Fix rendering of sprites, text, and meshlets after #12582. (#12945)
`Sprite`, `Text`, and `Handle<MeshletMesh>` were types of renderable
entities that the new segregated visible entity system didn't handle, so
they didn't appear.

Because `bevy_text` depends on `bevy_sprite`, and the visibility
computation of text happens in the latter crate, I had to introduce a
new marker component, `SpriteSource`. `SpriteSource` marks entities that
aren't themselves sprites but become sprites during rendering. I added
this component to `Text2dBundle`. Unfortunately, this is technically a
breaking change, although I suspect it won't break anybody in practice
except perhaps editors.

Fixes #12935.

## Changelog

### Changed

* `Text2dBundle` now includes a new marker component, `SpriteSource`.
Bevy uses this internally to optimize visibility calculation.

## Migration Guide

* `Text` now requires a `SpriteSource` marker component in order to
appear. This component has been added to `Text2dBundle`.

Divide the single VisibleEntities list into separate lists for 2D meshes, 3D meshes, lights, and UI elements, for performance. (#12582)
This commit splits `VisibleEntities::entities` into four separate lists:
one for lights, one for 2D meshes, one for 3D meshes, and one for UI
elements. This allows `queue_material_meshes` and similar methods to
avoid examining entities that are obviously irrelevant. In particular,
this separation helps scenes with many skinned meshes, as the individual
bones are considered visible entities but have no rendered appearance.

Internally, `VisibleEntities::entities` is a `HashMap` from the `TypeId`
representing a `QueryFilter` to the appropriate `Entity` list. I had to
do this because `VisibleEntities` is located within an upstream crate
from the crates that provide lights (`bevy_pbr`) and 2D meshes
(`bevy_sprite`). As an added benefit, this setup allows apps to provide
their own types of renderable components, by simply adding a specialized
`check_visibility` to the schedule.

This provides a 16.23% end-to-end speedup on `many_foxes` with 10,000
foxes (24.06 ms/frame to 20.70 ms/frame).

## Migration guide

* `check_visibility` and `VisibleEntities` now store the four types of
renderable entities--2D meshes, 3D meshes, lights, and UI
elements--separately. If your custom rendering code examines
`VisibleEntities`, it will now need to specify which type of entity it's
interested in using the `WithMesh2d`, `WithMesh`, `WithLight`, and
`WithNode` types respectively. If your app introduces a new type of
renderable entity, you'll need to add an explicit call to
`check_visibility` to the schedule to accommodate your new component or
components.

Implement percentage-closer filtering (PCF) for point lights. (#12910)
I ported the two existing PCF techniques to the cubemap domain as best I
could. Generally, the technique is to create a 2D orthonormal basis
using Gram-Schmidt normalization, then apply the technique over that
basis. The results look fine, though the shadow bias often needs
adjusting.

For comparison, Unity uses a 4-tap pattern for PCF on point lights of
(1, 1, 1), (-1, -1, 1), (-1, 1, -1), (1, -1, -1). I tried this but
didn't like the look, so I went with the design above, which ports the
2D techniques to the 3D domain. There's surprisingly little material on
point light PCF.

I've gone through every example using point lights and verified that the
shadow maps look fine, adjusting biases as necessary.

Fixes #3628.

## Changelog

### Added
* Shadows from point lights now support percentage-closer filtering
(PCF), and as a result look less aliased.

### Changed
* `ShadowFilteringMethod::Castano13` and
`ShadowFilteringMethod::Jimenez14` have been renamed to
`ShadowFilteringMethod::Gaussian` and `ShadowFilteringMethod::Temporal`
respectively.

## Migration Guide

* `ShadowFilteringMethod::Castano13` and

Generate MeshUniforms on the GPU via compute shader where available. (#12773)
Currently, `MeshUniform`s are rather large: 160 bytes. They're also
somewhat expensive to compute, because they involve taking the inverse
of a 3x4 matrix. Finally, if a mesh is present in multiple views, that
mesh will have a separate `MeshUniform` for each and every view, which
is wasteful.

This commit fixes these issues by introducing the concept of a *mesh
input uniform* and adding a *mesh uniform building* compute shader pass.
The `MeshInputUniform` is simply the minimum amount of data needed for
the GPU to compute the full `MeshUniform`. Most of this data is just the
transform and is therefore only 64 bytes. `MeshInputUniform`s are
computed during the *extraction* phase, much like skins are today, in
order to avoid needlessly copying transforms around on CPU. (In fact,
the render app has been changed to only store the translation of each
mesh; it no longer cares about any other part of the transform, which is
stored only on the GPU and the main world.) Before rendering, the
`build_mesh_uniforms` pass runs to expand the `MeshInputUniform`s to the
full `MeshUniform`.

