# Objective
- Fixes#14796
## Solution
- Copy docs for wrapper methods, make sure they are consistent with the
original docs except for the section on precision.
# Objective
It looks like running `compile_fail_utils::test` on an invalid path just
skips the test. I'm not sure why `ui_test` doesn't fail the test, but it
seems pretty easy to accidentally cause a test to be skipped (I
experienced
[this](https://github.com/bevyengine/bevy/pull/14813#discussion_r1721880973)
while doing some refactoring on `bevy_reflect`).
## Solution
Check to make sure the given path exists before continuing on with the
tests.
Alternatively, we could look into seeing why this doesn't work properly
upstream. But I figured this solution was simple enough just to
implement directly without having to worry about updating `ui_test`.
## Testing
To verify that this works as expected `cd` into
`crates/bevy_reflect/compile_fail`. Then run the following:
```
cargo test --target-dir ../../../target
```
All compile fail tests should pass. Now edit the path used in
`crates/bevy_reflect/compile_fail/tests/derive.rs`. For example:
```diff
fn main() -> compile_fail_utils::ui_test::Result<()> {
- compile_fail_utils::test("reflect_derive", "tests/reflect_derive")
+ compile_fail_utils::test("reflect_derive", "tests/does_not_exist")
}
```
Run the tests again:
```
cargo test --target-dir ../../../target
```
Verify the test fails with an error like:
```
Error: path does not exist: "tests/does_not_exist"
```
# Objective
Make the naming of a parameter more consistent.
## Solution
- Changing the name of a parameter.
## Testing
These changes can't be tested as they are documentation based.

I apologize if something is wrong here, this is my first PR to bevy.
# Objective
`RenderLayers` was marketed as being unlimited in the Bevy 0.14 release
notes, but the most obvious constructor doesn't actually support
unlimited layers.
We should explicitly document this.
## Solution
Add some docs mentioning the limit and pointing the user to `with` or
`from_layers` if they need an arbitrary number of layers.
# Objective
Fixes#14782
## Solution
Enable the lint and fix all upcoming hints (`--fix`). Also tried to
figure out the false-positive (see review comment). Maybe split this PR
up into multiple parts where only the last one enables the lint, so some
can already be merged resulting in less many files touched / less
potential for merge conflicts?
Currently, there are some cases where it might be easier to read the
code with the qualifier, so perhaps remove the import of it and adapt
its cases? In the current stage it's just a plain adoption of the
suggestions in order to have a base to discuss.
## Testing
`cargo clippy` and `cargo run -p ci` are happy.
# Objective
add a quick shorthand for creating a sprite with an custom size. This is
often desired when working with custom units or scaled sprites and
allows for a cleaner syntax in those cases/
## Solution
Implemented a `sized` function on the Sprite struct which creates a
Sprite, sets the custom size and leaves the rest at their default values
---
## Changelog
- Added `Sprite::sized(custom_size: Vec2)`
# Objective
currently if we use an image with the wrong sampler type in a material,
wgpu panics with an invalid texture format. turn this into a warning and
fail more gracefully.
## Solution
the expected sampler type is specified in the AsBindGroup derive, so we
can just check the image sampler is what it should be.
i am not totally sure about the mapping of image sampler type to
#[sampler(type)], i assumed:
```
"filtering" => [ TextureSampleType::Float { filterable: true } ],
"non_filtering" => [
TextureSampleType::Float { filterable: false },
TextureSampleType::Sint,
TextureSampleType::Uint,
],
"comparison" => [ TextureSampleType::Depth ],
```
# Objective
- Fixes#14684
## Solution
- Added documentation to `all_tuples_with_size` based on existing
`all_tuples` documentation.
- Updated `all_tuples` documentation to match formatting of and link
back to `all_tuples_with_size`
## Testing
- Doctests ran locally.
## Notes
Formatting changes I have proposed make the documentation a little
cleaner in my opinion, but I am open to reverting them and amending
`all_tuples_with_size` to match if there are any reasonable objections.
This reverts commit e37bf18e2b, added in
#14784.
# Objective
The PR was fine, but the work was very poorly motivated and the
resulting API is not actually very nice. The actual user need is likely
better addressed by #14825.
## Solution
Revert the offending PR.
Fix `mesh2d_manual` example from changes in #13069.
```
wgpu error: Validation Error

```
# Objective
- Fixes#10478
## Solution
Generalised `From/Into` implementations over `&str` and `Option<&str>`
for `AssetSourceId` and `AssetPath` across all lifetimes, not just
static. To maintain access to the `'static`-only specialisation, these
types (and `CowArc`) now include an `as_static` method which will apply
the specialisation.
