97012950f9 Update nalgebra requirement from 0.29.0 to 0.30.0 (#3540)
Updates the requirements on [nalgebra](https://github.com/dimforge/nalgebra) to permit the latest version.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a href="https://github.com/dimforge/nalgebra/blob/dev/CHANGELOG.md">nalgebra's changelog</a>.</em></p>
<blockquote>
<h2>[0.30.0] (02 Jan. 2022)</h2>
<h3>Breaking changes</h3>
<ul>
<li>The <code>Dim</code> trait is now marked as unsafe.</li>
<li>The <code>Matrix::pow</code> and <code>Matrix::pow_mut</code> methods only allow positive integer exponents now. To compute negative
exponents, the user is free to invert the matrix before calling <code>pow</code> with the exponent’s absolute value.</li>
</ul>
<h3>Modified</h3>
<ul>
<li>Use more concise debug impls for matrices and geometric transformation types.</li>
<li>The singular values computed by the SVD are now sorted in increasing order by default. Use <code>SVD::new_unordered</code>
instead to reproduce the older behavior without the sorting overhead.</li>
<li>The <code>UnitDualQuaternion::sclerp</code> method will no longer panic when given two equal rotations.</li>
<li>The <code>Matrix::select_rows</code> and <code>Matrix::select_columns</code> methods no longer require the matrix components to implement
the trait <code>Zero</code>.</li>
<li>The <code>Matrix::pow</code> and <code>Matrix::pow_mut</code> methods will now also work with integer matrices.</li>
</ul>
<h3>Added</h3>
<ul>
<li>Added the conversion trait <code>From&lt;Vec&lt;T&gt;&gt;</code> and method <code>from_vec_storage</code> for <code>RowDVector</code>.</li>
<li>Added implementation of <code>From</code> and <code>Into</code> for converting between <code>nalgebra</code> types and types from
<code>glam 0.18</code>. These can be enabled by enabling the <code>convert-glam018</code> cargo features.</li>
<li>Added the methods <code>Matrix::product</code>, <code>::row_product</code>, <code>::row_product_tr</code>, and <code>::column_product</code> to compute the
product of the components, rows, or columns, of a single matrix or vector.</li>
<li>The <code>Default</code> trait is now implemented for most geometric types: <code>Point</code>, <code>Isometry</code>, <code>Rotation</code>, <code>Similarity</code>,
<code>Transform</code>, <code>UnitComplex</code>, and <code>UnitQuaternion</code>.</li>
<li>Added the <code>Scale</code> geometric type for representing non-uniform scaling.</li>
<li>Added <code>Cholesky::new_with_substitute</code> that will replace diagonal elements by a given constant whenever <code>Cholesky</code>
meets a non-definite-positiveness.</li>
<li>Re-added the conversion from a vector/matrix slice to a static array.</li>
<li>Added the <code>cuda</code> feature that enables the support of <a href="https://github.com/Rust-GPU/Rust-CUDA">rust-cuda</a> for using
<code>nalgebra</code> features with CUDA kernels written in Rust.</li>
<li>Added special-cases implementations for the 2x2 and 3x3 SVDs for better accuracy and performances.</li>
<li>Added the methods <code>Matrix::polar</code>, <code>Matrix::try_polar</code>, and <code>SVD::to_polar</code> to compute the polar decomposition of
a matrix, based on its SVD.</li>
<li><code>nalgebra-sparse</code>: provide constructors for unsorted but otherwise valid data using the CSR format.</li>
<li><code>nalgebra-sparse</code>: added reading MatrixMarked data files to a sparse <code>CooMatrix</code>.</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Fixed a potential unsoundness with <code>matrix.get(i)</code> and <code>matrix.get_mut(i)</code> where <code>i</code>  is an <code>usize</code>, and <code>matrix</code>
is a matrix slice with non-default strides.</li>
<li>Fixed potential unsoundness with <code>vector.perp</code> where <code>vector</code> isn’t actually a 2D vector as expected.</li>
<li>Fixed linkage issue with <code>nalgebra-lapack</code>: the user of <code>nalgebra-lapack</code> no longer have to add
<code>extern crate lapack-src</code> to their <code>main.rs</code>.</li>
<li>Fixed the <code>no-std</code> build of <code>nalgebra-glm</code>.</li>
<li>Fix the <code>pow</code> and <code>pow_mut</code> functions (the result was incorrect for some exponent values).</li>
</ul>
<h2>[0.29.0]</h2>
<h3>Breaking changes</h3>
<ul>
<li>We updated to the version 0.6 of <code>simba</code>. This means that the trait bounds <code>T: na::RealField</code>, <code>na::ComplexField</code>,
<code>na::SimdRealField</code>, <code>na:SimdComplexField</code> no imply that <code>T: Copy</code> (they only imply that <code>T: Clone</code>). This may affect</li>

85b7589388 bevy_gltf: Add support for loading lights (#3506)
# Objective

- Add support for loading lights from glTF 2.0 files

## Solution

- This adds support for the KHR_punctual_lights extension which supports point, directional, and spot lights, though we don't yet support spot lights.
- Inserting light bundles when creating scenes required registering some more light bundle component types.

dc8fefe27f Remove Bytes, FromBytes, Labels, EntityLabels. Document rest of bevy_core and enable warning on missing docs. (#3521)
This PR is part of the issue #3492.

# Objective

 - Clean up dead code in `bevy_core`.
 - Add and update the `bevy_core` documentation to achieve a 100% documentation coverage.
 - Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.

# Solution

 - Remove unused `Bytes`, `FromBytes`, `Labels`, and `EntityLabels` types and associated systems.
 - Made several types private that really only have use as internal types, mostly pertaining to fixed timestep execution.
 - Add and update the bevy_core documentation.
 - Add the #![warn(missing_docs)] lint.

# Open Questions

Should more of the internal states of `FixedTimestep` be public? Seems mostly to be an implementation detail unless someone really needs that fixed timestep state.

3ba711050f do not add plugin ExtractComponentPlugin twice for StandardMaterial (#3502)
# Objective

- After updating #2988, all the examples started crashing with
```
thread 'main' panicked at 'Plugin "bevy_render::render_component::ExtractComponentPlugin<bevy_asset::handle::Handle<bevy_pbr::pbr_material::StandardMaterial>>" was already added', crates/bevy_app/src/app.rs:831:33
```

## Solution

Plugin was added twice:
directly:
1d0d8a3397/crates/bevy_pbr/src/lib.rs (L73)
and through `MaterialPlugin`:
1d0d8a3397/crates/bevy_pbr/src/lib.rs (L72)
1d0d8a3397/crates/bevy_pbr/src/material.rs (L183)

I removed the extra plugin

db68704231 Enable Msaa for webgl by default (#3489)
# Objective

- `Msaa` was disabled in webgl due to a bug in wgpu
- Bug has been fixed (https://github.com/gfx-rs/wgpu/pull/2307) and backported (https://github.com/gfx-rs/wgpu/pull/2327), and updates for [`wgpu-core`](https://crates.io/crates/wgpu-core/0.12.1) and [`wgpu-hal`](https://crates.io/crates/wgpu-hal/0.12.1) have been released

## Solution

- Remove custom config for `Msaa` in webgl
- I also changed two options that were using the arch instead of the `webgl` feature. it shouldn't change much for webgl, but could help if someone wants to target wasm but not webgl2

d07c8a8fa7 Implement ReflectValue serialization for Duration (#3318)
# Objective

Resolves #3277 

Currenty if we try to serialize a scene that contains a `Duration` (which is very common, since `Timer` contains one), we get an error saying:

> Type 'core::time::Duration' does not support ReflectValue serialization


## Solution

Let `Duration` implement `SerializeValue`.

8a8293b266 Renamed Entity::new to Entity::from_raw (#3465)
# Objective

- Rename `Entity::new(id: u32)` to `Entity::from_raw(id: u32)`.
- Add further documentation.
- fixes #3108

## Solution

- Renamed `Entity::new(id: u32)` to `Entity::from_raw(id: u32)`.
- Docs extended.

I derived the examples from the discussion of issue #3108 .

