# Objective
- Revert #10296
## Solution
- Avoid implementing `Display` without a justification
- `Display` implementation is a guarantee without a direct use, takes
additional time to compile and require work to maintain
- `Debug`, `Reflect` or `Serialize` should cover all needs
# Objective
The `BuildWorldChildren` API was missing several methods that exist in
`BuildChildren`.
## Solution
Added the methods (and tests) for consistency.
# Objective
If we add the stack index to `Node` then we don't need to walk the
`UiStack` repeatedly during extraction.
## Solution
Add a field `stack_index` to `Node`.
Update it in `ui_stack_system`.
Iterate queries directly in the UI's extraction systems.

## Changelog
* Added the field `stack_index` to `Node`.
* `ui_stack_system` updates `Node::stack_index` after a new `UiStack` is
generated.
* The UI's extraction functions iterate a query directly rather than
walking the `UiStack` and doing lookups.

This PR adds both diffuse and specular light transmission capabilities
to the `StandardMaterial`, with support for screen space refractions.
This enables realistically representing a wide range of real-world
materials, such as:
- Glass; (Including frosted glass)
- Transparent and translucent plastics;
- Various liquids and gels;
- Gemstones;
- Marble;
- Wax;
- Paper;
- Leaves;
- Porcelain.
Unlike existing support for transparency, light transmission does not
rely on fixed function alpha blending, and therefore works with both
`AlphaMode::Opaque` and `AlphaMode::Mask` materials.
## Solution
- Introduces a number of transmission related fields in the
`StandardMaterial`;
- For specular transmission:
- Adds logic to take a view main texture snapshot after the opaque
phase; (in order to perform screen space refractions)
- Introduces a new `Transmissive3d` phase to the renderer, to which all
meshes with `transmission > 0.0` materials are sent.
- Calculates a light exit point (of the approximate mesh volume) using
`ior` and `thickness` properties
- Samples the snapshot texture with an adaptive number of taps across a
`roughness`-controlled radius enabling “blurry” refractions
- For diffuse transmission:
- Approximates transmitted diffuse light by using a second, flipped +
displaced, diffuse-only Lambertian lobe for each light source.
## To Do
- [x] Figure out where `fresnel_mix()` is taking place, if at all, and
where `dielectric_specular` is being calculated, if at all, and update
them to use the `ior` value (Not a blocker, just a nice-to-have for more
correct BSDF)
- To the _best of my knowledge, this is now taking place, after
964340cdd. The fresnel mix is actually "split" into two parts in our
implementation, one `(1 - fresnel(...))` in the transmission, and
`fresnel()` in the light implementations. A surface with more
reflectance now will produce slightly dimmer transmission towards the
grazing angle, as more of the light gets reflected.
- [x] Add `transmission_texture`
- [x] Add `diffuse_transmission_texture`
- [x] Add `thickness_texture`
- [x] Add `attenuation_distance` and `attenuation_color`
- [x] Connect values to glTF loader
- [x] `transmission` and `transmission_texture`
- [x] `thickness` and `thickness_texture`
- [x] `ior`
- [ ] `diffuse_transmission` and `diffuse_transmission_texture` (needs
upstream support in `gltf` crate, not a blocker)
- [x] Add support for multiple screen space refraction “steps”
- [x] Conditionally create no transmission snapshot texture at all if
`steps == 0`
- [x] Conditionally enable/disable screen space refraction transmission
snapshots
- [x] Read from depth pre-pass to prevent refracting pixels in front of
the light exit point
- [x] Use `interleaved_gradient_noise()` function for sampling blur in a
way that benefits from TAA
- [x] Drill down a TAA `#define`, tweak some aspects of the effect
conditionally based on it
- [x] Remove const array that's crashing under HLSL (unless a new `naga`
release with https://github.com/gfx-rs/naga/pull/2496 comes out before
we merge this)
- [ ] Look into alternatives to the `switch` hack for dynamically
indexing the const array (might not be needed, compilers seem to be
decent at expanding it)
- [ ] Add pipeline keys for gating transmission (do we really want/need
this?)
- [x] Tweak some material field/function names?
## A Note on Texture Packing
_This was originally added as a comment to the
`specular_transmission_texture`, `thickness_texture` and
`diffuse_transmission_texture` documentation, I removed it since it was
more confusing than helpful, and will likely be made redundant/will need
to be updated once we have a better infrastructure for preprocessing
assets_
Due to how channels are mapped, you can more efficiently use a single
shared texture image
for configuring the following:
- R - `specular_transmission_texture`
- G - `thickness_texture`
- B - _unused_
- A - `diffuse_transmission_texture`
The `KHR_materials_diffuse_transmission` glTF extension also defines a
`diffuseTransmissionColorTexture`,
that _we don't currently support_. One might choose to pack the
intensity and color textures together,
using RGB for the color and A for the intensity, in which case this
packing advice doesn't really apply.
---
## Changelog
- Added a new `Transmissive3d` render phase for rendering specular
transmissive materials with screen space refractions
- Added rendering support for transmitted environment map light on the
`StandardMaterial` as a fallback for screen space refractions
- Added `diffuse_transmission`, `specular_transmission`, `thickness`,
`ior`, `attenuation_distance` and `attenuation_color` to the
`StandardMaterial`
- Added `diffuse_transmission_texture`, `specular_transmission_texture`,
`thickness_texture` to the `StandardMaterial`, gated behind a new
`pbr_transmission_textures` cargo feature (off by default, for maximum
hardware compatibility)
- Added `Camera3d::screen_space_specular_transmission_steps` for
controlling the number of “layers of transparency” rendered for
transmissive objects
- Added a `TransmittedShadowReceiver` component for enabling shadows in
(diffusely) transmitted light. (disabled by default, as it requires
carefully setting up the `thickness` to avoid self-shadow artifacts)
- Added support for the `KHR_materials_transmission`,
`KHR_materials_ior` and `KHR_materials_volume` glTF extensions
- Renamed items related to temporal jitter for greater consistency
## Migration Guide
- `SsaoPipelineKey::temporal_noise` has been renamed to
`SsaoPipelineKey::temporal_jitter`
- The `TAA` shader def (controlled by the presence of the
`TemporalAntiAliasSettings` component in the camera) has been replaced
with the `TEMPORAL_JITTER` shader def (controlled by the presence of the
`TemporalJitter` component in the camera)
- `MeshPipelineKey::TAA` has been replaced by
`MeshPipelineKey::TEMPORAL_JITTER`
- The `TEMPORAL_NOISE` shader def has been consolidated with
`TEMPORAL_JITTER`
# Objective
- We need to check multiple times if a color is fully transparent, e.g.
for performance optimizations.
- Make code more readable.
- Reduce code duplication, to simplify making changes if needed (e.g. if
we need to take floating point weirdness into account later on).
## Solution
- Introduce a new `Color::is_fully_transparent` helper function to
determine if the alpha of a color is 0.
- Use the helper function in our UI rendering code.
---
## Changelog
- Added `Color::is_fully_transparent` helper function.

