Make from_reflect_or_world also try ReflectDefault and improve some comments and panic messages (#12499)
# Objective

- `from_reflect_or_world` is an internal utilty used in the
implementations of `ReflectComponent` and `ReflectBundle` to create a
`T` given a `&dyn Reflect` by trying to use `FromReflect`, and if that
fails it falls back to `ReflectFromWorld`
- reflecting `FromWorld` is not intuitive though: often it is implicitly
implemented by deriving `Default` so people might not even be aware of
it.
- the panic messages mentioning `ReflectFromWorld` are not directly
correlated to what the user would have to do (reflect `FromWorld`)

## Solution

- Also check for `ReflectDefault` in addition to `ReflectFromWorld`.
- Change the panic messages to mention the reflected trait rather than
the `Reflect*` types.

---

## Changelog

- `ReflectComponent` and `ReflectBundle` no longer require `T:
FromReflect` but instead only `T: Reflect`.
- `ReflectComponent` and `ReflectBundle` will also work with types that
only reflected `Default` and not `FromWorld`.

## Migration Guide

- `ReflectBundle::insert` now requires an additional `&TypeRegistry`
parameter.

Update App:is_plugin_added to work inside Plugin::finish and Plugin::clean (#12761)
# Objective

I have been trying to check for the existing of some plugins via
`App::is_plugin_added` to conditionally run some behaviour in the
`Plugin::finish` part of my plugin, before realizing that the plugin
registry is actually not available during this step.
This is because the `App::is_plugin_added` using the plugin registry to
check for previous registration.

## Solution

- Switch the `App::is_plugin_added` to use the list of plugin names to
check for previous registrations
- Add a unit test showcasing that `App::is_plugin_added` works during
`Plugin::finish`

Implement GPU frustum culling. (#12889)
This commit implements opt-in GPU frustum culling, built on top of the
infrastructure in https://github.com/bevyengine/bevy/pull/12773. To
enable it on a camera, add the `GpuCulling` component to it. To
additionally disable CPU frustum culling, add the `NoCpuCulling`
component. Note that adding `GpuCulling` without `NoCpuCulling`
*currently* does nothing useful. The reason why `GpuCulling` doesn't
automatically imply `NoCpuCulling` is that I intend to follow this patch
up with GPU two-phase occlusion culling, and CPU frustum culling plus
GPU occlusion culling seems like a very commonly-desired mode.

Adding the `GpuCulling` component to a view puts that view into
*indirect mode*. This mode makes all drawcalls indirect, relying on the
mesh preprocessing shader to allocate instances dynamically. In indirect
mode, the `PreprocessWorkItem` `output_index` points not to a
`MeshUniform` instance slot but instead to a set of `wgpu`
`IndirectParameters`, from which it allocates an instance slot
dynamically if frustum culling succeeds. Batch building has been updated
to allocate and track indirect parameter slots, and the AABBs are now
supplied to the GPU as `MeshCullingData`.

A small amount of code relating to the frustum culling has been borrowed
from meshlets and moved into `maths.wgsl`. Note that standard Bevy
frustum culling uses AABBs, while meshlets use bounding spheres; this
means that not as much code can be shared as one might think.

This patch doesn't provide any way to perform GPU culling on shadow
maps, to avoid making this patch bigger than it already is. That can be
a followup.

## Changelog

### Added

* Frustum culling can now optionally be done on the GPU. To enable it,
add the `GpuCulling` component to a camera.
* To disable CPU frustum culling, add `NoCpuCulling` to a camera. Note
that `GpuCulling` doesn't automatically imply `NoCpuCulling`.

Restore dragons to their seat of power (#13124)
# Objective

- There is an unfortunate lack of dragons in the meshlet docs.
- Dragons are symbolic of majesty, power, storms, and meshlets.
- A dragon habitat such as our docs requires cultivation to ensure each
winged lizard reaches their fullest, fiery selves.

## Solution

- Fix the link to the dragon image.
- The link originally targeted the `meshlet` branch, but that was later
deleted after it was merged into `main`.