```rust
// Snipped from `AssetApp`
fn register_asset_source(
&mut self,
id: impl Into<AssetSourceId<'static>>,
// ^^^^^^^
// | as_static is only available for 'static lifetimes
source: AssetSourceBuilder,
) -> &mut Self {
let id = id.into().as_static();
// ^^^^^^ ^^^^^^^^^
// | | Specialized (internally storing CowArc::Static)
// | Generic Into (internally storing CowArc::Borrowed)
// ...
}
```
This post-fix specialisation is available here because the actual
specialisation performed is only a marker for if/when modification or
ownership is required, making the transform a very cheap operation. For
cleanliness, I've also added `from_static`, which wraps this behaviour
in a clean shorthand designed to replace `from` calls.
---
## Changelog
- Generalised the following implementations over a generic lifetime:
- `From<&'static str> for AssetSourceId<'static>`
- `From<Option<&'static str>> for AssetSourceId<'static>`
- `From<&'static str> for AssetPath<'static>`
- `From<&'static Path> for AssetPath<'static>`
- Added `as_static` specialisation to:
- `CowArc`
- `AssetSourceId`
- `AssetPath`
- Added `from_static` specialised constructor to:
- `AssetSourceId`
- `AssetPath`
## Migration Guide
In areas where these implementations where being used, you can now add
`from_static` in order to get the original specialised implementation
which avoids creating an `Arc` internally.
```rust
// Before
let asset_path = AssetPath::from("my/path/to/an/asset.ext");
// After
let asset_path = AssetPath::from_static("my/path/to/an/asset.ext");
```
To be clear, this is only required if you wish to maintain the
performance benefit that came with the specialisation. Existing code is
_not_ broken by this change.
# Objective
The `target` directory in `/tools/compile_fail_utils` was not being
ignored by Git.
## Solution
Added `/tools/compile_fail_utils/target` to the root `.gitignore` in the
same spirit as the other top-level, workspace-excluded crate: `benches`.
# Objective
One of the changes in #14704 made `DynamicFunction` effectively the same
as `DynamicClosure<'static>`. This change meant that the de facto
function type would likely be `DynamicClosure<'static>` instead of the
intended `DynamicFunction`, since the former is much more flexible.
We _could_ explore ways of making `DynamicFunction` implement `Copy`
using some unsafe code, but it likely wouldn't be worth it. And users
would likely still reach for the convenience of
`DynamicClosure<'static>` over the copy-ability of `DynamicFunction`.
The goal of this PR is to fix this confusion between the two types.
## Solution
Firstly, the `DynamicFunction` type was removed. Again, it was no
different than `DynamicClosure<'static>` so it wasn't a huge deal to
remove.
Secondly, `DynamicClosure<'env>` and `DynamicClosureMut<'env>` were
renamed to `DynamicFunction<'env>` and `DynamicFunctionMut<'env>`,
respectively.
Yes, we still ultimately kept the naming of `DynamicFunction`, but
changed its behavior to that of `DynamicClosure<'env>`. We need a term
to refer to both functions and closures, and "function" was the best
option.
[Originally](https://discord.com/channels/691052431525675048/1002362493634629796/1274091992162242710),
I was going to go with "callable" as the replacement term to encompass
both functions and closures (e.g. `DynamciCallable<'env>`). However, it
was
[suggested](https://discord.com/channels/691052431525675048/1002362493634629796/1274653581777047625)
by @SkiFire13 that the simpler "function" term could be used instead.
While "callable" is perhaps the better umbrella term—being truly
ambiguous over functions and closures— "function" is more familiar, used
more often, easier to discover, and is subjectively just
"better-sounding".
## Testing
Most changes are purely swapping type names or updating documentation,
but you can verify everything still works by running the following
command:
```
cargo test --package bevy_reflect
```
# Objective
currently if an asset loader panics, the asset is left in a perpetual
`Loading` state. this can occur with external crates (eg the image crate
panics on bad data). catch this panic and resolve the asset to `Failed`

`AssertUnwindSafe(loader.load).catch_unwind()` and map the panic to an
`AssetLoadError`

# Objective
While looking through the changes #14782 will create I noticed this.
## Solution
Reuse the existing thread_rng. As this is a code change I would like to
not include it in a pure lint enable PR.
