Migrate the rest of the engine to UnsafeWorldCell (#8833)
# Objective

Follow-up to #6404 and #8292.

Mutating the world through a shared reference is surprising, and it
makes the meaning of `&World` unclear: sometimes it gives read-only
access to the entire world, and sometimes it gives interior mutable
access to only part of it.

This is an up-to-date version of #6972.

## Solution

Use `UnsafeWorldCell` for all interior mutability. Now, `&World`
*always* gives you read-only access to the entire world.

---

## Changelog

TODO - do we still care about changelogs?

## Migration Guide

Mutating any world data using `&World` is now considered unsound -- the
type `UnsafeWorldCell` must be used to achieve interior mutability. The
following methods now accept `UnsafeWorldCell` instead of `&World`:

- `QueryState`: `get_unchecked`, `iter_unchecked`,
`iter_combinations_unchecked`, `for_each_unchecked`,
`get_single_unchecked`, `get_single_unchecked_manual`.
- `SystemState`: `get_unchecked_manual`

```rust
let mut world = World::new();
let mut query = world.query::<&mut T>();

// Before:
let t1 = query.get_unchecked(&world, entity_1);
let t2 = query.get_unchecked(&world, entity_2);

// After:
let world_cell = world.as_unsafe_world_cell();
let t1 = query.get_unchecked(world_cell, entity_1);
let t2 = query.get_unchecked(world_cell, entity_2);
```

The methods `QueryState::validate_world` and
`SystemState::matches_world` now take a `WorldId` instead of `&World`:

```rust
// Before:
query_state.validate_world(&world);

// After:
query_state.validate_world(world.id());
```

The methods `QueryState::update_archetypes` and
`SystemState::update_archetypes` now take `UnsafeWorldCell` instead of
`&World`:

```rust
// Before:
query_state.update_archetypes(&world);

// After:
query_state.update_archetypes(world.as_unsafe_world_cell_readonly());
```

Ui Node Borders (#7795)
# Objective

Implement borders for UI nodes.

Relevant discussion: #7785
Related: #5924, #3991

<img width="283" alt="borders"
src="https://user-images.githubusercontent.com/27962798/220968899-7661d5ec-6f5b-4b0f-af29-bf9af02259b5.PNG">

## Solution

Add an extraction function to draw the borders.

---

Can only do one colour rectangular borders due to the limitations of the
Bevy UI renderer.

Maybe it can be combined with #3991 eventually to add curved border
support.

## Changelog
* Added a component `BorderColor`.
* Added the `extract_uinode_borders` system to the UI Render App.
* Added the UI example `borders`

Rename a leftover usage of a renamed function read_change_tick (#8837)
# Objective

The method `UnsafeWorldCell::read_change_tick` was renamed in #8588, but
I forgot to update a usage of this method in a doctest.

## Solution

Add get_ref to EntityRef (#8818)
# Objective

To mirror the `Ref` added as `WorldQuery`, and the `Mut` in
`EntityMut::get_mut`, we add `EntityRef::get_ref`, which retrieves `T`
with tick information, but *immutably*.

## Solution

- Add the method in question, also add it to`UnsafeEntityCell` since
this seems to be the best way of getting that information.

Also update/add safety comments to neighboring code.

---

## Changelog

- Add `EntityRef::get_ref` to get an `Option<Ref<T>>` from `EntityRef`

Instanced line rendering for gizmos based on bevy_polyline (#8427)
# Objective

Adopt code from
[bevy_polyline](https://github.com/ForesightMiningSoftwareCorporation/bevy_polyline)
for gizmo line-rendering.
This adds configurable width and perspective rendering for the lines.

Many thanks to @mtsr for the initial work on bevy_polyline. Thanks to
@aevyrie for maintaining it, @nicopap for adding the depth_bias feature
and the other
[contributors](https://github.com/ForesightMiningSoftwareCorporation/bevy_polyline/graphs/contributors)
for squashing bugs and keeping bevy_polyline up-to-date.

#### Before

![Before](https://user-images.githubusercontent.com/29694403/232831591-a8e6ed0c-3a09-4413-80fa-74cb8e0d33dd.png)
#### After - with line perspective

![After](https://user-images.githubusercontent.com/29694403/232831692-ba7cbeb7-e63a-4f8e-9b1b-1b80c668f149.png)

Line perspective is not on by default because with perspective there is
no default line width that works for every scene.

