Split Camera.hdr out into a new component (#18873)
# Objective

- Simplify `Camera` initialization
- allow effects to require HDR

## Solution

- Split out `Camera.hdr` into a marker `Hdr` component

## Testing

- ran `bloom_3d` example

---

## Showcase

```rs
// before
commands.spawn((
  Camera3d
  Camera {
    hdr: true
    ..Default::default()
  }
))

// after
commands.spawn((Camera3d, Hdr));

// other rendering components can require that the camera enables hdr!
// currently implemented for Bloom, AutoExposure, and Atmosphere.
#[require(Hdr)]
pub struct Bloom;

Explanation for the '2d shapes' example (#19211)
[Explanation](https://bevyengine.org/learn/contribute/helping-out/explaining-examples/)
for the 2d shapes example, taken from the original HackMD document and
edited a bit.

This example is a strange one, it's eye-catching mostly because it's the
first example (at time of writing) in the examples page. That being
said, the example does a decent amount of teaching utility to it: we can
explain the bevy math-shape to mesh pipeline, which illuminates a way of
transforming one form of data (abstract, mathematical shape
descriptions) into another (meshes) which may be novel or inspirational
to some users.

bevy_reflect: Split up the std module (#18939)
> [!important]
> To **maintainers**: we should wait to merge this one in until after
#18944 lands so that cherry-picking the latter for 0.16.1 is simpler.

# Objective

The `std` module is where we implement the reflection traits for types
that are exported from `std` (including `core` and `alloc`). Over time,
this file has grown increasingly large, making it difficult to navigate
and a pain point for merge conflicts.

The goal of this PR is to break up the module into smaller chunks.

## Solution

The `std` module has been split into many submodules:
- `alloc`
- `bevy_platform`
- `core`
- `std`

Each of these new modules is comprised of submodules that closely
resemble the actual module. For example, the impls for
`::alloc::vec::Vec` have been moved to
`bevy_reflect::impls::alloc::vec::Vec`.

Some liberties were taken. For example, `Cow<'static, Path>` was kept in
`bevy_reflect::impls::std::path` rather than
`bevy_reflect::impls::alloc::borrow`.

You may ask: _Isn't this a little overkill? Why does the one-line impl
for `TypeId` need its own file?_

And yes, it is partly overkill. But the benefit with this approach is
that where an `std`-related type should live is mostly unambiguous. If
we wanted to reflect `::core::net::Ipv4Addr`, it's very clear that it
should be done in `bevy_reflect::impls::core::net`.

We can discuss better ways of breaking this up if people have other
ideas or opinions, but I think this is a pretty straightforward way of
doing it.

### Note to Reviewers

The code is pretty much copy-paste from the mega module to the new
submodules. It's probably best to focus efforts on reviewing the general
module structure, as well as maybe which impls are included where.

You _can_ review the code contained within each impl, but I promise you
the only thing I touched were the paths in the macros so they could be
more hygienic :)

## Testing

You can just check that everything compiles still:

