dd7a21703f Move safe operations out of unsafe blocks in Query (#7851)
# Objective

Several `Query` methods unnecessarily place the call to `Query::update_archetypes` inside of unsafe blocks.

## Solution

Move the method calls out of the unsafe blocks.

# Objective

- Fixes #1800, fixes #6984
- Alternative to #7196
- Ensure feature list is always up to date and that all are documented
- Help discovery of features

## Solution

- Use a template to update the cargo feature list
- Use the comment just above the feature declaration as the description
- Add the checks to CI
- Add the features to the base crate doc

f732172c73 Text2d doesn't recompute text on changes to the text's bounds (#7846)
# Objective

Text2d entity's text needs to be recomputed when their bounds are changed, but it isn't.

# Solution
Change `update_text2d_layout` to query for `Ref<Text2dBounds>` and recompute the text if the bounds have changed.

9e6ad4607f Use correct terminology for a NonSend run condition panic (#7841)
# Objective

There is a panic that occurs when creating a run condition that accesses `NonSend` resources, but it refers to them as 'thread-local' resources instead.

## Solution

Correct the terminology.

998e983bac Add example to show how to use apply_system_buffers (#7793)
# Objective

This PR adds an example that shows how to use `apply_system_buffers` and how to order it with respect to the relevant systems. It also shows how not ordering the systems can lead to unexpected behaviours.

## Solution

Add the example.

107cdc10bc Use a bounded channel in the multithreaded executor (#7829)
# Objective
This is a follow-up to #7745. An unbounded `async_channel`  occasionally allocates whenever it exceeds the capacity of the current buffer in it's internal linked list. This is avoidable.

This also used to be a bounded channel before stageless, which was introduced in #4919.

## Solution
Use a bounded channel to avoid allocations on system completion.

This shouldn't conflict with #7745, as it's impossible for the scheduler to exceed the channel capacity, even if somehow every system completed at the same time.

3d3444b981 impl Reflect for std::collections::HashMap instead of only bevy::utils::HashMap (#7739) (#7782)
# Objective

Implement `Reflect` for `std::collections::HashMap<K, V, S>` as well as `hashbrown::HashMap<K, V, S>` rather than just for `hashbrown::HashMap<K, V, RandomState>`. Fixes #7739.

## Solution

Rather than implementing on `HashMap<K, V>` I instead implemented most of the related traits on `HashMap<K, V, S> where S: BuildHasher + Send + Sync + 'static` and then `FromReflect` also needs the extra bound `S: Default` because it needs to use `with_capacity_and_hasher` so needs to be able to generate a default hasher.

As the API of `hashbrown::HashMap` is identical to `collections::HashMap` making them both work just required creating an `impl_reflect_for_hashmap` macro like the `impl_reflect_for_veclike` above and then applying this to both HashMaps.

---

## Changelog

`std::collections::HashMap` can now be reflected. Also more `State` generics than just `RandomState` can now be reflected for both `hashbrown::HashMap` and `collections::HashMap`

de10dce10d use try_send to replace send.await, unbounded channel should always b… (#7745)
…e sendable, this improves performance

# Objective

- From prev experience, `.await` is not free, also I did a profiling a half year ago, bevy's multithread executor spend lots cycles on ArcWaker.

## Solution

-  this pr replace `sender.send().await` to `sender.try_send()` to cut some future/await cost.

2344b943a2 Fix unsoundnes in insert remove and despawn (#7805)
`EntityMut::move_entity_from_remove` had two soundness bugs:

- When removing the entity from the archetype, the swapped entity had its table row updated to the same as the removed entity's
- When removing the entity from the table, the swapped entity did not have its table row updated

`BundleInsert::insert` had two/three soundness bugs
- When moving an entity to a new archetype from an `insert`, the swapped entity had its table row set to a different entities 
- When moving an entity to a new table from an `insert`, the swapped entity did not have its table row updated 
See added tests for examples that trigger those bugs

`EntityMut::despawn` had two soundness bugs
- When despawning an entity, the swapped entity had its table row set to a different entities even if the table didnt change
- When despawning an entity, the swapped entity did not have its table row updated

be22569db7 EntityMut: rename remove_intersection to remove and remove to take (#7810)
# Objective

- A more intuitive distinction between the two. `remove_intersection` is verbose and unclear.
- `EntityMut::remove` and `Commands::remove` should match.


