# Objective
- UI materials reserve too much capacity in a vec: for every node in the
transparent phase, it reserves enough memory to store all the nodes
- Update #10437
## Solution
- Only reserve extra memory if there's not enough
- Only reserve the needed memory, not more
# Objective
- Make progress for #15918
- Start with 2d
## Solution
- Remove screenshots for existing examples as they're not deterministic
- Create new "testbed" example category, with a 2d one to start
## Testing
- Run `CI_TESTING_CONFIG=.github/example-run/testbed_2d.ron cargo run
--example testbed_2d --features "bevy_ci_testing"`
- ???
- Check the screenshots
# Objective
In `queue_shadows`, the `UiBoxShadows` option is unwrapped incorrectly
which results in the number of shadow samples being set to
`u32::default()` instead of `UiBoxShadows::default()` if the camera
entity doesn't have the component.
## Solution
Just use `unwrap_or_default` directly without `map`.
# Objective
Remove `bevy-ui`'s non-functional "bevy_text" feature.
Fixes#15900
## Solution
Remove all the "bevy_text" cfg gates.
I tried to fix it at first but couldn't figure it out. I'll happily
withdraw this in favour of another PR that gets the feature gate
working.
# Objective
`TextFont` and `TextColor` is not registered in the app type registry
and serializing a scene with a a `Text2d` doesn't save the color and
font of the text entity.
## Solution
register `TextFont` and `TextColor` in the type registry
# Objective
In PR #15812 ImageLoader was moved from bevy_render to bevy_image but a
reference to old path was left in a meta file used by `asset_settings`
example. This resulted in one of sprites used by this example to not be
displayed.
Fixes#15932
## Solution
Correct the loader reference in the meta file used by `asset_settings`
example (I've found no other meta files referencing this loader).
## Testing
I've run `bevy_assets` example. It now displays 3 sprites (as expected)
and outputs no errors.
## Migration Guide
This PR obviously requires no migration guide as this is just a bug-fix,
but I believe that #15812 should mention that meta files needs updating.
Proposal:
* Asset loader name must be updated in `.meta` files for images.
Change: `loader: "bevy_render::texture::image_loader::ImageLoader",`
to: `loader: "bevy_image::image_loader::ImageLoader",`
It will fix the following error: ``no `AssetLoader` found with the name
'bevy_render::texture::image_loader::ImageLoader``
# Objective
Limited implementation of the CSS property `overflow-clip-margin`
https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-clip-margin
Allows you to control the visible area for clipped content when using
overfllow-clip, -hidden, or -scroll and expand it with a margin.
Based on #15442Fixes#15468
## Solution
Adds a new field to Style: `overflow_clip_margin: OverflowClipMargin`.
The field is ignored unless overflow-clip, -hidden or -scroll is set on
at least one axis.
`OverflowClipMargin` has these associated constructor functions:
```
pub const fn content_box() -> Self;
pub const fn padding_box() -> Self;
pub const fn border_box() -> Self;
```
You can also use the method `with_margin` to increases the size of the
visible area:
```
commands
.spawn(NodeBundle {
style: Style {
width: Val::Px(100.),
height: Val::Px(100.),
padding: UiRect::all(Val::Px(20.)),
border: UiRect::all(Val::Px(5.)),
overflow: Overflow::clip(),
overflow_clip_margin: OverflowClipMargin::border_box().with_margin(25.),
..Default::default()
},
border_color: Color::BLACK.into(),
background_color: GRAY.into(),
..Default::default()
})
```
`with_margin` expects a length in logical pixels, negative values are
clamped to zero.
## Notes
* To keep this PR as simple as possible I omitted responsive margin
values support. This could be added in a follow up if we want it.
* CSS also supports a `margin-box` option but we don't have access to
the margin values in `Node` so it's probably not feasible to implement
atm.
