# Objective
- As part of the migration process we need to a) see the end effect of
the migration on user ergonomics b) check for serious perf regressions
c) actually migrate the code
- To accomplish this, I'm going to attempt to migrate all of the
remaining user-facing usages of `LegacyColor` in one PR, being careful
to keep a clean commit history.
- Fixes#12056.
## Solution
I've chosen to use the polymorphic `Color` type as our standard
user-facing API.
- [x] Migrate `bevy_gizmos`.
- [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs
- [x] Migrate sprites
- [x] Migrate UI
- [x] Migrate `ColorMaterial`
- [x] Migrate `MaterialMesh2D`
- [x] Migrate fog
- [x] Migrate lights
- [x] Migrate StandardMaterial
- [x] Migrate wireframes
- [x] Migrate clear color
- [x] Migrate text
- [x] Migrate gltf loader
- [x] Register color types for reflection
- [x] Remove `LegacyColor`
- [x] Make sure CI passes
Incidental improvements to ease migration:
- added `Color::srgba_u8`, `Color::srgba_from_array` and friends
- added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the
`Alpha` trait
- add and immediately deprecate (lol) `Color::rgb` and friends in favor
of more explicit and consistent `Color::srgb`
- standardized on white and black for most example text colors
- added vector field traits to `LinearRgba`: ~~`Add`, `Sub`,
`AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications
and divisions do not scale alpha. `Add` and `Sub` have been cut from
this PR.
- added `LinearRgba` and `Srgba` `RED/GREEN/BLUE`
- added `LinearRgba_to_f32_array` and `LinearRgba::to_u32`
## Migration Guide
Bevy's color types have changed! Wherever you used a
`bevy::render::Color`, a `bevy::color::Color` is used instead.
These are quite similar! Both are enums storing a color in a specific
color space (or to be more precise, using a specific color model).
However, each of the different color models now has its own type.
TODO...
- `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`,
`Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`,
`Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`.
- `Color::set_a` and `Color::a` is now `Color::set_alpha` and
`Color::alpha`. These are part of the `Alpha` trait in `bevy_color`.
- `Color::is_fully_transparent` is now part of the `Alpha` trait in
`bevy_color`
- `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for
`g`, `b` `h`, `s` and `l` have been removed due to causing silent
relatively expensive conversions. Convert your `Color` into the desired
color space, perform your operations there, and then convert it back
into a polymorphic `Color` enum.
- `Color::hex` is now `Srgba::hex`. Call `.into` or construct a
`Color::Srgba` variant manually to convert it.
- `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`,
`ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now
store a `LinearRgba`, rather than a polymorphic `Color`
- `Color::rgb_linear` and `Color::rgba_linear` are now
`Color::linear_rgb` and `Color::linear_rgba`
- The various CSS color constants are no longer stored directly on
`Color`. Instead, they're defined in the `Srgba` color space, and
accessed via `bevy::color::palettes::css`. Call `.into()` on them to
convert them into a `Color` for quick debugging use, and consider using
the much prettier `tailwind` palette for prototyping.
- The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with
the standard naming.
- Vector field arithmetic operations on `Color` (add, subtract, multiply
and divide by a f32) have been removed. Instead, convert your colors
into `LinearRgba` space, and perform your operations explicitly there.
This is particularly relevant when working with emissive or HDR colors,
whose color channel values are routinely outside of the ordinary 0 to 1
range.
- `Color::as_linear_rgba_f32` has been removed. Call
`LinearRgba::to_f32_array` instead, converting if needed.
- `Color::as_linear_rgba_u32` has been removed. Call
`LinearRgba::to_u32` instead, converting if needed.
- Several other color conversion methods to transform LCH or HSL colors
into float arrays or `Vec` types have been removed. Please reimplement
these externally or open a PR to re-add them if you found them
particularly useful.
- Various methods on `Color` such as `rgb` or `hsl` to convert the color
into a specific color space have been removed. Convert into
`LinearRgba`, then to the color space of your choice.
