# 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
[0..1] x [0..1] space defined by another rectangle.
Useful for UI and texture atlas calculations etc.

# Objective
- 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
Fixes#9473
## Solution
Added `resolve()` method to AssetPath. This method accepts a relative
asset path string and returns a "full" path that has been resolved
relative to the current (self) path.

# 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
- Reduce noise to allow users to see previous asset changes and other
logs like from asset reloading
- The example file is named differently than the example
## Solution
- Only print the asset content if there are asset events
- Rename the example file to `asset_processing`
# 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.
# Objective
- Fixes#10250

# 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:

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
# Objective
- Replace md5 by another hasher, as suggested in
https://github.com/bevyengine/bevy/pull/8624#discussion_r1359291028
- md5 is not secure, and is slow. use something more secure and faster
## Solution
- Replace md5 by blake3
Putting this PR in the 0.12 as once it's released, changing the hash
algorithm will be a painful breaking change
# Objective
Even at `reflectance == 0.0`, our ambient and environment map light
implementations still produce fresnel/specular highlights.
Such a low `reflectance` value lies outside of the physically possible
range and is already used by our directional, point and spot light
implementations (via the `fresnel()` function) to enable artistic
control, effectively disabling the fresnel "look" for non-physically
realistic materials. Since ambient and environment lights use a
different formulation, they were not honoring this same principle.
This PR aims to bring consistency to all light types, offering the same
fresnel extinguishing control to ambient and environment lights.
Thanks to `@nathanf` for [pointing
out](https://discord.com/channels/691052431525675048/743663924229963868/1164083373514440744)
the [Filament docs section about
this](https://google.github.io/filament/Filament.md.html#lighting/occlusion/specularocclusion).
## Solution
- We use [the same
formulation](ffc572728f/crates/bevy_pbr/src/render/pbr_lighting.wgsl (L99))
already used by the `fresnel()` function in `bevy_pbr::lighting` to
modulate the F90, to modulate the specular component of Ambient and
Environment Map lights.
## Comparison
⚠️ **Modified version of the PBR example for demo purposes, that shows
reflectance (_NOT_ part of this PR)** ⚠️
Also, keep in mind this is a very subtle difference (look for the
fresnel highlights on the lower left spheres, you might need to zoom in.

## Changelog
- Ambient and Environment Map lights will now honor values of
`reflectance` that are below the physically possible range (⪅ 0.35) by
extinguishing their fresnel highlights. (Just like point, directional
and spot lights already did.) This allows for more consistent artistic
control and for non-physically realistic looks with all light types.
## Migration Guide
- If Fresnel highlights from Ambient and Environment Map lights are no
longer visible in your materials, make sure you're using a higher,
physically plausible value of `reflectance` (⪆ 0.35).
# Objective
- I want to use the `debug_glam_assert` feature with bevy.
## Solution
- Re-export the feature flag
---
## Changelog
- Re-export `debug_glam_assert` feature flag from glam.
# Objective
Fixes#5101
Alternative to #6511
## Solution
Corrected the behavior for ignored fields in `FromReflect`, which was
previously using the incorrect field indexes.
Similarly, fields marked with `#[reflect(skip_serializing)]` no longer
break when using `FromReflect` after deserialization. This was done by
modifying `SerializationData` to store a function pointer that can later
be used to generate a default instance of the skipped field during
deserialization.
The function pointer points to a function generated by the derive macro
using the behavior designated by `#[reflect(default)]` (or just
`Default` if none provided). The entire output of the macro is now
wrapped in an [unnamed
constant](https://doc.rust-lang.org/stable/reference/items/constant-items.html#unnamed-constant)
which keeps this behavior hygienic.
#### Rationale
The biggest downside to this approach is that it requires fields marked
`#[reflect(skip_serializing)]` to provide the ability to create a
default instance— either via a `Default` impl or by specifying a custom
one. While this isn't great, I think it might be justified by the fact
that we really need to create this value when using `FromReflect` on a
deserialized object. And we need to do this _during_ deserialization
because after that (at least for tuples and tuple structs) we lose
information about which field is which: _"is the value at index 1 in
this `DynamicTupleStruct` the actual value for index 1 or is it really
the value for index 2 since index 1 is skippable...?"_
#### Alternatives
An alternative would be to store `Option<Box<dyn Reflect>>` within
`DynamicTuple` and `DynamicTupleStruct` instead of just `Box<dyn
Reflect>`. This would allow us to insert "empty"/"missing" fields during
deserialization, thus saving the positional information of the skipped
fields. However, this may require changing the API of `Tuple` and
`TupleStruct` such that they can account for their dynamic counterparts
returning `None` for a skipped field. In practice this would probably
mean exposing the `Option`-ness of the dynamics onto implementors via
methods like `Tuple::drain` or `TupleStruct::field`.
Personally, I think requiring `Default` would be better than muddying up
the API to account for these special cases. But I'm open to trying out
this other approach if the community feels that it's better.