## Testing
```cargo run --example overflow_clip_margin```
<img width="396" alt="overflow-clip-margin" src="https://github.com/user-attachments/assets/07b51cd6-a565-4451-87a0-fa079429b04b">
## Migration Guide
Style has a new field `OverflowClipMargin`. It allows users to set the visible area for clipped content when using overflow-clip, -hidden, or -scroll and expand it with a margin.
There are three associated constructor functions `content_box`, `padding_box` and `border_box`:
* `content_box`: elements painted outside of the content box area (the innermost part of the node excluding the padding and border) of the node are clipped. This is the new default behaviour.
* `padding_box`: elements painted outside outside of the padding area of the node are clipped.
* `border_box`: elements painted outside of the bounds of the node are clipped. This matches the behaviour from Bevy 0.14.
There is also a `with_margin` method that increases the size of the visible area by the given number in logical pixels, negative margin values are clamped to zero.
`OverflowClipMargin` is ignored unless overflow-clip, -hidden or -scroll is also set on at least one axis of the UI node.

# Objective
- This is a followup to #15812.
## Solution
I just deleted the `COUNT` const and replaced it. I didn't realize for
loops are not const yet, so improving the other const variables is not
obvious.
Note: `slice::len` has been const since Rust 1.39, so we're not relying
on a brand new feature or anything.
## Testing
- It builds!
# Objective
On HEAD, `bevy_color` does not compile on its own with `--all-features`
enabled. This PR fixes that.
## Solution
- Added the `curve` feature on `bevy_math` to `bevy_color`.
- Added the `serialize` feature on `bevy_math` to
`bevy_color/serialize`.
## Testing
- Compiled with `cargo b -p bevy_color --all-features` on HEAD and on
this PR: it fails to compile on HEAD but compiles with this PR.
# Objective
- Fix bug where `cargo run -p ci` fails due to differing implementations
for default values between `Default` trait and `argh`
- Automatically install target via `rustup` to make first-run simpler.
## Solution
The command will now attempt to install the target via `rustup` by
default, which will provide a cleaner error message if a malformed
target is passed. It will also avoid confusion when people attempt to
use this tool for the first time without the target already installed.
I've added a flag, --skip-install, to disable the attempted installation
just-in-case. (e.g., maybe rustup isn't in their path but cargo is?).
Also fixed a bug where the default value for `target` was different
between the `Default` trait and `argh`, causing `cargo run -p ci` to
fail.
## Testing
- CI
- Subcommand ran directly
## Notes
This issue was originally discovered by @targrub (on Discord):
> Unfortunately, running `cargo run -p ci` still gives that same error
as I initially reported (though `cargo run -p ci --
compile-check-no-std` succeeds). This is after having run `rustup target
add x86_64-unknown-none`.
# Objective
- `C: ExtractComponent` inserts `C::Out` instead of `C`, so we need to
remove `C::Out`. cc #15904.
## Solution
- `C` -> `C::Out`
## Testing
- CAS has `<ContrastAdaptiveSharpening as ExtractComponent>::Out =
(DenoiseCas, CasUniform)`. Setting its strength to zero correctly
removes the effect after this change.
# Objective
Add an example for the new drag move and drag resize introduced by PR
#15674 and fix#15734.
## Solution
I created an example that allows the user to exercise drag move and drag
resize separately. The user can also choose what direction the resize
works in.
### Name
The example is called `window_drag_move`. Happy to have that
bikeshedded.
### Contentious Refactor?
This PR removed the `ResizeDirection` enumeration in favor of using
`CompassOctant` which had the same variants. Perhaps this is
contentious.
### Unsafe?
In PR #15674 I mentioned that `start_drag_move()` and
`start_drag_resize()`'s requirement to only be called in the presence of
a left-click looks like a compiler-unenforceable contract that can cause
intermittent panics when not observed, so perhaps the functions should
be marked them unsafe. **I have not made that change** here since I
didn't see a clear consensus on that.
## Testing
I exercised this on x86 macOS. However, winit for macOS does not support
drag resize. It reports a good error when `start_drag_resize()` is
called. I'd like to see it tested on Windows and Linux.