The mesh uniform building pass does the following, all on GPU:

1. Copy the appropriate fields of the `MeshInputUniform` to the
`MeshUniform` slot. If a single mesh is present in multiple views, this
effectively duplicates it into each view.

2. Compute the inverse transpose of the model transform, used for
transforming normals.

3. If applicable, copy the mesh's transform from the previous frame for
TAA. To support this, we double-buffer the `MeshInputUniform`s over two
frames and swap the buffers each frame. The `MeshInputUniform`s for the
current frame contain the index of that mesh's `MeshInputUniform` for
the previous frame.

This commit produces wins in virtually every CPU part of the pipeline:
`extract_meshes`, `queue_material_meshes`,
`batch_and_prepare_render_phase`, and especially
`write_batched_instance_buffer` are all faster. Shrinking the amount of
CPU data that has to be shuffled around speeds up the entire rendering
process.

| Benchmark              | This branch | `main`  | Speedup |
|------------------------|-------------|---------|---------|
| `many_cubes -nfc`      |      17.259 |  24.529 |  42.12% |
| `many_cubes -nfc -vpi` |     302.116 | 312.123 |   3.31% |
| `many_foxes`           |       3.227 |   3.515 |   8.92% |

Because mesh uniform building requires compute shader, and WebGL 2 has
no compute shader, the existing CPU mesh uniform building code has been
left as-is. Many types now have both CPU mesh uniform building and GPU
mesh uniform building modes. Developers can opt into the old CPU mesh
uniform building by setting the `use_gpu_uniform_builder` option on
`PbrPlugin` to `false`.

Below are graphs of the CPU portions of `many-cubes
--no-frustum-culling`. Yellow is this branch, red is `main`.

`extract_meshes`:
![Screenshot 2024-04-02
124842](https://github.com/bevyengine/bevy/assets/157897/a6748ea4-dd05-47b6-9254-45d07d33cb10)
It's notable that we get a small win even though we're now writing to a
GPU buffer.

`queue_material_meshes`:
![Screenshot 2024-04-02
124911](https://github.com/bevyengine/bevy/assets/157897/ecb44d78-65dc-448d-ba85-2de91aa2ad94)
There's a bit of a regression here; not sure what's causing it. In any
case it's very outweighed by the other gains.

`batch_and_prepare_render_phase`:
![Screenshot 2024-04-02
125123](https://github.com/bevyengine/bevy/assets/157897/4e20fc86-f9dd-4e5c-8623-837e4258f435)
There's a huge win here, enough to make batching basically drop off the
profile.

`write_batched_instance_buffer`:
![Screenshot 2024-04-02
125237](https://github.com/bevyengine/bevy/assets/157897/401a5c32-9dc1-4991-996d-eb1cac6014b2)
There's a massive improvement here, as expected. Note that a lot of it
simply comes from the fact that `MeshInputUniform` is `Pod`. (This isn't
a maintainability problem in my view because `MeshInputUniform` is so
simple: just 16 tightly-packed words.)

## Changelog

### Added

* Per-mesh instance data is now generated on GPU with a compute shader
instead of CPU, resulting in rendering performance improvements on
platforms where compute shaders are supported.

## Migration guide

* Custom render phases now need multiple systems beyond just
`batch_and_prepare_render_phase`. Code that was previously creating
custom render phases should now add a `BinnedRenderPhasePlugin` or
`SortedRenderPhasePlugin` as appropriate instead of directly adding
`batch_and_prepare_render_phase`.

Consolidate Render(Ui)Materials(2d) into RenderAssets (#12827)
# Objective

- Replace `RenderMaterials` / `RenderMaterials2d` / `RenderUiMaterials`
with `RenderAssets` to enable implementing changes to one thing,
`RenderAssets`, that applies to all use cases rather than duplicating
changes everywhere for multiple things that should be one thing.
- Adopts #8149 

## Solution

- Make RenderAsset generic over the destination type rather than the
source type as in #8149
- Use `RenderAssets<PreparedMaterial<M>>` etc for render materials

---

## Changelog

- Changed:
- The `RenderAsset` trait is now implemented on the destination type.
Its `SourceAsset` associated type refers to the type of the source
asset.
- `RenderMaterials`, `RenderMaterials2d`, and `RenderUiMaterials` have
been replaced by `RenderAssets<PreparedMaterial<M>>` and similar.

## Migration Guide

- `RenderAsset` is now implemented for the destination type rather that
the source asset type. The source asset type is now the `RenderAsset`
trait's `SourceAsset` associated type.

Clean up some low level dependencies (#12858)
# Objective
Minimize the number of dependencies low in the tree.