## Changelog
### Public Changes
#### Fixed
- The behaviors of `#[reflect(ignore)]` and
`#[reflect(skip_serializing)]` are no longer dependent on field order
#### Changed
- Fields marked with `#[reflect(skip_serializing)]` now need to either
implement `Default` or specify a custom default function using
`#[reflect(default = "path::to::some_func")]`
- Deserializing a type with fields marked `#[reflect(skip_serializing)]`
will now include that field initialized to its specified default value
- `SerializationData::new` now takes the new `SkippedField` struct along
with the skipped field index
- Renamed `SerializationData::is_ignored_field` to
`SerializationData::is_field_skipped`
#### Added
- Added `SkippedField` struct
- Added methods `SerializationData::generate_default` and
`SerializationData::iter_skipped`
### Internal Changes
#### Changed
- Replaced `members_to_serialization_denylist` and `BitSet<u32>` with
`SerializationDataDef`
- The `Reflect` derive is more hygienic as it now outputs within an
[unnamed
constant](https://doc.rust-lang.org/stable/reference/items/constant-items.html#unnamed-constant)
- `StructField::index` has been split up into
`StructField::declaration_index` and `StructField::reflection_index`
#### Removed
- Removed `bitset` dependency
## Migration Guide
* Fields marked `#[reflect(skip_serializing)]` now must implement
`Default` or specify a custom default function with `#[reflect(default =
"path::to::some_func")]`
```rust
#[derive(Reflect)]
struct MyStruct {
#[reflect(skip_serializing)]
#[reflect(default = "get_foo_default")]
foo: Foo, // <- `Foo` does not impl `Default` so requires a custom
function
#[reflect(skip_serializing)]
bar: Bar, // <- `Bar` impls `Default`
}
#[derive(Reflect)]
struct Foo(i32);
#[derive(Reflect, Default)]
struct Bar(i32);
fn get_foo_default() -> Foo {
Foo(123)
}
```
* `SerializationData::new` has been changed to expect an iterator of
`(usize, SkippedField)` rather than one of just `usize`
```rust
// BEFORE
SerializationData::new([0, 3].into_iter());
// AFTER
SerializationData::new([
(0, SkippedField::new(field_0_default_fn)),
(3, SkippedField::new(field_3_default_fn)),
].into_iter());
```
* `Serialization::is_ignored_field` has been renamed to
`Serialization::is_field_skipped`
* Fields marked `#[reflect(skip_serializing)]` are now included in
deserialization output. This may affect logic that expected those fields
to be absent.
# Objective
To get the width or height of an image you do:
```rust
self.texture_descriptor.size.{width, height}
```
that is quite verbose.
This PR adds some convenient methods for Image to reduce verbosity.
## Changelog
* Add a `width()` method for getting the width of an image.
* Add a `height()` method for getting the height of an image.
* Rename the `size()` method to `size_f32()`.
* Add a `size()` method for getting the size of an image as u32.
* Renamed the `aspect_2d()` method to `aspect_ratio()`.
## Migration Guide
Replace calls to the `Image::size()` method with `size_f32()`.
Replace calls to the `Image::aspect_2d()` method with `aspect_ratio()`.