## Testing
I did not test this change (other than the automated CI with this PR). I
think it should be a fairly simple change that can be reviewed only by
the code.
# Objective
Delete some code that isn't actually doing anything. This was actually
discovered way back in this obsolete PR: #5513.
Also Fixes#6286
## Solution
Delete it
## Alternatives
Make `Direction` do things. But it's not totally clear to me if it's
possible to override cosmic-text's unicode bidi stuff.
## Migration Guide
`Style` no longer has a `direction` field, and `Direction` has been
deleted. They didn't do anything, so you can delete any references to
them as well.
# Objective
Fixes#14521.
## Solution
Added to methods to the VIsibility.
```rs
is_visible() -> Result<bool, String>
```
and
```rs
visbility_from_bool(bool) -> Visibility
```
## Testing
Ran
* `cargo run -p ci -- lints`
* `cargo run -p ci -- test`
* `cargo run -p ci -- compile`
it seems to be working.
However I got few error messages :`ERROR bevy_log: could not set global
logger and tracing subscriber as they are already set. Consider
disabling LogPlugin` in `cargo run -p ci -- test`, even though all test
passed. I'm not sure if that's expected behaviour
Ps. I'm new to contributing, please correct me if anything is wrong
# Objective
Some algorithms don't really work well or are not efficient in 3D space.
When we know we have points on an `InfinitePlane3d` it would be helpful
to have some utility methods to reversibly transform points on the plane
to 2D space to apply some algorithms there.
## Solution
This PR adds a few of methods to project 3D points on a plane to 2D
points and inject them back. Additionally there are some other small
common helper methods.
## Testing
- added some tests that cover the new methods

Fixes Commands not being `Send` or `Sync` anymore in 0.14 by
implementing `Send` and `Sync` for `RawCommandQueue`.
## Solution
Reference discussion in
[discord](https://discord.com/channels/691052431525675048/691052431974465548/1259464518539411570).
It seems that in https://github.com/bevyengine/bevy/pull/13249, when
adding a `RawCommandQueue` variant to the `InternalQueue`, the `Send /
Sync` traits were not implemented for it, which bubbled up all the way
to `Commands` not being `Send / Sync` anymore.
I am not very familiar with the ECS internals so I can't say whether the
`RawCommandQueue` is safe to be shared between threads, but I know for
sure that before the linked PR `Commands` were indeed `Send` and `Sync`
so that PR broke "some workflows" (mandatory
[xkcd](https://xkcd.com/1172/)).
## Testing
This PR itself includes a compile test to make sure `Commands` will
implement `Send` and `Sync`. The test itself fails without the
implementation and succeeds with it.
Furthermore, if I cherry pick the test to a previous release (i.e. 0.13)
it indeed succeeds, showing that this is a regression specific to 0.14.

# Objective
`MeshVertexAttributeId` is currently a wrapper type around a `usize`.
Application developers are exposed to the `usize` whenever they need to
define a new custom vertex attribute, which requires them to generate a
random `usize` ID to avoid clashes with any other custom vertex
attributes in the same application. As the range of a `usize` is
platform dependent, developers on 64-bit machines may inadvertently
generate random values which will fail to compile for a 32-bit target.
The use of a `usize` here encourages non-portable behaviour and should
be replaced with a fixed width type.
## Solution
In this PR I have changed the ID type from `usize` to `u64`, but equally
a `u32` could be used at the risk of breaking some extant non-portable
programs and increasing the chance of an ID collision.
# Objective
Fixes#14811
## Solution
- Switch `D` to `T`: `T` for "on top of"
- Switch `A` to `B`: `B` in "AABB", or "boxes"

- Checked the key bindings that the camera controller uses and made sure
we're not using them in the 3d_gizmos example anymore

# Objective
#14098 added the `FunctionRegistry` for registering functions such that
they can be retrieved by name and used dynamically. One thing we chose
to leave out in that initial PR is support for closures.
Why support closures? Mainly, we don't want to prohibit users from
injecting environmental data into their registered functions. This
allows these functions to not leak their internals to the public API.
For example, let's say we're writing a library crate that allows users
to register callbacks for certain actions. We want to perform some
actions before invoking the user's callback so we can't just call it
directly. We need a closure for this:
```rust
registry.register("my_lib::onclick", move |event: ClickEvent| {
// ...other work...
user_onclick.call(event); // <-- Captured variable
});
```
We could have made our callback take a reference to the user's callback.
This would remove the need for the closure, but it would change our
desired API to place the burden of fetching the correct callback on the
caller.
