Retrieve the stack_index from Node in extract_ui_material_nodes instead of walking UiStack (#15104)
# Objective

 `ExtractedUiMaterialNode` is still walking the whole `UiStack`. 

more info: https://github.com/bevyengine/bevy/pull/9853

## Solution

Retrieve the `stack_index` from the `Node` component instead.
Also changed the `stack_index` field of `ExtractedUiMaterialNode` to
`u32`.

Add rect field to UI image (#15095)
# Objective

Fixes #14424 

## Solution

Add a rect field to UiImage, and update the extraction of ui images and
slices.

## Testing

I tested all possible combinations of having a rect, using a texture
atlas, setting image scale mode to sliced and image scale mode to tiled.
See the showcase section.

bevy_pbr: Make choosing of diffuse indirect lighting explicit. (#15093)
# Objective

Make choosing of diffuse indirect lighting explicit, instead of using
numerical conditions like `all(indirect_light == vec3(0.0f))`, as using
that may lead to unwanted light leakage.

## Solution

Use an explicit `found_diffuse_indirect` condition to indicate the found
indirect lighting source.

## Testing

I have tested examples `lightmaps`, `irradiance_volumes` and
`reflection_probes`, there are no visual changes. For further testing,
consider a "cave" scene with lightmaps and irradiance volumes. In the
cave there are some purly dark occluded area, those dark area will
sample the irradiance volume, and that is easy to leak light.

Add common aspect ratio constants and improve documentation (#15091)
Hello,

I'd like to contribute to this project by adding some useful constants
and improving the documentation for the AspectRatio struct. Here's a
summary of the changes I've made:

1. Added new constants for common aspect ratios:
   - SIXTEEN_NINE (16:9)
   - FOUR_THREE (4:3)
   - ULTRAWIDE (21:9)

2. Enhanced the overall documentation:
   - Improved module-level documentation with an overview and use cases
   - Expanded explanation of the AspectRatio struct with examples
- Added detailed descriptions and examples for all methods (both
existing and new)
   - Included explanations for the newly introduced constant values
   - Added clarifications for From trait implementations

These changes aim to make the AspectRatio API more user-friendly and
easier to understand. The new constants provide convenient access to
commonly used aspect ratios, which I believe will be helpful in many
scenarios.

Depreciate LoadAndSave Asset Processor (#15090)
# Objective

- Fixes #15060

## Solution

- Added `IdentityAssetTransformer<A>` which is an `AssetTransformer`
which infallibly returns the input `Asset` unmodified.
- Replaced `LoadAndSave` and `LoadAndSaveSettings` with type definitions
linking back to `LoadTransformAndSave` and
`LoadTransformAndSaveSettings` respectively.
- Marked `LoadAndSave` and `LoadAndSaveSettings` as depreciated with a
migration guide included, hinting to the user to use the underlying type
instead.

## Testing

- Ran CI locally

---

## Migration Guide

- Replace `LoadAndSave<L, S>` with `LoadTransformAndSave<L,
IdentityAssetTransformer<<L as AssetLoader>::Asset>, S>`
- Replace `LoadAndSaveSettings<L, S>` with
`LoadTransformAndSaveSettings<L, (), S>`

Add set_state extension method to Commands (#15083)
# Objective

- Improve the ergonomics of managing states.

## Solution

- Add `set_state` extension method to `Commands` so you don't need to
type out `ResMut<NextState<S>>` to update a state. It also reduces
system parameter list size when you already have `Commands`.
- I only updated a couple examples to showcase how it can be used. There
*is* a potential perf cost to introducing `Commands` so this method
shouldn't necessarily be used everywhere.

## Testing

- Tested the updated examples: `game_menu` and `alien_cake_addict`.

---

## Showcase

Add `Commands::set_state` method for easily updating states.