## Solution

* Remove the dependency on rustc-hash in bevy_ecs (not used) and
bevy_macro_utils (only used in one spot).
* Deduplicate the dependency on `sha1_smol` with the existing blake3
dependency already being used for bevy_asset.
 * Remove the unused `ron` dependency on `bevy_app`
* Make the `serde` dependency for `bevy_ecs` optional. It's only used
for serializing Entity.
* Change the `wgpu` dependency to `wgpu-types`, and make it optional for
`bevy_color`.
 * Remove the unused `thread-local` dependency on `bevy_render`.
* Make multiple dependencies for `bevy_tasks` optional and enabled only
when running with the `multi-threaded` feature. Preferably they'd be
disabled all the time on wasm, but I couldn't find a clean way to do
this.

more robust gpu image use (#12606)
# Objective

make morph targets and tonemapping more tolerant of delayed image
loading.

neither of these actually fail currently unless using a bespoke loader
(and even then it would be rare), but i am working on adding throttling
for asset gpu uploads (as a stopgap until we can do proper asset
streaming) and they break with that.

## Solution

when a mesh with morph targets is uploaded to the gpu, the prepare
function uploads the morph target texture if it's available, otherwise
it uploads without morph targets. this is generally fine as long as
morph targets are typically loaded from bytes (in gltf loader), but may
fail for a custom loader if the asset server async-loads the target
texture and the texture is not available yet. the mesh fails to render
and doesn't update when the image is loaded
-> if morph targets are specified but not ready yet, retry mesh upload
next frame

tonemapping `unwrap`s on the lookup table image. this is never a problem
since the image is added via `include_bytes!`, but could be a problem in
future with asset gpu throttling/streaming.
-> if the lookup texture is not yet available, use a fallback
-> in the node, check if the fallback was used before caching the bind

Relax BufferVec's type constraints (#12866)
# Objective
Since BufferVec was first introduced, `bytemuck` has added additional
traits with fewer restrictions than `Pod`. Within BufferVec, we only
rely on the constraints of `bytemuck::cast_slice` to a `u8` slice, which
now only requires `T: NoUninit` which is a strict superset of `Pod`
types.

## Solution
Change out the `Pod` generic type constraint with `NoUninit`. Also
taking the opportunity to substitute `cast_slice` with
`must_cast_slice`, which avoids a runtime panic in place of a compile
time failure if `T` cannot be used.

---

## Changelog
Changed: `BufferVec` now supports working with types containing
`NoUninit` but not `Pod` members.
Changed: `BufferVec` will now fail to compile if used with a type that
cannot be safely read from. Most notably, this includes ZSTs, which
would previously always panic at runtime.

Micro-optimize queue_material_meshes, primarily to remove bit manipulation. (#12791)
This commit makes the following optimizations:

## `MeshPipelineKey`/`BaseMeshPipelineKey` split

`MeshPipelineKey` has been split into `BaseMeshPipelineKey`, which lives
in `bevy_render` and `MeshPipelineKey`, which lives in `bevy_pbr`.
Conceptually, `BaseMeshPipelineKey` is a superclass of
`MeshPipelineKey`. For `BaseMeshPipelineKey`, the bits start at the
highest (most significant) bit and grow downward toward the lowest bit;
for `MeshPipelineKey`, the bits start at the lowest bit and grow upward
toward the highest bit. This prevents them from colliding.

The goal of this is to avoid having to reassemble bits of the pipeline
key for every mesh every frame. Instead, we can just use a bitwise or
operation to combine the pieces that make up a `MeshPipelineKey`.

## `specialize_slow`

Previously, all of `specialize()` was marked as `#[inline]`. This
bloated `queue_material_meshes` unnecessarily, as a large chunk of it
ended up being a slow path that was rarely hit. This commit refactors
the function to move the slow path to `specialize_slow()`.

Together, these two changes shave about 5% off `queue_material_meshes`:

## Migration Guide

- The `primitive_topology` field on `GpuMesh` is now an accessor method:
`GpuMesh::primitive_topology()`.
- For performance reasons, `MeshPipelineKey` has been split into
`BaseMeshPipelineKey`, which lives in `bevy_render`, and
`MeshPipelineKey`, which lives in `bevy_pbr`. These two should be
combined with bitwise-or to produce the final `MeshPipelineKey`.

Refactor App and SubApp internals for better separation (#9202)
# Objective

This is a necessary precursor to #9122 (this was split from that PR to
reduce the amount of code to review all at once).

Moving `!Send` resource ownership to `App` will make it unambiguously
`!Send`. `SubApp` must be `Send`, so it can't wrap `App`.

## Solution

Refactor `App` and `SubApp` to not have a recursive relationship. Since
`SubApp` no longer wraps `App`, once `!Send` resources are moved out of
`World` and into `App`, `SubApp` will become unambiguously `Send`.