The [first case](https://github.com/bevyengine/bevy/issues/3108#issuecomment-966669781) mentioned in the linked issue is quite obvious but the [second one](https://github.com/bevyengine/bevy/issues/3108#issuecomment-967093902) probably needs further explanation.

06d9384447 Add FromReflect trait to convert dynamic types to concrete types (#1395)
Dynamic types (`DynamicStruct`, `DynamicTupleStruct`, `DynamicTuple`, `DynamicList` and `DynamicMap`) are used when deserializing scenes, but currently they can only be applied to existing concrete types. This leads to issues when trying to spawn non trivial deserialized scene.
For components, the issue is avoided by requiring that reflected components implement ~~`FromResources`~~ `FromWorld` (or `Default`). When spawning, a new concrete type is created that way, and the dynamic type is applied to it. Unfortunately, some components don't have any valid implementation of these traits.
In addition, any `Vec` or `HashMap` inside a component will panic when a dynamic type is pushed into it (for instance, `Text` panics when adding a text section).

To solve this issue, this PR adds the `FromReflect` trait that creates a concrete type from a dynamic type that represent it, derives the trait alongside the `Reflect` trait, drops the ~~`FromResources`~~ `FromWorld` requirement on reflected components, ~~and enables reflection for UI and Text bundles~~. It also adds the requirement that fields ignored with `#[reflect(ignore)]` implement `Default`, since we need to initialize them somehow.

963e2f08a2 Materials and MaterialPlugin (#3428)
This adds "high level" `Material` and `SpecializedMaterial` traits, which can be used with a `MaterialPlugin<T: SpecializedMaterial>`. `MaterialPlugin` automatically registers the appropriate resources, draw functions, and queue systems. The `Material` trait is simpler, and should cover most use cases. `SpecializedMaterial` is like `Material`, but it also requires defining a "specialization key" (see #3031). `Material` has a trivial blanket impl of `SpecializedMaterial`, which allows us to use the same types + functions for both.

This makes defining custom 3d materials much simpler (see the `shader_material` example diff) and ensures consistent behavior across all 3d materials (both built in and custom). I ported the built in `StandardMaterial` to `MaterialPlugin`. There is also a new `MaterialMeshBundle<T: SpecializedMaterial>`, which `PbrBundle` aliases to.

76ec709ede Add Visibility component to UI (#3426)
# Objective

Fixes #3422 

## Solution

Adds the existing `Visibility` component to UI bundles and checks for it in the extract phase of the render app.

The `ComputedVisibility` component was not added. I don't think the UI camera needs frustum culling, but having `RenderLayers` work may be desirable. However I think we would need to change `check_visibility()` to differentiate between 2d, 3d and UI entities.

5d5d7833f0 fix parenting of scenes (#2410)
# Objective

Fix #2406 

Scene parenting was not done completely, leaving the hierarchy maintenance to the standard system. As scene spawning happens in stage `PreUpdate` and hierarchy maintenance in stage `PostUpdate`, this left the scene in an invalid state parent wise for part of a frame

## Solution

Also add/update the `Children` component when spawning the scene.

I kept the `Children` component as a `SmallVec`, it could be moved to an `HashSet` to guarantee uniqueness

79d36e7c28 Prepare crevice for vendored release (#3394)
# Objective

- Our crevice is still called "crevice", which we can't use for a release
- Users would need to use our "crevice" directly to be able to use the derive macro

## Solution

- Rename crevice to bevy_crevice, and crevice-derive to bevy-crevice-derive
- Re-export it from bevy_render, and use it from bevy_render everywhere
- Fix derive macro to work either from bevy_render, from bevy_crevice, or from bevy

## Remaining

- It is currently re-exported as `bevy::render::bevy_crevice`, is it the path we want?
- After a brief suggestion to Cart, I changed the version to follow Bevy version instead of crevice, do we want that?
- Crevice README.md need to be updated
- in the `Cargo.toml`, there are a few things to change. How do we want to change them? How do we keep attributions to original Crevice?
```

c6d4c63f42 enable wasm-bindgen feature on gilrs (#3420)
WIthout the feature, `gilrs` uses `stdweb` instead of `wasm-bindgen` which isn't compatible with the rest of bevy.

Unfortunately, the `stdweb` dependency is still in the dependency tree, it just isn't used (https://gitlab.com/gilrs-project/gilrs/-/issues/101). This will be fixed in `gilrs 0.9` when it releases.

035ec7b763 Implement non-indexed mesh rendering (#3415)
# Objective

Instead of panicking when the `indices` field of a mesh is `None`, actually manage it.

This is just a question of keeping track of the vertex buffer size.

## Notes

* Relying on this change to improve performance on [bevy_debug_lines using the new renderer](https://github.com/Toqozz/bevy_debug_lines/pull/10)
* I'm still new to rendering, my only expertise with wgpu is the learn-wgpu tutorial, likely I'm overlooking something.

081350916c report shader processing errors in RenderPipelineCache (#3289)
### Problem
- shader processing errors are not displayed
- during hot reloading when encountering a shader with errors, the whole app crashes

### Solution
- log `error!`s for shader processing errors 
- when `cfg(debug_assertions)` is enabled (i.e. you're running in `debug` mode), parse shaders before passing them to wgpu. This lets us handle errors early.

6c479649bf enable Webgl2 optimisation in pbr under feature (#3291)
# Objective

- 3d examples fail to run in webgl2 because of unsupported texture formats or texture too large

## Solution

- switch to supported formats if a feature is enabled. I choose a feature instead of a build target to not conflict with a potential webgpu support

Very inspired by 6813b2edc5, and need #3290 to work.

I named the feature `webgl2`, but it's only needed if one want to use PBR in webgl2. Examples using only 2D already work.

004bbe9f04 Use EventWriter for gilrs_system (#3413)
# Objective

- fixes #3397 

## Solution

- Uses EventWriter instead of ResMut<Event> in gilrs_system.rs.

I also renamed the argument from `event` to `events` for consistency. All other instances I could find in the engine of EventWriter use a plural argument name. Happy to undo or modify this change if desired.

c04dfc1174 Add some of the missing methods to TrackedRenderPass (#3401)

- `push_debug_group`
- `pop_debug_group`
- `set_blend_constant`

https://docs.rs/wgpu/0.12.0/wgpu/struct.RenderPass.html

I need `set_push_constants` but started adding the others as I noticed they were also missing. The `draw indirect` family of methods are still missing as are the `timestamp query` methods.

5479047aa2 Added set_cursor_icon(...) to Window (#3395)
# Objective

The window's cursor should be settable without having to implement a custom cursor icon solution. This will especially be helpful when creating user-interfaces that might like to use the cursor to denote some meaning (e.g., _clickable_, _resizable_, etc.).

## Solution

Added a `CursorIcon` enum that maps one-to-one to winit's `CursorIcon` enum, as well as a method to set/get it for the given `Window`.

3443cc77cb Fixes minimization crash because of cluster updates. (#3369)
# Objective
Fixes: #3368

Issue was caused by screen size being: `(0, 0)`.

## Solution
Don't update clusters if the screen size is zero. A better solution might be to not render when minimized, but this works in the meantime.

340957994d Implement the Overflow::Hidden style property for UI (#3296)
# Objective

This PR implements the `overflow` style property in `bevy_ui`. When set to `Overflow::Hidden`, the children of that node are clipped so that overflowing parts are not rendered. This is an important building block for UI widgets.

## Solution

Clipping is done on the CPU so that it does not break batching.

The clip regions update was implemented as a separate system for clarity, but it could be merged with the other UI systems to avoid doing an additional tree traversal. (I don't think it's important until we fix the layout performance issues though).

A scrolling list was added to the `ui_pipelined` example to showcase `Overflow::Hidden`. For the sake of simplicity, it can only be scrolled with a mouse.

## Solution

# Objective And Solution
Add `set_scissor_rect` from wgpu-rs to the `TrackedRenderPass`. wgpu documentation can be found here:
https://docs.rs/wgpu/latest/wgpu/struct.RenderPass.html#method.set_scissor_rect

The reason for adding this is to cull fragments that are outside of the given rect. For my purposes this is extremely useful for UI.

684c821e96 Schedule gilrs system before input systems (#2989)
# Objective

Previously, the gilrs system had no explicit relationship to the input
systems. This could potentially cause it to be scheduled after the
input systems, leading to a one-frame lag in gamepad inputs.

This was a regression introduced in #1606 which removed the `PreEvent` stage

## Solution

This adds an explicit `before` relationship to the gilrs plugin,
ensuring that raw gamepad events will be processed on the same frame
that they are generated.

Currently the `ClearPassNode` is not exported, due to an additional `use ...;` in the core pipeline's `lib.rs`. This seems unintentional, as there already is a public glob import in the file.

This just removes the explicit use. If it actually was intentional to keep the node internal, let me know.

c061ec33c8 bevy_pbr2: Fix clustering for orthographic projections (#3316)
# Objective

PBR lighting was broken in the new renderer when using orthographic projections due to the way the depth slicing works for the clusters. Fix it.

## Solution

- The default orthographic projection near plane is 0.0. The perspective projection depth slicing does a division by the near plane which gives a floating point NaN and the clustering all breaks down.
- Orthographic projections have a linear depth mapping, so it made intuitive sense to me to do depth slicing with a linear mapping too. The alternative I saw was to try to handle the near plane being at 0.0 and using the exponential depth slicing, but that felt like a hack that didn't make sense.
- As such, I have added code that detects whether the projection is orthographic based on `projection[3][3] == 1.0` and then implemented the orthographic mapping case throughout (when computing cluster AABBs, and when mapping a view space position (or light) to a cluster id in both the rust and shader code).

ffecb05a0a Replace old renderer with new renderer (#3312)
This makes the [New Bevy Renderer](#2535) the default (and only) renderer. The new renderer isn't _quite_ ready for the final release yet, but I want as many people as possible to start testing it so we can identify bugs and address feedback prior to release.

The examples are all ported over and operational with a few exceptions:

* I removed a good portion of the examples in the `shader` folder. We still have some work to do in order to make these examples possible / ergonomic / worthwhile: #3120 and "high level shader material plugins" are the big ones. This is a temporary measure.
* Temporarily removed the multiple_windows example: doing this properly in the new renderer will require the upcoming "render targets" changes. Same goes for the render_to_texture example.
* Removed z_sort_debug: entity visibility sort info is no longer available in app logic. we could do this on the "render app" side, but i dont consider it a priority.

25b62f9577 Port bevy_ui to pipelined-rendering (#2653)
# Objective

Port bevy_ui to pipelined-rendering (see #2535 )

## Solution

I did some changes during the port:
- [X] separate color from the texture asset (as suggested [here](https://discord.com/channels/691052431525675048/743663924229963868/874353914525413406))
- [X] ~give the vertex shader a per-instance buffer instead of per-vertex buffer~ (incompatible with batching)

Remaining features to implement to reach parity with the old renderer:
- [x] textures
- [X] TextBundle

I'd also like to add these features, but they need some design discussion:
- [x] batching
- [ ] separate opaque and transparent phases
- [ ] multiple windows
- [ ] texture atlases
- [ ] (maybe) clipping

a2f0fe24e8 Allow String and &String as Id for AssetServer.get_handle(id) (#3280)
# Objective

Make it easier to build and use an asset path with `format!()`. This can be useful for accessing assets in a loop.

Enabled by this PR:
```rust
let monkey_handle = asset_server.get_handle(&format!("models/monkey/Monkey.gltf#Mesh0/Primitive0"));
let monkey_handle = asset_server.get_handle(format!("models/monkey/Monkey.gltf#Mesh0/Primitive0"));
```

Before this PR:
```rust
let monkey_handle = asset_server.get_handle(format!("models/monkey/Monkey.gltf#Mesh0/Primitive0").as_str());
```

It's just a tiny improvement in ergonomics, but i ran into it and was wondering why the function does not accept a `String` and Bevy is all about simplicity/ergonomics, right? 😄😉

Implement `Into<HandleId>` for `String` and `&String`.

- This will help prevent hard-to-trace NaN propagation in user code, by returning `None` instead of `Some(NaN)`.


Depends on https://github.com/bevyengine/bevy/pull/3269 for CI error fix.

a4e85536c1 Fix clippy errors related to IntoIter::new (#3269)
# Objective

Fixes recent pipeline errors:
```