Set directly:
```rust
fn go_to_game(mut game_state: ResMut<NextState<GameState>>) {
    game_state.set(GameState::Play);
}
```

Set with commands (**NEW**):
```rust
fn go_to_game(mut commands: Commands) {
    commands.set_state(GameState::Play);
}
```

Split OrthographicProjection::default into 2d & 3d (Adopted) (#15073)
Adopted PR from dmlary, all credit to them!
https://github.com/bevyengine/bevy/pull/9915

Original description:

# Objective

The default value for `near` in `OrthographicProjection` should be
different for 2d & 3d.

For 2d using `near = -1000` allows bevy users to build up scenes using
background `z = 0`, and foreground elements `z > 0` similar to css.
However in 3d `near = -1000` results in objects behind the camera being
rendered. Using `near = 0` works for 3d, but forces 2d users to assign
`z <= 0` for rendered elements, putting the background at some arbitrary
negative value.

There is no common value for `near` that doesn't result in a footgun or
usability issue for either 2d or 3d, so they should have separate
values.

There was discussion about other options in the discord
[0](https://discord.com/channels/691052431525675048/1154114310042292325),
but splitting `default()` into `default_2d()` and `default_3d()` seemed
like the lowest cost approach.

https://github.com/bevyengine/bevy/pull/9214,
https://github.com/bevyengine/bevy/pull/9310,
https://github.com/bevyengine/bevy/pull/9537 (thanks to @Selene-Amanita
for the list)

## Solution

This commit splits `OrthographicProjection::default` into `default_2d`
and `default_3d`.

## Migration Guide

- In initialization of `OrthographicProjection`, change `..default()` to
`..OrthographicProjection::default_2d()` or
`..OrthographicProjection::default_3d()`

Example:
```diff
--- a/examples/3d/orthographic.rs

Fix AsBindGroup sampler validation. (#15071)

Sorts the scene entries by path before serializing. (#15047)
# Objective

Fixes: https://github.com/bevyengine/bevy/issues/14515

## Solution

Sorts the iterator with itertools' sorted_by function. This is required
given that 'self.entries' is an immutable &[Box<dyn PartialReflect]
which also doesn't implement Clone or Copy.

## Testing

The modifications passed the unit testing only after they were edited to
ensure that the items were in alphabetical order.
I haven't checked for performance implications.

Add convenience methods for constructing and setting storage buffer data (#15044)
Adds some methods to assist in building `ShaderStorageBuffer` without
using `bytemuck`. We keep the `&[u8]` constructors since this is still
modeled as a thin wrapper around the buffer descriptor, but should make
it easier to interact with at the cost of an extra allocation in the
`ShaderType` path for the buffer writer.

Remove remnant EntityHash and related types from bevy_utils (#15039)
# Objective

`EntityHash` and related types were moved from `bevy_utils` to
`bevy_ecs` in #11498, but seemed to have been accidentally reintroduced
a week later in #11707.

## Solution

Remove the old leftover code.

---

## Migration Guide

- Uses of `bevy::utils::{EntityHash, EntityHasher, EntityHashMap,
EntityHashSet}` now have to be imported from `bevy::ecs::entity`.

Make QueryFilter an unsafe trait (#14790)

    println!("Still have & at {f:p}");
});
```

prints: 

```
Got &mut at     0x1924b92dfb0
Got & at        0x1924b92dfb0
Got &mut at     0x1924b92dfb0
Still have & at 0x1924b92dfb0
```

Which means it had an `&` and `&mut` alive at the same time.

The only `unsafe` there is around `Self::fetch`, but I believe that call
correctly upholds the safety invariant, and matches what `Added` and
`Changed` do.


## Solution

Make `QueryFilter` an unsafe trait and document the requirement that the
`WorldQuery` implementation be read-only.

## Migration Guide

`QueryFilter` is now an `unsafe trait`. If you were manually
implementing it, you will need to verify that the `WorldQuery`
implementation is read-only and then add the `unsafe` keyword to the
`impl`.