---

## Changelog

- Added a dragon back into the `MeshletPlugin` documentation.

Meshlet LOD-compatible two-pass occlusion culling (#12898)
Keeping track of explicit visibility per cluster between frames does not
work with LODs, and leads to worse culling (using the final depth buffer
from the previous frame is more accurate).

Instead, we need to generate a second depth pyramid after the second
raster pass, and then use that in the first culling pass in the next
frame to test if a cluster would have been visible last frame or not.

As part of these changes, the write_index_buffer pass has been folded
into the culling pass for a large performance gain, and to avoid
tracking a lot of extra state that would be needed between passes.

Prepass previous model/view stuff was adapted to work with meshlets as
well.

Also fixed a bug with materials, and other misc improvements.

Add error when extract resource build fails (#4964)
# Objective

- Provide feedback when an extraction plugin fails to add its system.

I had some troubleshooting pain when this happened to me, as the panic
only tells you a resource is missing. This PR adds an error when the
ExtractResource plugin is added before the render world exists, instead
of silently failing.

Fix CameraProjection panic and improve CameraProjectionPlugin (#11808)
# Objective

Fix https://github.com/bevyengine/bevy/issues/11799 and improve
`CameraProjectionPlugin`

## Solution

`CameraProjectionPlugin` is now an all-in-one plugin for adding a custom
`CameraProjection`. I also added `PbrProjectionPlugin` which is like
`CameraProjectionPlugin` but for PBR.

P.S. I'd like to get this merged after
https://github.com/bevyengine/bevy/pull/11766.

---

## Changelog

- Changed `CameraProjectionPlugin` to be an all-in-one plugin for adding
a `CameraProjection`
- Removed `VisibilitySystems::{UpdateOrthographicFrusta,
UpdatePerspectiveFrusta, UpdateProjectionFrusta}`, now replaced with
`VisibilitySystems::UpdateFrusta`
- Added `PbrProjectionPlugin` for projection-specific PBR functionality.

## Migration Guide

`VisibilitySystems`'s `UpdateOrthographicFrusta`,
`UpdatePerspectiveFrusta`, and `UpdateProjectionFrusta` variants were
removed, they were replaced with `VisibilitySystems::UpdateFrusta`

Cleanup extract_meshes (#13026)
# Objective

- clean up extract_mesh_(gpu/cpu)_building

## Solution

- gpu_building no need to hold  `prev_render_mesh_instances`
- using `insert_unique_unchecked` instead of simple insert as we know
all entities are unique
- direcly get `previous_input_index ` in par_loop 


## Performance
this should also bring a slight performance win.

Throttle render assets (#12622)
# Objective

allow throttling of gpu uploads to prevent choppy framerate when many
textures/meshes are loaded in.

## Solution

- `RenderAsset`s can implement `byte_len()` which reports their size.
implemented this for `Mesh` and `Image`
- users can add a `RenderAssetBytesPerFrame` which specifies max bytes
to attempt to upload in a frame
- `render_assets::<A>` checks how many bytes have been written before
attempting to upload assets. the limit is a soft cap: assets will be
written until the total has exceeded the cap, to ensure some forward
progress every frame

notes:
- this is a stopgap until we have multiple wgpu queues for proper
streaming of data
- requires #12606

issues
- ~~fonts sometimes only partially upload. i have no clue why, needs to
be fixed~~ fixed now.
- choosing the #bytes is tricky as it should be hardware / framerate
dependent
- many features are not tested (env maps, light probes, etc) - they
won't break unless `RenderAssetBytesPerFrame` is explicitly used though

Remove version field for non-publish crates and update descriptions (#13100)
# Objective

- The [`version`] field in `Cargo.toml` is optional for crates not
published on <https://crates.io>.
- We have several `publish = false` tools in this repository that still
have a version field, even when it's not useful.

[`version`]:
https://doc.rust-lang.org/cargo/reference/manifest.html#the-version-field

## Solution

- Remove the [`version`] field for all crates where `publish = false`.
- Update the description on a few crates and remove extra newlines as
well.