There could be less code duplication between `App` and `SubApp`, but
that would break `App` method chaining.

## Changelog

- `SubApp` no longer wraps `App`.
- `App` fields are no longer publicly accessible.
- `App` can no longer be converted into a `SubApp`.
- Various methods now return references to a `SubApp` instead of an
`App`.
## Migration Guide

- To construct a sub-app, use `SubApp::new()`. `App` can no longer
convert into `SubApp`.
- If you implemented a trait for `App`, you may want to implement it for
`SubApp` as well.
- If you're accessing `app.world` directly, you now have to use
`app.world()` and `app.world_mut()`.
- `App::sub_app` now returns `&SubApp`.
- `App::sub_app_mut`  now returns `&mut SubApp`.
- `App::get_sub_app` now returns `Option<&SubApp>.`
- `App::get_sub_app_mut` now returns `Option<&mut SubApp>.`

Improve performance by binning together opaque items instead of sorting them. (#12453)
Today, we sort all entities added to all phases, even the phases that
don't strictly need sorting, such as the opaque and shadow phases. This
results in a performance loss because our `PhaseItem`s are rather large
in memory, so sorting is slow. Additionally, determining the boundaries
of batches is an O(n) process.

This commit makes Bevy instead applicable place phase items into *bins*
keyed by *bin keys*, which have the invariant that everything in the
same bin is potentially batchable. This makes determining batch
boundaries O(1), because everything in the same bin can be batched.
Instead of sorting each entity, we now sort only the bin keys. This
drops the sorting time to near-zero on workloads with few bins like
`many_cubes --no-frustum-culling`. Memory usage is improved too, with
batch boundaries and dynamic indices now implicit instead of explicit.
The improved memory usage results in a significant win even on
unbatchable workloads like `many_cubes --no-frustum-culling
--vary-material-data-per-instance`, presumably due to cache effects.

Not all phases can be binned; some, such as transparent and transmissive
phases, must still be sorted. To handle this, this commit splits
`PhaseItem` into `BinnedPhaseItem` and `SortedPhaseItem`. Most of the
logic that today deals with `PhaseItem`s has been moved to
`SortedPhaseItem`. `BinnedPhaseItem` has the new logic.

Frame time results (in ms/frame) are as follows:

| Benchmark                | `binning` | `main`  | Speedup |
| ------------------------ | --------- | ------- | ------- |
| `many_cubes -nfc -vpi` | 232.179     | 312.123   | 34.43%  |
| `many_cubes -nfc`        | 25.874 | 30.117 | 16.40%  |
| `many_foxes`             | 3.276 | 3.515 | 7.30%   |

(`-nfc` is short for `--no-frustum-culling`; `-vpi` is short for
`--vary-per-instance`.)

---

## Changelog

### Changed

* Render phases have been split into binned and sorted phases. Binned
phases, such as the common opaque phase, achieve improved CPU
performance by avoiding the sorting step.

## Migration Guide

- `PhaseItem` has been split into `BinnedPhaseItem` and
`SortedPhaseItem`. If your code has custom `PhaseItem`s, you will need
to migrate them to one of these two types. `SortedPhaseItem` requires
the fewest code changes, but you may want to pick `BinnedPhaseItem` if
your phase doesn't require sorting, as that enables higher performance.

## Tracy graphs

performance, but it's not nearly enough to outweigh the large gains in
`batch_and_prepare_binned_render_phase`.

Pack the StandardMaterialKey into a single scalar instead of a structure. (#12783)
This commit changes the `StandardMaterialKey` to be based on a set of
bitflags instead of a structure. We hash it every frame for every mesh,
and `#[derive(Hash)]` doesn't generate particularly efficient code for
large structures full of small types. Packing it into a single `u64`
therefore results in a roughly 10% speedup in `queue_material_meshes` on
`many_cubes --no-frustum-culling`.

Make PersistentGpuBufferable a safe trait (#12744)
# Objective
Fixes #12727. All parts that `PersistentGpuBuffer` interact with should
be 100% safe both on the CPU and the GPU: `Queue::write_buffer_with`
zeroes out the slice being written to and when uploading to the GPU, and
all slice writes are bounds checked on the CPU side.

## Solution
Make `PersistentGpuBufferable` a safe trait. Enforce it's correct
implementation via assertions. Re-enable `forbid(unsafe_code)` on
`bevy_pbr`.