## Solution

- Replaced `IntoIter::new` with `IntoIterator::into_iter`

## Suggestions

For me it looks like two equivalent `Mesh` structs with the same methods. Should we refactor it? Or, they will be different in the near future?

274ace790b Implement iter() for mutable Queries (#2305)
A sample implementation of how to have `iter()` work on mutable queries without breaking aliasing rules.

# Objective

- Fixes #753

## Solution

- Added a ReadOnlyFetch to WorldQuery that is the `&T` version of `&mut T` that is used to specify the return type for read only operations like `iter()`.
- ~~As the comment suggests specifying the bound doesn't work due to restrictions on defining recursive implementations (like `Or`). However bounds on the functions are fine~~ Never mind I misread how `Or` was constructed, bounds now exist.
- Note that the only mutable one has a new `Fetch` for readonly as the `State` has to be the same for any of this to work

1b8453d9a0 Fix path used by macro not considering that we can use a sub-crate (#3178)
# Problem

Let's say I am writting a simple bevy plugin, and I want to depend on `bevy_ecs` crate instead of depending on the full `bevy`. 

So I write the following:

*Cargo.toml*:
```toml
[dependencies]
bevy_ecs = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886" }
```

*lib.rs*:
```rust
use bevy_ecs::prelude::*;

#[derive(Debug, Default, Component)
pub struct MyFancyComponent;
```

So far, so good. Everything works. But let's say I want to write some examples for using my plugin. And for theses I'd like to use the `bevy` crate, so that I can write complete examples (rendering stuff, etc.) that are simple and look like what the consumer of my plugin will do (`use bevy::prelude::*` and `DefaultPlugins`)

So I amend my *Cargo.toml*:
```toml
[dependencies]
bevy_ecs = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886" }

[dev-dependencies]
bevy = { git = "https://github.com/bevyengine/bevy.git", rev = "94db0176fecfac7e7e9763f2dc7458a54c105886", default-features = false }
```

And that  leads to a complilation error 

```
error[E0433]: failed to resolve: use of undeclared crate or module `bevy`
```

Basically, because `bevy` is in the `dev-dependencies`, the macro (of the production code) decides to use the `bevy::ecs` path instead of `bevy_ecs`. But `bevy` is not available there.

## Solution

This PR fixes the problem. I amend the macro utility responsible of finding the path of a module.

If we try to find a path, we first test if this correspond to a crate that the user directly depend on. (Like, if we search for `bevy_ecs`, we first check if there is a `bevy_ecs` dependency). If yes, we can depend on that directly. Otherwise, we proceed with the existing logic (testing `bevy` and `bevy_internal`)

2e79951659 Shader Imports. Decouple Mesh logic from PBR (#3137)
## Shader Imports

This adds "whole file" shader imports. These come in two flavors:

### Asset Path Imports

```rust
// /assets/shaders/custom.wgsl

#import "shaders/custom_material.wgsl"

[[stage(fragment)]]
fn fragment() -> [[location(0)]] vec4<f32> {
    return get_color();
}
```

```rust
// /assets/shaders/custom_material.wgsl

[[block]]
struct CustomMaterial {
    color: vec4<f32>;
};
[[group(1), binding(0)]]
var<uniform> material: CustomMaterial;
```

### Custom Path Imports

Enables defining custom import paths. These are intended to be used by crates to export shader functionality:

```rust
// bevy_pbr2/src/render/pbr.wgsl

#import bevy_pbr::mesh_view_bind_group
#import bevy_pbr::mesh_bind_group

[[block]]
struct StandardMaterial {
    base_color: vec4<f32>;
    emissive: vec4<f32>;
    perceptual_roughness: f32;
    metallic: f32;
    reflectance: f32;
    flags: u32;
};

/* rest of PBR fragment shader here */
```

```rust
impl Plugin for MeshRenderPlugin {
    fn build(&self, app: &mut bevy_app::App) {
        let mut shaders = app.world.get_resource_mut::<Assets<Shader>>().unwrap();
        shaders.set_untracked(
            MESH_BIND_GROUP_HANDLE,
            Shader::from_wgsl(include_str!("mesh_bind_group.wgsl"))
                .with_import_path("bevy_pbr::mesh_bind_group"),
        );
        shaders.set_untracked(
            MESH_VIEW_BIND_GROUP_HANDLE,
            Shader::from_wgsl(include_str!("mesh_view_bind_group.wgsl"))
                .with_import_path("bevy_pbr::mesh_view_bind_group"),
        );
```

By convention these should use rust-style module paths that start with the crate name. Ultimately we might enforce this convention.

