- [x] Switch from a bash script to an xtask rust workspace member.
- Results in ~30s longer CI due to compilation of the xtask itself
- Enables Bevy contributors on any platform to run `cargo ci` to run linting -- if the default available Rust is the same version as on CI, then the command should give an identical result.
- [x] Use the xtask from official CI so there's only one place to update.
- [x] Bonus: Run clippy on the _entire_ workspace (existing CI setup was missing the `--workspace` flag
- [x] Clean up newly-exposed clippy errors
~#1388 builds on this to clean up newly discovered clippy errors -- I thought it might be nicer as a separate PR.~ Nope, merged it into this one so CI would pass.

The provided Rules are documented here: https://github.com/DavidAnson/markdownlint/blob/v0.23.1/doc/Rules.md
Rules I didn't follow/fix:

The `bevy_winit` crate hasn't been able to build on docs.rs [since 0.2.1](https://docs.rs/crate/bevy_winit/0.4.0). This PR restores the ability of docs.rs to build `bevy_winit` again.
(The choice of backend is essentially arbitrary, but choosing one *is required* for the crate to build)
For some cases, like driving a full screen fragment shader, it is sometimes convenient to not have to create and upload a mesh because the necessary vertices are simple to synthesize in the vertex shader. Bevy's existing pipeline compiler assumes that there will always be a vertex buffer. This PR changes that such that vertex buffer descriptor is only added to the pipeline layout if there are vertex attributes in the shader.
Before, when deriving `SystemLabel` for a type without `Clone`, the error message was:
```
the trait `SystemLabel` is not implemented for `&TransformSystem`
```
Now it is
```
the trait `Clone` is not implemented for `TransformSystem`
```
which directly shows what's needed to fix the problem.
* Simple Implementation to address #1327 by adding a focused field to the window and related system
* Changing Window update function from bevy_window to bevy_winit.
* Removing unused imports.
the mailbox option doesn't do framelimiting on some devices. we need to rely on vsync for framelimiting until bevy supports framelimiting internally. #1343
The existing snippet fails to compile with:
```
no method named `system` found for fn item `fn(bevy::prelude::Commands) {example_system}` in the current scope
```
The `Texture::convert` function previously was only compiled when
one of the image format features (`png`, `jpeg` etc.) were enabled.
The `bevy_sprite` crate needs this function though, which led
to compilation errors when using `cargo check --no-default-features
--features render`.
Now the `convert` function has no features and the `texture_to_image`
and `image_to_texture` utilites functions are in an unconditionally
compiled module.
* Fix Interaction getting stuck when pressing and releasing mouse button in one frame
* Fix Interaction not resetting in some cases with FocusPolicy::Pass
* use `length_squared` for visible entities
* ortho projection 2d/3d different depth calculation
* use ScalingMode::FixedVertical for 3d ortho
* new example: 3d orthographic
* add normalized orthographic projection
* custom scale for ScaledOrthographicProjection
* allow choosing base axis for ScaledOrthographicProjection
* cargo fmt
* add general (scaled) orthographic camera bundle
FIXME: does the same "far" trick from Camera2DBundle make any sense here?
* fixes
* camera bundles: rename and new ortho constructors
* unify orthographic projections
* give PerspectiveCameraBundle constructors like those of OrthographicCameraBundle
* update examples with new camera bundle syntax
* rename CameraUiBundle to UiCameraBundle
* update examples
* ScalingMode::None
* remove extra blank lines
* sane default bounds for orthographic projection
* fix alien_cake_addict example
* reorder ScalingMode enum variants
* ios example fix
* Remove AHashExt
There is little benefit of Hash*::new() over Hash*::default(), but it
does require more code that needs to be duplicated for every Hash* in
bevy_utils. It may also slightly increase compile times.
* Add StableHash* to bevy_utils
* Use StableHashMap instead of HashMap + BTreeSet for diagnostics
This is a significant reduction in the release mode compile times of
bevy_diagnostics

Relying on TypeId being some hash internally isn't future-proof because there is no guarantee about internal layout or structure of TypeId. I benchmarked TypeId noop hasher vs fxhash and found that there is very little difference.
Also fxhash is likely to be better supported because it is widely used in rustc itself.

Previously, if the actual value of LeftStickX was e.g. 0.034 and fluctuated a little
bit (less than the threshold) it would repeatedly send out events,
because it compared the value to the *filtered* old one - 0.0 - which is
more then `0.01` (the threshold) away.
The is fixed by first doing the deadzone and then comparing to the old
value.
Another possible solution would be to store both the actual old value
and the filtered one, but that would add complexity.
improve quality of text2d rendering
* remove coordinate tweaking in sprite-sheet shader
* fixes glyph shimmering of animated text
* reposition glyph before passing it to ab_glyph to normalize its rendering
The result of layout of sequence of glyphs causes individuals to have fractional positions, but since glyph renderings are reused for future instances of that glyph, this produces errors. This change accepts the errors but repositions the glyph to "0, 0" in an effort to get the cleanest possible rendering.
make more information available from loaded GLTF model
* make gltf nodes available as assets
* add list of primitive per mesh, and their associated material
* complete gltf structure
* get names of gltf assets
* only load materials once
* add labels with node names
* Test entity labels, fixed corner cases, changed interface
* add tests for entity_labels_system
* fixed filling label_entities map
* fixed corner cases when removing entities, Labels component
* changed EntityLabels::get to return slice or empty slice instead of
None or Some empty or non-empty slice
Changing the interface of EntityLabels::get is beneficial, since else
you would get different results in case there was an entity before that
with this missing label or not. You would either get None or Some(&[])
and need to handle both, which is actually not necessary.
* register type Labels in CorePlugin
* move print diagnostics to log
* entity count diagnostic
* asset count diagnostic
* remove useless `pub`s
* use `BTreeMap` instead of `HashMap`
* get entity count from world
* keep ordered list of diagnostics
* ignore error when setting global tracing subscriber
* ignore unfocus event on window closed previously
* update example to show how to disable LogPlugin
* Update tracing-chrome to 0.3.0
* bevy_log: Add fields to span names for tracing-chrome
* Conditionally import tracing_subscriber modules based on feature
* only update global transforms when they (or their ancestors) have changed
* only update render resource nodes when they have changed (quality check plz)
* only update entity mesh specialization when mesh (or mesh component) has changed
* only update sprite size when changed
* remove stale bind groups
* fix setting size of loading sprites
* store unmatched render resource binding results
* reduce state changes
* cargo fmt + clippy
* remove cached "NoMatch" results when new bindings are added to RenderResourceBindings
* inline current_entity in world_builder
* try creating bind groups even when they havent changed
* render_resources_node: update all entities when resized
* fmt
* Rename reflect 'hash' method to 'reflect_hash' to avoid colliding with std:#️⃣:Hash::hash to resolve#943.
* Rename partial_eq to reflect_partial_eq to avoid collisions with implementations of PartialEq on primitives.
While generally speaking the calling thread would have picked up the task first anyways, I don't think it makes much sense usually to block the calling thread until another thread wakes and does the work.
* Rename test components for easier understanding of failures
* Make recursive despawn public
This way, threadlocal systems can despawn hierarchies.
* Swap children before despawning
* Add test for ui-z system
* Remove generic hierarchy runner and refactor ui z-system
* Remove different handling for childless nodes
Having an empty children list should be the same as having no child
component.
* Further simplify system after change