Move FloatOrd into bevy_math (#12732)
# Objective

- Fixes #12712

## Solution

- Move the `float_ord.rs` file to `bevy_math`
- Change any `bevy_utils::FloatOrd` statements to `bevy_math::FloatOrd`

---

## Changelog

- Moved `FloatOrd` from `bevy_utils` to `bevy_math`

## Migration Guide

- References to `bevy_utils::FloatOrd` should be changed to
`bevy_math::FloatOrd`

Forbid unsafe in most crates in the engine (#12684)
# Objective
Resolves #3824. `unsafe` code should be the exception, not the norm in
Rust. It's obviously needed for various use cases as it's interfacing
with platforms and essentially running the borrow checker at runtime in
the ECS, but the touted benefits of Bevy is that we are able to heavily
leverage Rust's safety, and we should be holding ourselves accountable
to that by minimizing our unsafe footprint.

## Solution
Deny `unsafe_code` workspace wide. Add explicit exceptions for the
following crates, and forbid it in almost all of the others.

* bevy_ecs - Obvious given how much unsafe is needed to achieve
performant results
* bevy_ptr - Works with raw pointers, even more low level than bevy_ecs.
 * bevy_render - due to needing to integrate with wgpu
 * bevy_window - due to needing to integrate with raw_window_handle
* bevy_utils - Several unsafe utilities used by bevy_ecs. Ideally moved
into bevy_ecs instead of made publicly usable.
 * bevy_reflect - Required for the unsafe type casting it's doing.
 * bevy_transform - for the parallel transform propagation
 * bevy_gizmos  - For the SystemParam impls it has.
* bevy_assets - To support reflection. Might not be required, not 100%
sure yet.
* bevy_mikktspace - due to being a conversion from a C library. Pending
safe rewrite.
* bevy_dynamic_plugin - Inherently unsafe due to the dynamic loading
nature.

Several uses of unsafe were rewritten, as they did not need to be using
them:

* bevy_text - a case of `Option::unchecked` could be rewritten as a
normal for loop and match instead of an iterator.
* bevy_color - the Pod/Zeroable implementations were replaceable with
bytemuck's derive macros.

Meshlet rendering (initial feature) (#10164)
# Objective
- Implements a more efficient, GPU-driven
(https://github.com/bevyengine/bevy/issues/1342) rendering pipeline
based on meshlets.
- Meshes are split into small clusters of triangles called meshlets,
each of which acts as a mini index buffer into the larger mesh data.
Meshlets can be compressed, streamed, culled, and batched much more
efficiently than monolithic meshes.

Set the logo and favicon for all of Bevy's published crates (#12696)
# Objective
Currently the built docs only shows the logo and favicon for the top
level `bevy` crate. This makes views like
https://docs.rs/bevy_ecs/latest/bevy_ecs/ look potentially unrelated to
the project at first glance.

## Solution
Reproduce the docs attributes for every crate that Bevy publishes.

Ideally this would be done with some workspace level Cargo.toml control,
but AFAICT, such support does not exist.

Make feature(doc_auto_cfg) work (#12642)
# Objective

- In #12366 `![cfg_attr(docsrs, feature(doc_auto_cfg))] `was added. But
to apply it it needs `--cfg=docsrs` in rustdoc-args.


## Solution

- Apply `--cfg=docsrs` to all crates and CI.

I also added `[package.metadata.docs.rs]` to all crates to avoid adding
code behind a feature and forget adding the metadata.

Fixes #12600 

## Solution

Removed Into<AssetId<T>> for Handle<T> as proposed in Issue
conversation, fixed dependent code

## Migration guide

If you use passing Handle by value as AssetId, you should pass reference
or call .id() method on it
Before (0.13):
`assets.insert(handle, value);`
After (0.14):
`assets.insert(&handle, value);`
or
`assets.insert(handle.id(), value);`

Add setting to enable/disable shadows to MaterialPlugin (#12538)
# Objective

- Not all materials need shadow, but a queue_shadows system is always
added to the `Render` schedule and executed

## Solution

- Make a setting for shadows, it defaults to true

## Changelog

- Added `shadows_enabled` setting to `MaterialPlugin`

## Migration Guide

- `MaterialPlugin` now has a `shadows_enabled` setting, if you didn't
spawn the plugin using `::default()` or `..default()`, you'll need to
set it. `shadows_enabled: true` is the same behavior as the previous
version, and also the default value.

Add pipeline statistics (#9135)
# Objective

It's useful to have access to render pipeline statistics, since they
provide more information than FPS alone. For example, the number of
drawn triangles can be used to debug culling and LODs. The number of
fragment shader invocations can provide a more stable alternative metric
than GPU elapsed time.

See also: Render node GPU timing overlay #8067, which doesn't provide
pipeline statistics, but adds a nice overlay.

## Solution

Add `RenderDiagnosticsPlugin`, which enables collecting pipeline
statistics and CPU & GPU timings.

---

## Changelog

- Add `RenderDiagnosticsPlugin`
- Add `RenderContext::diagnostic_recorder` method

Update to fixedbitset 0.5 (#12512)
# Objective
Improve code quality involving fixedbitset.