Note that this feature implements _run time_ import resolution. Ultimately we should move the import logic into an asset preprocessor once Bevy gets support for that.

## Decouple Mesh Logic from PBR Logic via MeshRenderPlugin

This breaks out mesh rendering code from PBR material code, which improves the legibility of the code, decouples mesh logic from PBR logic, and opens the door for a future `MaterialPlugin<T: Material>` that handles all of the pipeline setup for arbitrary shader materials.

## Removed `RenderAsset<Shader>` in favor of extracting shaders into RenderPipelineCache

This simplifies the shader import implementation and removes the need to pass around `RenderAssets<Shader>`.

##  RenderCommands are now fallible

This allows us to cleanly handle pipelines+shaders not being ready yet. We can abort a render command early in these cases, preventing bevy from trying to bind group / do draw calls for pipelines that couldn't be bound. This could also be used in the future for things like "components not existing on entities yet". 

# Next Steps

* Investigate using Naga for "partial typed imports" (ex: `#import bevy_pbr::material::StandardMaterial`, which would import only the StandardMaterial struct)
* Implement `MaterialPlugin<T: Material>` for low-boilerplate custom material shaders
* Move shader import logic into the asset preprocessor once bevy gets support for that.

d0f423d653 Assert compiler errors for compile_fail tests (#3067)
# Objective

bevy_ecs has several compile_fail tests that assert lifetime safety. In the past, these tests have been green for the wrong reasons (see e.g. #2984). This PR makes sure, that they will fail if the compiler error changes.

## Solution

Use [trybuild](https://crates.io/crates/trybuild) to assert the compiler errors.

The UI tests are in a separate crate that is not part of the Bevy workspace. This is to ensure that they do not break Bevy's crater builds. The tests get executed by the CI workflow on the stable toolchain.

> Buffer data **MAY** alternatively be embedded in the glTF file via `data:` URI with base64 encoding. When `data:` URI is used for buffer storage, its mediatype field **MUST** be set to `application/octet-stream` or `application/gltf-buffer`.

b3cd48228b add detailed errors (#2994)

## Solution

- Start something like https://github.com/rust-lang/rust/tree/master/compiler/rustc_error_codes/src/error_codes
- Remove sentence about Rust mutability rules which is not very helpful in the error message

I decided to start the error code with B for Bevy so that they're not confused with error code from rust (which starts with E)


Longer term, there are a few more evolutions that can continue this:
- the code samples should be compiled check, and even executed for some of them to check they have the correct error code in a panic
- the error could be build on a page in the website like https://doc.rust-lang.org/error-index.html
- most panic should have their own error code

f4776f2ec4 Add entity ID to expect() message (#2943)
Add the entity ID and generation to the expect() message of two
world accessors, to make it easier to debug use-after-free issues.
Coupled with e.g. bevy-inspector-egui which also displays the entity ID,
this makes it much easier to identify what entity is being misused.

# Objective

Make it easier to identity an entity being accessed after being deleted.

## Solution

Augment the error message of some `expect()` call with the entity ID and
generation. Combined with some external tool like `bevy-inspector-egui`, which
also displays the entity ID, this increases the chances to be able to identify
the entity, and therefore find the error that led to a use-after-despawn.

0887f41b58 Fix bevy_ecs::schedule::executor_parallel::system span management (#2905)
# Objective

- Fixes #2904 (see for context)

## Solution

- Simply hoist span creation out of the threaded task
- Confirmed to solve the issue locally

Now all events have the full span parent tree up through `bevy_ecs::schedule::stage` all the way to `bevy_app::app::bevy_app` (and its parents in bevy-consumer code, if any).

a60fe30ada Avoid some format! into immediate format! (#2913)
# Objective

- Avoid usages of `format!` that ~immediately get passed to another `format!`. This avoids a temporary allocation and is just generally cleaner.

## Solution

- `bevy_derive::shader_defs` does a `format!("{}", val.to_string())`, which is better written as just `format!("{}", val)`
- `bevy_diagnostic::log_diagnostics_plugin` does a `format!("{:>}", format!(...))`, which is better written as `format!("{:>}", format_args!(...))`
- `bevy_ecs::schedule` does `tracing::info!(..., name = &*format!("{:?}", val))`, which is better written with the tracing shorthand `tracing::info!(..., name = ?val)`
- `bevy_reflect::reflect` does `f.write_str(&format!(...))`, which is better written as `write!(f, ...)` (this could also be written using `f.debug_tuple`, but I opted to maintain alt debug behavior)
- `bevy_reflect::serde::{ser, de}` do `serde::Error::custom(format!(...))`, which is better written as `Error::custom(format_args!(...))`, as `Error::custom` takes `impl Display` and just immediately calls `format!` again

07ed1d053e Implement and require #[derive(Component)] on all component structs (#2254)
This implements the most minimal variant of #1843 - a derive for marker trait. This is a prerequisite to more complicated features like statically defined storage type or opt-out component reflection.

In order to make component struct's purpose explicit and avoid misuse, it must be annotated with `#[derive(Component)]` (manual impl is discouraged for compatibility). Right now this is just a marker trait, but in the future it might be expanded. Making this change early allows us to make further changes later without breaking backward compatibility for derive macro users.

This already prevents a lot of issues, like using bundles in `insert` calls. Primitive types are no longer valid components as well. This can be easily worked around by adding newtype wrappers and deriving `Component` for them.

One funny example of prevented bad code (from our own tests) is when an newtype struct or enum variant is used. Previously, it was possible to write `insert(Newtype)` instead of `insert(Newtype(value))`. That code compiled, because function pointers (in this case newtype struct constructor) implement `Send + Sync + 'static`, so we allowed them to be used as components. This is no longer the case and such invalid code will trigger a compile error.

5ba2b9adcf Unique WorldId (#2827)
# Objective

Fixes these issues:
- `WorldId`s currently aren't necessarily unique
    - I want to guarantee that they're unique to safeguard my librarified version of https://github.com/bevyengine/bevy/discussions/2805
    - There probably hasn't been a collision yet, but they could technically collide
- `SystemId` isn't used for anything
  - It's no longer used now that `Locals` are stored within the `System`.
- `bevy_ecs` depends on rand

## Solution

- Instead of randomly generating `WorldId`s, just use an incrementing atomic counter, panicing on overflow.
- Remove `SystemId` 
    - We do need to allow Locals for exclusive systems at some point, but exclusive systems couldn't access their own `SystemId` anyway.
- Now that these don't depend on rand, move it to a dev-dependency

## Todo

Determine if `WorldId` should be `u32` based instead

99199338ad add_texture returns index to texture (#2864)
If you need to build a texture atlas from an already created texture that is not match a grid, you need to use new_empty and add_texture to create it.  However it is not straight forward to get the index to be used with TextureAtlasSprite. add_texture should be changed to return the index to the texture.

