog

### Added

* The `AnimationPlayer` has been reworked to support blending multiple
animations together through an `AnimationGraph`, and as such will no
longer function unless a `Handle<AnimationGraph>` has been added to the
entity containing the player. See [RFC 51] for more details.

* Transition functionality has moved from the `AnimationPlayer` to a new
component, `AnimationTransitions`, which works in tandem with the
`AnimationGraph`.

## Migration Guide

* `AnimationPlayer`s can no longer play animations by themselves and
need to be paired with a `Handle<AnimationGraph>`. Code that was using
`AnimationPlayer` to play animations will need to create an
`AnimationGraph` asset first, add a node for the clip (or clips) you
want to play, and then supply the index of that node to the
`AnimationPlayer`'s `play` method.

* The `AnimationPlayer::play_with_transition()` method has been removed
and replaced with the `AnimationTransitions` component. If you were
previously using `AnimationPlayer::play_with_transition()`, add all
animations that you were playing to the `AnimationGraph`, and create an
`AnimationTransitions` component to manage the blending between them.

Improve Bloom 3D lighting (#11981)
# Objective

- With the recent lighting changes, the default configuration in the
`bloom_3d` example is less clear what bloom actually does
- See [this
screenshot](4fdb1455d5 (r1494648414))
for a comparison.
- `bloom_3d` additionally uses a for-loop to spawn the spheres, which
can be turned into `commands::spawn_batch` call.
- The text is black, which is difficult to see on the gray background.

## Solution

- Increase emmisive values of materials.
- Set text to white.

## Showcase

Use .register_asset_source() in extra_asset_source example (#12350)
# Objective

Fixes #12347.

## Solution

Use `.register_asset_source()` in `extra_asset_source` example instead
of writing part of the app state.

Disentangle bevy_utils/bevy_core's reexported dependencies (#12313)
# Objective
Make bevy_utils less of a compilation bottleneck. Tackle #11478.

## Solution
* Move all of the directly reexported dependencies and move them to
where they're actually used.
* Remove the UUID utilities that have gone unused since `TypePath` took
over for `TypeUuid`.
* There was also a extraneous bytemuck dependency on `bevy_core` that
has not been used for a long time (since `encase` became the primary way
to prepare GPU buffers).
* Remove the `all_tuples` macro reexport from bevy_ecs since it's
accessible from `bevy_utils`.

---

## Changelog
Removed: Many of the reexports from bevy_utils (petgraph, uuid, nonmax,
smallvec, and thiserror).
Removed: bevy_core's reexports of bytemuck.

## Migration Guide
bevy_utils' reexports of petgraph, uuid, nonmax, smallvec, and thiserror
have been removed.

bevy_core' reexports of bytemuck's types has been removed. 

Add them as dependencies in your own crate instead.

Fix ImageLoader not being initialized with webp or pnm features (#12355)
# Objective

Fixes #12353

When only `webp` was selected, `ImageLoader` would not be initialized.

That is, users using `default-features = false` would need to add `png`
or `bmp` or something in addition to `webp` in order to use `webp`.

This was also the case for `pnm`. 

## Solution

Add `webp` and `pnm` to the list of features that trigger the
initialization of `ImageLoader`.

Add bevy_dev_tools crate (#11341)
# Objective

- Resolves #11309

## Solution

- Add `bevy_dev_tools` crate as a default feature.
- Add `DevToolsPlugin` and add it to an app if the `bevy_dev_tools`
feature is enabled.

`bevy_dev_tools` is reserved by @alice-i-cecile, should we wait until it
gets transferred to cart before merging?

Fix directional light shadow frustum culling near clip plane to infinity (#12342)
# Objective

- Fix slightly wrong logic from #11442
- Directional lights should not have a near clip plane

## Solution

- Push near clip out to infinity, so that the frustum normal is still
available if its needed for whatever reason in shader
- also opportunistically nabs a typo

Clean up type registrations (#12314)
# Objective
Fix #12304. Remove unnecessary type registrations thanks to #4154.

## Solution
Conservatively remove type registrations. Keeping the top level
components, resources, and events, but dropping everything else that is
a type of a member of those types.