Use Vec3A for 3D bounding volumes and raycasts (#13087)
# Objective

- People have reported bounding volumes being slower than their existing
solution because it doesn't use SIMD aligned types.

## Solution

- Use `Vec3A` internally for bounding volumes, accepting `Into<Vec3A>`
wherever possible
- Change some code to make it more likely SIMD operations are used.

---

## Changelog

- Use `Vec3A` for 3D bounding volumes and raycasts

## Migration Guide

- 3D bounding volumes now use `Vec3A` types internally, return values
from methods on them now return `Vec3A` instead of `Vec3`

Restructure ci modules (#13101)
# Objective

- Currently all `ci` commands are in the `subcommands` module. This is
problematic when you want to implement actually subcommands (such as
`cargo r -p ci -- doc check`).
- All command modules include the `_command` suffix, which is redundant.

## Solution

- Move `commands` modules into root crate folder.
- Merge contents of `commands/mod.rs` into `main.rs`.
- Move `commands::subcommands` module into `commands` module.
- Remove the `_command` suffix from all `commands::subcommands` modules.

Better SystemId to Entity conversions (#13090)
# Objective

- Better `SystemId` <-> `Entity` conversion.

## Solution

- Provide a method `SystemId::from_entity` to create a `SystemId<I, O>`
form an `Entity`. When users want to deal with the entities manually
they need a way to convert the `Entity` back to a `SystemId` to actually
run the system with `Commands` or `World`.
- Provide a method `SystemId::entity` that returns an `Entity` from
`SystemId`. The current `From` impl is not very discoverable as it does
not appear on the `SystemId` doc page.
- Remove old `From` impl.

## Migration Guide

```rust
let system_id = world.register_system(my_sys);

// old
let entity = Entity::from(system_id);

// new
let entity = system_id.entity();
```

Per-Object Motion Blur (#9924)
https://github.com/bevyengine/bevy/assets/2632925/e046205e-3317-47c3-9959-fc94c529f7e0

# Objective

- Adds per-object motion blur to the core 3d pipeline. This is a common
effect used in games and other simulations.
- Partially resolves #4710

## Solution

- This is a post-process effect that uses the depth and motion vector
buffers to estimate per-object motion blur. The implementation is
combined from knowledge from multiple papers and articles. The approach
itself, and the shader are quite simple. Most of the effort was in
wiring up the bevy rendering plumbing, and properly specializing for HDR
and MSAA.
- To work with MSAA, the MULTISAMPLED_SHADING wgpu capability is
required. I've extracted this code from #9000. This is because the
prepass buffers are multisampled, and require accessing with
`textureLoad` as opposed to the widely compatible `textureSample`.
- Added an example to demonstrate the effect of motion blur parameters.

## Future Improvements

- While this approach does have limitations, it's one of the most
commonly used, and is much better than camera motion blur, which does
not consider object velocity. For example, this implementation allows a
dolly to track an object, and that object will remain unblurred while
the background is blurred. The biggest issue with this implementation is
that blur is constrained to the boundaries of objects which results in
hard edges. There are solutions to this by either dilating the object or
the motion vector buffer, or by taking a different approach such as
https://casual-effects.com/research/McGuire2012Blur/index.html
- I'm using a noise PRNG function to jitter samples. This could be
replaced with a blue noise texture lookup or similar, however after
playing with the parameters, it gives quite nice results with 4 samples,
and is significantly better than the artifacts generated when not
jittering.

---

## Changelog

- Added: per-object motion blur. This can be enabled and configured by
adding the `MotionBlurBundle` to a camera entity.