Currently you can do something like this:

```rs
let texture = asset_server.load::<Texture>::("texture.png");
let texture_atlas = TextureAtlas::new_empty(texture, Vec2::new(40.0, 40.0));

texture_atlas.add_texture(Rect { 
  min: Vec2::new(20.0, 20.0),
  max: Vec2::new(40.0, 40.0),
});
let index = (texture_atlas.len() - 1) as u32;

let texture_atlas_sprite = TextureAtlasSprite {
  index,
  Default::default()
};
```

But this is more clear
```rs
let index = texture_atlas.add_texture(Rect { 
  min: Vec2::new(20.0, 20.0),
  max: Vec2::new(40.0, 40.0),
});
```

08969a24b8 Modular Rendering (#2831)
This changes how render logic is composed to make it much more modular. Previously, all extraction logic was centralized for a given "type" of rendered thing. For example, we extracted meshes into a vector of ExtractedMesh, which contained the mesh and material asset handles, the transform, etc. We looked up bindings for "drawn things" using their index in the `Vec<ExtractedMesh>`. This worked fine for built in rendering, but made it hard to reuse logic for "custom" rendering. It also prevented us from reusing things like "extracted transforms" across contexts.

To make rendering more modular, I made a number of changes:

* Entities now drive rendering:
  * We extract "render components" from "app components" and store them _on_ entities. No more centralized uber lists! We now have true "ECS-driven rendering"
  * To make this perform well, I implemented #2673 in upstream Bevy for fast batch insertions into specific entities. This was merged into the `pipelined-rendering` branch here: #2815
* Reworked the `Draw` abstraction:
  * Generic `PhaseItems`: each draw phase can define its own type of "rendered thing", which can define its own "sort key"
  * Ported the 2d, 3d, and shadow phases to the new PhaseItem impl (currently Transparent2d, Transparent3d, and Shadow PhaseItems)
  * `Draw` trait and and `DrawFunctions` are now generic on PhaseItem
  * Modular / Ergonomic `DrawFunctions` via `RenderCommands`
    * RenderCommand is a trait that runs an ECS query and produces one or more RenderPass calls. Types implementing this trait can be composed to create a final DrawFunction. For example the DrawPbr DrawFunction is created from the following DrawCommand tuple. Const generics are used to set specific bind group locations:
        ```rust
         pub type DrawPbr = (
            SetPbrPipeline,
            SetMeshViewBindGroup<0>,
            SetStandardMaterialBindGroup<1>,
            SetTransformBindGroup<2>,
            DrawMesh,
        );
        ```
    * The new `custom_shader_pipelined` example illustrates how the commands above can be reused to create a custom draw function:
       ```rust
       type DrawCustom = (
           SetCustomMaterialPipeline,
           SetMeshViewBindGroup<0>,
           SetTransformBindGroup<2>,
           DrawMesh,
       );
       ``` 
* ExtractComponentPlugin and UniformComponentPlugin:
  * Simple, standardized ways to easily extract individual components and write them to GPU buffers
* Ported PBR and Sprite rendering to the new primitives above.
* Removed staging buffer from UniformVec in favor of direct Queue usage
  * Makes UniformVec much easier to use and more ergonomic. Completely removes the need for custom render graph nodes in these contexts (see the PbrNode and view Node removals and the much simpler call patterns in the relevant Prepare systems).
* Added a many_cubes_pipelined example to benchmark baseline 3d rendering performance and ensure there were no major regressions during this port. Avoiding regressions was challenging given that the old approach of extracting into centralized vectors is basically the "optimal" approach. However thanks to a various ECS optimizations and render logic rephrasing, we pretty much break even on this benchmark!
* Lifetimeless SystemParams: this will be a bit divisive, but as we continue to embrace "trait driven systems" (ex: ExtractComponentPlugin, UniformComponentPlugin, DrawCommand), the ergonomics of `(Query<'static, 'static, (&'static A, &'static B, &'static)>, Res<'static, C>)` were getting very hard to bear. As a compromise, I added "static type aliases" for the relevant SystemParams. The previous example can now be expressed like this: `(SQuery<(Read<A>, Read<B>)>, SRes<C>)`. If anyone has better ideas / conflicting opinions, please let me know!
* RunSystem trait: a way to define Systems via a trait with a SystemParam associated type. This is used to implement the various plugins mentioned above. I also added SystemParamItem and QueryItem type aliases to make "trait stye" ecs interactions nicer on the eyes (and fingers).
* RenderAsset retrying: ensures that render assets are only created when they are "ready" and allows us to create bind groups directly inside render assets (which significantly simplified the StandardMaterial code). I think ultimately we should swap this out on "asset dependency" events to wait for dependencies to load, but this will require significant asset system changes.
* Updated some built in shaders to account for missing MeshUniform fields

615d43b998 Improve bevy_ecs and bevy_app API docs where referenced by the new Bevy Book (#2365)
## Objective

The upcoming Bevy Book makes many references to the API documentation of bevy.

Most references belong to the first two chapters of the Bevy Book:

- bevyengine/bevy-website#176
- bevyengine/bevy-website#182

This PR attempts to improve the documentation of `bevy_ecs` and `bevy_app` in order to help readers of the Book who want to delve deeper into technical details.

## Solution

- Add crate and level module documentation
- Document the most important items (basically those included in the preludes), with the following style, where applicable:
    - **Summary.** Short description of the item.
    - **Second paragraph.** Detailed description of the item, without going too much in the implementation.
    - **Code example(s).**
    - **Safety or panic notes.**

## Collaboration

Any kind of collaboration is welcome, especially corrections, wording, new ideas and guidelines on where the focus should be put in.

064af63400 Add trace_tracy feature for Tracy profiling (#2832)
# Objective

[Tracy](https://github.com/wolfpld/tracy) is:
> A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler for games and other applications.

With the `trace_tracy` feature enabled, you run your bevy app and either a headless server (`capture`) or a live, interactive profiler UI (`Tracy`), and connect that to your bevy application to then stream the metric data and events, and save it or inspect it live/offline.

Previously when I implemented the spans across systems and stages and I was trying out different profiling tools, Tracy was too unstable on macOS to use. But now, quite some months later, it is working stably with Tracy 0.7.8. You can see timelines, aggregate statistics of mean system/stage execution times, and much more. It's very useful!

![Screenshot_2021-09-15_at_18 07 19](https://user-images.githubusercontent.com/302146/133554920-350d3d45-fbb8-479f-91f7-7a7a4f9f5873.png)

## Solution

- Use the `tracing-tracy` crate which supports our tracing spans
- Expose via the non-default feature `trace_tracy` for consistency with other `trace*` features

11b41206eb Add upstream bevy_ecs and prepare for custom-shaders merge (#2815)
This updates the `pipelined-rendering` branch to use the latest `bevy_ecs` from `main`. This accomplishes a couple of goals:

1. prepares for upcoming `custom-shaders` branch changes, which were what drove many of the recent bevy_ecs changes on `main`
2. prepares for the soon-to-happen merge of `pipelined-rendering` into `main`. By including bevy_ecs changes now, we make that merge simpler / easier to review. 

I split this up into 3 commits:

1. **add upstream bevy_ecs**: please don't bother reviewing this content. it has already received thorough review on `main` and is a literal copy/paste of the relevant folders (the old folders were deleted so the directories are literally exactly the same as `main`).
2. **support manual buffer application in stages**: this is used to enable the Extract step. we've already reviewed this once on the `pipelined-rendering` branch, but its worth looking at one more time in the new context of (1).
3. **support manual archetype updates in QueryState**: same situation as (2).

51a5070cd2 add get_single variant (#2793)
# Objective

The vast majority of `.single()` usage I've seen is immediately followed by a `.unwrap()`. Since it seems most people use it without handling the error, I think making it easier to just get what you want fast while also having a more verbose alternative when you want to handle the error could help.

## Solution

Instead of having a lot of `.unwrap()` everywhere, this PR introduces a `try_single()` variant that behaves like the current `.single()` and make the new `.single()` panic on error.

2f6c464f4b Add builder methods to Transform (#2778)
# Objective

Make it easier to construct transforms. E.g.

```rs
Transform::from_xyz(0.0, 0.0, 10.0).with_scale(Vec3::splat(2.0))
```

I found myself writing an extension method to do this so I don't have to write:

```rs
Transform {
  translation: Vec3::new(0.0, 0.0, 10.0),
  scale: Vec3::splat(2.0),
  ..Default::default()
}
```

## Solution

Add *builder style* methods to `Transform`.