# Objective
Right now, we flip the `world_normal` in response to `double_sided &&
!is_front`, however when calculating `N` from tangents and the normal
map, we don't flip the normal read from the normal map, which produces
extremely weird results.
## Solution
- Pass `double_sided` and `is_front` flags to the
`apply_normal_mapping()` function and use them to conditionally flip
`Nt`
## Comparison
Note: These are from a custom scene running with the `transmission`
branch, (#8015) I noticed lighting got pretty weird for the back side of
translucent `double_sided` materials whenever I added a normal map.

## Changelog
- Fixed a bug where `StandardMaterial::double_sided` would interact
incorrectly with normal maps, producing broken results.
# Objective
- Work towards GPU-driven culling
(https://github.com/bevyengine/bevy/pull/10164)
## Solution
- Pass the view frustum to the shader view uniform
---
## Changelog
- View Frustums are now extracted to the render world and made available
to shaders
# Objective
- Address inconsistent term usage in the docs for the alignment
properties for UI nodes. Fixes#10218
- `JustifyContent::Stretch` is missing despite being supported by Taffy,
being as the default value for Grids, so it should be added to Bevy as
well
## Solution
- Consistently provide links to the mdn site for the css equivalent
- Match (mostly) the documentation given on the pub struct and the
underlying enums
- Use the term `items` consistently to refer each child in the container
- Add `JustifyContent::Stretch` and map it to Taffy
## Migration Guide
- The `JustifyContents` enum has been expanded to include
`JustifyContents::Stretch`.
# Objective
Align all error-like types to implement `Error`.
Fixes #10176
## Solution
- Derive `Error` on more types
- Refactor instances of manual implementations that could be derived
This adds thiserror as a dependency to bevy_transform, which might
increase compilation time -- but I don't know of any situation where you
might only use that but not any other crate that pulls in bevy_utils.
The `contributors` example has a `LoadContributorsError` type, but as
it's an example I have not updated it. Doing that would mean either
having a `use bevy_internal::utils::thiserror::Error;` in an example
file, or adding `thiserror` as a dev-dependency to the main `bevy`
crate.
---
## Changelog
- All `…Error` types now implement the `Error` trait
# Objective
- Example `deferred_rendering` sometimes fail to render in CI
- Make it easier to render
## Solution
- Reduce the complexity of the sphere used
Existing truncation code limits the number of attribute buffers to be
less than or equal to the number of vertices.
Instead the number of elements from each attribute buffer should be
limited to the length of the shortest buffer as mentioned in the earlier
warning.
# Objective
- Fixes#10267
## Solution
- Moves the `.take()` from the outer loop of attribute buffers, to the
inner loop of attribute values.