<details><summary>After - without line perspective</summary>
<p>

![After - no
perspective](https://user-images.githubusercontent.com/29694403/232836344-0dbfb4c8-09b7-4cf5-95f9-a4c26f38dca3.png)

</p>
</details>

Somewhat unexpectedly, the performance is improved with this PR.
At 200,000 lines in many_gizmos I get ~110 FPS on main and ~200 FPS with
this PR.
I'm guessing this is a CPU side difference as I would expect the
rendering technique to be more expensive on the GPU to some extent, but
I am not entirely sure.

Require read-only queries in QueryState::par_iter (#8832)
# Objective

The method `QueryState::par_iter` does not currently force the query to
be read-only. This means you can unsoundly mutate a world through an
immutable reference in safe code.

```rust
fn bad_system(world: &World, mut query: Local<QueryState<&mut T>>) {
    query.par_iter(world).for_each_mut(|mut x| *x = unsoundness);
}
```

## Solution

Use read-only versions of the `WorldQuery` types.

---

## Migration Guide

The function `QueryState::par_iter` now forces any world accesses to be
read-only, similar to how `QueryState::iter` works. Any code that
previously mutated the world using this method was *unsound*. If you
need to mutate the world, use `par_iter_mut` instead.

Implement Clone for CombinatorSystem (#8826)
# Objective

Make a combined system cloneable if both systems are cloneable on their
own. This is necessary for using chained conditions (e.g
`cond1.and_then(cond2)`) with `distributive_run_if()`.

## Solution

Implement `Clone` for `CombinatorSystem<Func, A, B>` where `A, B:
Clone`.

Rename Plane struct to HalfSpace (#8744)
# Objective

- Rename the `render::primitives::Plane` struct as to not confuse it
with `bevy_render::mesh::shape::Plane`
- Fixes https://github.com/bevyengine/bevy/issues/8730

## Solution

- Refactor the `render::primitives::Plane` struct to
`render::primitives::HalfSpace`
- Modify documentation to reflect this change

## Changelog

- Renamed `Plane` to `HalfSpace` to more accurately represent it's use
- Renamed `planes` member in `Frustum` to `half_spaces` to reflect
changes

## Migration Guide

- `Plane` has been renamed to `HalfSpace`
- `planes` member in `Frustum` has been renamed to `half_spaces`

Make setup of Opaque3dPrepass and AlphaMask3dPrepass phase items consistent with others (#8408)
# Objective

When browsing the bevy source code to try and learn about
`bevy_core_pipeline`, I noticed that the `DrawFunctions` resources,
`sort_phase_system`s and texture preparation for the `Opaque3d` and
`AlphaMask3d` phase items are all set up in `bevy_core_pipeline`, while
the `Opaque3dPrepass` and `AlphaMask3dPrepass` phase items are only
*declared* in `bevy_core_pipeline`, and actually registered properly
with the renderer in `bevy_pbr`.

This means that, if I am trying to make crate that replaces `bevy_pbr`,
I need to make sure I manually fix this unfinished setup the same way
that `bevy_pbr` does. Worse, it means that if I try to use the
`PrepassNode` `bevy_core_pipeline` adds *without* fixing this, the
engine will simply crash because the `DrawFunctions<T>` resources cannot
be accessed.

The only advantage I can think of for bevy doing it this way is an
ambiguous performance save due to the prepass render phases not being
present unless you are using prepass materials with PBR.

## Solution

I have moved the registration of `DrawFunctions<T>`,
`sort_phase_system::<T>`, camera `RenderPhase` extraction, and texture
preparation for prepass's phase items into `bevy_core_pipeline`
alongside the equivalent code that sets up the `Opaque3d`, `AlphaMask3d`
and `Transparent3d` phase items.

Am open to tweaking this to improve the performance impact of prepass
things being around if the app doesn't use them if needed.

I've tested that the `shader_prepass` example still works with this
change.

Fix the logo image in the "ui" UI example (#7894)
# Objective

The AccessKit PR removed the loading of the image logo from the UI
example.
It also added some alt text with `TextStyle::default()` as a child of
the logo image node.

If you give an image node a child, then its size is no longer determined
by the measurefunc that preserves its aspect ratio. Instead, its width
and height are determined by the constraints set on the node and the
size of the contents of the node. In this case, the image node is set to
have a width of 500 with no constraints on its height. So it looks at
its child node to determine what height it should take. Because the
child has `TextStyle::default` it allocates no space for the text, the
height of the image node is set to zero and the logo isn't drawn.