## Solution
Modify the `FunctionRegistry` to store registered functions as
`DynamicClosure<'static>` instead of `DynamicFunction` (now using
`IntoClosure` instead of `IntoFunction`).
Due to limitations in Rust and how function reflection works,
`DynamicClosure<'static>` is functionally equivalent to
`DynamicFunction`. And a normal function is considered a subset of
closures (it's a closure that doesn't capture anything), so there
shouldn't be any difference in usage: all functions that satisfy
`IntoFunction` should satisfy `IntoClosure`.
This means that the registration API introduced in #14098 should require
little-to-no changes on anyone following `main`.
### Closures vs Functions
One consideration here is whether we should keep closures and functions
separate.
This PR unifies them into `DynamicClosure<'static>`, but we can consider
splitting them up. The reasons we might want to do so are:
- Simplifies mental model and terminology (users don't have to
understand that functions turn into closures)
- If Rust ever improves its function model, we may be able to add
additional guarantees to `DynamicFunction` that make it useful to
separate the two
- Adding support for generic functions may be less confusing for users
since closures in Rust technically can't be generic
The reasons behind this PR's unification approach are:
- Reduces the number of methods needed on `FunctionRegistry`
- Reduces the number of lookups a user may have to perform (i.e.
"`get_function` or else `get_closure`")
- Establishes `DynamicClosure<'static>` as the de facto dynamic callable
(similar to how most APIs in Rust code tend to prefer `impl Fn() ->
String` over `fn() -> String`)
I'd love to hear feedback on this matter, and whether we should continue
with this PR's approach or switch to a split model.
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect
```
---
## Showcase
Closures can now be registered into the `FunctionRegistry`:
```rust
let punct = String::from("!!!");
registry.register_with_name("my_crate::punctuate", move |text: String| {
format!("{}{}", text, punct)
});
```
# Objective
The `prepare_view_upscaling_pipelines` system has dozens of ambiguities,
which makes it harder to spot and prevent new ambiguities.
Closes https://github.com/bevyengine/bevy/issues/14770.
## Solution
Just exclude the system from ambiguity detection. See the linked issue
for more context on why this resolution was chosen.
## Testing
Running the `ambiguity_detection` example now reports dozens fewer
`Render` app ambiguities.
# Objective
- Add "Available on crate feature <image format> only." for docs of
image format related types/functions
- Add warning "WARN bevy_render::texture::image: feature "<image
format>" is not enabled" on load attempt
- Fixes#13468 .
## Solution
- Added #[cfg(feature = "<image format>")] for types and warn!("feature
\"<image format>\" is not enabled"); for ImageFormat enum conversions
## Testing
ran reproducing example from issue #13468 and saw in logs
`WARN bevy_render::texture::image: feature "exr" is not enabled`
generated docs with command `RUSTDOCFLAGS="-Zunstable-options
--cfg=docsrs" cargo +nightly doc --workspace --all-features --no-deps
--document-private-items --open` and saw
that docs contain `Available on crate feature <image format> only.`
marks
## Migration Guide
Image format related entities are feature gated, if there are
compilation errors about unknown names there are some of features in
list (`exr`, `hdr`, `basis-universal`, `png`, `dds`, `tga`, `jpeg`,
`bmp`, `ktx2`, `webp` and `pnm`) should be added.
# Objective
- Fixes#14655
## Solution
Rotation should happen first as this is more easier to conceptualize in
the mind: We rotate around the coordinate origin `Vec3::ZERO` and then
we just shift the geometry so that its center is exactly on the
specified position
## Testing && Showcase
Code:
```rust
gizmos.grid(
Vec3::ONE * 10.0,
Quat::from_rotation_x(PI / 3. * 2.),
UVec2::splat(20),
Vec2::new(2., 2.),
PURPLE,
);
gizmos.sphere(Vec3::ONE * 10.0, Quat::default(), 1.0, PURPLE);
```

## Migration Guide
- Users might have to double check their already existing calls to all
the `grid` methods. It should be more intuitive now though.
# Objective
Fix#14771 by adding a `try_insert_if_new` method to the
`EntityCommands`
## Solution
This simply calls the `try_insert` function with `InsertMode::Keep`
## Testing
I did not add any test because `EntityCommands::try_insert` does not
seem to be tested either. I can add some if needed.
# Objective
Fixes#14736
## Solution
Enables feature `bevy_render` for dependency `bevy_gizmos` in
`bevy_dev_tools` cargo.
