Expressively define plugins using functions (#11080)
# Objective

Plugins are an incredible tool for encapsulating functionality. They are
low-key one of Bevy's best features. Combined with rust's module and
privacy system, it's a match made in heaven.

The one downside is that they can be a little too verbose to define. 90%
of all plugin definitions look something like this:

```rust
pub struct MyPlugin;

impl Plugin for MyPlugin {
    fn build(&self, app: &mut App) {
        app.init_resource::<CameraAssets>()
           .add_event::<SetCamera>()
           .add_systems(Update, (collect_set_camera_events, drive_camera).chain());
    }
}
```

Every so often it gets a little spicier:

```rust
pub struct MyGenericPlugin<T>(PhantomData<T>);

impl<T> Default for MyGenericPlugin<T> { 
    fn default() -> Self { ... }
 }

impl<T> Plugin for MyGenericPlugin<T> { ... }
```

This is an annoying amount of boilerplate. Ideally, plugins should be
focused and small in scope, which means any app is going to have a *lot*
of them. Writing a plugin should be as easy as possible, and the *only*
part of this process that carries any meaning is the body of `fn build`.

## Solution

Implement `Plugin` for functions that take `&mut App` as a parameter.

The two examples above now look like this:

```rust
pub fn my_plugin(app: &mut App) {
    app.init_resource::<CameraAssets>()
       .add_event::<SetCamera>()
       .add_systems(Update, (collect_set_camera_events, drive_camera).chain());
} 

pub fn my_generic_plugin<T>(app: &mut App) {
    // No need for PhantomData, it just works.
}
```

Almost all plugins can be written this way, which I believe will make
bevy code much more attractive. Less boilerplate and less meaningless
indentation. More plugins with smaller scopes.

---

## Changelog

The `Plugin` trait is now implemented for all functions that take `&mut
App` as their only parameter. This is an abbreviated way of defining
plugins with less boilerplate than manually implementing the trait.

AssetPath source parse fix (#11543)
# Objective


Fixes #11533 


When `AssetPath`s are created from a string type, they are parsed into
an `AssetSource`, a `Path`, and a `Label`.
The current method of parsing has some unnecessary quirks:

- The presence of a `:` character is assumed to be the start of an asset
source indicator.
- This is not necessarily true. There are valid uses of a `:` character
in an asset path, for example an http source's port such as
`localhost:80`.
- If there are multiple instances of `://`, the last one is assumed to
be the asset source deliminator.
- This has some unexpected behavior. Even in a fully formed path, such
as `http://localhost:80`, the `:` between `localhost` and `80` is
assumed to be the start of an asset source, causing an error since it
does not form the full sequence `://`.


## Solution
Changes the `AssetPath`'s `parse_internal` method to be more permissive.
- Only the exact sequence `://` is taken to be the asset source
deliminator, and only the first one if there are multiple.
- As a consequence, it is no longer possible to detect a malformed asset
source deliminator, and so the corresponding error was removed.

Fix bug where Sprite::rect was ignored (#11480)
# Objective

https://github.com/bevyengine/bevy/pull/5103 caused a bug where
`Sprite::rect` was ignored by the engine. (Did nothing)

## Solution

My solution changes the way how Bevy calculates the rect, based on this
table:

| `atlas_rect` | `Sprite::rect` | Result |

|--------------|----------------|------------------------------------------------------|
| `None` | `None` | `None` |
| `None` | `Some` | `Sprite::rect` |
| `Some` | `None` | `atlas_rect` |
| `Some` | `Some` | `Sprite::rect` is used, relative to `atlas_rect.min`

AssetSaver and AssetTransformer split (#11260)
# Objective
One of a few Bevy Asset improvements I would like to make: #11216.

Currently asset processing and asset saving are handled by the same
trait, `AssetSaver`. This makes it difficult to reuse saving
implementations and impossible to have a single "universal" saver for a
given asset type.

## Solution
This PR splits off the processing portion of `AssetSaver` into
`AssetTransformer`, which is responsible for transforming assets. This
change involves adding the `LoadTransformAndSave` processor, which
utilizes the new API. The `LoadAndSave` still exists since it remains
useful in situations where no "transformation" of the asset is done,
such as when compressing assets.