- Various implicitly-converting color value methods on `Color` such as
`r`, `g`, `b` or `h` have been removed. Please convert it into the color
space of your choice, then check these properties.
- `Color` no longer implements `AsBindGroup`. Store a `LinearRgba`
internally instead to avoid conversion costs.

# Objective
Just some mild annoyances:
- The `Color::Oklaba`, `Color::Oklcha` and `oklaba::Oklaba` doc comments
were inconsistent with the others
- The crate-level docs didn't include `Oklch` in the list of
representations and misspelt it in a later paragraph
## Solution
- Fix 'em
# Objective
- Cull 2D text outside the view frustum.
- Part of #11081.
## Solution
- Compute AABBs for entities with a `Text2DBundle` to enable culling
them.
`text2d` example with AABB gizmos on the text entities:
https://github.com/bevyengine/bevy/assets/18357657/52ed3ddc-2274-4480-835b-a7cf23338931
---
## Changelog
### Added
- 2D text outside the view are now culled with the
`calculate_bounds_text2d` system adding the necessary AABBs.
# Objective
`bevy_tasks` provides utilities for parallel mapping over slices. It can
be useful to have a chunk index available in the iteration function to
know which part of the original slice is being processed.
## Solution
Adds an index argument to the parallel map functions in `bevy_tasks`.
---
## Changelog
### Changed
- `par_chunk_map`, `par_splat_map`, `par_chunk_map_mut`, and
`par_splat_map_mut` now provide a chunk index during iteration.
## Migration Guide
Functions passed as arguments to `par_chunk_map`, `par_splat_map`,
`par_chunk_map_mut`, and `par_splat_map_mut` must now take an additional
index argument.
# Objective
Split up from #12017, rename Bevy's direction types.
Currently, Bevy has the `Direction2d`, `Direction3d`, and `Direction3dA`
types, which provide a type-level guarantee that their contained vectors
remain normalized. They can be very useful for a lot of APIs for safety,
explicitness, and in some cases performance, as they can sometimes avoid
unnecessary normalizations.
However, many consider them to be inconvenient to use, and opt for
standard vector types like `Vec3` because of this. One reason is that
the direction type names are a bit long and can be annoying to write (of
course you can use autocomplete, but just typing `Vec3` is still nicer),
and in some intances, the extra characters can make formatting worse.
The naming is also inconsistent with Glam's shorter type names, and
results in names like `Direction3dA`, which (in my opinion) are
difficult to read and even a bit ugly.
This PR proposes renaming the types to `Dir2`, `Dir3`, and `Dir3A`.
These names are nice and easy to write, consistent with Glam, and work
well for variants like the SIMD aligned `Dir3A`. As a bonus, it can also
result in nicer formatting in a lot of cases, which can be seen from the
diff of this PR.
Some examples of what it looks like: (copied from #12017)
```rust
// Before
let ray_cast = RayCast2d::new(Vec2::ZERO, Direction2d::X, 5.0);
// After
let ray_cast = RayCast2d::new(Vec2::ZERO, Dir2::X, 5.0);
```
```rust
// Before (an example using Bevy XPBD)
let hit = spatial_query.cast_ray(
Vec3::ZERO,
Direction3d::X,
f32::MAX,
true,
SpatialQueryFilter::default(),
);
// After
let hit = spatial_query.cast_ray(
Vec3::ZERO,
Dir3::X,
f32::MAX,
true,
SpatialQueryFilter::default(),
);
```
```rust
// Before
self.circle(
Vec3::new(0.0, -2.0, 0.0),
Direction3d::Y,
5.0,
Color::TURQUOISE,
);
// After (formatting is collapsed in this case)
self.circle(Vec3::new(0.0, -2.0, 0.0), Dir3::Y, 5.0, Color::TURQUOISE);
```
## Solution
Rename `Direction2d`, `Direction3d`, and `Direction3dA` to `Dir2`,
`Dir3`, and `Dir3A`.
---
## Migration Guide
The `Direction2d` and `Direction3d` types have been renamed to `Dir2`
and `Dir3`.