Methods:

- `with_translation`
- `with_rotation`
- `with_scale`

I also added these methods to `GlobalTransform`. But they are probably less useful there.

321d998615 Add convenience methods for checking a set of inputs (#2760)
# Objective

Make it easier to check if some set of inputs matches a key, such as if you want to allow all of space or up or w for jumping.

Currently, this requires:
```rust
if keyboard.pressed(KeyCode::Space)
            || keyboard.pressed(KeyCode::Up)
            || keyboard.pressed(KeyCode::W) {
    // ...
```

## Solution

Add an implementation of the helper methods, which very simply iterate through the items, used as:
```rust
if keyboard.any_pressed([KeyCode::Space, KeyCode::Up, KeyCode::W]) {
```

af20cad830 Add error messages for the spooky insertions (#2581)
# Objective

Sometimes, the unwraps in `entity_mut` could fail here, if the entity was despawned *before* this command was applied.

The simplest case involves two command buffers:
```rust
use bevy::prelude::*;
fn b(mut commands1: Commands, mut commands2: Commands) {
    let id = commands2.spawn().insert_bundle(()).id();
    commands1.entity(id).despawn();
}
fn main() {
    App::build().add_system(b.system()).run();
}
```

However, a more complicated version arises in the case of ambiguity:

```rust
use std::time::Duration;

use bevy::{app::ScheduleRunnerPlugin, prelude::*};
use rand::Rng;

fn cleanup(mut e: ResMut<Option<Entity>>) {
    *e = None;
}

fn sleep_randomly() {
    let mut rng = rand::thread_rng();
    std:🧵:sleep(Duration::from_millis(rng.gen_range(0..50)));
}

fn spawn(mut commands: Commands, mut e: ResMut<Option<Entity>>) {
    *e = Some(commands.spawn().insert_bundle(()).id());
}

fn despawn(mut commands: Commands, e: Res<Option<Entity>>) {
    let mut rng = rand::thread_rng();
    std:🧵:sleep(Duration::from_millis(rng.gen_range(0..50)));
    if let Some(e) = *e {
        commands.entity(e).despawn();
    }
}

fn main() {
    App::build()
        .add_system(cleanup.system().label("cleanup"))
        .add_system(sleep_randomly.system().label("before_despawn"))
        .add_system(despawn.system().after("cleanup").after("before_despawn"))
        .add_system(sleep_randomly.system().label("before_spawn"))
        .add_system(spawn.system().after("cleanup").after("before_spawn"))
        .insert_resource(None::<Entity>)
        .add_plugin(ScheduleRunnerPlugin::default())
        .run();
}
```

In the cases where this example crashes, it's because `despawn` was ordered before `spawn` in the topological ordering of systems (which determines when buffers are applied). However, `despawn` actually ran *after* `spawn`, because these systems are ambiguous, so the jiggles in the sleeping time triggered a case where this works.

## Solution

- Give a better error message

dea292d199 Derive thiserror::Error for HexColorError (#2740)
# Objective

- Make it easy to use HexColorError with `thiserror`, i.e. converting it into other error types.

Makes this possible:

```rust
#[derive(Debug, thiserror::Error)]
pub enum LdtkError {
    #[error("An error occured while deserializing")]
    Json(#[from] serde_json::Error),
    #[error("An error occured while parsing a color")]
    HexColor(#[from] bevy::render::color::HexColorError),
}
```

## Solution

- Derive thiserror::Error the same way we do elsewhere (see query.rs for instance)

b47217bfab Spawn specific entities: spawn or insert operations, refactor spawn internals, world clearing (#2673)
This upstreams the code changes used by the new renderer to enable cross-app Entity reuse:

* Spawning at specific entities
* get_or_spawn: spawns an entity if it doesn't already exist and returns an EntityMut
* insert_or_spawn_batch: the batched equivalent to `world.get_or_spawn(entity).insert_bundle(bundle)`
* Clearing entities and storages
* Allocating Entities with "invalid" archetypes. These entities cannot be queried / are treated as "non existent". They serve as "reserved" entities that won't show up when calling `spawn()`. They must be "specifically spawned at" using apis like `get_or_spawn(entity)`.

In combination, these changes enable the "render world" to clear entities / storages each frame and reserve all "app world entities". These can then be spawned during the "render extract step".

This refactors "spawn" and "insert" code in a way that I think is a massive improvement to legibility and re-usability. It also yields marginal performance wins by reducing some duplicate lookups (less than a percentage point improvement on insertion benchmarks). There is also some potential for future unsafe reduction (by making BatchSpawner and BatchInserter generic). But for now I want to cut down generic usage to a minimum to encourage smaller binaries and faster compiles.

This is currently a draft because it needs more tests (although this code has already had some real-world testing on my custom-shaders branch). 

I also fixed the benchmarks (which currently don't compile!) / added new ones to illustrate batching wins.

After these changes, Bevy ECS is basically ready to accommodate the new renderer. I think the biggest missing piece at this point is "sub apps".

481fa3c7a0 derive Debug, Clone for FixedState (StableAHash) (#2694)
This matches `ahash::RandomState`, which provides both `Debug` and `Clone`.

Notably, implementing `Clone` allows the `StableHashMap`/`Set` to also implement `Clone`.

# Objective

- Allow `bevy_utils::StableHashMap` to be cloned.

## Solution

- Derive `Clone` for `bevy_utils::FixedState`.
- Also derive `Debug`, since we're touching it anyway, and this aligns `FixedState` with `ahash::RandomState`.

e290a7e29c Implement Sub-App Labels (#2695)
This is a rather simple but wide change, and it involves adding a new `bevy_app_macros` crate. Let me know if there is a better way to do any of this!

---

# Objective

- Allow adding and accessing sub-apps by using a label instead of an index

## Solution

- Migrate the bevy label implementation and derive code to the `bevy_utils` and `bevy_macro_utils` crates and then add a new `SubAppLabel` trait to the `bevy_app` crate that is used when adding or getting a sub-app from an app.

98a08cf495 feat: remove_component for ReflectComponent (#2682)
# Objective

While implementing a plugin for my rollback networking library, I needed to load/save parts of the world. For this, I made a WorldSnapshot that works quite like the current DynamicScene. Using a TypeRegistry to register component types I want to save/load and then using ReflectComponents methods to add or apply components of the given types. 

However, I noticed there is no method to remove components from entities through the ReflectComponent.

## Solution

I added a `remove_component` field to the `ReflectComponent` struct, as well as a `pub fn remove_component(&self, world: &mut World, entity: Entity)` to call that function in `remove_component`. This follows exactly the same pattern all other methods/fields in this struct look like.

This is an example how it could be used (at least how I would use it):

9d453530fa System Param Lifetime Split (#2605)
# Objective

Enable using exact World lifetimes during read-only access . This is motivated by the new renderer's need to allow read-only world-only queries to outlive the query itself (but still be constrained by the world lifetime).

For example:
115b170d1f/pipelined/bevy_pbr2/src/render/mod.rs (L774)

## Solution

Split out SystemParam state and world lifetimes and pipe those lifetimes up to read-only Query ops (and add into_inner for Res). According to every safety test I've run so far (except one), this is safe (see the temporary safety test commit). Note that changing the mutable variants to the new lifetimes would allow aliased mutable pointers (try doing that to see how it affects the temporary safety tests).

The new state lifetime on SystemParam does make `#[derive(SystemParam)]` more cumbersome (the current impl requires PhantomData if you don't use both lifetimes). We can make this better by detecting whether or not a lifetime is used in the derive and adjusting accordingly, but that should probably be done in its own pr.  

## Why is this a draft?

The new lifetimes break QuerySet safety in one very specific case (see the query_set system in system_safety_test). We need to solve this before we can use the lifetimes given.

This is due to the fact that QuerySet is just a wrapper over Query, which now relies on world lifetimes instead of `&self` lifetimes to prevent aliasing (but in systems, each Query has its own implied lifetime, not a centralized world lifetime).  I believe the fix is to rewrite QuerySet to have its own World lifetime (and own the internal reference). This will complicate the impl a bit, but I think it is doable. I'm curious if anyone else has better ideas.