## Notes:
As an aside, Bikeshedding is welcome on the names. I'm not entirely
convinced by `AssetTransformer`, which was chosen mostly because
`AssetProcessor` is taken. Additionally, `LoadTransformSave` may be
sufficient instead of `LoadTransformAndSave`.


---

## Changelog
### Added 
- `AssetTransformer` which is responsible for transforming Assets.
- `LoadTransformAndSave`, a `Process` implementation.
### Changed
- Changed `AssetSaver`'s responsibilities from processing and saving to
just saving.
- Updated `asset_processing` example to use new API.
- Old asset .meta files regenerated with new processor.

Update to wgpu 0.19 and raw-window-handle 0.6 (#11280)
# Objective

Keep core dependencies up to date.

## Solution

Update the dependencies.

wgpu 0.19 only supports raw-window-handle (rwh) 0.6, so bumping that was
included in this.

The rwh 0.6 version bump is just the simplest way of doing it. There
might be a way we can take advantage of wgpu's new safe surface creation
api, but I'm not familiar enough with bevy's window management to
untangle it and my attempt ended up being a mess of lifetimes and rustc
complaining about missing trait impls (that were implemented). Thanks to
@MiniaczQ for the (much simpler) rwh 0.6 version bump code.

Unblocks https://github.com/bevyengine/bevy/pull/9172 and
https://github.com/bevyengine/bevy/pull/10812

~~This might be blocked on cpal and oboe updating their ndk versions to
0.8, as they both currently target ndk 0.7 which uses rwh 0.5.2~~ Tested
on android, and everything seems to work correctly (audio properly stops
when minimized, and plays when re-focusing the app).

---

## Changelog

- `wgpu` has been updated to 0.19! The long awaited arcanization has
been merged (for more info, see
https://gfx-rs.github.io/2023/11/24/arcanization.html), and Vulkan
should now be working again on Intel GPUs.
- Targeting WebGPU now requires that you add the new `webgpu` feature
(setting the `RUSTFLAGS` environment variable to
`--cfg=web_sys_unstable_apis` is still required). This feature currently
overrides the `webgl2` feature if you have both enabled (the `webgl2`
feature is enabled by default), so it is not recommended to add it as a
default feature to libraries without putting it behind a flag that
allows library users to opt out of it! In the future we plan on
supporting wasm binaries that can target both webgl2 and webgpu now that
wgpu added support for doing so (see
https://github.com/bevyengine/bevy/issues/11505).
- `raw-window-handle` has been updated to version 0.6.

## Migration Guide

- `bevy_render::instance_index::get_instance_index()` has been removed
as the webgl2 workaround is no longer required as it was fixed upstream
in wgpu. The `BASE_INSTANCE_WORKAROUND` shaderdef has also been removed.
- WebGPU now requires the new `webgpu` feature to be enabled. The
`webgpu` feature currently overrides the `webgl2` feature so you no
longer need to disable all default features and re-add them all when
targeting `webgpu`, but binaries built with both the `webgpu` and
`webgl2` features will only target the webgpu backend, and will only
work on browsers that support WebGPU.
- Places where you conditionally compiled things for webgl2 need to be
updated because of this change, eg:
- `#[cfg(any(not(feature = "webgl"), not(target_arch = "wasm32")))]`
becomes `#[cfg(any(not(feature = "webgl") ,not(target_arch = "wasm32"),
feature = "webgpu"))]`
- `#[cfg(all(feature = "webgl", target_arch = "wasm32"))]` becomes
`#[cfg(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))]`
- `if cfg!(all(feature = "webgl", target_arch = "wasm32"))` becomes `if
cfg!(all(feature = "webgl", target_arch = "wasm32", not(feature =
"webgpu")))`
- `create_texture_with_data` now also takes a `TextureDataOrder`. You
can probably just set this to `TextureDataOrder::default()`
- `TextureFormat`'s `block_size` has been renamed to `block_copy_size`
- See the `wgpu` changelog for anything I might've missed:
https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md

Add new constructors for Circle and Sphere (#11526)
# Objective

Make APIs more consistent and ergonomic by adding a `new` constructor
for `Circle` and `Sphere`.

This could be seen as a redundant "trivial constructor", but in
practise, it seems valuable to me. I have lots of cases where formatting
becomes ugly because of the lack of a constructor, like this:

```rust
Circle {
    radius: self.radius(),
}
.contains_local_point(centered_pt)
```

With `new`, it'd be formatted much nicer:

```rust
Circle::new(self.radius()).contains_local_point(centered_pt)
```

Of course, this is just one example, but my circle/sphere definitions
very frequently span three or more lines when they could fit on one.