---
## Showcase
Example window_drag_move shows how to drag or resize a window without
decoration.

# Objective
Make `StableInterpolate` "just work" on tuples whose parts are each
`StableInterpolate` types. These types arise notably through
`Curve::zip` (or just through explicit mapping of a similar form). It
would otherwise be kind of frustrating to stumble upon such a thing and
then realize that, e.g., automatic resampling just doesn't work, even
though there is a very "obvious" way to do it.
## Solution
Infer `StableInterpolate` on tuples of up to size 11. I can make that
number bigger, if desired. Unfortunately, I don't think that our
standard "fake variadics" tools actually work for this; the anonymous
field accessors of tuples are `:tt` for purposes of macro expansion,
which means that you can't simplify away the identifiers by doing
something clever like using recursion (which would work if they were
`:expr`). Maybe someone who knows some incredibly dark magic could chime
in with a better solution.
The expanded impls look like this:
```rust
impl<
T0: StableInterpolate,
T1: StableInterpolate,
T2: StableInterpolate,
T3: StableInterpolate,
T4: StableInterpolate,
> StableInterpolate for (T0, T1, T2, T3, T4)
{
fn interpolate_stable(&self, other: &Self, t: f32) -> Self {
(
<T0 as StableInterpolate>::interpolate_stable(&self.0, &other.0, t),
<T1 as StableInterpolate>::interpolate_stable(&self.1, &other.1, t),
<T2 as StableInterpolate>::interpolate_stable(&self.2, &other.2, t),
<T3 as StableInterpolate>::interpolate_stable(&self.3, &other.3, t),
<T4 as StableInterpolate>::interpolate_stable(&self.4, &other.4, t),
)
}
}
```
## Testing
Expanded macros; it compiles.
## Future
Make a version of the fake variadics workflow that supports this kind of
thing.
# Objective
Closes#15799.
Many rendering people and maintainers are in favor of reverting default
mesh materials added in #15524, especially as the migration to required
component is already large and heavily breaking.
## Solution
Revert default mesh materials, and adjust docs accordingly.
- Remove `extract_default_materials`
- Remove `clear_material_instances`, and move the logic back into
`extract_mesh_materials`
- Remove `HasMaterial2d` and `HasMaterial3d`
- Change default material handles back to pink instead of white
- 2D uses `Color::srgb(1.0, 0.0, 1.0)`, while 3D uses `Color::srgb(1.0,
0.0, 0.5)`. Not sure if this is intended.
There is now no indication at all about missing materials for `Mesh2d`
and `Mesh3d`. Having a mesh without a material renders nothing.
## Testing
I ran `2d_shapes`, `mesh2d_manual`, and `3d_shapes`, with and without
mesh material components.
# Objective
- Make the example deterministic when run with CI, so that the
[screenshot
comparison](https://thebevyflock.github.io/bevy-example-runner/) is
stable
- Preserve the "truly random on each run" behavior so that every page
load in the example showcase shows a different contributor first
## Solution
- Fall back to the static default contributor list in CI
- Store contributors in a `Vec` so that we can show repeats of the
fallback contributor list, giving the appearance of lots of overlapping
contributors in CI
- Use a shared seeded RNG throughout the app
- Give contributor birds a `z` value so that their depth is stable
- Remove the shuffle, which was redundant because contributors are first
collected into a hashmap
- `chain` the systems so that the physics is deterministic from run to
run
## Testing
```bash
echo '(setup: (fixed_frame_time: Some(0.05)), events: [(100, Screenshot), (500, AppExit)])' > config.ron
CI_TESTING_CONFIG=config.ron cargo run --example contributors --features=bevy_ci_testing
mv screenshot-100.png screenshot-100-a.png
CI_TESTING_CONFIG=config.ron cargo run --example contributors --features=bevy_ci_testing
diff screenshot-100.png screenshot-100-a.png
```
## Alternatives
I'd also be fine with removing this example from the list of examples
that gets screenshot-tested in CI. Coverage from other 2d examples is
probably adequate.