## Solution

- What the title says.

---

## Migration Guide

Before
```rust
fn clear_children(parent: Entity, world: &mut World) {
    if let Some(children) = world.entity_mut(parent).remove::<Children>() {
        for &child in &children.0 {
            world.entity_mut(child).remove_intersection::<Parent>();
        }
    }
}
```

After
```rust
fn clear_children(parent: Entity, world: &mut World) {
    if let Some(children) = world.entity_mut(parent).take::<Children>() {
        for &child in &children.0 {
            world.entity_mut(child).remove::<Parent>();
        }
    }

e81142611b add common run conditions to bevy_input (#7806)
# Objective

Common run conditions can be very useful for quick and ergonomic changes to when a system runs.
Specifically what I'd like to be able to do is
```rust
use bevy::prelude::*;
use bevy::input::common_conditions::input_toggle_active;

fn main() {
  App::new()
    .add_plugins(DefaultPlugins)
    .add_plugin(
      bevy_inspector_egui::quick::WorldInspectorPlugin::default()
        .run_if(input_toggle_active(true, KeyCode::Escape)
    )
    .run();
}
```

## Solution

- add `bevy_input::common_conditions` module with `input_toggle_active`, `input_pressed`, `input_just_pressed`, `input_just_released`

## Changelog

- added common run conditions for `bevy_input`
- you can now use `.add_system(jump.run_if(input_just_pressed(KeyCode::Space)))`

b8263b55fb Support system.in_schedule() and system.on_startup() (#7790)
# Objective

Support the following syntax for adding systems:

```rust
App::new()
    .add_system(setup.on_startup())
    .add_systems((
        show_menu.in_schedule(OnEnter(GameState::Paused)),
        menu_ssytem.in_set(OnUpdate(GameState::Paused)),
        hide_menu.in_schedule(OnExit(GameState::Paused)),
    ))
```

## Solution

Add the traits `IntoSystemAppConfig{s}`, which provide the extension methods necessary for configuring which schedule a system belongs to. These extension methods return `IntoSystemAppConfig{s}`, which `App::add_system{s}` uses to choose which schedule to add systems to.

---

## Changelog

+ Added the extension methods `in_schedule(label)` and  `on_startup()` for configuring the schedule a system belongs to.

## Future Work

* Replace all uses of `add_startup_system` in the engine.
* Deprecate this method

e4fd25a952 Only execute #define if current scope is accepting lines (#7798)
# Objective

While working on #7784, I noticed that a `#define VAR` in a `.wgsl` file is always effective, even if it its scope is not accepting lines. 

Example:
```c
#define A
#ifndef A
#define B
#endif
```

Currently, `B` will be defined although it shouldn't. This PR fixes that. 

## Solution

Move the branch responsible for `#define` lines into the last else branch, which is only evaluated if the current scope is accepting lines.

1bd7306a3a make bevy_text optional again (#7801)
# Objective

- `bevy_text` used to be "optional". the feature could be disabled, which meant that the systems were not added but `bevy_text` was still compiled because of a hard dependency in `bevy_ui`
- Running something without `bevy_text` enabled and with `bevy_ui` enabled now crashes:
```
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /bevy/crates/bevy_ecs/src/schedule/schedule.rs:1147:34
```
- This is because `bevy_ui` declares some of its systems in ambiguity sets with systems from `bevy_text`, which were not added if `bevy_text` is disabled

## Solution

- Make `bevy_text` completely optional

## Migration Guide

- feature `bevy_text` now completely removes `bevy_text` from the dependencies when not enabled. Enable feature `bevy_text` if you use Bevy to render text

695d30bd54 Clean up marker generics for systems (#7789)
# Objective

While we use `#[doc(hidden)]` to try and hide marker generics from the user, these types reveal themselves in compiler errors, adding visual noise and confusion.

## Solution

Replace the `AlreadyWasSystem` marker generic with `()`, to reduce visual noise in error messages. This also makes it possible to return `impl Condition<()>` from combinators.

For function systems, use their function signature as the marker type. This should drastically improve the legibility of some error messages.  
The `InputMarker` type has been removed, since it is unnecessary.

ee4c8c5ecd Use consistent names for marker generics (#7788)
# Objective

Several places in the ECS use marker generics to avoid overlapping trait implementations, but different places alternately refer to it as `Params` and `Marker`. This is potentially confusing, since it might not be clear that the same pattern is being used. Additionally, users might be misled into thinking that the `Params` type corresponds to the `SystemParam`s of a system.

## Solution

Rename `Params` to `Marker`.

12aadfd4a6 Support raw buffers in AsBindGroup macro (#7701)
# Objective

There was PR that introduced support for storage buffer is `AsBindGroup` macro [#6129](https://github.com/bevyengine/bevy/pull/6129), but it does not give more granular control over storage buffer, it will always copy all the data no matter which part of it was updated. There is also currently another open PR #6669 that tries to achieve exactly that, it is just not up to date and seems abandoned (Sorry if that is not right). In this PR I'm proposing a solution for both of these approaches to co-exist using `#[storage(n, buffer)]` and `#[storage(n)]` to distinguish between the cases.

We could also discuss in this PR if there is a need to extend this support to DynamicBuffers as well.

3ec87e49ca Stageless: prettier cycle reporting (#7463)
Graph theory make head hurty. Closes #7367.

Basically, when we topologically sort the dependency graph, we already find its strongly-connected components (a really [neat algorithm][1]). This PR adds an algorithm that can dissect those into simple cycles, giving us more useful error reports.

test: `system_build_errors::dependency_cycle`
```
schedule has 1 before/after cycle(s):
cycle 1: system set 'A' must run before itself
system set 'A'
 ... which must run before system set 'B'
 ... which must run before system set 'A'
```
```
schedule has 1 before/after cycle(s):
cycle 1: system 'foo' must run before itself
system 'foo'
 ... which must run before system 'bar'
 ... which must run before system 'foo'
```

17d1fa4a8b Add more "common run conditions" (#7579)
Add some more useful common run conditions.

Some of these existed in `iyes_loopless`. I know people used them, and it would be a regression for those users, when they try to migrate to new Bevy stageless, if they are missing.

I also took the opportunity to add a few more new ones.

---

## Changelog

### Added
 - More "common run conditions": on_event, resource change detection, state_changed, any_with_component

c4f0de52eb Add a BackgroundColor component to TextBundle (#7596)
# Objective

`TextBundle` should have a `BackgroundColor` component.

Apart from adding emphasis etc to text, adding a background color to text nodes can be extremely useful for understanding how Bevy aligns, sizes and positions text, and identifying and debugging problems.

It's easy for users to insert the `BackgroundColor` component themselves but not immediately obvious or discoverable that it's possible. A `BackgroundColor` component allows us to add a `with_background_color` helper function to `TextBundle`.

related issue: #5935

## Solution

Add a `BackgroundColor` component to `TextBundle`.

---

## Changelog

* Added a `BackgroundColor` component to `TextBundle`.
* Added a helper method `with_background_color` to `TextBundle`.

## Migration Guide
`TextBundle` now has a `BackgroundColor` component. 

Use `TextBundle`'s `background_color` field or the `with_background_color` method to set a background color for text when spawning a text node, in place of manual insertion of a `BackgroundColor` component.

d3e426e86f Use default schedule consistently in add_state (#7751)
# Objective

When working on #7750 I noticed that `CoreSchedule::Main` was explicitly used to get the schedule for the `OnUpdate` set. This can lead to failures or weird behavior if `add_state` is used with a differently configured `default_schedule_label`, because the other systems are added to the default schedule. This PR fixes that.

## Solution

Use `default_schedule_label` to retrieve a single schedule to which all systems are added.

2a598d3e5a Add Beziers to bevy_math (#7653)
# Objective

- Adds foundational math for Bezier curves, useful for UI/2D/3D animation and smooth paths.

https://user-images.githubusercontent.com/2632925/218883143-e138f994-1795-40da-8c59-21d779666991.mp4

## Solution

- Adds the generic `Bezier` type, and a `Point` trait. The `Point` trait allows us to use control points of any dimension, as long as they support vector math. I've implemented it for `f32`(1D), `Vec2`(2D), and `Vec3`/`Vec3A`(3D).
- Adds `CubicBezierEasing` on top of `Bezier` with the addition of an implementation of cubic Bezier easing, which is a foundational tool for UI animation.
  - This involves solving for $t$ in the parametric Bezier function $B(t)$ using the Newton-Raphson method to find a value with error $\leq$ 1e-7, capped at 8 iterations.
- Added type aliases for common Bezier curves: `CubicBezier2d`, `CubicBezier3d`, `QuadraticBezier2d`, and `QuadraticBezier3d`. These types use `Vec3A` to represent control points, as this was found to have an 80-90% speedup over using `Vec3`.
- Benchmarking shows quadratic/cubic Bezier evaluations $B(t)$ take \~1.8/2.4ns respectively. Easing, which requires an iterative solve takes \~50ns for cubic Beziers. 

---

## Changelog

- Added `CubicBezier2d`, `CubicBezier3d`, `QuadraticBezier2d`, and `QuadraticBezier3d` types with methods for sampling position, velocity, and acceleration. The generic `Bezier` type is also available, and generic over any degree of Bezier curve.
- Added `CubicBezierEasing`, with additional methods to allow for smooth easing animations.

0c98f9a225 Add AND/OR combinators for run conditions (#7605)
# Objective

Fix #7584.

## Solution

Add an abstraction for creating custom system combinators with minimal boilerplate. Use this to implement AND/OR combinators. Use this to simplify the implementation of `PipeSystem`.

## Example

Feel free to bikeshed on the syntax.

I chose the names `and_then`/`or_else` to emphasize the fact that these short-circuit, while I chose method syntax to empasize that the arguments are *not* treated equally.