Adding `new` also increases consistency. `Ellipse` has `new` already,
and so does the mesh version of `Circle`.

## Solution

Add a `new` constructor for `Circle` and `Sphere`.

Add Animated Material example (#11524)
# Objective

- Fixes #11516

## Solution

- Add Animated Material example (colors are hue-cycling smoothly

Note: this example reproduces the perf issue found in #10610 pretty
consistently, with and without the changes from that PR included. Frame
time is sometimes around 4.3ms, other times around 12-14ms. Its pretty
random per run. I think this clears #10610 for merge.

Rename Schedule::name to Schedule::label (#11531)
# Objective

While working on #11527 I spotted that the internal field for the label
of a `Schedule` is called `name`. Using `label` seems more in line with
the other naming across Bevy.

## Solution

Renaming the field was straightforward since it's not exposed outside of
the module. This also means a changelog or migration guide isn't
necessary.

Add custom schedule example (#11527)
# Objective

Fixes #11411

## Solution

- Added a simple example how to create and configure custom schedules
that are run by the `Main` schedule.
- Spot checked some of the API docs used, fixed `App::add_schedule` docs
that referred to a function argument that was removed by #9600.

## Open Questions

- While spot checking the docs, I noticed that the `Schedule` label is
stored in a field called `name` instead of `label`. This seems
unintuitive since the term label is used everywhere else. Should we
change that field name? It was introduced in #9600. If so, I do think
this change would be out of scope for this PR that mainly adds the
example.

Fix cyclic dep (#11523)
# Objective

Rust analyzer kept complaining about a cyclic dependency due to
`bevy_input` having a dev-dependency on `bevy`.

`bevy_input` was also missing `bevy_reflect`'s "smol_str" feature which
it needs to compile on its own.

Fixes #10256

## Solution

Remove the dev-dependency on `bevy` from `bevy_input` since it was only
used to reduce imports for 1 test and 3 doc examples by 1 line each, as
`bevy_input` already has dependencies on everything needed for those
tests and doctests to work.

Add `bevy_reflect`'s "smol_str" feature to `bevy_input`'s dependency
list as it needs it to actually compile.

Optional override for global spatial scale (#10419)
# Objective

Fixes #10414.

That issue and its comments do a great job of laying out the case for
this.

## Solution

Added an optional `spatial_scale` field to `PlaybackSettings`, which
overrides the default value set on `AudioPlugin`.

## Changelog

- `AudioPlugin::spatial_scale` has been renamed to
`default_spatial_scale`.
- `SpatialScale` is no longer a resource and is wrapped by
`DefaultSpatialScale`.
- Added an optional `spatial_scale` to `PlaybackSettings`.

## Migration Guide

`AudioPlugin::spatial_scale` has been renamed to `default_spatial_scale`
and the default spatial scale can now be overridden on individual audio
sources with `PlaybackSettings::spatial_scale`.