# Objective
`normalize` method that expresses a rectangle relative to a normalized

- Fixes#10133
## Solution
- Add a new example that focuses on using `Virtual` time
## Changelog
### Added
- new `virtual_time` example
### Changed
- moved `time` & `timers` examples to the new `examples/time` folder
# Objective
- When finding the `CursorIcon` doc, it should be easier to find out
where to use it.
- When saying it is partially copied from the browser, be more clear
about the provenance and link to the spec document.
## Solution
- Link to the example code.
- Link to the CSS3 UI spec document.
Extracted the easy stuff from #8974 .
# Problem
1. Commands from `update_previous_view_projections` would crash when
matching entities were despawned.
2. `TaaPipelineId` and `draw_3d_graph` module were not public.
3. When the motion vectors pointed to pixels that are now off screen, a
smearing artifact could occur.
# Solution
1. Use `try_insert` command instead.
2. Make them public, renaming to `TemporalAntiAliasPipelineId`.
3. Check for this case, and ignore history for pixels that are
off-screen.
# Objective
- Remove special cases where `clippy::doc_markdown` lint is disabled.
## Solution
- Add default values back into `clippy.toml` by adding `".."` to the
list of `doc-valid-idents`.
- Add `"VSync"` and `"WebGL2"` to the list of `doc-valid-idents`.
- Remove all instances where `clippy::doc_markdown` is allowed.
- Fix `max_mip` formatting so that there isn't a warning.
# Objective
- Have more docs for `bevy_text` to avoid reading the source code for
some things.
## Solution
- Add some additional docs.
## Changelog
- `TextSettings.max_font_atlases` in `bevy_text` has been renamed to `
TextSettings.soft_max_font_atlases`.
## Migration Guide
- Usages of `TextSettings.max_font_atlases` from `bevy_text` must be
changed to `TextSettings.soft_max_font_atlases`.
# Situation
- In case of parent without visibility components, the visibility
inheritance of children creates a panic.
## Solution
- Apply same fallback visibility as parent not found instead of panic.
# Objective
Make it obvious why stuff renders pink when rendering stuff with bevy
with `default_features = false` and bevy's default tonemapper
(TonyMcMapFace, it requires a LUT which requires the `tonemapping_luts`,
`ktx2`, and `zstd` features).
Not sure if this should be considered as fixing these issues, but in my
previous PR (https://github.com/bevyengine/bevy/pull/9073, and old
discussions on discord that I only somewhat remember) it seemed like we
didn't want to make ktx2 and zstd required features for
bevy_core_pipeline.
Related https://github.com/bevyengine/bevy/issues/9179
Related https://github.com/bevyengine/bevy/issues/9098
## Solution
This logs an error when a LUT based tonemapper is used without the
`tonemapping_luts` feature enabled, and cleans up the default features a
bit (`tonemapping_luts` now includes the `ktx2` and `zstd` features,
since it panics without them).
Another solution would be to fall back to a non-lut based tonemapper,
but I don't like this solution as then it's not explicitly clear to
users why eg. a library example renders differently than a normal bevy
app (if the library forgot the `tonemapping_luts` feature).
I did remove the `ktx2` and `zstd` features from the list of default
features in Cargo.toml, as I don't believe anything else currently in
bevy relies on them (or at least searching through every hit for `ktx2`
and `zstd` didn't show anything except loading an environment map in
some examples), and they still show up in the `cargo_features` doc as
default features.
---
## Changelog
- The `tonemapping_luts` feature now includes both the `ktx2` and `zstd`
features to avoid a panic when the `tonemapping_luts` feature was enable
without both the `ktx2` and `zstd` feature enabled.
# Objective
- `deferred_rendering` and `load_gltf` fail in WebGPU builds due to
textureSample() being called on the diffuse environment map texture
after non-uniform control flow
## Solution
- The diffuse environment map texture only has one mip, so use
`textureSampleLevel(..., 0.0)` to sample that mip and not require UV
gradient calculation.
# Objective
- Build on the changes in https://github.com/bevyengine/bevy/pull/9982
- Use `ImageSamplerDescriptor` as the "public image sampler descriptor"
interface in all places (for consistency)
- Make it possible to configure textures to use the "default" sampler
(as configured in the `DefaultImageSampler` resource)
- Fix a bug introduced in #9982 that prevents configured samplers from
being used in Basis, KTX2, and DDS textures
---
## Migration Guide
- When using the `Image` API, use `ImageSamplerDescriptor` instead of
`wgpu::SamplerDescriptor`
- If writing custom wgpu renderer features that work with `Image`, call
`&image_sampler.as_wgpu()` to convert to a wgpu descriptor.
# Objective
- Folder handles are not shared. Loading the same folder multiple times
will result in different handles.
- Once folder handles are shared, they can no longer be manually
reloaded, so we should add support for hot-reloading them
## Solution
- Reuse folder handles based on their path
- Trigger a reload of a folder if a file contained in it (or a sub
folder) is added or removed
- This also covers adding/removing/moving sub folders containing files
---------