## Solution
Update to fixedbitset 0.5. Use the new `grow_and_insert` function
instead of `grow` and `insert` functions separately.

This should also speed up most of the set operations involving
fixedbitset. They should be ~2x faster, but testing this against the
stress tests seems to show little to no difference. The multithreaded
executor doesn't seem to be all that much faster in many_cubes and
many_foxes. These use cases are likely dominated by other operations or
the bitsets aren't big enough to make them the bottleneck.

This introduces a duplicate dependency due to petgraph and wgpu, but the
former may take some time to update.

## Changelog
Removed: `Access::grow`

## Migration Guide
`Access::grow` has been removed. It's no longer needed. Remove all
references to it.

Add "all-features = true" to docs.rs metadata for most crates (#12366)
# Objective

Fix missing `TextBundle` (and many others) which are present in the main
crate as default features but optional in the sub-crate. See:

- https://docs.rs/bevy/0.13.0/bevy/ui/node_bundles/index.html
- https://docs.rs/bevy_ui/0.13.0/bevy_ui/node_bundles/index.html

~~There are probably other instances in other crates that I could track
down, but maybe "all-features = true" should be used by default in all
sub-crates? Not sure.~~ (There were many.) I only noticed this because
rust-analyzer's "open docs" features takes me to the sub-crate, not the
main one.

## Solution

Add "all-features = true" to docs.rs metadata for crates that use
features.

Disentangle bevy_utils/bevy_core's reexported dependencies (#12313)
# Objective
Make bevy_utils less of a compilation bottleneck. Tackle #11478.

## Solution
* Move all of the directly reexported dependencies and move them to
where they're actually used.
* Remove the UUID utilities that have gone unused since `TypePath` took
over for `TypeUuid`.
* There was also a extraneous bytemuck dependency on `bevy_core` that
has not been used for a long time (since `encase` became the primary way
to prepare GPU buffers).
* Remove the `all_tuples` macro reexport from bevy_ecs since it's
accessible from `bevy_utils`.

## Changelog
Removed: Many of the reexports from bevy_utils (petgraph, uuid, nonmax,
smallvec, and thiserror).
Removed: bevy_core's reexports of bytemuck.

## Migration Guide
bevy_utils' reexports of petgraph, uuid, nonmax, smallvec, and thiserror
have been removed.

bevy_core' reexports of bytemuck's types has been removed.

update comment on emissive field of StandardMaterial struct to mention large color channel values (#12248)
# Objective

- Describe the objective or issue this PR addresses.

Improve docs around emissive colors --

I couldn't figure out how to increase the emissive strength of
materials, asking on discord @alice-i-cecile told me that color channel
values can go above `1.0` in the case of the `emissive` field. I would
have never figured this out on my own, because [the docs for
emissive](https://docs.rs/bevy/latest/bevy/prelude/struct.StandardMaterial.html#structfield.emissive)
don't mention this possibility, and indeed if you follow the link in the
`emissive` doc [to the `Color`
type](https://docs.rs/bevy/latest/bevy/render/color/enum.Color.html#variants),
you are told that values should be in `[0.0, 1.0]`.


## Solution

- Describe the solution used to achieve the objective above.

Just added a note on the possibility of large color channel values with
example.

Intern mesh vertex buffer layouts so that we don't have to compare them over and over. (#12216)
Although we cached hashes of `MeshVertexBufferLayout`, we were paying
the cost of `PartialEq` on `InnerMeshVertexBufferLayout` for every
entity, every frame. This patch changes that logic to place
`MeshVertexBufferLayout`s in `Arc`s so that they can be compared and
hashed by pointer. This results in a 28% speedup in the
`queue_material_meshes` phase of `many_cubes`, with frustum culling
disabled.

Additionally, this patch contains two minor changes:

1. This commit flattens the specialized mesh pipeline cache to one level
of hash tables instead of two. This saves a hash lookup.

2. The example `many_cubes` has been given a `--no-frustum-culling`
flag, to aid in benchmarking.

See the Tracy profile:

## Migration guide

* Duplicate `MeshVertexBufferLayout`s are now combined into a single
object, `MeshVertexBufferLayoutRef`, which contains an
atomically-reference-counted pointer to the layout. Code that was using
`MeshVertexBufferLayout` may need to be updated to use
`MeshVertexBufferLayoutRef` instead.

Migrate from LegacyColor to bevy_color::Color (#12163)
# Objective

- As part of the migration process we need to a) see the end effect of
the migration on user ergonomics b) check for serious perf regressions
c) actually migrate the code
- To accomplish this, I'm going to attempt to migrate all of the
remaining user-facing usages of `LegacyColor` in one PR, being careful
to keep a clean commit history.
- Fixes #12056.