## Additional Context
This has been brought up on the Discord a few times, and we had a small
[poll](https://discord.com/channels/691052431525675048/1203087353850364004/1212465038711984158)
on this. `Dir2`/`Dir3`/`Dir3A` was quite unanimously chosen as the best
option, but of course it was a very small poll and inconclusive, so
other opinions are certainly welcome too.

# Objective
- Fixes#12170
## Solution
- Moved the existing `color_from_entity` internals into
`Hsla::sequence_dispersed` which generates a randomly distributed but
deterministic color sequence based.
- Replicated the method for `Lcha` and `Oklcha` as well.
## Examples
### Getting a few colours for a quick palette
```rust
let palette = Hsla::sequence_dispersed().take(5).collect::<Vec<_>>();
/*[
Hsla::hsl(0.0, 1., 0.5),
Hsla::hsl(222.49225, 1., 0.5),
Hsla::hsl(84.984474, 1., 0.5),
Hsla::hsl(307.4767, 1., 0.5),
Hsla::hsl(169.96895, 1., 0.5),
]*/
```
### Getting a colour from an `Entity`
```rust
let color = Oklcha::sequence_dispersed().nth(entity.index() as u32).unwrap();
```
## Notes
This was previously a private function exclusively for `Entity` types.
I've decided it should instead be public and operate on a `u32`
directly, since this function may have broader uses for debugging
purposes.

# Objective
fix#12182
- extract (or default) target camera for ui material nodes in the same
way as for other material nodes
- render ui material nodes only to their specified target
# Objective
Improve the `bevy::math::cubic_splines` module by making it more
flexible and adding new curve types.
Closes#10220
## Solution
Added new spline types and improved existing
---
## Changelog
### Added
- `CubicNurbs` rational cubic curve generator, allows setting the knot
vector and weights associated with every point
- `LinearSpline` curve generator, allows generating a linearly
interpolated curve segment
- Ability to push additional cubic segments to `CubicCurve`
- `IntoIterator` and `Extend` implementations for `CubicCurve`
### Changed
- `Point` trait has been implemented for more types: `Quat` and `Vec4`.
- `CubicCurve::coefficients` was moved to `CubicSegment::coefficients`
because the function returns `CubicSegment`, so it seems logical to be
associated with `CubicSegment` instead. The method is still not public.
### Fixed
- `CubicBSpline::new` was referencing Cardinal spline instead of
B-Spline

# Objective
When working on PRs, I'll often find that one of the early CI checks
fails, and work on fixing the result, but when I push the earlier
commits are still being processed by the CI. This would mean that if a
new commit is pushed while another CI process is already running on that
branch, the first set of jobs will be cancelled - reducing wasted
resources and wait time for CI on the latest commits.
## Solution
The solution is simply adding Github's concurrency groups to every
relevant workflow.
# Objective
- #12165 recently added links to Bevy errors in error messages.
- The links were in the form of `See:
https://bevyengine.org/learn/errors/#b000N`
- B0004 does not have the colon separating `See` and the link, unlike
the rest of the error messages
## Solution
- Add a colon, for consistency :)
# Objective
- More reflection
## Solution
- More. Reflection.
(not sure what bevy's policy on `derive(Debug)` is given that reflection
already lets you accomplish something largely equivalent; maybe
`derive(Reflect)` should generate a `Debug` impl that goes through
`Reflect::debug` unless you opt out?)
# Objective
The `css` contains all of the `basic` colors. Rather than defining them
twice, we can re-export them.
Suggested by @viridia <3
## Solution
- Re-export basic color palette within the css color palette.
- Remove the duplicate colors
- Fix alphabetization of the basic color palette file while I'm here

# Objective
- Complete compatibility with CSS Module 4
## Solution
- Added `Oklcha` which implements the Oklch color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Oklcha` to `Oklaba` using the provided `From` implementations
and then handle accordingly.
## Notes
This is the _last_ color space missing from the CSS Module 4 standard,
and is also the one I believe we should recommend users actually work
with for hand-crafting colours. It has all the uniformity benefits of
Oklab combined with the intuition chroma and hue provide (when compared
to a-axis and b-axis parameters).