# Objective
- Assets v2 does not currently offer a public API to load untyped assets
## Solution
- Wrap the untyped handle in a `LoadedUntypedAsset` asset to offer a
non-blocking load for untyped assets. The user does not need to know the
actual asset type.
- Handles to `LoadedUntypedAsset` have the same path as the wrapped
asset, but their handles are shared using a label.
The user side of `load_untyped` looks like this:
```rust
use bevy::prelude::*;
use bevy_internal::asset::LoadedUntypedAsset;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Startup, setup)
.add_systems(Update, check)
.run();
}
#[derive(Resource)]
struct UntypedAsset {
handle: Handle<LoadedUntypedAsset>,
}
fn setup(
mut commands: Commands,
asset_server: Res<AssetServer>,
) {
let handle = asset_server.load_untyped("branding/banner.png");
commands.insert_resource(UntypedAsset { handle });
commands.spawn(Camera2dBundle::default());
}
fn check(
mut commands: Commands,
res: Option<Res<UntypedAsset>>,
assets: Res<Assets<LoadedUntypedAsset>>,
) {
if let Some(untyped_asset) = res {
if let Some(asset) = assets.get(&untyped_asset.handle) {
commands.spawn(SpriteBundle {
texture: asset.handle.clone().typed(),
..default()
});
commands.remove_resource::<UntypedAsset>();
}
}
}
```
---
## Changelog
- `load_untyped` on the asset server now returns a handle to a
`LoadedUntypedAsset` instead of an untyped handle to the asset at the
given path. The untyped handle for the given path can be retrieved from
the `LoadedUntypedAsset` once it is done loading.
## Migration Guide
Whenever possible use the typed API in order to directly get a handle to
your asset. If you do not know the type or need to use `load_untyped`
for a different reason, Bevy 0.12 introduces an additional layer of
indirection. The asset server will return a handle to a
`LoadedUntypedAsset`, which will load in the background. Once it is
loaded, the untyped handle to the asset file can be retrieved from the
`LoadedUntypedAsset`s field `handle`.

# Objective
Fixes#9395
Alternative to #9415 (See discussion here)
## Solution
Do clamping like
[`fit-content`](https://www.w3.org/TR/css-sizing-3/#column-sizing).
## Notes
I am not sure if this is a valid approach. It doesn't seem to cause any
obvious issues with our existing examples.
# Objective
- Hot reloading doesn't work the first time it is used
## Solution
- Currently, Bevy processor:
1. Create the `imported_assets` folder
2. Setup a watcher on it
3. Clear empty folders, so the `imported_assets` folder is deleted
4. Recreate the `imported_assets` folder and add all the imported assets
- On a first run without an existing `imported_assets` with some
content, hot reloading won't work as step 3 breaks the file watcher
- This PR stops the empty root folder from being deleted
- Also don't setup the processor internal asset server for file
watching, freeing up a thread