```
cargo check -p bevy_reflect --tests
```

Move trigger_screenshots to finish() (#19204)
# Objective

- The tigger_screenshots system gets added in `.build()` but relies on a
resource that is only inserted in `.finish()`
- This isn't a bug for most users, but when doing headless mode testing
it can technically work without ever calling `.finish()` and did work
before bevy 0.15 but while migrating my work codebase I had an issue of
test failing because of this

## Solution

- Move the trigger_screenshots system to `.finish()`

## Testing

- I ran the screenshot example and it worked as expected

Optional explicit compressed image format support (#19190)
# Objective

- Allow compressed image formats to be used with `ImagePlugin` and
`GltfPlugin` in cases where there is no `RenderDevice` resource. (For
example, when using a custom render backend)

## Solution

- Define a `CompressedImageFormatSupport` component that allows the user
to explicitly determine which formats are supported.

~~Not sure if this is the best solution. Alternatively, I considered
initializing CompressedImageFormatSupport from render device features
separately, it would need to run after the render device is initialized
but before `ImagePlugin` and `GltfPlugin` finish. Not sure where the
best place for that to happen would be.~~

Update: decided on going with @greeble-dev solution: defining the
`CompressedImageFormatSupport` resource in `bevy_image`, but letting
`bevy_render` register the resource value.

don't filter dragged entity out of DragEnter events (#19179)
## produce a DragEnter event when reentering the dragged entity

when making a piano, i want dragging across the keys to trigger the
notes of each key, but currently if i drag out of a key, then back to
it, this will not work since the dragged entity gets filtered out

## Solution

- make DragEnter event work whenever there's an entry. if the user wants
to ignore the dragged entity they can compare `target` and `dragged`

## Testing

- tested this with a modified version of the 2d_shapes example. i added
an observer to the entities: (and added mesh picking plugin)
```rust
.observe(|t: Trigger<Pointer<DragEnter>>| {
    info!("entered {}, started from {}", t.target(), t.dragged);
}
```
- i'm not sure if other things need more testing, or if this is wrong
completely and breaks other things i don't know of!

Nonmax all rows (#19132)
# Objective

Since #18704 is done, we can track the length of unique entity row
collections with only a `u32` and identify an index within that
collection with only a `NonMaxU32`. This leaves an opportunity for
performance improvements.

## Solution

- Use `EntityRow` in sparse sets.
- Change table, entity, and query lengths to be `u32` instead of
`usize`.
- Keep `batching` module `usize` based since that is reused for events,
which may exceed `u32::MAX`.
- Change according `Range<usize>` to `Range<u32>`. This is more
efficient and helps justify safety.
- Change `ArchetypeRow` and `TableRow` to wrap `NonMaxU32` instead of
`u32`.

Justifying `NonMaxU32::new_unchecked` everywhere is predicated on this
safety comment in `Entities::set`: "`location` must be valid for the
entity at `index` or immediately made valid afterwards before handing
control to unknown code." This ensures no entity is in two table rows
for example. That fact is used to argue uniqueness of the entity rows in
each table, archetype, sparse set, query, etc. So if there's no
duplicates, and a maximum total entities of `u32::MAX` none of the
corresponding row ids / indexes can exceed `NonMaxU32`.

Remove warning from Image::resize (#19116)
# Objective

`Image::resize` currently prints a warning when resizing an
uninitialized `Image`, even though the resizing works correctly. For
[code](c92f14c9e7/crates/bevy_ui/src/widget/viewport.rs (L175-L179))
that doesn't care about whether the image is initialized CP-side, this
is inconvenient and unnecessary.

separate border colors (#18682)
# Objective

allow specifying the left/top/right/bottom border colors separately for
ui elements

fixes #14773

## Solution

- change `BorderColor` to 
```rs
pub struct BorderColor {
    pub left: Color,
    pub top: Color,
    pub right: Color,
    pub bottom: Color,
}
```
- generate one ui node per distinct border color, set flags for the
active borders
- render only the active borders

i chose to do this rather than adding multiple colors to the
ExtractedUiNode in order to minimize the impact for the common case
where all border colors are the same.

## Testing

modified the `borders` example to use separate colors:


![image](https://github.com/user-attachments/assets/5d9a4492-429a-4ee1-9656-215511886164)

the behaviour is a bit weird but it mirrors html/css border behaviour.

---

## Migration:

To keep the existing behaviour, just change `BorderColor(color)` into
`BorderColor::all(color)`.

Better macro errors for get_struct_fields (#17639)
# Objective

- Currently, the error span for `get_struct_field` when encountering an
enum or union points to the macro invocation, rather than the `enum` or
`union` token. It also doesn't mention which macro reported the error.

## Solution

- Report the correct error span
- Add parameter for passing in the name of the macro invocation

## Testing

Bevy compiles fine with this change

## Migration Guide

```rs
// before
let fields = get_struct_fields(&ast.data);