# Objective
- Implement grid gizmos, suggestion of #9400
## Solution
- Added `gizmos.grid(...) ` and `gizmos.grid_2d(...)`
- The grids may be configured using `.outer_edges(...)` to specify
whether to draw the outer border/edges of the grid and `.skew(...)`to
specify the skew of the grid along the x or y directions.
---
## Changelog
- Added a `grid` module to `bevy_gizmos` containing `gizmos.grid(...) `
and `gizmos.grid_2d(...)` as well as assorted items.
- Updated the `2d_gizmos` and `3d_gizmos` examples to use grids.
## Additional
The 2D and 3D examples now look like this:

# Objective
As suggested in #12163 by @cart, we should add convenience constructors
to `bevy_color::Color` to match the existing API (easing migration pain)
and generally improve ergonomics.
## Solution
- Add `const fn Color::rgba(red, green, blue, alpha)` and friends, which
directly construct the appropriate variant.
- Add `const fn Color::rgb(red, green, blue)` and friends, which impute
and alpha value of 1.0.
- Add `const BLACK, WHITE, NONE` to `Color`. These are stored in
`LinearRgba` to reduce pointless conversion costs and inaccuracy.
- Changed the default `Color` from `Srgba::WHITE` to the new linear
equivalent for the same reason.

# Objective
As we start to migrate to `bevy_color` in earnest (#12056), we should
make it visible to Bevy users, and usable in examples.
## Solution
1. Add a prelude to `bevy_color`: I've only excluded the rarely used
`ColorRange` type and the testing-focused color distance module. I
definitely think that some color spaces are less useful than others to
end users, but at the same time the types used there are very unlikely
to conflict with user-facing types.
2. Add `bevy_color` to `bevy_internal` as an optional crate.
3. Re-export `bevy_color`'s prelude as part of `bevy::prelude`.

# Objective
- In #9623 I forgot to change the `FromWorld` requirement for
`ReflectResource`, fix that;
- Fix#12129
## Solution
- Use the same approach as in #9623 to try using `FromReflect` and
falling back to the `ReflectFromWorld` contained in the `TypeRegistry`
provided
- Just reflect `Resource` on `State<S>` since now that's possible
without introducing new bounds.
---
## Changelog
- `ReflectResource`'s `FromType<T>` implementation no longer requires
`T: FromWorld`, but instead now requires `FromReflect`.
- `ReflectResource::insert`, `ReflectResource::apply_or_insert` and
`ReflectResource::copy` now take an extra `&TypeRegistry` parameter.
## Migration Guide
- Users of `#[reflect(Resource)]` will need to also implement/derive
`FromReflect` (should already be the default).
- Users of `#[reflect(Resource)]` may now want to also add `FromWorld`
to the list of reflected traits in case their `FromReflect`
implementation may fail.
- Users of `ReflectResource` will now need to pass a `&TypeRegistry` to
its `insert`, `apply_or_insert` and `copy` methods.
# Objective
- Fixes#9670
- Avoid a crash in CI due to
```

## Solution
- Use an `R32Float` texture instead of an `Rgba8Unorm` as it's a tier 1
texture format https://github.com/gpuweb/gpuweb/issues/3838 and is more
supported
- This should also improve support for webgpu in the next wgpu version
# Objective
- Make PR CI faster
## Solution
- Run example on macOS, Windows examples are now run on PR merge
instead. This is the biggest change in duration
- Run miri on macOS. It doesn't change much the duration, but will free

# Objective
`downcast-rs` is not used within bevy_ecs. This is probably a remnant
from before Schedule v3 landed, since stages needed the downcasting.
## Solution
Remove it.
Shows relationships between color spaces and explains what files should
contain which conversions.
# Objective
- Provide documentation for maintainers and users on how color space
conversion is implemented.
## Solution
- Created a mermaid diagram documenting the relationships between
various color spaces. This diagram also includes links to defining
articles, and edges include links to conversion formulae.