Personally, I think these new lifetimes need to happen. We've gotta have a way to directly tie read-only World queries to the World lifetime. The new renderer is the first place this has come up, but I doubt it will be the last. Worst case scenario we can come up with a second `WorldLifetimeQuery<Q, F = ()>` parameter to enable these read-only scenarios, but I'd rather not add another type to the type zoo.

d59fc076e8 Comprehensive CONTRIBUTING.md (#2040)
[**RENDERED**](https://github.com/alice-i-cecile/bevy/blob/better-contributing/CONTRIBUTING.md)

Improves #910. As discussed in #1309, we'll need to synchronize content between this and the Bevy website in some way (and clean up the .github file perhaps?).

I think doing it as a root-directory file is nicer for discovery, but that's a conversation I'm interested in having.

This document is intended to be helpful to beginners to open source and Bevy, and captures what I've learned about our informal practices and values.

Reviewers: I'm particularly interested in:
- opinions on the items **What we're trying to build**, where I discuss some of the project's high-level values and goals
- more relevant details on the `bevy` subcrates for **Getting oriented**
- useful tricks and best practices that I missed
- better guidance on how to contribute to the Bevy book from @cart <3

96f0e02728 Implement Clone for Fetches (#2641)
# Objective

This:

```rust
use bevy::prelude::*;

fn main() {
    App::new()
    .add_system(test)
    .run();
}

fn test(entities: Query<Entity>) {
    let mut combinations = entities.iter_combinations_mut();
    while let Some([e1, e2]) = combinations.fetch_next() {    
        dbg!(e1);
    }
}
```

fails with the message "the trait bound `bevy::ecs::query::EntityFetch: std::clone::Clone` is not satisfied". 


## Solution

It works after adding the naive clone implementation to EntityFetch. I'm not super familiar with ECS internals, so I'd appreciate input on this.

- With the proposed change you can do this:
```rust
App::build()
    .add_plugin(bevy::core::CorePlugin)
    .add_plugin(bevy::app::ScheduleRunnerPlugin)
```

## Solution

- Change the `ScheduleRunnerPlugin` definition to use a semicolon instead of curly braces.

336583a86b Update EntityMut's location in push_children() and insert_children() (#2604)
## Objective

This code would result in a crash:
```rust
use bevy::prelude::*;

fn main() {
    let mut world = World::new();
    let child = world.spawn().id();
    world.spawn().push_children(&[child]);
}
```

## Solution

Update the `EntityMut`'s location after inserting a component on the children entities, as it may have changed.

# Objective

Port bevy_gltf to the pipelined-rendering branch.

## Solution

crates/bevy_gltf has been copied and pasted into pipelined/bevy_gltf2 and modifications were made to work with the pipelined-rendering branch. Notably vertex tangents and vertex colours are not supported.

# Objective

notify 5.0.0-pre.11 breaks the interface again, but apparently in a way that's similar to how it used to be

## Solution

Bump `bevy_asset` dependency on notify to `5.0.0-pre.11` and fix the errors that crop up.

It looks like `pre.11` was mentioned in #2528 by @mockersf but there's no mention of why `pre.10` was chosen ultimately.

86cc70b902 Refactor ECS to reduce the dependency on a 1-to-1 mapping between components and real rust types (#2490)
# Objective

There is currently a 1-to-1 mapping between components and real rust types. This means that it is impossible for multiple components to be represented by the same rust type or for a component to not have a rust type at all. This means that component types can't be defined in languages other than rust like necessary for scripting or sandboxed (wasm?) plugins.

## Solution

Refactor `ComponentDescriptor` and `Bundle` to remove `TypeInfo`. `Bundle` now uses `ComponentId` instead. `ComponentDescriptor` is now always created from a rust type instead of through the `TypeInfo` indirection. A future PR may make it possible to construct a `ComponentDescriptor` from it's fields without a rust type being involved.

b1a91a823f bevy_pbr2: Add support for most of the StandardMaterial textures (#4)
* bevy_pbr2: Add support for most of the StandardMaterial textures

Normal maps are not included here as they require tangents in a vertex attribute.

* bevy_pbr2: Ensure RenderCommandQueue is ready for PbrShaders init

* texture_pipelined: Add a light to the scene so we can see stuff

* WIP bevy_pbr2: back to front sorting hack

* bevy_pbr2: Uniform control flow for texture sampling in pbr.frag

From 'fintelia' on the Bevy Render Rework Round 2 discussion:

"My understanding is that GPUs these days never use the "execute both branches
and select the result" strategy. Rather, what they do is evaluate the branch
condition on all threads of a warp, and jump over it if all of them evaluate to
false. If even a single thread needs to execute the if statement body, however,
then the remaining threads are paused until that is completed."

* bevy_pbr2: Simplify texture and sampler names

The StandardMaterial_ prefix is no longer needed

* bevy_pbr2: Match default 'AmbientColor' of current bevy_pbr for now

* bevy_pbr2: Convert from non-linear to linear sRGB for the color uniform

* bevy_pbr2: Add pbr_pipelined example

* Fix view vector in pbr frag to work in ortho

* bevy_pbr2: Use a 90 degree y fov and light range projection for lights

* bevy_pbr2: Add AmbientLight resource

* bevy_pbr2: Convert PointLight color to linear sRGB for use in fragment shader

* bevy_pbr2: pbr.frag: Rename PointLight.projection to view_projection

The uniform contains the view_projection matrix so this was incorrect.

* bevy_pbr2: PointLight is an OmniLight as it has a radius

* bevy_pbr2: Factoring out duplicated code

* bevy_pbr2: Implement RenderAsset for StandardMaterial

* Remove unnecessary texture and sampler clones

* fix comment formatting

* remove redundant Buffer:from

* Don't extract meshes when their material textures aren't ready

* make missing textures in the queue step an error

e167a1d9cf Relicense Bevy under the dual MIT or Apache-2.0 license (#2509)
This relicenses Bevy under the dual MIT or Apache-2.0 license. For rationale, see #2373.

* Changes the LICENSE file to describe the dual license. Moved the MIT license to docs/LICENSE-MIT. Added the Apache-2.0 license to docs/LICENSE-APACHE. I opted for this approach over dumping both license files at the root (the more common approach) for a number of reasons:
  * Github links to the "first" license file (LICENSE-APACHE) in its license links (you can see this in the wgpu and rust-analyzer repos). People clicking these links might erroneously think that the apache license is the only option. Rust and Amethyst both use COPYRIGHT or COPYING files to solve this problem, but this creates more file noise (if you do everything at the root) and the naming feels way less intuitive. 
  * People have a reflex to look for a LICENSE file. By providing a single license file at the root, we make it easy for them to understand our licensing approach. 
  * I like keeping the root clean and noise free
  * There is precedent for putting the apache and mit license text in sub folders (amethyst) 
* Removed the `Copyright (c) 2020 Carter Anderson` copyright notice from the MIT license. I don't care about this attribution, it might make license compliance more difficult in some cases, and it didn't properly attribute other contributors. We shoudn't replace it with something like "Copyright (c) 2021 Bevy Contributors" because "Bevy Contributors" is not a legal entity. Instead, we just won't include the copyright line (which has precedent ... Rust also uses this approach).
* Updates crates to use the new "MIT OR Apache-2.0" license value
* Removes the old legion-transform license file from bevy_transform. bevy_transform has been its own, fully custom implementation for a long time and that license no longer applies.
* Added a License section to the main readme
* Updated our Bevy Plugin licensing guidelines.

As a follow-up we should update the website to properly describe the new license.

Closes #2373

- Slight change to `IntoChainSystem` signature and implementation.
- Remove some usages of `.system()` in the chaining example, to verify the implementation.

I swear, I'm not splitting these up on purpose, I just legit forgot about most of the things where `System` appears in public API, and my trait usage explorer mingles that with the gajillion internal uses.

ecb78048cf [ecs] Improve Commands performance (#2332)
# Objective

- Currently `Commands` are quite slow due to the need to allocate for each command and wrap it in a `Box<dyn Command>`.
- For example:
```rust
fn my_system(mut cmds: Commands) {
    cmds.spawn().insert(42).insert(3.14);
}
```
will have 3 separate `Box<dyn Command>` that need to be allocated and ran.