// after
let fields = get_struct_fields(&ast.data, "derive(Bundle)");
```

Remove upcasting methods + Cleanup interned label code (#18984)
Hiya!

# Objective

- Remove upcasting methods that are no longer necessary since Rust 1.86.
- Cleanup the interned label code.
 
## Notes
- I didn't try to remove the upcasting methods from `bevy_reflect`, as
there appears to be some complexity related to remote type reflection.
- There are likely some other upcasting methods floating around.

## Testing
I ran the `breakout` example to check that the hashing/eq
implementations of the labels are still correct.

bevy_ecs: forward type_id in InfallibleSystemWrapper (#18931)
similar to https://github.com/bevyengine/bevy/pull/12030

# Objective

`bevy_mod_debugdump` uses the `SystemTypeSet::system_type` to look up
constrains like `(system_1, system_2.after(system_1))`. For that it
needs to find the type id in `schedule.graph().systems()`

Now with systems being wrapped in an `InfallibleSystemWrapper` this
association was no longer possible.

## Solution

By forwarding the type id in `InfallibleSystemWrapper`,
`bevy_mod_debugdump` can resolve the dependencies as before, and the
wrapper is an unnoticable implementation detail.

## Testing

- `cargo test -p bevy_ecs`
I'm not sure what exactly could break otherwise.

Fix BRP query failing when specifying missing/invalid components (#18871)
# Objective

- Fixes #18869.

## Solution

The issue was the `?` after a `Result` raising the error, instead of
treating it.
Instead it is handled with `ok`, `and_then`, `map` ...

_Edit: I added the following logic._
On `bevy/query` remote requests, when `strict` is false:
- Unregistered components in `option` and `without` are ignored.
- Unregistered components in `has` are considered absent from the
entity.
- Unregistered components in `components` and `with` result in an empty
response since they specify hard requirements.

I made the `get_component_ids` function return a
`AnyhowResult<(Vec<(TypeId, ComponentId)>, Vec<String>)>` instead of the
previous `AnyhowResult<Vec<(TypeId, ComponentId)>>`; that is I added the
list of unregistered components.

## Testing

I tested changes using the same procedure as in the linked issue:
```sh
cargo run --example server --features="bevy_remote"
```
In another terminal:
```sh
# Not strict:
$ curl -X POST http://localhost:15702 -H "Content-Type: application/json" -d '{ "jsonrpc": "2.0", "method": "bevy/query", "id": 0, "params": { "data": { "components": [ "foo::bar::MyComponent" ] } } }'

Enable accessibility features for the button example (#18749)
# Objective

Accessibility features don't work with the UI `button` example because
`InputFocus` must be set for the accessibility systems to recognise the
button.

Fixes #18760

## Solution

* Set the button entity as the `InputFocus` when it is hovered or
pressed.
* Call `set_changed` on the `Button` component when the button's state
changes to hovered or pressed (the accessibility system's only update
the button's state when the `Button` component is marked as changed).

## Testing

Install NVDA, it should say "hover" when the button is hovered and
"pressed" when the button is pressed.

The bounds of the accessibility node are reported incorrectly. I thought
we fixed this, I'll take another look at it. It's not a problem with
this PR.

Add debug build option to build-wasm-example (#19312)
## Objective

- Add a `--debug` flag to `build-wasm-example` to support debug builds
for WebGL2/WebGPU targets.
- Fixes #18464

## Solution
- Added `--debug` flag to build Wasm examples in debug mode.
- Default remains release mode if `--debug` is not specified.
- Updated documentation to describe the new flag and usage.

## Testing
- Verified debug and release builds for WebGL2 and WebGPU respectively.
- Confirmed wasm artifacts are placed in the correct target dir for each
build profile:
  - Debug: `target/wasm32-unknown-unknown/debug/examples/`
  - Release: `target/wasm32-unknown-unknown/release/examples/`
- Confirmed wasm-bindgen output is written to:
`examples/wasm/target/debug` , `examples/wasm/target/release`
- Haven't actually tested running the example

| Backend | Profile | Artifacts written | Build success    |
|---------|---------|-------------------|------------------|
| webgl2 | debug | ✓ | ✓ |
| webgl2 | release | ✓ | ✓ |
| webpgu | debug | ✓ | ✓ |

Fixed the side effects of #19287
Fixes Examples that modify gltf materials are broken #19322

## Solution

Add GltfMeshName component and Deref implementations

Stores mesh names from glTF files in GltfMeshName component rather than
Name component, making both GltfMeshName and GltfMaterialName behave
like strings via Deref.