# Objective
Fixes#15730.
## Solution
As part of #15586, we made a constant to store all the supported image
formats. However since the `ImageFormat` does actually include Hdr and
OpenExr, it also included the `"hdr"` and `"exr"` file extensions. These
are supported by separate loaders though: `HdrTextureLoader` and
`ExrTextureLoader`. This led to a warning about duplicate asset loaders.
Therefore, instead of having the constant for `ImageFormat`, I made the
constant just for `ImageLoader`. This lets us correctly remove `"hdr"`
and `"exr"` from the image formats supported by `ImageLoader`, returning
us to having a single asset loader for every image format.
Note: we could have just removed `hdr` and `exr` from
`ImageFormat::SUPPORTED_FILE_EXTENSIONS`, but this would be very
confusing. Then the list of `ImageFormat`s would not match the list of
supported formats!
## Testing
- I ran the `sprite` example and got no warning! I also replaced the
sprite in that example with an HDR file and everything worked as
expected.
See #15924 for more details
close#15924
from the issue, this code panic:
```rust
use bevy::time::Stopwatch;
use std::time::Duration;
fn main() {
let second = Duration::from_secs(1);
let mut stopwatch = Stopwatch::new();
// lot of time has passed... or a timer with Duration::MAX that was artificially set has "finished":
// timer.set_elapsed(timer.remaining());
stopwatch.set_elapsed(Duration::MAX);
// panic
stopwatch.tick(second);
let mut stopwatch = Stopwatch::new();
stopwatch.set_elapsed(Duration::MAX - second);
// this doesnt panic as its still one off the max
stopwatch.tick(second);
// this panic
stopwatch.tick(second);
}
```
with this PR changes, the code now doesn't panic.
have a good day !

## Solution
- Despawn light view entities when they go unused or when the
corresponding view is not alive.

- modified an example to try toggling shadows for all kinds of light:

# Objective
Ensure that components that are conditionally extracted do not linger in
the render world when not extracted from the main world.
## Solution
If the `ExtractComponent` returns `None`, we'll remove the render world
component. I think this is the most sensible behavior here. In the
future if there really is a use case for keeping the previous render
component around, we could add a `Option<Self::Out>` parameter for the
previous render component to the method, or something similar. I think
that this follows the principle of least surprise here relative to what
`None` would suggest and the way that render nodes are typically
written. The alternative would be to add an `enabled` field to pretty
much every camera settings component, or duplicate the extraction
condition as #15856 does.
## Testing
`transmission` no longer crashes.
## Migration Guide
Components that implement `ExtractComponent` and return `None` will
cause the extracted component to be removed from the render world.
# Objective
Currently, is is very painful to wait for an asset to load from the
context of an `async` task. While bevy's `AssetServer` is asynchronous
at its core, the public API is mainly focused on being used from
synchronous contexts such as bevy systems. Currently, the best way of
waiting for an asset handle to finish loading is to have a system that
runs every frame, and either listens for `AssetEvents` or manually polls
the asset server. While this is an acceptable interface for bevy
systems, it is extremely awkward to do this in a way that integrates
well with the `async` task system. At my work we had to create our own
(inefficient) abstraction that encapsulated the boilerplate of checking
an asset's load status and waking up a task when it's done.
## Solution
Add the method `AssetServer::wait_for_asset`, which returns a future
that suspends until the asset associated with a given `Handle` either
finishes loading or fails to load.
## Testing
- CI

# Objective

I wrote some docs. I doubt these are perfect; I'm probably far too close
to this for that to be the case. :)
# Objective
Benchmark overhead of validation for:
- `DynSystemParam`,
- `ParamSet`,
- combinator systems.
Needed for #15606
## Solution
As noted in objective, I've added 3 benchmarks, where each uses an
excessive amount of the specific functionality.