# Objective
First of all, this PR took heavy inspiration from #7760 and #5715. It
intends to also fix#5569, but with a slightly different approach.
This also fixes#9335 by reexporting `DynEq`.
## Solution
The advantage of this API is that we can intern a value without
allocating for zero-sized-types and for enum variants that have no
fields. This PR does this automatically in the `SystemSet` and
`ScheduleLabel` derive macros for unit structs and fieldless enum
variants. So this should cover many internal and external use cases of
`SystemSet` and `ScheduleLabel`. In these optimal use cases, no memory
will be allocated.
- The interning returns a `Interned<dyn SystemSet>`, which is just a
wrapper around a `&'static dyn SystemSet`.
- `Hash` and `Eq` are implemented in terms of the pointer value of the
reference, similar to my first approach of anonymous system sets in
#7676.
- Therefore, `Interned<T>` does not implement `Borrow<T>`, only `Deref`.
- The debug output of `Interned<T>` is the same as the interned value.
Edit:
- `AppLabel` is now also interned and the old
`derive_label`/`define_label` macros were replaced with the new
interning implementation.
- Anonymous set ids are reused for different `Schedule`s, reducing the
amount of leaked memory.
### Pros
- `InternedSystemSet` and `InternedScheduleLabel` behave very similar to
the current `BoxedSystemSet` and `BoxedScheduleLabel`, but can be copied
without an allocation.
- Many use cases don't allocate at all.
- Very fast lookups and comparisons when using `InternedSystemSet` and
`InternedScheduleLabel`.
- The `intern` module might be usable in other areas.
- `Interned{ScheduleLabel, SystemSet, AppLabel}` does implement
`{ScheduleLabel, SystemSet, AppLabel}`, increasing ergonomics.
### Cons
- Implementors of `SystemSet` and `ScheduleLabel` still need to
implement `Hash` and `Eq` (and `Clone`) for it to work.
## Changelog
### Added
- Added `intern` module to `bevy_utils`.
- Added reexports of `DynEq` to `bevy_ecs` and `bevy_app`.
### Changed
- Replaced `BoxedSystemSet` and `BoxedScheduleLabel` with
`InternedSystemSet` and `InternedScheduleLabel`.
- Replaced `impl AsRef<dyn ScheduleLabel>` with `impl ScheduleLabel`.
- Replaced `AppLabelId` with `InternedAppLabel`.
- Changed `AppLabel` to use `Debug` for error messages.
- Changed `AppLabel` to use interning.
- Changed `define_label`/`derive_label` to use interning.
- Replaced `define_boxed_label`/`derive_boxed_label` with
`define_label`/`derive_label`.
- Changed anonymous set ids to be only unique inside a schedule, not
globally.
- Made interned label types implement their label trait.
### Removed
- Removed `define_boxed_label` and `derive_boxed_label`.
## Migration guide
- Replace `BoxedScheduleLabel` and `Box<dyn ScheduleLabel>` with
`InternedScheduleLabel` or `Interned<dyn ScheduleLabel>`.
- Replace `BoxedSystemSet` and `Box<dyn SystemSet>` with
`InternedSystemSet` or `Interned<dyn SystemSet>`.
- Replace `AppLabelId` with `InternedAppLabel` or `Interned<dyn
AppLabel>`.
- Types manually implementing `ScheduleLabel`, `AppLabel` or `SystemSet`
need to implement:
- `dyn_hash` directly instead of implementing `DynHash`
- `as_dyn_eq`
- Pass labels to `World::try_schedule_scope`, `World::schedule_scope`,
`World::try_run_schedule`. `World::run_schedule`, `Schedules::remove`,
`Schedules::remove_entry`, `Schedules::contains`, `Schedules::get` and
`Schedules::get_mut` by value instead of by reference.

# Objective
When a mesh vertex attribute has a vertex count mismatch, a warning
message is printed with the index of the attribute which did not match.
Change to name the attribute, or fall back to the old behaviour if it
was not a known attribute.
Before:
```
MeshVertexAttributeId(2) has a different vertex count (32) than other attributes (64) in this mesh, all attributes will be truncated to match the smallest.
```
After:
```
Vertex_Uv has a different vertex count (32) than other attributes (64) in this mesh, all attributes will be truncated to match the smallest.
```
## Solution
Name the mesh attribute which had a count mismatch.
## Changelog
- If a mesh vertex attribute has a different count than other vertex
attributes, name the offending attribute using a human readable name