## Solution

- Utilize a specialized data structure keyed `CommandQueueInner`. 
- The purpose of `CommandQueueInner` is to hold a collection of commands in contiguous memory. 
- This allows us to store each `Command` type contiguously in memory and quickly iterate through them and apply the `Command::write` trait function to each element.

85a10eccc5 Fix AssetServer::get_asset_loader deadlock (#2395)
# Objective

Fixes a possible deadlock between `AssetServer::get_asset_loader` / `AssetServer::add_loader`

A thread could take the `extension_to_loader_index` read lock,
and then have the `server.loader` write lock taken in add_loader
before it can. Then add_loader can't take the extension_to_loader_index
lock, and the program deadlocks.

To be more precise:

## Step 1: Thread 1 grabs the `extension_to_loader_index` lock on lines 138..139:

3a1867a92e/crates/bevy_asset/src/asset_server.rs (L133-L145)

## Step 2: Thread 2 grabs the `server.loader` write lock on line 107:

3a1867a92e/crates/bevy_asset/src/asset_server.rs (L103-L116)

## Step 3: Deadlock, since Thread 1 wants to grab `server.loader` on line 141...:

3a1867a92e/crates/bevy_asset/src/asset_server.rs (L133-L145)

... and Thread 2 wants to grab 'extension_to_loader_index` on lines 111..112:

3a1867a92e/crates/bevy_asset/src/asset_server.rs (L103-L116)


## Solution

Fixed by descoping the extension_to_loader_index lock, since
`get_asset_loader` doesn't need to hold the read lock on the extensions map for the duration,
just to get a copyable usize. The block might not be needed,
I think I could have gotten away with just inserting a `copied()`
call into the chain, but I wanted to make the reasoning clear for
future maintainers.

b911a005d9 Mention creation of disjoint Querys with Without<T> in conflicting access Panic (#2413)
# Objective

Beginners semi-regularly appear on the Discord asking for help with using `QuerySet` when they have a system with conflicting data access.
This happens because the Resulting Panic message only mentions `QuerySet` as a solution, even if in most cases `Without<T>` was enough to solve the problem.

## Solution

Mention the usage of `Without<T>` to create disjoint queries as an alternative to `QuerySet`

## Open Questions

- Is `disjoint` a too technical/mathematical word?
- Should `Without<T>` be mentioned before or after `QuerySet`?
  - Before: Using `Without<T>` should be preferred and mentioning it first reinforces this for a reader.
  - After: The Panics can be very long and a Reader could skip to end and only see the `QuerySet`

afb33234db Optional .system(), part 3 (#2422)
# Objective

- Continue work of #2398 and #2403.
- Make `.system()` syntax optional when using `.config()` API.

## Solution

- Introduce new prelude trait, `ConfigurableSystem`, that shorthands `my_system.system().config(...)` as `my_system.config(...)`.
- Expand `configure_system_local` test to also cover the new syntax.

c8e2415eaf [ecs] add StorageType documentation (#2394)
# Objective

- Add inline documentation for `StorageType`.
- Currently the README in `bevy_ecs` provides docs for `StorageType`, however, adding addition inline docs makes it simpler for users who are actively reading the source code.

## Solution
- Add inline docs.

10f2dd3ec5 Optional .system(), part 2 (#2403)
# Objective

- Extend work done in #2398.
- Make `.system()` syntax optional when using system descriptor API.

## Solution

- Slight change to `ParallelSystemDescriptorCoercion` signature and implementors.

I haven't touched exclusive systems, because it looks like the only two other solutions are going back to doubling our system insertion methods, or starting to lean into stageless. The latter will invalidate the former, so I think exclusive systems should remian pariahs until stageless.

I can grep & nuke `.system()` thorughout the codebase now, which might take a while, or we can do that in subsequent PR(s).

c893b99224 Optional .system (#2398)
This can be your 6 months post-christmas present.

# Objective

- Make `.system` optional
- yeet
- It's ugly
- Alternative title: `.system` is dead; long live `.system`
- **yeet**

## Solution

- Use a higher ranked lifetime, and some trait magic.

N.B. This PR does not actually remove any `.system`s, except in a couple of examples. Once this is merged we can do that piecemeal across crates, and decide on syntax for labels.

1bc34b4e67 bevy_utils: Re-introduce with_capacity(). (#2393)
# Objective
Re-introduce `AHashExt` and respective `with_capacity()` implementations to give a more ergonomic way to set a `HashMap` / `HashSet` capacity.

As a note, this has also been discussed and agreed on issue #2115, which this PR addresses (leaving `new()` out of the `AHashExt` trait).

Fixes #2115.

## Solution
PR #1235 had removed the `AHashExt` trait and respective `with_capacity()`s implementations, leaving only the less ergonomic `HashMap::with_capacity_and_hasher(size, Default::default())` option available.

This re-introduces `AHashExt` and respective `with_capacity()` implementations to give a more ergonomic way to set a `HashMap` / `HashSet` capacity.

52e8a19a39 Fixes Timer Precision Error Causing Panic (#2362)
# Objective

Fixes #2361 

## Solution

Uses integer division instead of floating-point which prevents precision errors, I think.

b8f3d9c365 Allow Option<NonSend<T>> and Option<NonSendMut<T>> as SystemParam (#2345)
# Objective

Currently, you can add `Option<Res<T>` or `Option<ResMut<T>` as a SystemParam, if the Resource could potentially not exist, but this functionality doesn't exist for `NonSend` and `NonSendMut`

## Solution

Adds implementations to use `Option<NonSend<T>>` and Option<NonSendMut<T>> as SystemParams.

f71f93c843 Derive Clone for Time (#2360)
# Objective

- Make it so that `Time` can be cloned
- Makes it so I can clone the entire current `Time` and easily pass it to the user in [Rusty Engine](https://github.com/CleanCut/rusty_engine) instead of [doing this](8302dc3914/src/game.rs (L147-L150))

## Solution

- Derive the `Clone` trait on `Time`

00d8d5d5a0 fix clippy warning failing on CI (#2353)
# Objective

- CI jobs are starting to fail due to `clippy::bool-assert-comparison` and `clippy::single_component_path_imports` being triggered.

## Solution

- Fix all uses where `asset_eq!(<condition>, <bool>)` could be replace by `assert!`
- Move the `#[allow()]` for `single_component_path_imports` to `#![allow()]` at the start of the files.

71bf07f5c0 [assets] Fix AssetServer::get_handle_path (#2310)
# Objective

- Currently `AssetServer::get_handle_path` always returns `None` since the inner hash map is never written to.

## Solution

- Inside the `load_untracked` function, insert the asset path into the map.

This is similar to #1290 (thanks @TheRawMeatball)

b07b2f524e implement DetectChanges for NonSendMut (#2326)
# Objective

- The `DetectChanges` trait is used for types that detect change on mutable access (such as `ResMut`, `Mut`, etc...)
- `DetectChanges` was not implemented for `NonSendMut`

## Solution

- implement `NonSendMut` in terms of `DetectChanges`

63047b2417 Fix bad bounds for NonSend SystemParams (#2325)
# Objective

Currently, you can't call `is_added` or `is_changed` on a `NonSend` SystemParam, unless the Resource is a Component (implements `Send` and `Sync`). 
This defeats the purpose of providing change detection for NonSend Resources.
While fixing this, I also noticed that `NonSend` does not have a bound at all on its struct.

## Solution

Change the bounds of `T` to always be `'static`.

5b0f40f3f1 Document FromType trait (#2323)
# Objective

Prevent future unnecessary mental effort spent figuring out why this trait exists and how to resolve the `TODO`.

## Solution

I happened to notice this trait being used when expanding the `#[derive(Reflect)]` macro in my own crate to figure out how it worked, and noticed that there was a `TODO` comment on it because it is only used in the derive macro and thus appeared to be unused.

I figured I should document my findings to prevent someone else from finding them out the hard way in the future 😆