Replaced implicit emissive weight with default. (#13871)
Since `StandardMaterial::emissive_exposure_weight` does not get packed
into the gbuffer in the deferred case, unpacking uses an implicit
default value for emissive's alpha channel.

This resulted in divergent behavior between the forward and deferred
renderers when using standard materials with default
emissive_exposure_weight, this value defaulting to `0.0` in the forward
case and `1.0` in the other.

This patch changes the implicit value in the deferred case to `0.0` in
order to match the behavior of the forward renderer. However, this still
does not solve the case where `emissive_exposure_weight` is not `0.0`.

bevy_reflect: Refactor serde module (#15107)
# Objective

The `ser` and `de` modules in `bevy_reflect/serde` are very long and
difficult to navigate.

## Solution

Refactor both modules into many smaller modules that each have a single
primary focus (i.e. a `structs` module that only handles struct
serialization/deserialization).

I chose to keep the `ser` and `de` modules separate. We could have
instead broken it up kind (e.g. lists, maps, etc.), but I think this is
a little cleaner. Serialization and deserialization, while related, can
be very different. So keeping them separated makes sense for
organizational purposes.

That being said, if people disagree and think we should structure this a
different way, I am open to changing it.

Note that this PR's changes are mainly structural. There are a few
places I refactored code to reduce duplication and to make things a bit
cleaner, but these are largely cosmetic and shouldn't have any impact on
behavior.

### Other Details

This PR also hides a lot of the internal logic from being exported.
These were originally public, but it's unlikely they really saw any use
outside of these modules. In fact, you don't really gain anything by
using them outside of this module either.

By privatizing these fields and items, we also set ourselves up for more
easily changing internal logic around without involving a breaking
change.

I also chose not to mess around with tests since that would really blow
up the diff haha.

## Testing

You can test locally by running:

```
cargo test --package bevy_reflect --all-features
```

---

## Migration Guide

The fields on `ReflectSerializer` and `TypedReflectSerializer` are now
private. To instantiate, the corresponding constructor must be used:

```rust
// BEFORE
let serializer = ReflectSerializer {
    value: &my_value,
    registry: &type_registry,
};

// AFTER
let serializer = ReflectSerializer::new(&my_value, &type_registry);
```

Additionally, the following types are no longer public:

- `ArraySerializer`
- `EnumSerializer`
- `ListSerializer`
- `MapSerializer`
- `ReflectValueSerializer` (fully removed)
- `StructSerializer`
- `TupleSerializer`
- `TupleStructSerializer`

As well as the following traits:

- `DeserializeValue` (fully removed)

More triangles/vertices per meshlet (#15023)
### Builder changes
- Increased meshlet max vertices/triangles from 64v/64t to 255v/128t
(meshoptimizer won't allow 256v sadly). This gives us a much greater
percentage of meshlets with max triangle count (128). Still not perfect,
we still end up with some tiny <=10 triangle meshlets that never really
get simplified, but it's progress.
- Removed the error target limit. Now we allow meshoptimizer to simplify
as much as possible. No reason to cap this out, as the cluster culling
code will choose a good LOD level anyways. Again leads to higher quality
LOD trees.
- After some discussion and consulting the Nanite slides again, changed
meshlet group error from _adding_ the max child's error to the group
error, to doing `group_error = max(group_error, max_child_error)`. Error
is already cumulative between LODs as the edges we're collapsing during
simplification get longer each time.
- Bumped the 65% simplification threshold to allow up to 95% of the
original geometry (e.g. accept simplification as valid even if we only
simplified 5% of the triangles). This gives us closer to
log2(initial_meshlet_count) LOD levels, and fewer meshlet roots in the
DAG.

Still more work to be done in the future here. Maybe trying METIS for
meshlet building instead of meshoptimizer.

Using ~8 clusters per group instead of ~4 might also make a big
difference. The Nanite slides say that they have 8-32 meshlets per
group, suggesting some kind of heuristic. Unfortunately meshopt's
compute_cluster_bounds won't work with large groups atm
(https://github.com/zeux/meshoptimizer/discussions/750#discussioncomment-10562641)
so hard to test.