## Solution

I've chosen to use the polymorphic `Color` type as our standard
user-facing API.

- [x] Migrate `bevy_gizmos`.
- [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs
- [x] Migrate sprites
- [x] Migrate UI
- [x] Migrate `ColorMaterial`
- [x] Migrate `MaterialMesh2D`
- [x] Migrate fog
- [x] Migrate lights
- [x] Migrate StandardMaterial
- [x] Migrate wireframes
- [x] Migrate clear color
- [x] Migrate text
- [x] Migrate gltf loader
- [x] Register color types for reflection
- [x] Remove `LegacyColor`
- [x] Make sure CI passes

Incidental improvements to ease migration:

- added `Color::srgba_u8`, `Color::srgba_from_array` and friends
- added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the
`Alpha` trait
- add and immediately deprecate (lol) `Color::rgb` and friends in favor
of more explicit and consistent `Color::srgb`
- standardized on white and black for most example text colors
- added vector field traits to `LinearRgba`: ~~`Add`, `Sub`,
`AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications
and divisions do not scale alpha. `Add` and `Sub` have been cut from
this PR.
- added `LinearRgba` and `Srgba` `RED/GREEN/BLUE`
- added `LinearRgba_to_f32_array` and `LinearRgba::to_u32`

## Migration Guide

Bevy's color types have changed! Wherever you used a
`bevy::render::Color`, a `bevy::color::Color` is used instead.

These are quite similar! Both are enums storing a color in a specific
color space (or to be more precise, using a specific color model).
However, each of the different color models now has its own type.

TODO...

- `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`,
`Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`,
`Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`.
- `Color::set_a` and `Color::a` is now `Color::set_alpha` and
`Color::alpha`. These are part of the `Alpha` trait in `bevy_color`.
- `Color::is_fully_transparent` is now part of the `Alpha` trait in
`bevy_color`
- `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for
`g`, `b` `h`, `s` and `l` have been removed due to causing silent
relatively expensive conversions. Convert your `Color` into the desired
color space, perform your operations there, and then convert it back
into a polymorphic `Color` enum.
- `Color::hex` is now `Srgba::hex`. Call `.into` or construct a
`Color::Srgba` variant manually to convert it.
- `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`,
`ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now
store a `LinearRgba`, rather than a polymorphic `Color`
- `Color::rgb_linear` and `Color::rgba_linear` are now
`Color::linear_rgb` and `Color::linear_rgba`
- The various CSS color constants are no longer stored directly on
`Color`. Instead, they're defined in the `Srgba` color space, and
accessed via `bevy::color::palettes::css`. Call `.into()` on them to
convert them into a `Color` for quick debugging use, and consider using
the much prettier `tailwind` palette for prototyping.
- The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with
the standard naming.
- Vector field arithmetic operations on `Color` (add, subtract, multiply
and divide by a f32) have been removed. Instead, convert your colors
into `LinearRgba` space, and perform your operations explicitly there.
This is particularly relevant when working with emissive or HDR colors,
whose color channel values are routinely outside of the ordinary 0 to 1
range.
- `Color::as_linear_rgba_f32` has been removed. Call
`LinearRgba::to_f32_array` instead, converting if needed.
- `Color::as_linear_rgba_u32` has been removed. Call
`LinearRgba::to_u32` instead, converting if needed.
- Several other color conversion methods to transform LCH or HSL colors
into float arrays or `Vec` types have been removed. Please reimplement
these externally or open a PR to re-add them if you found them
particularly useful.
- Various methods on `Color` such as `rgb` or `hsl` to convert the color
into a specific color space have been removed. Convert into
`LinearRgba`, then to the color space of your choice.
- Various implicitly-converting color value methods on `Color` such as
`r`, `g`, `b` or `h` have been removed. Please convert it into the color
space of your choice, then check these properties.
- `Color` no longer implements `AsBindGroup`. Store a `LinearRgba`
internally instead to avoid conversion costs.

Fix WebGL not rendering StandardMaterial (#12110)
# Objective

- Fixes #12081

## Solution

Passing the `Affine2` as a neatly packed `mat3x2` breaks WebGL with
`drawElementsInstanced: Buffer for uniform block is smaller than
UNIFORM_BLOCK_DATA_SIZE.`
I fixed this by using a `mat3x3` instead.
Alternative solutions that come to mind:
- Pass in a `mat3x2` on non-webgl targets and a `mat3x3` otherwise. I
guess I could use `#ifdef SIXTEEN_BYTE_ALIGNMENT` for this, but it
doesn't seem quite right? This would be more efficient, but decrease
code quality.
- Do something about `UNIFORM_BLOCK_DATA_SIZE`. I don't know how, so I'd
need some guidance here.