```rust
app.add_systems((
    my_system.run_if(resource_exists::<R>().and_then(resource_equals(R(0)))),
    our_system.run_if(resource_exists::<R>().or_else(resource_exists::<S>())),
));
```

---

## Todo

- [ ] Decide on a syntax
- [x] Write docs
- [x] Write tests

## Changelog

+ Added the extension methods `.and_then(...)` and `.or_else(...)` to run conditions, which allows combining run conditions with short-circuiting behavior.
+ Added the trait `Combine`, which can be used with the new `CombinatorSystem` to create system combinators with custom behavior.

e2c77fee03 Remove obsolete after(apply_state_transition::<S>) (#7750)
# Objective

- Fixes #7636.

## Solution

`apply_state_transitions::<S>` runs in `CoreSet::StateTransitions` which is already scheduled before `CoreSet::Update`. Therefore explicitly scheduling `OnUpdate` after `apply_state_transitions::<S>` is not necessary.

e1a8123145 Retain :: after >, ) or ] when shortening type names (#7755)
# Objective

While working on #7442 i discovered that `get_short_name` does not work well with sub paths after closing brackets. It currently turns `bevy_asset::assets::Assets<bevy_scene::dynamic_scene::DynamicScene>::asset_event_system` into `Assets<DynamicScene>asset_event_system`. This PR fixes that.

## Solution
- Retain `::` after a closing bracket like `>`, `)` or `]`.
- Add a test for all sub path after closing bracket cases.

ca1802b774 Basic spatial audio (#6028)
# Objective

- Add basic spatial audio support to Bevy
  - this is what rodio supports, so no HRTF, just simple stereo channel manipulation
  - no "built-in" ECS support: `Emitter` and `Listener` should be components that would automatically update the positions

This PR goal is to just expose rodio functionality, made possible with the recent update to rodio 0.16. A proper ECS integration opens a lot more questions, and would probably require an RFC

Also updates rodio and fixes #6122