If you were modifying or reading `SpatialScale` at run time, use
`DefaultSpatialScale` instead.

```rust
// before
app.add_plugins(DefaultPlugins.set(AudioPlugin {
    spatial_scale: SpatialScale::new(AUDIO_SCALE),
    ..default()
}));

// after
app.add_plugins(DefaultPlugins.set(AudioPlugin {
    default_spatial_scale: SpatialScale::new(AUDIO_SCALE),
    ..default()
}));

Tweak gamepad viewer example style (#11484)
# Objective

Since #10339, the contrast in this example has been very low. While I
was in there, I made a few other tweaks to the style.

Alternative to #10102.

## Solution

- Increase brightness of inactive buttons for higher contrast on the new
clear color
- Combine `DEAD_COLOR` and `EXTENT_COLOR`. These were using the same
value, and combining them might make the intent a little clearer. (This
is the single color for "not the live zone.")
- Make the "stick buttons" slightly smaller, so it's a bit more obvious
that they are sitting inside of the default dead zone.
- Remove explicit text color -- it was the same as the default
- Add top-left margin to the text in the top left, and change the font
size to better match other examples with text in the corner.

# Objective

- Using the latest nightly for `miri` is generally desirable as we want
to catch regressions upstream or new problems quickly
- https://github.com/rust-lang/rust/pull/120123 should be merged now, so
it should work.

## Solution

- Revert #11421.

Implement bounding volume intersections (#11439)
# Objective

#10946 added bounding volume types and an `IntersectsVolume` trait, but
didn't actually implement intersections between bounding volumes.

This PR implements AABB-AABB, circle-circle / sphere-sphere, and
AABB-circle / AABB-sphere intersections.

## Solution

Implement `IntersectsVolume` for bounding volume pairs. I also added
`closest_point` methods to return the closest point on the surface /
inside of bounding volumes. This is used for AABB-circle / AABB-sphere
intersections.

TextureAtlasBuilder now respects insertion order (#11474)
# Objective

TextureAtlases are commonly used to drive animations described as a
consecutive range of indices. The current TextureAtlasBuilder uses the
AssetId of the image to determine the index of the texture in the
TextureAtlas. The AssetId of an Image Asset can change between runs.
The TextureAtlas exposes
[`get_texture_index`](https://docs.rs/bevy/latest/bevy/sprite/struct.TextureAtlas.html#method.get_texture_index)
to get the index from a given AssetId, but this needlessly complicates
the process of creating a simple TextureAtlas animation.
Fixes #2459

## Solution

- Use the (ordered) image_ids of the 'texture to place' vector to
retrieve the packed locations and compose the textures of the
TextureAtlas.

Fix memory leak in dynamic ECS example (#11461)
# Objective

- Fix a memory leak in the dynamic ECS example mentioned in #11459

## Solution

- Rather than allocate the memory manually instead store a collection of
`Vec` that will be dropped after it is used.

---

I must have misinterpreted `OwningPtr`s semantics when initially writing
this example. I believe we should be able to provide better APIs here
for inserting dynamic components that don't require the user to wrangle
so much unsafety. We have no other examples using `insert_by_ids` and
our only tests show it being used for 1 or 2 values with nested calls to
`OwningPtr::make` despite the function taking an iterator. Rust's type
system is quite restrictive here but we could at least let
`OwningPtr::new` take non u8 `NonNull`.

I also agree with #11459 that we should generally be trying to simplify
and clarify this example.

refactor: Simplify lifetimes for Commands and related types (#11445)
# Objective

It would be convenient to be able to call functions with `Commands` as a
parameter without having to move your own instance of `Commands`. Since
this struct is composed entirely of references, we can easily get an
owned instance of `Commands` by shortening the lifetime.

## Solution

Add `Commands::reborrow`, `EntiyCommands::reborrow`, and
`Deferred::reborrow`, which returns an owned version of themselves with
a shorter lifetime.

Remove unnecessary lifetimes from `EntityCommands`. The `'w` and `'s`
lifetimes only have to be separate for `Commands` because it's used as a
`SystemParam` -- this is not the case for `EntityCommands`.

---

## Changelog

Added `Commands::reborrow`. This is useful if you have `&mut Commands`
but need `Commands`. Also added `EntityCommands::reborrow` and
`Deferred:reborrow` which serve the same purpose.

## Migration Guide

The lifetimes for `EntityCommands` have been simplified.

```rust
// Before (Bevy 0.12)
struct MyStruct<'w, 's, 'a> {
     commands: EntityCommands<'w, 's, 'a>,
}

// After (Bevy 0.13)
struct MyStruct<'a> {
    commands: EntityCommands<'a>,
}
```

The method `EntityCommands::commands` now returns `Commands` rather than
`&mut Commands`.

```rust
// Before (Bevy 0.12)
let commands = entity_commands.commands();
commands.spawn(...);