@superdump let me know if you'd like me to implement other variants.
Otherwise, I vote for merging this as a quick fix for `main` and then
improving the packing in subsequent PRs :)

## Additional notes

Ideally we should merge this before @JMS55 rebases #10164 so that they
don't have to rebase everything a second time.

Cleanup: Use Parallel in extract_meshes (#12084)
# Objective
#7348 added `bevy_utils::Parallel` and replaced the usage of the
`ThreadLocal<Cell<Vec<...>>>` in `check_visibility`, but we were also
using it in `extract_meshes`.

## Solution
Refactor the system to use `Parallel` instead.

Prefer UVec2 when working with texture dimensions (#11698)
# Objective

The physical width and height (pixels) of an image is always integers,
but for `GpuImage` bevy currently stores them as `Vec2` (`f32`).
Switching to `UVec2` makes this more consistent with the [underlying
texture data](https://docs.rs/wgpu/latest/wgpu/struct.Extent3d.html).

I'm not sure if this is worth the change in the surface level API. If
not, feel free to close this PR.

## Solution

- Replace uses of `Vec2` with `UVec2` when referring to texture
dimensions.
- Use integer types for the texture atlas dimensions and sections.


[`Sprite::rect`](a81a2d1da3/crates/bevy_sprite/src/sprite.rs (L29))
remains unchanged, so manually specifying a sub-pixel region of an image
is still possible.

---

## Changelog

- `GpuImage` now stores its size as `UVec2` instead of `Vec2`.
- Texture atlases store their size and sections as `UVec2` and `URect`
respectively.
- `UiImageSize` stores its size as `UVec2`.

## Migration Guide

- Change floating point types (`Vec2`, `Rect`) to their respective
unsigned integer versions (`UVec2`, `URect`) when using `GpuImage`,
`TextureAtlasLayout`, `TextureAtlasBuilder`,
`DynamicAtlasTextureBuilder` or `FontAtlas`.

Check cfg during CI and fix feature typos (#12103)
# Objective

- Add the new `-Zcheck-cfg` checks to catch more warnings
- Fixes #12091

## Solution

- Create a new `cfg-check` to the CI that runs `cargo check -Zcheck-cfg
--workspace` using cargo nightly (and fails if there are warnings)
- Fix all warnings generated by the new check

---

## Changelog

- Remove all redundant imports
- Fix cfg wasm32 targets
- Add 3 dead code exceptions (should StandardColor be unused?)
- Convert ios_simulator to a feature (I'm not sure if this is the right
way to do it, but the check complained before)

Rename bevy_render::Color to LegacyColor (#12069)
# Objective

The migration process for `bevy_color` (#12013) will be fairly involved:
there will be hundreds of affected files, and a large number of APIs.

## Solution

To allow us to proceed granularly, we're going to keep both
`bevy_color::Color` (new) and `bevy_render::Color` (old) around until
the migration is complete.

However, simply doing this directly is confusing! They're both called
`Color`, making it very hard to tell when a portion of the code has been
ported.

As discussed in #12056, by renaming the old `Color` type, we can make it
easier to gradually migrate over, one API at a time.

## Migration Guide

THIS MIGRATION GUIDE INTENTIONALLY LEFT BLANK.

This change should not be shipped to end users: delete this section in
the final migration guide!

Make more things pub in the renderer (#12053)
# Objective

- Some properties of public types are private but sometimes it's useful
to be able to set those

## Solution

- Make more stuff pub

---

## Changelog

- `MaterialBindGroupId` internal id is now pub and added a new()
constructor
- `ExtractedPointLight` and `ExtractedDirectionalLight` properties are
now all pub

FIX: iOS Simulator not rendering due to missing CUBE_ARRAY_TEXTURES (#12052)
This PR closes #11978

# Objective

Fix rendering on iOS Simulators.

iOS Simulator doesn't support the capability CUBE_ARRAY_TEXTURES, since
0.13 this started to make iOS Simulator not render anything with the
following message being outputted:

```
2024-02-19T14:59:34.896266Z ERROR bevy_render::render_resource::pipeline_cache: failed to create shader module: Validation Error

Caused by:
    In Device::create_shader_module
    
Shader validation error: 


    Type [40] '' is invalid
    Capability Capabilities(CUBE_ARRAY_TEXTURES) is required
```

## Solution

- Split up NO_ARRAY_TEXTURES_SUPPORT into both NO_ARRAY_TEXTURES_SUPPORT
and NO_CUBE_ARRAY_TEXTURES_SUPPORT and correctly apply
NO_ARRAY_TEXTURES_SUPPORT for iOS Simulator using the cfg flag
introduced in #10178.

---

## Changelog

### Fixed
- Rendering on iOS Simulator due to missing CUBE_ARRAY_TEXTURES support.