Meshlet continuous LOD (#12755)
Adds a basic level of detail system to meshlets. An extremely brief
summary is as follows:
* In `from_mesh.rs`, once we've built the first level of clusters, we
group clusters, simplify the new mega-clusters, and then split the
simplified groups back into regular sized clusters. Repeat several times
(ideally until you can't anymore). This forms a directed acyclic graph
(DAG), where the children are the meshlets from the previous level, and
the parents are the more simplified versions of their children. The leaf
nodes are meshlets formed from the original mesh.
* In `cull_meshlets.wgsl`, each cluster selects whether to render or not
based on the LOD bounding sphere (different than the culling bounding
sphere) of the current meshlet, the LOD bounding sphere of its parent
(the meshlet group from simplification), and the simplification error
relative to its children of both the current meshlet and its parent
meshlet. This kind of breaks two pass occlusion culling, which will be
fixed in a future PR by using an HZB from the previous frame to get the
initial list of occluders.

Many, _many_ improvements to be done in the future
https://github.com/bevyengine/bevy/issues/11518, not least of which is
code quality and speed. I don't even expect this to work on many types
of input meshes. This is just a basic implementation/draft for
collaboration.

Arguable how much we want to do in this PR, I'll leave that up to
maintainers. I've erred on the side of "as basic as possible".

Remove async-task as a dependency (#13071)
# Objective
Follow up to #13062. As of async-executor 1.11, the crate reexports
FallibleTask, which is the only reason bevy_tasks has a direct
dependency on async-task. This should avoid the two dependencies getting
out of sync in the future and causing spurious compilation failures.

## Solution
Bump async-executor to 1.11, use the reexport, remove the dependency on
async-task.

Improve par_iter and Parallel (#12904)
# Objective

- bevy usually use `Parallel::scope` to collect items from `par_iter`,
but `scope` will be called with every satifified items. it will cause a
lot of unnecessary lookup.

## Solution

- similar to Rayon ,we introduce `for_each_init` for `par_iter` which
only be invoked when spawn a task for a group of items.

---

## Changelog

- added  `for_each_init`

## Performance
`check_visibility `  in  `many_foxes `

Contextually clearing gizmos (#10973)
# Objective
Allow `Gizmos` to work in `FixedUpdate` without any changes needed. This
changes `Gizmos` from being a purely immediate mode api, but allows the
user to use it as if it were an immediate mode API regardless of
schedule context.

Also allows for extending by other custom schedules by adding their own
`GizmoStorage<Clear>` and the requisite systems:
- `propagate_gizmos::<Clear>` before `update_gizmo_meshes`
- `stash_default_gizmos` when starting a clear context
- `pop_default_gizmos` when ending a clear context
- `collect_default_gizmos` when grabbing the requested gizmos 
- `clear_gizmos` for clearing the context's gizmos

## Solution
Adds a generic to `Gizmos` that defaults to `Update` (the current way
gizmos works). When entering a new clear context the default `Gizmos`
gets swapped out for that context's duration so the context can collect
the gizmos requested.

Prior work: https://github.com/bevyengine/bevy/pull/9153

## To do
- [x] `FixedUpdate` should probably get its own First, Pre, Update,
Post, Last system sets for this. Otherwise users will need to make sure
to order their systems before `clear_gizmos`. This could alternatively
be fixed by moving the setup of this to `bevy_time::fixed`?
   PR to fix this issue: https://github.com/bevyengine/bevy/pull/10977
- [x] use mem::take internally for the swaps?
- [x] Better name for the `Context` generic on gizmos? `Clear`?

---

## Changelog
- Gizmos drawn in `FixedMain` now last until the next `FixedMain`
iteration runs.

Small CI improvements (#13060)
# Objective

- Some CI jobs specifically use `macos-14`, as compared to the default
`macos-latest`.
- `macos-latest` is equivalent to `macos-12`, but may be updated in the
future.
- The CI job that tests on the minimum supported Rust version (MSRV)
uses environmental variables to save the toolchain version.
  - This specific usage is what step outputs were designed for.
- Both do the same thing, but step outputs can be checked by the [Github
Actions VSCode
Extension](https://marketplace.visualstudio.com/items?itemName=GitHub.vscode-github-actions).
- Some workflows have a `NIGHTLY_TOOLCHAIN` variable that let us pin the
nightly version, in case a new release breaks CI.