`bevy_dev_tools` has `bevy_render` as a required dependency, whereas it
is optional for `bevy_gizmos`. When building with no default features,
this causes gizmos to not compile with `bevy_render` features, meaning
some fields and code are not available. Since these features are
required in dev tools, it makes sense to ensure they are enabled. Making
`bevy_render` optional would introduce additional and potentially
unwanted change wake. in dev tools.
## Testing
Reproed and tested on Windows 10, issue originally reported on Ubuntu
and MacOS.
- Original issue command completed without error: `cargo c -p bevy
--no-default-features -F bevy_dev_tools`
- Ran full ci validations with `cargo run -p ci`
# Objective
Finish what we started in #14630. The Curve RFC is
[here](https://github.com/bevyengine/rfcs/blob/main/rfcs/80-curve-trait.md).
## Solution
This contains the rest of the library from my branch. The main things
added here are:
- Bulk sampling / resampling methods on `Curve` itself
- Data structures supporting the above
- The `cores` submodule that those data structures use to encapsulate
sample interpolation
The weirdest thing in here is probably `ChunkedUnevenCore` in `cores`,
which is not used by anything in the Curve library itself but which is
required for efficient storage of glTF animation curves. (See #13105.)
We can move it into a different PR if we want to; I don't have strong
feelings either way.
## Testing
New tests related to resampling are included. As I write this, I realize
we could use some tests in `cores` itself, so I will add some on this
branch before too long.

# Objective
- The [developer docs](https://dev-docs.bevyengine.org) are primarily
used by developers, who often deal with internal and private functions.
- @mweatherley suggested [on

that CI passes `--document-private-items` to the dev-docs, so
contributors can easily browse these internal details.
## Solution
- Add `--document-private-items` to the CI job that builds the dev-docs.
## Testing
- It should run in CI and generate documentation for private code.
## Drawbacks
- Users that track the main branch may use the dev-docs instead of
<https://docs.rs/bevy>, which may now show a lot of unwanted internal
details.
- Searching may be slower / bloated with internal details.
# Objective
fixes#14569
## Solution
added an example to the diagnostic examples and linked the code to the
docs of the diagnostic library itself.
## Testing
I tested locally on my laptop in a web browser. Looked fine. You are
able to collapse the whole "intro" part of the doc to get to the links
sooner (for those who may think that including the example code here is
annoying to scroll through)
I would like people to run ```cargo doc``` and go the bevy_diagnostic
page to see if they have any issues or suggestions.

# Objective
This `apply_deferred` doesn't seem to have any effect, pointlessly
restricts parallelism and is responsible for a large number of system
order ambiguities. Spotted as part of #7386.
## Solution
Remove it.
This is the *only* manual apply_deferred in the code base currently.
## Testing
I've checked various UI examples and `split_screen`, and couldn't
discern any difference.
This looks like a remnant of a `(a, apply_deferred, b).chain()` pattern
where `b` got removed, leaving us with a weird vestige.
# Objective
Often there are reasons to insert some components (e.g. Transform)
separately from the rest of a bundle (e.g. PbrBundle). However `insert`
overwrites existing components, making this difficult.
See also issue #14397Fixes#2054.
## Solution
This PR adds the method `insert_if_new` to EntityMut and Commands, which
is the same as `insert` except that the old component is kept in case of
conflicts.
It also renames some internal enums (from `ComponentStatus::Mutated` to
`Existing`), to reflect the possible change in meaning.
## Testing
*Did you test these changes? If so, how?*
Added basic unit tests; used the new behavior in my project.
*Are there any parts that need more testing?*
There should be a test that the change time isn't set if a component is
not overwritten; I wasn't sure how to write a test for that case.
*How can other people (reviewers) test your changes? Is there anything
specific they need to know?*
`cargo test` in the bevy_ecs project.
*If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?*
Only tested on Windows, but it doesn't touch anything platform-specific.

When an item in the transparent 2d phase fails to render, bevy crashes
with _"PassSpanScope::end was never called"_ instead of outputting the
actual error to the console. This PR fixes this so that phase errors are
output to the console. It also makes bevy not crash.

## Solution
Matched the behavior of the other render phases ([like
here](9ca5540b75/crates/bevy_core_pipeline/src/core_3d/main_opaque_pass_3d_node.rs (L98-L101)))
# Objective
While tackling https://github.com/bevyengine/bevy/issues/7386, I noticed
a few nits / frustrations with the existing testing infrastructure.