I benchmark on the level of schedules, rather than individual
`validate_param` calls, so we get a better idea how changes to the code
impact memory-lookup, etc. related side effects.

# Objective
Cleanup naming and docs, add missing migration guide after #15591
All text root nodes now use `Text` (UI) / `Text2d`.
All text readers/writers use `Text<Type>Reader`/`Text<Type>Writer`
convention.
---
## Migration Guide
Doubles as #15591 migration guide.
Text bundles (`TextBundle` and `Text2dBundle`) were removed in favor of
`Text` and `Text2d`.
Shared configuration fields were replaced with `TextLayout`, `TextFont`
and `TextColor` components.
Just `TextBundle`'s additional field turned into `TextNodeFlags`
component,
while `Text2dBundle`'s additional fields turned into `TextBounds` and
`Anchor` components.
Text sections were removed in favor of hierarchy-based approach.
For root text entities with `Text` or `Text2d` components, child
entities with `TextSpan` will act as additional text sections.
To still access text spans by index, use the new `TextUiReader`,
`Text2dReader` and `TextUiWriter`, `Text2dWriter` system parameters.
# Objective
This is a follow-up to #15650. While the core `Image` stuff moved from
`bevy_render` to `bevy_image`, the `ImageLoader` and the
`CompressedImageSaver` remained in `bevy_render`.
## Solution
I moved `ImageLoader` and `CompressedImageSaver` to `bevy_image` and
re-exported everything out from `bevy_render`. The second step isn't
strictly necessary, but `bevy_render` is already doing this for all the
other `bevy_image` types, so I kept it the same for consistency.
Unfortunately I had to give `ImageLoader` a constructor so I can keep
the `RenderDevice` stuff in `bevy_render`.
## Testing
It compiles!
## Migration Guide
- `ImageLoader` can no longer be initialized directly through
`init_asset_loader`. Now you must use
`app.register_asset_loader(ImageLoader::new(supported_compressed_formats))`
(check out the implementation of `bevy_render::ImagePlugin`). This only
affects you if you are initializing the loader manually and does not
affect users of `bevy_render::ImagePlugin`.
## Followup work
- We should be able to move most of the `ImagePlugin` to `bevy_image`.
This would likely require an `ImagePlugin` and a `RenderImagePlugin` or
something though.
# Objective
- Closes#14774
## Solution
Added:
```rust
impl<'w, E, B: Bundle> Trigger<'w, E, B> {
pub fn components(&self) -> &[ComponentId];
}
```
I went with storing it in the trigger as a `SmallVec<[Component; 1]>`
because a singular target component will be the most common case, and it
remains the same size as `Vec<ComponentId>`.
## Testing
Added a test.
# Objective
Change UI clipping to respect borders and padding.
Fixes#15335
## Solution
Based on #15163
1. Add a `padding` field to `Node`.
2. In `ui_layout_size` copy the padding values from taffy to
`Node::padding`.
4. Determine the node's content box (The innermost part of the node
excluding the padding and border).
5. In `update_clipping` perform the clipping intersection with the
node's content box.
## Notes
* `Rect` probably needs some helper methods for working with insets but
because `Rect` and `BorderRect` are in different crates it's awkward to
add them. Left for a follow up.
* We could have another `Overflow` variant (probably called
`Overflow::Hidden`) to that clips inside of the border box instead of
the content box. Left it out here as I'm not certain about the naming or
behaviour though. If this PR is adopted, it would be trivial to add a
`Hidden` variant in a follow up.
* Depending on UI scaling there are sometimes gaps in the layout:
<img width="532" alt="rounding-bug"
src="https://github.com/user-attachments/assets/cc29aa0d-44fe-403f-8f0e-cd28a8b1d1b3">
This is caused by existing bugs in `ui_layout_system`'s coordinates
rounding and not anything to do with the changes in this PR.
## Testing
This PR also changes the `overflow` example to display borders on the
overflow nodes so you can see how this works:
#### main (The image is clipped at the edges of the node, overwriting
the border).