Fixes #8805

## Solution

Load the image, and set min_size and max_size constraints of 500 by 125
pixels.

Add last_changed_tick and added_tick to ComponentTicks (#8803)
# Objective

EntityRef::get_change_ticks mentions that ComponentTicks is useful to
create change detection for your own runtime.

However, ComponentTicks doesn't even expose enough data to create
something that implements DetectChanges. Specifically, we need to be
able to extract the last change tick.

## Solution

We add a method to get the last change tick. We also add a method to get
the added tick.

## Changelog

- Add `last_changed_tick` and `added_tick` to `ComponentTicks`

Rename Command's "write" method to "apply" (#8814)
# Objective

- Fixes #8811 .

## Solution

- Rename "write" method to "apply" in Command trait definition.
- Rename other implementations of command trait throughout bevy's code
base.

---

## Changelog

- Changed: `Command::write` has been changed to `Command::apply`
- Changed: `EntityCommand::write` has been changed to
`EntityCommand::apply`

## Migration Guide

- `Command::write` implementations need to be changed to implement
`Command::apply` instead. This is a mere name change, with no further
actions needed.
- `EntityCommand::write` implementations need to be changed to implement
`EntityCommand::apply` instead. This is a mere name change, with no
further actions needed.

Add iter_many_manual QueryState method (#8772)
# Objective

`QueryState` exposes a `get_manual` and `iter_manual` method. However,
there is now `iter_many_manual`.

`iter_many_manual` is useful when you have a `&World` (eg: the `world`
in a `Scene`) and want to run a query several times on it (eg:
iteratively navigate a hierarchy by calling `iter_many` on `Children`
component).

`iter_many`'s need for a `&mut World` makes the API much less flexible.
The exclusive access pattern requires doing some very funky dance and
excludes a category of algorithms for hierarchy traversal.

## Solution

- Add a `iter_many_manual` method to `QueryState`

### Alternative

My current workaround is to use `get_manual`. However, this doesn't
benefit from the optimizations on `QueryManyIter`.

---

## Changelog

- Add a `iter_many_manual` method to `QueryState`

Add new and map methods to Ref (#8797)
# Objective

`Ref` is a useful way of accessing change detection data.

However, unlike `Mut`, it doesn't expose a constructor or even a way to
go from `Ref<A>` to `Ref<B>`.

Such methods could be useful, for example, to 3rd party crates that want
to expose change detection information in a clean way.

My use case is to map a `Ref<T>` into a `Ref<dyn Reflect>`, and keep
change detection info to avoid running expansive routines.

## Solution

We add the `new` and `map` methods. Since similar methods exist on `Mut`
where they are much more footgunny to use, I judged that it was
acceptable to create such methods.

## Workaround

Currently, it's not possible to create/project `Ref`s. One can define
their own `Ref` and implement `ChangeDetection` on it. One would then
use `ChangeTrackers` to populate the custom `Ref` with tick data.

---

## Changelog

- Added the `Ref::map` and `Ref::new` methods for more ergonomic `Ref`s

Register a few missed reflect components (#8807)
# Objective

-  Some reflect components weren't properly registered.

## Solution

- We register them
- I also sorted the register lines in `Plugin::build` in `bevy_ui`

### Note

How I did I find them:

- I picked up the list of `Component`s from the `Component` trait page
in rustdoc.
- Then I tried to register all of them. Removing the registration when
it doesn't implement `Reflect` to pass compilation.
- Then I added `app.register_type_data::<T, Foo>()`, for all Reflect
components. It panics if `T` is not registered.
- I repeated the last line N times until bevy stopped panicking at
startup

---

## Changelog

- Register the following components: `PrimaryWindow` `Fxaa`
`FogSettings` `NotShadowCaster` `NotShadowReceiver` `CalculatedClip`
`RelativeCursorPosition`

Remove Component derive for AlphaMode (#8804)
`AlphaMode` is not used as a component anywhere in the engine. It
shouldn't implement `Component`. It might mislead users into thinking it
has any effect as a component.

---

## Changelog

- Remove `Component` implementation for `AlphaMode`. It wasn't used by
anything.

## Migration Guide

`AlphaMode` is not a component anymore.

It wasn't used anywhere in the engine. If you were using it as a
component for your own purposes, you should use a newtype instead, as
follow:

```rust
#[derive(Component, Deref)]
struct MyAlphaMode(AlphaMode);
```

Then replace uses of `AlphaMode` with `MyAlphaMode`

- Query<&AlphaMode, …>,

Disable camera on window close (#8802)
# Objective

- When a window is closed, the associated camera keeps rendering even if
the RenderTarget isn't valid anymore.
	- This is essentially just wasting a lot of performance.