# Objective
- the style of import used by bevy guarantees merge conflicts when any
file change
- This is especially true when import lists are large, such as in
`bevy_pbr`
- Merge conflicts are tricky to resolve. This bogs down rendering PRs
and makes contributing to bevy's rendering system more difficult than it
needs to
## Solution
- Use wildcard imports to replace multiline import list in `bevy_pbr`
I suspect this is controversial, but I'd like to hear alternatives.
Because this is one of many papercuts that makes developing render
features near impossible.
Closes#9946
# Objective
Add a new type mirroring `wgpu::SamplerDescriptor` for
`ImageLoaderSettings` to control how a loaded image should be sampled.
Fix issues with texture sampler descriptors not being set when loading
gltf texture from URI.
## Solution
Add a new `ImageSamplerDescriptor` and its affiliated types that mirrors
`wgpu::SamplerDescriptor`, use it in the image loader settings.
---
## Changelog
### Added
- Added new types `ImageSamplerDescriptor`, `ImageAddressMode`,
`ImageFilterMode`, `ImageCompareFunction` and `ImageSamplerBorderColor`
that mirrors the corresponding wgpu types.
- `ImageLoaderSettings` now carries an `ImageSamplerDescriptor` field
that will be used to determine how the loaded image is sampled, and will
be serialized as part of the image assets `.meta` files.
### Changed
- `Image::from_buffer` now takes the sampler descriptor to use as an
additional parameter.
### Fixed
- Sampler descriptors are set for gltf textures loaded from URI.

## Solution
- Fix the import path
The "gray" issue is since #9258 on macOS
... at least they're not white anymore

# Objective
A follow-up PR for https://github.com/bevyengine/bevy/pull/10221
## Changelog
Replaced usages of texture_descriptor.size with the helper methods of
`Image` through the entire engine codebase
# Objective
Reduce code duplication and improve APIs of Bevy's [global
taskpools](https://github.com/bevyengine/bevy/blob/main/crates/bevy_tasks/src/usages.rs).
## Solution
- As all three of the global taskpools have identical implementations
and only differ in their identifiers, this PR moves the implementation
into a macro to reduce code duplication.
- The `init` method is renamed to `get_or_init` to more accurately
reflect what it really does.
- Add a new `try_get` method that just returns `None` when the pool is
uninitialized, to complement the other getter methods.
- Minor documentation improvements to accompany the above changes.
---
## Changelog
- Added a new `try_get` method to the global TaskPools
- The global TaskPools' `init` method has been renamed to `get_or_init`
for clarity
- Documentation improvements
## Migration Guide
- Uses of `ComputeTaskPool::init`, `AsyncComputeTaskPool::init` and
`IoTaskPool::init` should be changed to `::get_or_init`.
# Objective
- Handle pausing audio when Android app is suspended
## Solution
- This is the start of application lifetime events. They are mostly
useful on mobile
- Next version of winit should add a few more
- When application is suspended, send an event to notify the
application, and run the schedule one last time before actually
suspending the app
- Audio is now suspended too 🎉https://github.com/bevyengine/bevy/assets/8672791/d74e2e09-ee29-4f40-adf2-36a0c064f94e

# Objective
Fog color was passed to shaders without conversion from sRGB to linear
color space. Because shaders expect colors in linear space this resulted
in wrong color being used. This is most noticeable in open scenes with
dark fog color and clear color set to the same color. In such case
background/clear color (which is properly processed) is going to be
darker than very far objects.
Example:
[bevy-fog-color-bug.zip](https://github.com/bevyengine/bevy/files/13063718/bevy-fog-color-bug.zip)
## Solution
Add missing conversion of fog color to linear color space.
---
## Changelog
* Fixed conversion of fog color
## Migration Guide
- Colors in `FogSettings` struct (`color` and `directional_light_color`)
are now sent to the GPU in linear space. If you were using
`Color::rgb()`/`Color::rgba()` and would like to retain the previous
colors, you can quickly fix it by switching to
`Color::rgb_linear()`/`Color::rgba_linear()`.
# Objective
- After #9826, there are issues on "run once runners"
- example `without_winit` crashes:

Unable to get RenderApp. Another plugin may have removed the RenderApp before PipelinedRenderingPlugin
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
- example `headless` runs the app twice with the `run_once` schedule
## Solution
- Expose a more complex state of an app than just "ready"
- Also block adding plugins to an app after it has finished or cleaned
up its plugins as that wouldn't work anyway
## Migration Guide
* `app.ready()` has been replaced by `app.plugins_state()` which will
return more details on the current state of plugins in the app