Another clippy-lint fix: the goal is so that `ci lints` actually
displays the problems that a contributor caused, and not a bunch of
existing stuff in the repo. (when run on nightly)
## Solution
This fixes all but the `clippy::needless_lifetimes` lint, which will
result in substantially more fixes and be in other PR(s). I also
explicitly allow `non_local_definitions` since it is [not working
correctly, but will be
fixed](https://github.com/rust-lang/rust/issues/131643).
A few things were manually fixed: for example, some places had an
explicitly defined `div_ceil` function that was used, which is no longer
needed since this function is stable on unsigned integers. Also, empty
lines in doc comments were handled individually.
## Testing
I ran `cargo clippy --workspace --all-targets --all-features --fix
--allow-staged` with the `clippy::needless_lifetimes` lint marked as
`allow` in `Cargo.toml` to avoid fixing that too. It now passes with all
but the listed lint.

# Objective
- Compare screenshots for a few examples between PRs and main
## Solution
- Send screenshots taken to a screenshot comparison service
- Not completely sure every thing will work at once, but it shouldn't
break anything at least
- it needs a secret to work, I'll add it if enough people agree with
this PR
- this PR doesn't change anything on the screenshot selection (load_gltf
and breakout currently), this will need rendering folks input and can
happen later

# Objective
- Android doesn't receive lifecycle event `Suspended` before suspension
## Solution
- Fix update triggering just after state change on android
## Testing
- Tested on the android emulator
# Objective
Fixes#15847
Alternative to #15862. Would appreciate a rendering person signaling
preference for one or the other.
## Solution
Partially revert the changes made to this example in #15524.
Add comment explaining that the non-usage of the built-in color vertex
attribute is intentional.
## Testing
`cargo run --example mesh2d_manual`
# Objective
The type `AssetLoadError` has `PartialEq` and `Eq` impls, which is
problematic due to the fact that the `AssetLoaderError` and
`AddAsyncError` variants lie in their impls: they will return `true` for
any `Box<dyn Error>` with the same `TypeId`, even if the actual value is
different. This can lead to subtle bugs if a user relies on the equality
comparison to ensure that two values are equal.
The same is true for `DependencyLoadState`,
`RecursiveDependencyLoadState`.
More generally, it is an anti-pattern for large error types involving
dynamic dispatch, such as `AssetLoadError`, to have equality
comparisons. Directly comparing two errors for equality is usually not
desired -- if some logic needs to branch based on the value of an error,
it is usually more correct to check for specific variants and inspect
their fields.
As far as I can tell, the only reason these errors have equality
comparisons is because the `LoadState` enum wraps `AssetLoadError` for
its `Failed` variant. This equality comparison is only used to check for
`== LoadState::Loaded`, which we can easily replace with an `is_loaded`
method.
## Solution
Remove the `{Partial}Eq` impls from `LoadState`, which also allows us to
remove it from the error types.
## Migration Guide
The types `bevy_asset::AssetLoadError` and `bevy_asset::LoadState` no
longer support equality comparisons. If you need to check for an asset's
load state, consider checking for a specific variant using
`LoadState::is_loaded` or the `matches!` macro. Similarly, consider
using the `matches!` macro to check for specific variants of the
`AssetLoadError` type if you need to inspect the value of an asset load
error in your code.
`DependencyLoadState` and `RecursiveDependencyLoadState` are not
released yet, so no migration needed,

# Objective
#15320 is a particularly painful breaking change, and the new
`RenderEntity` in particular is very noisy, with a lot of `let entity =
entity.id()` spam.
## Solution
Implement `WorldQuery`, `QueryData` and `ReadOnlyQueryData` for
`RenderEntity` and `WorldEntity`.
These work the same as the `Entity` impls from a user-facing
perspective: they simply return an owned (copied) `Entity` identifier.
This dramatically reduces noise and eases migration.
