Apply Clippy lints regarding lazy evaluation and closures (#14015)
# Objective

- Lazily evaluate
[default](https://rust-lang.github.io/rust-clippy/master/index.html#/unwrap_or_default)~~/[or](https://rust-lang.github.io/rust-clippy/master/index.html#/or_fun_call)~~
values where it makes sense
  - ~~`unwrap_or(foo())` -> `unwrap_or_else(|| foo())`~~
  - `unwrap_or(Default::default())` -> `unwrap_or_default()`
  - etc.
- Avoid creating [redundant
closures](https://rust-lang.github.io/rust-clippy/master/index.html#/redundant_closure),
even for [method
calls](https://rust-lang.github.io/rust-clippy/master/index.html#/redundant_closure_for_method_calls)
  - `map(|something| something.into())` -> `map(Into:into)`

## Solution

- Apply Clippy lints:
-
~~[or_fun_call](https://rust-lang.github.io/rust-clippy/master/index.html#/or_fun_call)~~
-
[unwrap_or_default](https://rust-lang.github.io/rust-clippy/master/index.html#/unwrap_or_default)
-
[redundant_closure_for_method_calls](https://rust-lang.github.io/rust-clippy/master/index.html#/redundant_closure_for_method_calls)
([redundant
closures](https://rust-lang.github.io/rust-clippy/master/index.html#/redundant_closure)
is already enabled)

## Testing

- Tested on Windows 11 (`stable-x86_64-pc-windows-gnu`, 1.79.0)
- Bevy compiles without errors or warnings and examples seem to work as
intended
  - `cargo clippy` 
  - `cargo run -p ci -- compile`

Updates default Text font size to 24px (#13603)
# Objective

- The default font size is too small to be useful in examples or for
debug text.
- Fixes #13587

## Solution

- Updated the default font size value in `TextStyle` from 12px to 24px.
- Resorted to Text defaults in examples to use the default font size in
most of them.

## Testing

- WIP

---

## Migration Guide

- The default font size has been increased to 24px from 12px. Make sure
you set the font to the appropriate values in places you were using
`Default` text style.

Use standard instruction text / position in various examples (#13583)
## Objective

Use the "standard" text size / placement for the new text in these
examples.

Continuation of an effort started here:
https://github.com/bevyengine/bevy/pull/8478

This is definitely not comprehensive. I did the ones that were easy to
find and relatively straightforward updates. I meant to just do
`3d_shapes` and `2d_shapes`, but one thing lead to another.

## Solution

Use `font_size: 20.0`, the default (built-in) font, `Color::WHITE`
(default), and `Val::Px(12.)` from the edges of the screen.

There are a few little drive-by cleanups of defaults not being used,
etc.

## Testing

Ran the changed examples, verified that they still look reasonable.

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.

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!

Inverse missing_docs logic (#11676)
# Objective

Currently the `missing_docs` lint is allowed-by-default and enabled at
crate level when their documentations is complete (see #3492).
This PR proposes to inverse this logic by making `missing_docs`
warn-by-default and mark crates with imcomplete docs allowed.

## Solution

Makes `missing_docs` warn at workspace level and allowed at crate level
when the docs is imcomplete.

Use the Continuous update mode in stress tests when unfocused (#11652)
# Objective

- When running any of the stress tests, the refresh rate is currently
capped to 60hz because of the `ReactiveLowPower` default used when the
window is not in focus. Since stress tests should run as fast as
possible (and as such vsync is disabled for all of them), it makes sense
to always run them in `Continuous` mode. This is especially useful to
avoid capturing non-representative frame times when recording a Tracy
frame.

## Solution

- Always use the `Continuous` update mode in stress tests.

Replace DiagnosticId by DiagnosticPath (#9266)
# Objective

Implements #9216 

## Solution

- Replace `DiagnosticId` by `DiagnosticPath`. It's pre-hashed using
`const-fnv1a-hash` crate, so it's possible to create path in const
contexts.

---

## Changelog

- Replaced `DiagnosticId` by `DiagnosticPath`
- Set default history length to 120 measurements (2 seconds on 60 fps).

I've noticed hardcoded constant 20 everywhere and decided to change it
to `DEFAULT_MAX_HISTORY_LENGTH` , which is set to new diagnostics by
default. To override it, use `with_max_history_length`.