## Testing

cargo run --example depth_of_field
cargo run --example lightmaps
cargo run --example mixed_lighting
They are consistent with the situation before the error occurred.

Diagnostic reset sum ema (#19337)
# Objective

Fix incorrect average returned by `Diagnostic` after `clear_history` is
called.

## Solution

Reset sum and ema values in `Diagnostic::clear_history`.

## Testing

I have added a cargo test for `Diagnostic::clear_history` that checks
average and smoothed average. This test passes, and should not be
platform dependent.

Add documentation and examples of [ScheduleLabel] usage. (#19329)
## Objective

Add documentation useful to users of `bevy_ecs` not also using `App`.

Fixes #19270.

## Solution

* Add explanation of labels to `Schedule` documentation.
* Add example of `derive(ScheduleLabel)` to `trait ScheduleLabel`.
* Add a third example to `Schedule` which demonstrates using a schedule
via label instead of owning it directly.
* Add further explanation and links to `World::add_schedule()`, and
`World::run_schedule()`.

## Testing

Reviewed generated documentation.

Please review this documentation carefully for correctness, as I have
little experience with `bevy_ecs` and I am adding this information
because it would have helped my own past confusion, but I may still be
wrong about how things should be done.

Rename Condition to SystemCondition` (#19328)
# Objective
Fixes #19120 

## Solution
Use the find and replace token feature in VSCode to replace all the
`Condition`s with `SystemCondition`s. Then look through all the
documentation with find and replace to replace all the `Condition`s
there.

## Testing

- Did you test these changes? If so, how?
Yes, used cargo clippy, cargo build and cargo test.
- Are there any parts that need more testing?
Nope
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
By compiling and running bevy
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
Shouldn't be, but Fedora Linux with KDE Wayland

Fix Anchor component inconsistancies (#18393)
## Objective

Fix the misleading 2d anchor API where `Anchor` is a component and
required by `Text2d` but is stored on a field for sprites.

Fixes #18367

## Solution

Remove the `anchor` field from `Sprite` and require `Anchor` instead.

## Migration Guide

The `anchor` field has been removed from `Sprite`. Instead the `Anchor`
component is now a required component on `Sprite`.

UI Node Gradients (#18139)
# Objective

Allowing drawing of UI nodes with a gradient instead of a flat color.

## Solution

The are three gradient structs corresponding to the three types of
gradients supported: `LinearGradient`, `ConicGradient` and
`RadialGradient`. These are then wrapped in a `Gradient` enum
discriminator which has `Linear`, `Conic` and `Radial` variants.