// After (Bevy 0.13)
let mut commands = entity_commands.commands();
commands.spawn(...);
```

Add Reflection for Wrapping/Saturating types (#11397)
# Objective

- Extend reflection to the standard library's `Wrapping` and
`Saturating` generic types.

This wasn't my use-case but someone in the discord was surprised that
this wasn't already done. I decided to make a PR because the other
`std::num` items were reflected and if there's a reason to exclude
`Wrapping` and `Saturating`, I am unaware of it.

## Solution

Trivial fix

Revert rendering-related associated type name changes (#11027)
# Objective

> Can anyone explain to me the reasoning of renaming all the types named
Query to Data. I'm talking about this PR
https://github.com/bevyengine/bevy/pull/10779 It doesn't make sense to
me that a bunch of types that are used to run queries aren't named Query
anymore. Like ViewQuery on the ViewNode is the type of the Query. I
don't really understand the point of the rename, it just seems like it
hides the fact that a query will run based on those types.

add storage_texture option to as_bind_group macro (#9943)
# Objective

- Add the ability to describe storage texture bindings when deriving
`AsBindGroup`.
- This is especially valuable for the compute story of bevy which
deserves some extra love imo.

## Solution

- This add the ability to annotate struct fields with a
`#[storage_texture(0)]` annotation.
- Instead of adding specific option parsing for all the image formats
and access modes, I simply accept a token stream and defer checking to
see if the option is valid to the compiler. This still results in useful
and friendly errors and is free to maintain and always compatible with
wgpu changes.

---

## Changelog

- The `#[storage_texture(..)]` annotation is now accepted for fields of
`Handle<Image>` in structs that derive `AsBindGroup`.
- The game_of_life compute shader example has been updated to use
`AsBindGroup` together with `[storage_texture(..)]` to obtain the
`BindGroupLayout`.

Fix weird visuals when drawing a gizmo with a non-normed normal.

`Direction3d::new(vec).unwrap_or(default)` or potentially
`Direction3d::new_unchecked(vec)` if you know your vec is definitely
normalized.

Direction: Rename from_normalized to new_unchecked (#11425)
# Objective

`Direction2d::from_normalized` & `Direction3d::from_normalized` don't
emphasize that importance of the vector being normalized enough.

## Solution

Rename `from_normalized` to `new_unchecked` and add more documentation.

---

`Direction2d` and `Direction3d` were added somewhat recently in
https://github.com/bevyengine/bevy/pull/10466 (after 0.12), so I don't
think documenting the changelog and migration guide is necessary (Since
there is no major previous version to migrate from).

But here it is anyway in case it's needed:

## Changelog

- Renamed `Direction2d::from_normalized` and
`Direction3d::from_normalized` to `new_unchecked`.

## Migration Guide

- Renamed `Direction2d::from_normalized` and
`Direction3d::from_normalized` to `new_unchecked`.

Add geometric primitives to bevy_math::prelude (#11432)
# Objective

Currently, the `primitives` module is inside of the prelude for
`bevy_math`, but the actual primitives are not. This requires either
importing the shapes everywhere that uses them, or adding the
`primitives::` prefix:

```rust
let rectangle = meshes.add(primitives::Rectangle::new(5.0, 2.5));
```

(Note: meshing isn't actually implemented yet, but it's in #11431)

The primitives are meant to be used for a variety of tasks across
several crates, like for meshing, bounding volumes, gizmos, colliders,
and so on, so I think having them in the prelude is justified. It would
make several common tasks a lot more ergonomic.

```rust
let rectangle = meshes.add(Rectangle::new(5.0, 2.5));
```

## Solution

Add `primitives::*` to `bevy_math::prelude`.

Add Aabb2d::new and Aabb3d::new constructors (#11433)
# Objective

Currently, the only way to create an AABB is to specify its `min` and
`max` coordinates. However, it's often more useful to use the center and
half-size instead.

## Solution

Add `new` constructors for `Aabb2d` and `Aabb3d`.

This:

```rust
let aabb = Aabb3d {
    min: center - half_size,
    max: center + half_size,
}
```

becomes this:

```rust
let aabb = Aabb3d::new(center, half_size);
```

I also made the usage of "half-extents" vs. "half-size" a bit more
consistent.

Change Ellipse representation and improve helpers (#11435)
# Objective

Currently, the `Ellipse` primitive is represented by a `half_width` and
`half_height`. To improve consistency (similarly to #11434), it might
make more sense to use a `Vec2` `half_size` instead.

Alternatively, to make the elliptical nature clearer, the properties
could also be called `radius_x` and `radius_y`.

Secondly, `Ellipse::new` currently takes a *full* width and height
instead of two radii. I would expect it to take the half-width and
half-height because ellipses and circles are almost always defined using
radii. I wouldn't expect `Circle::new` to take a diameter (if we had
that method).

## Solution

Change `Ellipse` to store a `half_size` and `new` to take the half-width
and half-height.

I also added a `from_size` method similar to `Rectangle::from_size`, and
added the `semi_minor` and `semi_major` helpers to get the
semi-minor/major radius.