- Added a `conversion.md` document which is included in the
documentation of each of the color spaces. This ensures it is readily
visible in all relevant contexts.
## Notes
The diagram is in the Mermaid (`.mmd`) format, and must be converted
into an SVG file (or other image format) prior to use in Rust
documentation. I've included a link to
[mermaid.live](https://mermaid.live) as an option for doing such
conversion in an appropriate README.
Below is a screenshot of the documentation added.
# Objective
On some platforms (observed on Windows and Linux, works fine on web),
velocity of all entities would be initialized to zero, making them
simply fall into the star.
## Solution
Using `Time<Fixed>::timestep` instead of `Time::delta_seconds` to
initialize velocity. Since the entities are generated in the startup
schedule, no time has elapsed yet and `Time::delta_seconds` would return
zero on some platforms. `Time<Fixed>::timestep` will always return the
expected time step of `FixedUpdate` schedule.
# Objective
`FromWorld` is often used to group loading and creation of assets for
resources.
With this setup, users often end up repetitively calling
`.resource::<AssetServer>` and `.resource_mut::<Assets<T>>`, and may
have difficulties handling lifetimes of the returned references.
## Solution
Add extension methods to `World` to add and load assets, through a new
extension trait defined in `bevy_asset`.
### Other considerations
* This might be a bit too "magic", as it makes implicit the resource
access.
* We could also implement `DirectAssetAccessExt` on `App`, but it didn't
feel necessary, as `FromWorld` is the principal use-case here.
---
## Changelog
* Add the `DirectAssetAccessExt` trait, which adds the `add_asset`,
`load_asset` and `load_asset_with_settings` method to the `World` type.
# Objective
This PR arose as part of the migration process for `bevy_color`: see
#12056.
While examining how `bevy_gizmos` stores color types internally, I found
that rather than storing a `Color` internally, it actually stores a
`[f32;4]` for a linear RGB, type aliased to a `ColorItem`.
While we don't *have* to clean this up to complete the migration, now
that we have explicit strong typing for linear color types we should use
them rather than replicating this idea throughout the codebase.
## Solution
- Added `LinearRgba::NAN`, for when you want to do cursed rendering
things.
- Replaced the internal color representation in `bevy_gizmo`: this was
`ColorItem`, but is now `LinearRgba`.
- `LinearRgba` is now `Pod`, enabling us to use the same fast `bytemuck`
bit twiddling tricks that we were using before. This requires:
1. Forcing `LinearRgba` to be `repr(C)`
2. Implementing `Zeroable`, and unsafe trait which defines what the
struct looks like when all values are zero.
3. Implementing `Pod`, a marker trait with stringent safety requirements
that is required for "plain old data".

# Objective
- Improve compatibility with CSS Module 4
- Simplify `Lcha` conversion functions
## Solution
- Added `Laba` which implements the Lab color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Laba` to either `Xyza` or `Lcha` using the provided `From`
implementations and then handle accordingly.
## Notes
The Lab color space is a required stepping stone when converting between
XYZ and Lch, therefore we already use the Lab color model, just in an
nameless fashion prone to errors.
This PR also includes a slightly broader refactor of the `From`
implementations between the various colour spaces to better reflect the
graph of definitions. My goal was to keep domain specific knowledge of
each colour space contained to their respective files (e.g., the
`From<Oklaba> for LinearRgba` definition was in `linear_rgba.rs` when it
probably belongs in `oklaba.rs`, since Linear sRGB is a fundamental
space and Oklab is defined in its relation to it)
# Objective
The `AssetIndex` cannot be carried across boundaries that do not allow
explicit rust types.
For context, I ran into this issue while trying to implent an
improvement for bevy_egui which leverages the not-so-new custom loader
API. Passing through a handle directly isn't possible, but instead it
requires stringified URI s. I had to work around the lack of this API s
existance using reflection, which is rather dirty.
## Solution
- Add `to_bits` and `from_bits` functions to `AssetIndex` to allow
moving this type through such boundaries.
---------

# Objective
- Make these types usable in reflection-based workflows.