## Migration Guide

```diff
- const UNIQUE_DIAG_ID: DiagnosticId = DiagnosticId::from_u128(42);
+ const UNIQUE_DIAG_PATH: DiagnosticPath = DiagnosticPath::const_new("foo/bar");

- Diagnostic::new(UNIQUE_DIAG_ID, "example", 10)
+ Diagnostic::new(UNIQUE_DIAG_PATH).with_max_history_length(10)

- diagnostics.add_measurement(UNIQUE_DIAG_ID, || 42);
+ diagnostics.add_measurement(&UNIQUE_DIAG_ID, || 42);

Update winit dependency to 0.29 (#10702)
# Objective

- Update winit dependency to 0.29

## Changelog

### KeyCode changes

- Removed `ScanCode`, as it was [replaced by
KeyCode](https://github.com/rust-windowing/winit/blob/master/CHANGELOG.md#0292).
- `ReceivedCharacter.char` is now a `SmolStr`, [relevant
doc](https://docs.rs/winit/latest/winit/event/struct.KeyEvent.html#structfield.text).
- Changed most `KeyCode` values, and added more.

KeyCode has changed meaning. With this PR, it refers to physical
position on keyboard rather than the printed letter on keyboard keys.

In practice this means:
- On QWERTY keyboard layouts, nothing changes
- On any other keyboard layout, `KeyCode` no longer reflects the label
on key.
- This is "good". In bevy 0.12, when you used WASD for movement, users
with non-QWERTY keyboards couldn't play your game! This was especially
bad for non-latin keyboards. Now, WASD represents the physical keys. A
French player will press the ZQSD keys, which are near each other,
Kyrgyz players will use "Цфыв".
- This is "bad" as well. You can't know in advance what the label of the
key for input is. Your UI says "press WASD to move", even if in reality,
they should be pressing "ZQSD" or "Цфыв". You also no longer can use
`KeyCode` for text inputs. In any case, it was a pretty bad API for text
input. You should use `ReceivedCharacter` now instead.

### Other changes
- Use `web-time` rather than `instant` crate.
(https://github.com/rust-windowing/winit/pull/2836)
- winit did split `run_return` in `run_onDemand` and `pump_events`, I
did the same change in bevy_winit and used `pump_events`.
- Removed `return_from_run` from `WinitSettings` as `winit::run` now
returns on supported platforms.
- I left the example "return_after_run" as I think it's still useful.
- This winit change is done partly to allow to create a new window after
quitting all windows: https://github.com/emilk/egui/issues/1918 ; this
PR doesn't address.
- added `width` and `height` properties in the `canvas` from wasm
example
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1420567168)

## Known regressions (important follow ups?)
- Provide an API for reacting when a specific key from current layout
was released.
- possible solutions: use winit::Key from winit::KeyEvent ; mapping
between KeyCode and Key ; or .
- We don't receive characters through alt+numpad (e.g. alt + 151 = "ù")
anymore ; reproduced on winit example "ime". maybe related to
https://github.com/rust-windowing/winit/issues/2945
- (windows) Window content doesn't refresh at all when resizing. By
reading https://github.com/rust-windowing/winit/issues/2900 ; I suspect
we should just fire a `window.request_redraw();` from `AboutToWait`, and
handle actual redrawing within `RedrawRequested`. I'm not sure how to
move all that code so I'd appreciate it to be a follow up.
- (windows) unreleased winit fix for using set_control_flow in
AboutToWait https://github.com/rust-windowing/winit/issues/3215 ; ⚠️ I'm
not sure what the implications are, but that feels bad 🤔

## Follow up 

I'd like to avoid bloating this PR, here are a few follow up tasks
worthy of a separate PR, or new issue to track them once this PR is
closed, as they would either complicate reviews, or at risk of being
controversial:
- remove CanvasParentResizePlugin
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1417068856)
- avoid mentionning explicitly winit in docs from bevy_window ?
- NamedKey integration on bevy_input:
https://github.com/rust-windowing/winit/pull/3143 introduced a new
NamedKey variant. I implemented it only on the converters but we'd
benefit making the same changes to bevy_input.
- Add more info in KeyboardInput
https://github.com/bevyengine/bevy/pull/10702#pullrequestreview-1748336313
- https://github.com/bevyengine/bevy/pull/9905 added a workaround on a
bug allegedly fixed by winit 0.29. We should check if it's still
necessary.
- update to raw_window_handle 0.6
  - blocked by wgpu
- Rename `KeyCode` to `PhysicalKeyCode`
https://github.com/bevyengine/bevy/pull/10702#discussion_r1404595015
- remove `instant` dependency, [replaced
by](https://github.com/rust-windowing/winit/pull/2836) `web_time`), we'd
need to update to :
  - fastrand >= 2.0
- [`async-executor`](https://github.com/smol-rs/async-executor) >= 1.7
    - [`futures-lite`](https://github.com/smol-rs/futures-lite) >= 2.0
- Verify license, see
[discussion](https://github.com/bevyengine/bevy/pull/8745#discussion_r1402439800)
  - we might be missing a short notice or description of changes made
- Consider using https://github.com/rust-windowing/cursor-icon directly
rather than vendoring it in bevy.
- investigate [this
unwrap](https://github.com/bevyengine/bevy/pull/8745#discussion_r1387044986)