## Solution

- Detect the window close event and disable any camera that used the
window has a RenderTarget.

## Notes

It's possible a similar thing could be done for camera that use an image
handle, but I would fix that in a separate PR.

bevy_reflect: implement Reflect for SmolStr (#8771)
# Objective
To upgrade winit's dependency, it's useful to reuse SmolStr, which
replaces/improves the too restrictive Key letter enums.

As Input<Key> is a resource it should implement Reflect through all its
fields.

## Solution

Implement pendants for winit's `TouchpadMagnify` and `TouchpadRotate`
events.

Adjust the `mouse_input_events.rs` example to debug magnify and rotate
events.

Since winit only reports these events on macOS, the Bevy events for
touchpad magnification and rotation are currently only fired on macOS.

Reflect now requires DynamicTypePath. Remove Reflect::get_type_path() (#8764)
Followup to #7184

This makes `Reflect: DynamicTypePath` which allows us to remove
`Reflect::get_type_path`, reducing unnecessary codegen and simplifying
`Reflect` implementations.

Require #[derive(Event)] on all Events (#7086)
# Objective

Be consistent with `Resource`s and `Components` and have `Event` types
be more self-documenting.
Although not susceptible to accidentally using a function instead of a
value due to `Event`s only being initialized by their type, much of the
same reasoning for removing the blanket impl on `Resource` also applies
here.

* Not immediately obvious if a type is intended to be an event
* Prevent invisible conflicts if the same third-party or primitive types
are used as events
* Allows for further extensions (e.g. opt-in warning for missed events)

## Solution

Remove the blanket impl for the `Event` trait. Add a derive macro for
it.

---

## Changelog

- `Event` is no longer implemented for all applicable types. Add the
`#[derive(Event)]` macro for events.

## Migration Guide

* Add the `#[derive(Event)]` macro for events. Third-party types used as
events should be wrapped in a newtype.

bevy_reflect: Disambiguate type bounds in where clauses. (#8761)
# Objective

It was accidentally found that rustc is unable to parse certain
constructs in `where` clauses properly. `bevy_reflect::Reflect`'s habit
of copying and pasting the field types in a type's definition to its
`where` clauses made it very easy to accidentally run into this
behaviour - particularly with the construct
```rust
where
    for<'a> fn(&'a T) -> &'a T: Trait1 + Trait2
```

which was incorrectly parsed as
```rust
where
    for<'a> (fn(&'a T) -> &'a T: Trait1 + Trait2)
            ^                                   ^ incorrect syntax grouping
```

instead of
```rust
where
    (for<'a> fn(&'a T) -> &'a T): Trait1 + Trait2
    ^                          ^ correct syntax grouping
```

Fixes #8759 

## Solution

This commit fixes the issue by inserting explicit parentheses to
disambiguate types from their bound lists.

correctly setup everything in the default run_once runner (#8740)
# Objective

- Fix #8658 
- `without_winit` example panics `thread 'Compute Task Pool (2)'
panicked at 'called `Option::unwrap()` on a `None` value',
crates/bevy_render/src/pipelined_rendering.rs:134:84`

## Solution

- In the default runner method `run_once`, correctly finish the
initialisation of the plugins. `run_once` can't be called twice so it's
ok to do it there

Allow systems using Diagnostics to run in parallel (#8677)
# Objective

I was trying to add some `Diagnostics` to have a better break down of
performance but I noticed that the current implementation uses a
`ResMut` which forces the functions to all run sequentially whereas
before they could run in parallel. This created too great a performance
penalty to be usable.

## Solution

This PR reworks how the diagnostics work with a couple of breaking
changes. The idea is to change how `Diagnostics` works by changing it to
a `SystemParam`. This allows us to hold a `Deferred` buffer of
measurements that can be applied later, avoiding the need for multiple
mutable references to the hashmap. This means we can run systems that
write diagnostic measurements in parallel.

Firstly, we rename the old `Diagnostics` to `DiagnosticsStore`. This
clears up the original name for the new interface while allowing us to
preserve more closely the original API.