## Solution
- The usual. Also reflect `Default` and `Component` behaviors so that
the types can be constructed, inserted, and removed.
# Objective
Added reflect support for `std::HashSet`, `BTreeSet` and `BTreeMap`.
The set support is limited to `reflect_value` since that's the level of
support prior art `bevy_util::HashSet` got.
## Changelog
Dropped `Hash` Requirement on `MapInfo` since it's not needed on
`BTreeMap`s.
# Objective
Memory usage optimisation
## Solution
`HashMap` and `HashSet`'s keys are immutable. So using mutable types
like `String`, `Vec<T>`, or `PathBuf` as a key is a waste of memory:
they have an extra `usize` for their capacity and may have spare
capacity.
This PR replaces these types by their immutable equivalents `Box<str>`,
`Box<[T]>`, and `Box<Path>`.
For more context, I recommend watching the [Use Arc Instead of
Vec](https://www.youtube.com/watch?v=A4cKi7PTJSs) video.

- Use `FromReflect` to convert proxy types to concrete ones in
`ReflectSerialize::get_serializable`.
- Use `get_represented_type_info() -> type_id()` to get the correct type
id to interact with the registry in
`bevy_reflect::serde::ser::get_serializable`.
---
## Changelog
- Registering `ReflectSerialize` now imposes additional `FromReflect`
and `TypePath` bounds.
## Migration Guide
- If `ReflectSerialize` is registered on a type, but `TypePath` or
`FromReflect` implementations are omitted (perhaps by
`#[reflect(type_path = false)` or `#[reflect(from_reflect = false)]`),
the traits must now be implemented.

# Objective
Fix#11845.
## Solution
Remove the `UpdateAssets` and `AssetEvents` schedules. Moved the
`UpdateAssets` systems to `PreUpdate`, and `AssetEvents` systems into
`First`. The former is meant to run before any of the event flushes.
## Future Work
It'd be ideal if we could manually flush the events for assets to avoid
needing two, sort of redundant, systems. This should at least let them
potentially run in parallel with all of the systems in the schedules
they were moved to.
---
## Changelog
Removed: `UpdateAssets` schedule from the main schedule. All systems
have been moved to `PreUpdate`.
Removed: `AssetEvents` schedule from the main schedule. All systems have
been move to `First` with the same system sets.
## Migration Guide
TODO
# Objective
The example showcase doesn't seem to work well with the portrait aspect
ratio used in this example, which is possibly something to be fixed
there, but there's also no reason this *needs* a custom size.
This custom window size is also sightly too tall for my particular
display which is a very common display size when accounting for the
macOS task bar and window title, so the content at the bottom is
clipped.
## Solution
- Remove the custom window size
- Swap the order of the justify / align nested loops so that the content
fits the new aspect ratio
- Make the containers responsive to window size, and make all the gaps
even

# Objective
- The `many_lights` example uses a for-loop around `commands.spawn`.
- It is generally recommended to use `spawn_batch` instead to lazily
spawn entities, because it doesn't massively grow the command queue.
## Solution
- Use `spawn_batch` in `many_lights` example.
---
## Discussion
- `thread_rng` is called for each light spawned. This is a simple
thread-local `Rc` clone, so it should compile down to a copy and an
increment + decrement instruction.
- I created `golden_ration` outside of the closure and `move`d it in.
This should just be a copy and hopefully will get const-evaluated away.
Would it be better to just move it into the closure itself?
## Performance
Using `spawn_batch` seems to decrease time-to-first-`Update` by 0.1s:
1.3s to 1.2s.

# Objective
- Partially addresses https://github.com/bevyengine/bevy/issues/11470
(I'd like to add Spatiotemporal Blue Noise in the future, but that's a
bit more controversial).
- Fix cluster_debug_visualization which has not compiled for a while
---
## Changelog
- Added random white noise shader functions to `bevy_pbr::utils`
## Migration Guide
- The `bevy_pbr::utils::random1D` shader function has been replaced by
the similar `bevy_pbr::utils::rand_f`.