Based on discussion from
https://github.com/bevyengine/bevy/discussions/14998,
https://github.com/zeux/meshoptimizer/discussions/750, and discord.

### Runtime changes
- cluster:triangle packed IDs are now stored 25:7 instead of 26:6 bits,
as max triangles per cluster are now 128 instead of 64
- Hardware raster now spawns 128 * 3 vertices instead of 64 * 3 vertices
to account for the new max triangles limit
- Hardware raster now outputs NaN triangles (0 / 0) instead of
zero-positioned triangles for extra vertex invocations over the cluster
triangle count. Shouldn't really be a difference idt, but I did it
anyways.
- Software raster now does 128 threads per workgroup instead of 64
threads. Each thread now loads, projects, and caches a vertex (vertices
0-127), and then if needed does so again (vertices 128-254). Each thread
then rasterizes one of 128 triangles.
- Fixed a bug with `needs_dispatch_remap`. I had the condition backwards
in my last PR, I probably committed it by accident after testing the
non-default code path on my GPU.

Unify crate-level preludes (#15080)
# Objective

- Crate-level prelude modules, such as `bevy_ecs::prelude`, are plagued
with inconsistency! Let's fix it!

## Solution

Format all preludes based on the following rules:

1. All preludes should have brief documentation in the format of:
   > The _name_ prelude.
   >
> This includes the most common types in this crate, re-exported for
your convenience.
2. All documentation should be outer, not inner. (`///` instead of
`//!`.)
3. No prelude modules should be annotated with `#[doc(hidden)]`. (Items
within them may, though I'm not sure why this was done.)

## Testing

- I manually searched for the term `mod prelude` and updated all
occurrences by hand. 🫠

Fix bevy_ui compile error when bevy_picking feature is disabled (#15053)
# Objective

#14957 added the `pick_rounded_rect` function to `bevy_ui` in the
`picking_backend` module, which is gated behind the `bevy_picking`
feature. This function is used in that module, as well as in the `focus`
module. The latter usage is not gated behind the `bevy_picking` feature,
causing a compile error when the feature is disabled.

## Solution

Move the `pick_rounded_rect` function out of the `picking_backend`
module, as it does not depend on anything defined in that module. I put
it in `lib.rs` but it could reasonably be moved somewhere else instead.

## Testing

Encountered this compile error in a project and confirmed that this
patch fixes it.

UI outlines radius (#15018)
# Objective

Fixes #13479

This also fixes the gaps you can sometimes observe in outlines
(screenshot from main, not this PR):

<img width="636" alt="outline-gaps"
src="https://github.com/user-attachments/assets/c11dae24-20f5-4aea-8ffc-1894ad2a2b79">

The outline around the last item in each section has vertical gaps. 

## Solution

Draw the outlines with corner radius using the existing border rendering
for uinodes. The outline radius is very simple to calculate. We just
take the computed border radius of the node, and if it's greater than
zero, add it to the distance from the edge of the node to the outer edge
of the node's outline.

Picking event ordering (#14862)
# Objective

Correctly order picking events. Resolves
https://github.com/bevyengine/bevy/issues/5984.

## Solution

Event ordering [very long standing
problem](https://github.com/aevyrie/bevy_mod_picking/issues/294) with
mod picking, stemming from two related issues. The first problem was
that `Pointer<T>` events of different types couldn't be ordered, but we
have already gotten around that in the upstream by switching to
observers. Since observers run in the order they are triggered, this
isn't an issue.

The second problem was that the underlying event streams that picking
uses to create it's pointer interaction events *also* lacked ordering,
and the systems that generated the points couldn't interleave events.
This PR fixes that by unifying the event streams and integrating the
various interaction systems.