Then we create a new `Diagnostics` struct which implements `SystemParam`
and contains a deferred `SystemBuffer`. This can be used very similar to
the old `Diagnostics` for writing new measurements.

```rust
fn system(diagnostics: ResMut<Diagnostics>) { diagnostics.new_measurement(ID, || 10.0)}
// changes to
fn system(mut diagnostics: Diagnostics) { diagnostics.new_measurement(ID, || 10.0)}
``` 
For reading the diagnostics, the user needs to change from `Diagnostics`
to `DiagnosticsStore` but otherwise the function calls are the same.

Finally, we add a new method to the `App` for registering diagnostics.
This replaces the old method of creating a startup system and adding it
manually.

Testing it, this PR does indeed allow Diagnostic systems to be run in
parallel.

## Changelog

- Change `Diagnostics` to implement `SystemParam` which allows
diagnostic systems to run in parallel.

## Migration Guide

- Register `Diagnostic`'s using the new
`app.register_diagnostic(Diagnostic::new(DIAGNOSTIC_ID,
"diagnostic_name", 10));`
- In systems for writing new measurements, change `mut diagnostics:
ResMut<Diagnostics>` to `mut diagnostics: Diagnostics` to allow the
systems to run in parallel.
- In systems for reading measurements, change `diagnostics:
Res<Diagnostics>` to `diagnostics: Res<DiagnosticsStore>`.

reflect: stable type path v2 (#7184)
# Objective

- Introduce a stable alternative to
[`std::any::type_name`](https://doc.rust-lang.org/std/any/fn.type_name.html).
- Rewrite of #5805 with heavy inspiration in design.
- On the path to #5830.
- Part of solving #3327.


## Solution

- Add a `TypePath` trait for static stable type path/name information.
- Add a `TypePath` derive macro.
- Add a `impl_type_path` macro for implementing internal and foreign
types in `bevy_reflect`.

---

## Changelog

- Added `TypePath` trait.
- Added `DynamicTypePath` trait and `get_type_path` method to `Reflect`.
- Added a `TypePath` derive macro.
- Added a `bevy_reflect::impl_type_path` for implementing `TypePath` on
internal and foreign types in `bevy_reflect`.
- Changed `bevy_reflect::utility::(Non)GenericTypeInfoCell` to
`(Non)GenericTypedCell<T>` which allows us to be generic over both
`TypeInfo` and `TypePath`.
- `TypePath` is now a supertrait of `Asset`, `Material` and
`Material2d`.
- `impl_reflect_struct` needs a `#[type_path = "..."]` attribute to be
specified.
- `impl_reflect_value` needs to either specify path starting with a
double colon (`::core::option::Option`) or an `in my_crate::foo`
declaration.
- Added `bevy_reflect_derive::ReflectTypePath`.
- Most uses of `Ident` in `bevy_reflect_derive` changed to use
`ReflectTypePath`.

## Migration Guide

- Implementors of `Asset`, `Material` and `Material2d` now also need to
derive `TypePath`.
- Manual implementors of `Reflect` will need to implement the new
`get_type_path` method.

## Open Questions
- [x] ~This PR currently does not migrate any usages of
`std::any::type_name` to use `bevy_reflect::TypePath` to ease the review
process. Should it?~ Migration will be left to a follow-up PR.
- [ ] This PR adds a lot of `#[derive(TypePath)]` and `T: TypePath` to
satisfy new bounds, mostly when deriving `TypeUuid`. Should we make
`TypePath` a supertrait of `TypeUuid`? [Should we remove `TypeUuid` in
favour of
`TypePath`?](2afbd85532 (r961067892))

Rename apply_system_buffers to apply_deferred (#8726)
# Objective

- `apply_system_buffers` is an unhelpful name: it introduces a new
internal-only concept
- this is particularly rough for beginners as reasoning about how
commands work is a critical stumbling block

## Solution

- rename `apply_system_buffers` to the more descriptive `apply_deferred`
- rename related fields, arguments and methods in the internals fo
bevy_ecs for consistency
- update the docs


## Changelog

`apply_system_buffers` has been renamed to `apply_deferred`, to more
clearly communicate its intent and relation to `Deferred` system
parameters like `Commands`.

## Migration Guide

- `apply_system_buffers` has been renamed to `apply_deferred`
- the `apply_system_buffers` method on the `System` trait has been
renamed to `apply_deferred`
- the `is_apply_system_buffers` function has been replaced by
`is_apply_deferred`
- `Executor::set_apply_final_buffers` is now
`Executor::set_apply_final_deferred`
- `Schedule::apply_system_buffers` is now `Schedule::apply_deferred`