# Objective
- During rendering of different gizmo groups, the ordering is random
between executions
## Solution
- Make the ordering stable
- It's using a `TypeIdMap`, its iteration order depends on the insertion
order. so insert when adding a group instead of when adding a gizmo
- Also changed `extract_gizmo_data` to not be group dependent. there
will be only one of those systems, no matter the number of gizmo groups
added

# Objective
`CameraProjectionPlugin<T>`'s bounds are `T: CameraProjection`. But the
bounds for `CameraProjectionPlugin` implementing `Plugin` are `T:
CameraProjection + Component + GetTypeRegistration`. This means that if
`T` is valid for `CameraProjectionPlugin`'s bounds, but not the plugin
implementation's bounds, then `CameraProjectionPlugin` would not
implement `Plugin`. Which is weird because you'd expect a struct with
`Plugin` in the name to implement `Plugin`.
## Solution
Make `CameraProjectionPlugin<T>`'s bounds `T: CameraProjection +
Component + GetTypeRegistration`. I also rearranged some of the code.
---
## Changelog
- Changed `CameraProjectionPlugin<T>`'s bounds to `T: CameraProjection +
Component + GetTypeRegistration`
## Migration Guide
`CameraProjectionPlugin<T>`'s trait bounds now require `T` to implement
`CameraProjection`, `Component`, and `GetTypeRegistration`. This
shouldn't affect most existing code as `CameraProjectionPlugin<T>` never
implemented `Plugin` unless those bounds were met.
# Objective
Split up from #12017, add an aligned version of `Direction3d` for SIMD,
and move direction types out of `primitives`.
## Solution
Add `Direction3dA` and move direction types into a new `direction`
module.
---
## Migration Guide
The `Direction2d`, `Direction3d`, and `InvalidDirectionError` types have
been moved out of `bevy::math::primitives`.
Before:
```rust
use bevy::math::primitives::Direction3d;
```
After:
```rust
use bevy::math::Direction3d;
```

# Objective
- Improve compatibility with CSS Module 4
- Simplify `Hsla` conversion functions
## Solution
- Added `Hsva` which implements the HSV color model.
- Added `Hwba` which implements the HWB color model.
- Updated `Color` and `LegacyColor` accordingly.
## Migration Guide
- Convert `Hsva` / `Hwba` to either `Hsla` or `Srgba` using the provided
`From` implementations and then handle accordingly.
## Notes
While the HSL color space is older than HWB, the formulation for HWB is
more directly related to RGB. Likewise, HSV is more closely related to
HWB than HSL. This makes the conversion of HSL to/from RGB more
naturally represented as the compound operation HSL <-> HSV <-> HWB <->
RGB. All `From` implementations for HSL, HSV, and HWB have been designed
to take the shortest path between itself and the target space.

# Objective
- We should move towards a consistent use of the new `bevy_color` crate.
- As discussed in #12089, splitting this work up into small pieces makes
it easier to review.
## Solution
- Port all uses of `LegacyColor` in the `bevy_core_pipeline` to
`LinearRgba`
- `LinearRgba` is the correct type to use for internal rendering types
- Added `LinearRgba::BLACK` and `WHITE` (used during migration)
- Add `LinearRgba::grey` to more easily construct balanced grey colors
(used during migration)
- Add a conversion from `LinearRgba` to `wgpu::Color`. The converse was
not done at this time, as this is typically a user error.
I did not change the field type of the clear color on the cameras: as
this is user-facing, this should be done in concert with the other
configurable fields.
## Migration Guide
`ColorAttachment` now stores a `LinearRgba` color, rather than a Bevy
0.13 `Color`.
`set_blend_constant` now takes a `LinearRgba` argument, rather than a
Bevy 0.13 `Color`.

# Objective
Right now when using egui, systems are inserted without any identifier
and to the root. I'd like to name those systems and insert them as
children to a root entity. This helps to keep the editor organized.
## Solution
- Although the `SystemId` is documented as an opaque type, examples
depicted above benefit from tear down of the abstraction.
---
## Changelog
### Added
- Implemented `From<SystemId>` for `Entity`