## Solution

- Document why certain actions required `macos-14`.
- Switch MSRV step to use step outputs.
- Add a small comment documenting the purpose of the `NIGHTLY_TOOLCHAIN`
environmental variable.

Additional doc aliases for WindingOrder in bevy_math (#13065)
# Objective

Adds a few extra `#[doc(alias)]` entries to the
`bevy_math::primitives::WindingOrder` enum and its variants to improve
searchability.

## Solution

- Add "Orientation" for `WindingOrder` itself
- Add "AntiClockwise" for `CounterClockwise` variant
- Add "Collinear" for `Invalid` variant

These alternate terms seem to be quite common, especially in the
contexts of rendering and collision-detection.

Make AppExit more specific about exit reason. (#13022)
# Objective

Closes #13017.

## Solution

- Make `AppExit` a enum with a `Success` and `Error` variant.
- Make `App::run()` return a `AppExit` if it ever returns.
- Make app runners return a `AppExit` to signal if they encountered a
error.

---

## Changelog

### Added

- [`App::should_exit`](https://example.org/)
- [`AppExit`](https://docs.rs/bevy/latest/bevy/app/struct.AppExit.html)
to the `bevy` and `bevy_app` preludes,

### Changed

- [`AppExit`](https://docs.rs/bevy/latest/bevy/app/struct.AppExit.html)
is now a enum with 2 variants (`Success` and `Error`).
- The app's [runner
function](https://docs.rs/bevy/latest/bevy/app/struct.App.html#method.set_runner)
now has to return a `AppExit`.
-
[`App::run()`](https://docs.rs/bevy/latest/bevy/app/struct.App.html#method.run)
now also returns the `AppExit` produced by the runner function.


## Migration Guide

- Replace all usages of
[`AppExit`](https://docs.rs/bevy/latest/bevy/app/struct.AppExit.html)
with `AppExit::Success` or `AppExit::Failure`.
- Any custom app runners now need to return a `AppExit`. We suggest you
return a `AppExit::Error` if any `AppExit` raised was a Error. You can
use the new [`App::should_exit`](https://example.org/) method.
- If not exiting from `main` any other way. You should return the
`AppExit` from `App::run()` so the app correctly returns a error code if
anything fails e.g.
```rust
fn main() -> AppExit {
    App::new()
        //Your setup here...
        .run()
}
```

- Closes #12968

## Solution

Correctly handle UI hierarchy without a camera (#12816)
# Objective
Add support so bevy_ui can correctly handle an UI hierarchy without a
camera present.

- Fixes #12184

## Solution

As there was no default behavior for what should happen when a camera is
not present in a UI hierarchy, the solution
was based in defining that default behavior and improving the overall
handling of this "exception".


## Changelog

- Create default values to be used in upsert_node
- Add flag to control warnings about no camera present
- Create unit test no_camera_ui (to test if ui handles no camera
present)

Parallel event reader (#12554)
# Objective

Allow parallel iteration over events, resolve #10766

## Solution

- Add `EventParIter` which works similarly to `QueryParIter`,
implementing a `for_each{_with_id}` operator.
I chose to not mirror `EventIteratorWithId` and instead implement both
operations on a single struct.
- Reuse `BatchingStrategy` from `QueryParIter`

## Changelog

- `EventReader` now supports parallel event iteration using
`par_read().for_each(|event| ...)`.

ButtonInput docs - performance cost adjustment (#13047)
Adjusted the documentation to better describe the performance cost of
`ButtonInput::any_just_pressed|any_just_released|any_pressed`.

Each function iterates the full input, but each check is expected
constant cost. It was described previously as a full input check, and a
full internal list iteration, which I believe is incorrect.

use a u64 for MeshPipelineKey (#13015)
# Objective

- `MeshPipelineKey` use some bits for two things
- First commit in this PR adds an assertion that doesn't work currently
on main
- This leads to some mesh topology not working anymore, for example
`LineStrip`
- With examples `lines`, there should be two groups of lines, the blue
one doesn't display currently

## Solution

- Change the `MeshPipelineKey` to be backed by a `u64` instead, to have
enough bits