Under the hood, these impls defer to the implementations for `&T` for
everything other than the "call .id() for the user" bit, as they involve
read-only access to component data. Doing it this way (as opposed to
implementing a custom fetch, as tried in the first commit) dramatically
reduces the maintenance risk of complex unsafe code outside of
`bevy_ecs`.
To make this easier (and encourage users to do this themselves!), I've
made `ReadFetch` and `WriteFetch` slightly more public: they're no
longer `doc(hidden)`. This is a good change, since trying to vendor the
logic is much worse than just deferring to the existing tested impls.
## Testing
I've run a handful of rendering examples (breakout, alien_cake_addict,
auto_exposure, fog_volumes, box_shadow) and nothing broke.
## Follow-up
We should lint for the uses of `&RenderEntity` and `&MainEntity` in
queries: this is just less nice for no reason.

# Objective
- closes#15866
## Solution
- Simply migrate where possible.
## Testing
- Expect that CI will do most of the work. Examples is another way of
testing this, as most of the work is in that area.
---
## Notes
For now, this PR doesn't migrate `QueryState::single` and friends as for
now, this look like another issue. So for example, QueryBuilders that
used single or `World::query` that used single wasn't migrated. If there
is a easy way to migrate those, please let me know.
Most of the uses of `Query::single` were removed, the only other uses
that I found was related to tests of said methods, so will probably be
removed when we remove `Query::single`.
# Objective
`insert_or_spawn_batch` exists, but a version for just inserting doesn't
- Closes#2693
- Closes#8384
- Adopts/supersedes #8600
## Solution
Add `insert_batch`, along with the most common `insert` variations:
- `World::insert_batch`
- `World::insert_batch_if_new`
- `World::try_insert_batch`
- `World::try_insert_batch_if_new`
- `Commands::insert_batch`
- `Commands::insert_batch_if_new`
- `Commands::try_insert_batch`
- `Commands::try_insert_batch_if_new`
## Testing
Added tests, and added a benchmark for `insert_batch`.
Performance is slightly better than `insert_or_spawn_batch` when only
inserting:

<summary>old benchmark</summary>
This was before reworking it to remove the `UnsafeWorldCell`:

---
## Showcase
Usage is the same as `insert_or_spawn_batch`:
```
use bevy_ecs::{entity::Entity, world::World, component::Component};
#[derive(Component)]
struct A(&'static str);
#[derive(Component, PartialEq, Debug)]
struct B(f32);
let mut world = World::new();
let entity_a = world.spawn_empty().id();
let entity_b = world.spawn_empty().id();
world.insert_batch([
(entity_a, (A("a"), B(0.0))),
(entity_b, (A("b"), B(1.0))),
]);
assert_eq!(world.get::<B>(entity_a), Some(&B(0.0)));
```
# Objective
- Required components replace bundles, but `SpatialBundle` is yet to be
deprecated
## Solution
- Deprecate `SpatialBundle`
- Insert `Transform` and `Visibility` instead in examples using it
- In `spawn` or `insert` inserting a default `Transform` or `Visibility`
with component already requiring either, remove those components from
the tuple
## Testing
- Did you test these changes? If so, how?
Yes, I ran the examples I changed and tests
- Are there any parts that need more testing?
The `gamepad_viewer` and and `custom_shader_instancing` examples don't
work as intended due to entirely unrelated code, didn't check main.
- How can other people (reviewers) test your changes? Is there anything
specific they need to know?
Run examples, or just check that all spawned values are identical
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
Linux, wayland trough x11 (cause that's the default feature)
---
## Migration Guide
`SpatialBundle` is now deprecated, insert `Transform` and `Visibility`
instead which will automatically insert all other components that were
in the bundle. If you do not specify these values and any other
components in your `spawn`/`insert` call already requires either of
these components you can leave that one out.
before:
```rust
commands.spawn(SpatialBundle::default());
```
after:
```rust
commands.spawn((Transform::default(), Visibility::default());
```