The concrete changes are as follows:
+ `bevy_winit::WinitEvent` has been moved to `bevy_window::WindowEvent`.
This provides a unified (and more importantly, *ordered*) input stream
for both `bevy_window` and `bevy_input` events.
+ Replaces `InputMove` and `InputPress` with `PointerInput`, a new
unified input event which drives picking and interaction. This event is
built to have drop-in forward compatibility with [winit's upcoming
pointer abstraction](https://github.com/rust-windowing/winit/pull/3876).
I have added code to emulate it using the current winit input
abstractions, but this entire thing will be much more robust when it
lands.
+ Rolls `pointer_events` `send_click_and_drag_events` and
`send_drag_over_events` into a single system, which operates directly on
`PointerEvent` and triggers observers as output.

The PR also improves docs and takes the opportunity to
refactor/streamline the pointer event dispatch logic.

## Status & Testing

This PR is now feature complete and documented. While it is
theoretically possible to add unit tests for the ordering, building the
picking mocking for that will take a little while.

Feedback on the chosen ordering of events is within-scope.

## Migration Guide

For users switching from `bevy_mod_picking` to `bevy_picking`:
+ Instead of adding an `On<T>` component, use `.observe(|trigger:
Trigger<T>|)`. You may now apply multiple handlers to the same entity
using this command.
+ Pointer interaction events now have semi-deterministic ordering which
(more or less) aligns with the order of the raw input stream. Consult
the docs on `bevy_picking::event::pointer_events` for current
information. You may need to adjust your event handling logic
accordingly.
+ `PointerCancel` has been replaced with `Pointer<Cancled>`, which now
has the semantics of an OS touch pointer cancel event.
+ `InputMove` and `InputPress` have been merged into `PointerInput`. The
use remains exactly the same.
+ Picking interaction events are now only accessible through observers,
and no `EventReader`. This functionality may be re-implemented later.

For users of `bevy_winit`:
+ The event `bevy_winit::WinitEvent` has moved to
`bevy_window::WindowEvent`. If this was the only thing you depended on
`bevy_winit` for, you should switch your dependency to `bevy_window`.
+ `bevy_window` now depends on `bevy_input`. The dependencies of
`bevy_input` are a subset of the existing dependencies for `bevy_window`
so this should be non-breaking.

Remove all existing system order ambiguities in DefaultPlugins (#15031)
# Objective

As discussed in https://github.com/bevyengine/bevy/issues/7386, system
order ambiguities within `DefaultPlugins` are a source of bugs in the
engine and badly pollute diagnostic output for users.

We should eliminate them!

This PR is an alternative to #15027: with all external ambiguities
silenced, this should be much less prone to merge conflicts and the test
output should be much easier for authors to understand.

Note that system order ambiguities are still permitted in the
`RenderApp`: these need a bit of thought in terms of how to test them,
and will be fairly involved to fix. While these aren't *good*, they'll
generally only cause graphical bugs, not logic ones.

## Solution

All remaining system order ambiguities have been resolved.
Review this PR commit-by-commit to see how each of these problems were
fixed.

## Testing

`cargo run --example ambiguity_detection` passes with no panics or
logging!

Return Results from Camera's world/viewport conversion methods (#14989)
# Objective

## Solution

- Add `ViewportConversionError` and return it from viewport conversion
methods on Camera.

## Testing

- I successfully compiled and ran all changed examples.

## Migration Guide

The following methods on `Camera` now return a `Result` instead of an
`Option` so that they can provide more information about failures:
 - `world_to_viewport`
 - `world_to_viewport_with_depth`
 - `viewport_to_world`
 - `viewport_to_world_2d`

Call `.ok()` on the `Result` to turn it back into an `Option`, or handle
the `Result` directly.

## Solution
1. Add a `resolved_border_radius` field to `Node` to hold the resolved
border radius values.

and store them in `Node`.
5. New `pick_rounded_rect` function based on the border radius SDF from
`ui.wgsl`.
6. Use `pick_rounded_rect` in `focus` and `picking_backend` to check if
the pointer is hovering UI nodes with rounded corners.