(`winit_window.canvas().unwrap();`)
- Use more good things about winit's update
- https://github.com/bevyengine/bevy/pull/10689#issuecomment-1823560428

Use a consistent scale factor and resolution in stress tests (#10474)
# Objective

Related to #10472.

Not having a hardcoded scale factor makes comparing results from these
stress tests difficult.

Contributors using high dpi screens may be rendering 4x as many pixels
as others (or more). Stress tests may have different behavior when moved
from one monitor in a dual setup to another. At very high resolutions,
different parts of the engine / hardware are being stressed.

1080p is also a far more common resolution for gaming.

## Solution

Use a consistent 1080p with `scale_factor_override: 1.0` everywhere.

In #9903, this sort of change was added specifically to `bevymark` and
`many_cubes` but it makes sense to do it everywhere.

## Discussion

- Maybe we should have a command line option, environment variable, or
`CI_TESTING_CONFIG` option for 1080p / 1440p / 4k.

- Will these look odd (small text?) when screenshotted and shown in the
example showcase? The aspect ratio is the same, but they will be
downscaled from 1080p instead of ~720p.

- Maybe there are other window properties that should be consistent
across stress tests. e.g. `resizable: false`.

- Should we add a `stress_test_window(title)` helper or something?

- Bevymark (pre-10472) was intentionally 800x600 to match "bunnymark", I
believe. I don't personally think this is very important.

Fix CI for Rust 1.72 (#9562)
# Objective

[Rust 1.72.0](https://blog.rust-lang.org/2023/08/24/Rust-1.72.0.html) is
now stable.

# Notes

- `let-else` formatting has arrived!
- I chose to allow `explicit_iter_loop` due to
https://github.com/rust-lang/rust-clippy/issues/11074.
  
We didn't hit any of the false positives that prevent compilation, but
fixing this did produce a lot of the "symbol soup" mentioned, e.g. `for
image in &mut *image_events {`.
  
  Happy to undo this if there's consensus the other way.

Allow tuples and single plugins in add_plugins, deprecate add_plugin (#8097)
# Objective

- Better consistency with `add_systems`.
- Deprecating `add_plugin` in favor of a more powerful `add_plugins`.
- Allow passing `Plugin` to `add_plugins`.
- Allow passing tuples to `add_plugins`.

## Solution

- `App::add_plugins` now takes an `impl Plugins` parameter.
- `App::add_plugin` is deprecated.
- `Plugins` is a new sealed trait that is only implemented for `Plugin`,
`PluginGroup` and tuples over `Plugins`.
- All examples, benchmarks and tests are changed to use `add_plugins`,
using tuples where appropriate.

---

## Changelog

### Changed

- `App::add_plugins` now accepts all types that implement `Plugins`,
which is implemented for:
  - Types that implement `Plugin`.
  - Types that implement `PluginGroup`.
  - Tuples (up to 16 elements) over types that implement `Plugins`.
- Deprecated `App::add_plugin` in favor of `App::add_plugins`.

## Migration Guide

- Replace `app.add_plugin(plugin)` calls with `app.add_plugins(plugin)`.

Instanced line rendering for gizmos based on bevy_polyline (#8427)
# Objective

Adopt code from
[bevy_polyline](https://github.com/ForesightMiningSoftwareCorporation/bevy_polyline)
for gizmo line-rendering.
This adds configurable width and perspective rendering for the lines.

Many thanks to @mtsr for the initial work on bevy_polyline. Thanks to
@aevyrie for maintaining it, @nicopap for adding the depth_bias feature
and the other
[contributors](https://github.com/ForesightMiningSoftwareCorporation/bevy_polyline/graphs/contributors)
for squashing bugs and keeping bevy_polyline up-to-date.

Somewhat unexpectedly, the performance is improved with this PR.
At 200,000 lines in many_gizmos I get ~110 FPS on main and ~200 FPS with
this PR.
I'm guessing this is a CPU side difference as I would expect the
rendering technique to be more expensive on the GPU to some extent, but
I am not entirely sure.

Allow systems using Diagnostics to run in parallel (#8677)
# Objective

I was trying to add some `Diagnostics` to have a better break down of
performance but I noticed that the current implementation uses a
`ResMut` which forces the functions to all run sequentially whereas
before they could run in parallel. This created too great a performance
penalty to be usable.

## Solution

This PR reworks how the diagnostics work with a couple of breaking
changes. The idea is to change how `Diagnostics` works by changing it to
a `SystemParam`. This allows us to hold a `Deferred` buffer of
measurements that can be applied later, avoiding the need for multiple
mutable references to the hashmap. This means we can run systems that
write diagnostic measurements in parallel.

Firstly, we rename the old `Diagnostics` to `DiagnosticsStore`. This
clears up the original name for the new interface while allowing us to
preserve more closely the original API.

Then we create a new `Diagnostics` struct which implements `SystemParam`
and contains a deferred `SystemBuffer`. This can be used very similar to
the old `Diagnostics` for writing new measurements.