Rather than mixing those changes in with much more challenging to review
changes to reduce ambiguities, I've split this work into its own PR.
## Solution
Substantially simplify the `ambiguity_detection` test code, and reduce
the verbosity of logging.
## Testing
When run locally, the test functions as expected, with somewhat cleaner
logging.

# Objective
- Sometimes some method or function takes an owned `Query`, but we don't
want to give up ours;
- transmuting it technically a solution, but it more costly than
necessary.
- Make query iterators more flexible
- this would allow the equivalent of
`slice::split_first`/`slice::split_first_mut` for query iterators
- helps with requests like #14685
## Solution
- Add a way for reborrowing queries, that is going from a `&'a mut
Query<'w, 's, D, F>` to a `Query<'a, 's, D, F>`:
- this is safe because the original query will be borrowed while the new
query exists and thus no aliased access can happen;
- it's basically the equivalent of going from `&'short mut &'long mut T`
to `&'short mut T` the the compiler automatically implements.
- Add a way for getting the remainder of a query iterator:
- this is interesting also because the original iterator keeps its
position, which was not possible before;
- this in turn requires a way to reborrow query fetches, which I had to
add to `WorldQuery`.
## Showcase
- You can now reborrow a `Query`, getting an equivalent `Query` with a
shorter lifetime. Previously this was possible for read-only queries by
using `Query::to_readonly`, now it's possible for mutable queries too;
- You can now separately iterate over the remainder of `QueryIter`.
## Migration Guide
- `WorldQuery` now has an additional `shrink_fetch` method you have to
implement if you were implementing `WorldQuery` manually.
# Objective
`Res` and `ResMut` perform redundant lookups of the resource storage,
first to initialize the `ArchetypeComponentId` and then to retrieve it.
## Solution
Use the `archetype_component_id` returned from
`initialize_resource_internal` to avoid an extra lookup and `unwrap()`.
# Objective
fix#14742
## Solution
the issue arises because "finished" animations (where current time >=
last keyframe time) are not applied at all.
when transitioning from a finished animation to another later-indexed
anim, the transition kind-of works because the finished anim is skipped,
then the new anim is applied with a lower weight (weight / total_weight)
when transitioning from a finished animation to another earlier-indexed
anim, the transition is instant as the new anim is applied with 1.0 (as
weight == total_weight for the first applied), then the finished
animation is skipped.
to fix this we can always apply every animation based on the nearest 2
keyframes, and clamp the interpolation between them to [0,1].
pros:
- finished animations can be transitioned out of correctly
- blended animations where some curves have a last-keyframe before the
end of the animation will blend properly
- animations will actually finish on their last keyframe, rather than a
fraction of a render-frame before the end
cons:
- we have to re-apply finished animations every frame whether it's
necessary or not. i can't see a way to avoid this.
Makes the newly merged picking usable for UI elements.
currently it both triggers the events, as well as sends them as throught
commands.trigger_targets. We should probably figure out if this is
needed for them all.
# Objective
Hooks up obserers and picking for a very simple example
## Solution
upstreamed the UI picking backend from bevy_mod_picking
## Testing
tested with the new example picking/simple_picking.rs

# Objective
The code to create `ReflectComponent` and `ReflectResource` instances
manually constructs a `Mut<dyn Reflect>` by copying everything but
`value`. That can be done more concisely and better respecting
encapsulation by calling the `map_unchanged()` method.
## Solution
Use `map_unchanged` instead of creating a `Mut` manually.

# Objective
- Right now `DynamicEnum::is_dynamic()` is returning `false`. I don't
think this was expected, since the rest of `Dynamic*` types return
`true`.
## Solution
- Making `DynamicEnum::is_dynamic()` return true
## Testing
- Added an extra unit test to verify that `.is_dynamic()` returns
`true`.
# Objective
- Bevy now supports an opaque phase for mesh2d, but it's very common for
2d textures to have a transparent alpha channel.
## Solution
- Add an alpha mask phase identical to the one in 3d. It will do the
alpha masking in the shader before drawing the mesh.
- Uses the BinnedRenderPhase
- Since it's an opaque draw it also correctly writes to depth
## Testing
- Tested the mes2d_alpha_mode example and the bevymark example with
alpha mask mode enabled
---
## Showcase
The white logo on the right is rendered with alpha mask enabled.
Running the bevymark example I can get 65fps for 120k mesh2d all using
alpha mask.
## Notes
This is one more step for mesh2d improvements