Updated LogPlugin Documentation with Performance Warning (#14984)
# Objective

- Fixes #14966

## Solution

- Added a _Performance_ section to the documentation for
`LogPlugin::filter` explaining that long filter strings can degrade
performance and to instead rely on `LogPlugin::level` when possible.

## Testing

- CI passed locally.

Utilise new method for 2d circle example. (#15022)
# Objective
Replaced the existing instantiation of the 2D Circle in the 2d_shapes.rs
file with the `new` method.
- Ensures consistency in instantiating 2D primitive shapes in the
examples.

## Solution
Replaced the existing instantiation of the 2D Circle in the 2d_shapes.rs
file with the `new` method.
- Ensures consistency in instantiating 2D primitive shapes in the
examples.

## Testing
- None: Should be straight-forward enough to not warrant a test (I will
eat my words if I am wrong).

Color gradient curve (#14976)
# Objective

- Currently we have the `ColorRange` trait to interpolate linearly
between two colors
- It would be cool to have:
  1. linear interpolation between n colors where `n >= 1`
  2. other kinds of interpolation

## Solution

1. Implement `ColorGradient` which takes `n >= 1` colors and linearly
interpolates between consecutive pairs of them
2. Implement `Curve` intergration for this `ColorGradient` which yields
a curve struct. After that we can apply all of the cool curve adaptors
like `.reparametrize()` and `.map()` to the gradient

## Testing

- Added doc tests
- Added tests

## Showcase

```rust
// let gradient = ColorGradient::new(vec![]).unwrap(); // panic! 💥
let gradient = ColorGradient::new([basic::RED, basic::LIME, basic::BLUE]).expect("non-empty");
let curve = gradient.to_curve();
let brighter_curve = curve.map(|c| c.mix(&basic::WHITE, 0.5));
```

UI texture atlas slice shader (#14990)
# Objective

Fixes https://github.com/bevyengine/bevy/issues/14183

## Solution

Reimplement the UI texture atlas slicer using a shader. 

The problems with #14183 could be fixed more simply by hacking around
with the coordinates and scaling but that way is very fragile and might
get broken again the next time we make changes to the layout
calculations. A shader based solution is more robust, it's impossible
for gaps to appear between the image slices with these changes as we're
only drawing a single quad.

I've not tried any benchmarks yet but it should much more efficient as
well, in the worst cases even hundreds or thousands of times faster.

Maybe could have used the UiMaterialPipeline. I wrote the shader first
and used fat vertices and then realised it wouldn't work that way with a
UiMaterial. If it's rewritten it so it puts all the slice geometry in
uniform buffer, then it might work? Adding the uniform buffer would
probably make the shader more complicated though, so don't know if it's
even worth it. Instancing is another alternative.

## Testing
The examples are working and it seems to match the old API correctly but
I've not used the texture atlas slicing API for anything before, I
reviewed the PR but that was back in January.

Needs a review by someone who knows the rendering pipeline and wgsl
really well because I don't really have any idea what I'm doing.

Cosmetic improvements for text_input example (#15016)
# Objective

Minor cosmetic improvements and code cleanup for this example

## Solution

- Use the default font and shorter constructor where the the full font
is not needed
- Use 12px padding for instruction text to match other examples
- Clean up formatting of instruction text
- Fix one instance of a font handle not being reused

Fix some examples having different instruction text positions (#15017)
# Objective

Thought I had found all of these... noticed some `10px` in #15013 and
did another sweep.

Continuation of #8478, #13583.

## Solution

- Position example text (and other elements) 12px from the edge of the
screen

Extract borders without border radius (#15020)
# Objective

The `BorderRadius` component shouldn't be required to draw borders for
nodes with sharp corners.

## Solution

Make `BorderRadius` optional in `extract_uinode_borders`'s UI node
query.