Each gradient type consists of the geometric properties for that
gradient and a list of color stops.
Color stops consist of a color, a position or angle and an optional
hint. If no position is specified for a stop, it's evenly spaced between
the previous and following stops. Color stop positions are absolute, if
you specify a list of stops:
```vec![vec![ColorStop::new(RED, Val::Percent(90.), ColorStop::new(Color::GREEN, Val::Percent(10.))```
the colors will be reordered and the gradient will transition from green at 10% to red at 90%. 

Colors are interpolated between the stops in SRGB space. The hint is a normalized value that can be used to shift the mid-point where the colors are mixed 50-50.  between the stop with the hint and the following stop.

For sharp stops with no interpolated transition, place two stops at the same position.

`ConicGradient`s and RadialGradient`s have a center which is set using the new `Position` type. `Position` consists of a normalized (relative to the UI node) `Vec2` anchor point and a responsive x, y offset.

To draw a UI node with a gradient you insert the components `BackgroundGradient` and `BorderGradient`, which both newtype a vector of `Gradient`s. If you set a background color, the background color is drawn first and the gradient(s) are drawn on top.

The implementation is deliberately simple and self contained. The shader draws the gradient in multiple passes which is quite inefficient for gradients with a very large number of color stops. It's simple though and there won't be any compatibility issues. We could make gradients a specialization for `UiPipeline` but I used a separate pipeline plugin for now to ensure that these changes don't break anything. 

#### Not supported in this PR
* Interpolation in other color spaces besides SRGB. 
* Images and text: This would need some breaking changes like a `UiColor` enum type with `Color` and `Gradient` variants, to enable `BorderColor`, `TextColor`, `BackgroundColor` and `ImageNode::color` to take either a `Color` or a gradient.
* Repeating gradients

## Testing

Includes three examples that can be used for testing:
```
cargo run --example linear_gradients
cargo run --example stacked_gradients
cargo run --example radial_gradients
```

Most of the code except the components API is contained within the `bevy_ui/src/render/linear_gradients` module.
There are no changes to any existing systems or plugins except for the addition of the gradients rendering systems to the render world schedule and the `Val` changes from #18164 .

        .add_systems(Startup, setup)
        .add_observer(on_scene_load)
        .run();
}

        Transform::from_xyz(0.7, 0.7, 1.0).looking_at(Vec3::new(0.0, 0.3, 0.0), Vec3::Y),
    ));

    commands.spawn((DirectionalLight {
        shadows_enabled: true,
        ..default()
    },));

    commands.spawn(SceneRoot(asset_server.load(
        GltfAssetLabel::Scene(0).from_asset("models/FlightHelmet/FlightHelmet.gltf"),

    for child in children.iter_descendants(target) {
        let name = if let Ok(name) = names.get(child) {
            Some(name.to_string())

Fix spot light shadow glitches (#19273)
# Objective

Spot light shadows are still broken after fixing point lights in #19265

## Solution

Fix spot lights in the same way, just using the spot light specific
visible entities component. I also changed the query to be directly in
the render world instead of being extracted to be more accurate.

## Testing

Tested with the same code but changing `PointLight` to `SpotLight`.

Add boilerplate docs for PointerHits::new and HitData::new (#19259)
# Objective

Add documentation for the last two functions in bevy_picking that are
missing them.

## Solution

Add boilerplate "Constructs an X" to `PointerHits::new()` and
`HitData::new()`.

This form of no-information documentation of `new()` functions is used
in several places in the repo, and @alice-i-cecile agreed that this is a
reasonable approach - the params are already documented on the fields
within the struct definition.

Remove YAxisOrientation from bevy_text (#19077)
# Objective

Been looking for simplifications in the text systems as part of the text
input changes.

This enum isn't very helpful I think. We can remove it and the
associated parameters and instead just negate the glyph's y-offsets in
`extract_text2d_sprite`.

## Solution

Remove the `YAxisOrientation` enum and parameters. 
Queue text sprites relative to the top-left in `extract_text2d_sprite`
and negate the glyph's y-offset.

## Testing

The `text2d` example can be used for testing:

cargo run --example text2d

Per world error handler (#18810)
# Objective

[see original
comment](https://github.com/bevyengine/bevy/pull/18801#issuecomment-2796981745)
> Alternately, could we store it on the World instead of a global? I
think we have a World nearby whenever we call default_error_handler().
That would avoid the need for atomics or locks, since we could do
ordinary reads and writes to the World.

Global error handlers don't actually need to be global – per world is
enough. This allows using different handlers for different worlds and
also removes the restrictions on changing the handler only once.

## Solution

Each `World` can now store its own error handler in a resource.

For convenience, you can also set the default error handler for an
`App`, which applies it to the worlds of all `SubApp`s. The old behavior
of only being able to set the error handler once is kept for apps.

We also don't need the `configurable_error_handler` feature anymore now.

## Testing

New/adjusted tests for failing schedule systems & observers.

## Showcase

```rust
App::new()
    .set_error_handler(info)

Make sure prepass notices changes in alpha mode (#19170)
# Objective

Fixes #19150

## Solution

Normally the `validate_cached_entity` in 

86cc02dca2/crates/bevy_pbr/src/prepass/mod.rs (L1109-L1126)
marks unchanged entites as clean, which makes them remain in the phase.

If a material is changed to an `alpha_mode` that isn't supposed to be
added to the prepass pipeline, the specialization system just
`continue`s and doesn't indicate to the cache that the entity is not
clean anymore.

I made these invalid entities get removed from the pipeline cache so
that they are correctly not marked clean and then removed from the
phase.

## Testing

Tested with the example code from the issue.