```rust
fn system(diagnostics: ResMut<Diagnostics>) { diagnostics.new_measurement(ID, || 10.0)}
// changes to
fn system(mut diagnostics: Diagnostics) { diagnostics.new_measurement(ID, || 10.0)}
``` 
For reading the diagnostics, the user needs to change from `Diagnostics`
to `DiagnosticsStore` but otherwise the function calls are the same.

Finally, we add a new method to the `App` for registering diagnostics.
This replaces the old method of creating a startup system and adding it
manually.

Testing it, this PR does indeed allow Diagnostic systems to be run in
parallel.

## Changelog

- Change `Diagnostics` to implement `SystemParam` which allows
diagnostic systems to run in parallel.

## Migration Guide

- Register `Diagnostic`'s using the new
`app.register_diagnostic(Diagnostic::new(DIAGNOSTIC_ID,
"diagnostic_name", 10));`
- In systems for writing new measurements, change `mut diagnostics:
ResMut<Diagnostics>` to `mut diagnostics: Diagnostics` to allow the
systems to run in parallel.
- In systems for reading measurements, change `diagnostics:
Res<Diagnostics>` to `diagnostics: Res<DiagnosticsStore>`.

- Add a font based on FiraMono containing only ASCII characters and use
it as the default font
- It is behind a feature `default_font` enabled by default
- I also updated examples to use it, but not UI examples to still show
how to use a custom font

---

## Changelog

* If you display text without using the default handle provided by
`TextStyle`, the text will be displayed

Immediate Mode Line/Gizmo Drawing (#6529)
# Objective
Add a convenient immediate mode drawing API for visual debugging.

Fixes #5619
Alternative to #1625
Partial alternative to #5734

Based off https://github.com/Toqozz/bevy_debug_lines with some changes:
 * Simultaneous support for 2D and 3D.
 * Methods for basic shapes; circles, spheres, rectangles, boxes, etc.
 * 2D methods.
 * Removed durations. Seemed niche, and can be handled by users.

<summary>Performance</summary>

Stress tested using Bevy's recommended optimization settings for the dev
profile with the
following command.
```bash
cargo run --example many_debug_lines \
    --config "profile.dev.package.\"*\".opt-level=3" \
    --config "profile.dev.opt-level=1"
```
I dipped to 65-70 FPS at 300,000 lines
CPU: 3700x
RAM Speed: 3200 Mhz
GPU: 2070 super - probably not very relevant, mostly cpu/memory bound

 * Added `Gizmos` system parameter for drawing lines and wireshapes.

### TODO
- [ ] Update changelog
- [x] Update performance numbers
- [x] Add credit to PR description

### Future work
- Cache rendering primitives instead of constructing them out of line
segments each frame.
- Support for drawing solid meshes
- Interactions. (See
[bevy_mod_gizmos](https://github.com/LiamGallagher737/bevy_mod_gizmos))
- Fancier line drawing. (See
[bevy_polyline](https://github.com/ForesightMiningSoftwareCorporation/bevy_polyline))
- Support for `RenderLayers`
- Display gizmos for a certain duration. Currently everything displays
for one frame (ie. immediate mode)
- Changing settings per drawn item like drawing on top or drawing to
different `RenderLayers`
