I struggled with some sprite sheet animation which was like drifting from right to left.
This PR documents the current behaviour that the padding which is used on slicing a texture into a texture atlas, is assumed to be only between tiles. In my case I had some padding also on the right side of the texture.
# Objective
Noticed a warning when running tests:
```
> cargo test --workspace
warning: output filename collision.
The example target `change_detection` in package `bevy_ecs v0.5.0 (/bevy/crates/bevy_ecs)` has the same output filename as the example target `change_detection` in package `bevy v0.5.0 (/bevy)`.
Colliding filename is: /bevy/target/debug/examples/change_detection
The targets should have unique names.
Consider changing their names to be unique or compiling them separately.
This may become a hard error in the future; see <https://github.com/rust-lang/cargo/issues/6313>.

## Solution
I renamed example `change_detection` to `component_change_detection`
In #2034, the `Remove` Command did not get the same treatment as the rest of the commands. There's no discussion saying it shouldn't have public fields, so I am assuming it was an oversight. This fixes that oversight.
# Objective
- Continue work of #2398 and friends.
- Make `.system()` optional in run criteria APIs.
## Solution
- Slight change to `RunCriteriaDescriptorCoercion` signature and implementors.
- Implement `IntoRunCriteria` for `IntoSystem` rather than `System`.
- Remove some usages of `.system()` with run criteria in tests of `stage.rs`, to verify the implementation.
# Objective
Fixes a possible deadlock between `AssetServer::get_asset_loader` / `AssetServer::add_loader`
A thread could take the `extension_to_loader_index` read lock,
and then have the `server.loader` write lock taken in add_loader
before it can. Then add_loader can't take the extension_to_loader_index
lock, and the program deadlocks.
To be more precise:
## Step 1: Thread 1 grabs the `extension_to_loader_index` lock on lines 138..139:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L133-L145)
## Step 2: Thread 2 grabs the `server.loader` write lock on line 107:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L103-L116)
## Step 3: Deadlock, since Thread 1 wants to grab `server.loader` on line 141...:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L133-L145)
... and Thread 2 wants to grab 'extension_to_loader_index` on lines 111..112:
3a1867a92e/crates/bevy_asset/src/asset_server.rs (L103-L116)
## Solution
Fixed by descoping the extension_to_loader_index lock, since
`get_asset_loader` doesn't need to hold the read lock on the extensions map for the duration,
just to get a copyable usize. The block might not be needed,
I think I could have gotten away with just inserting a `copied()`
call into the chain, but I wanted to make the reasoning clear for
future maintainers.
# Objective
- Describe the objective or issue this PR addresses.
- added openSUSE Tumbleweed deps that i needed to install today 2021-06-22
## Solution
- Describe the solution used to achieve the objective above.
- added info to doc
# Objective
I wanted to send the Bevy discord link to someone but couldn't find a pretty link to copy paste
## Solution
Use the vanity link we have for discord
# Objective
Fixes how the layer bit is unset in the RenderLayers bit mask when calling the `without` method.
## Solution
Unsets the layer bit using `&=` and the inverse of the layer bit mask.
# Objective
Beginners semi-regularly appear on the Discord asking for help with using `QuerySet` when they have a system with conflicting data access.
This happens because the Resulting Panic message only mentions `QuerySet` as a solution, even if in most cases `Without<T>` was enough to solve the problem.
## Solution
Mention the usage of `Without<T>` to create disjoint queries as an alternative to `QuerySet`
## Open Questions
- Is `disjoint` a too technical/mathematical word?
- Should `Without<T>` be mentioned before or after `QuerySet`?
- Before: Using `Without<T>` should be preferred and mentioning it first reinforces this for a reader.
- After: The Panics can be very long and a Reader could skip to end and only see the `QuerySet`

# Objective
- Continue work of #2398 and #2403.
- Make `.system()` syntax optional when using `.config()` API.
## Solution
- Introduce new prelude trait, `ConfigurableSystem`, that shorthands `my_system.system().config(...)` as `my_system.config(...)`.
- Expand `configure_system_local` test to also cover the new syntax.
# Objective
- Add inline documentation for `StorageType`.
- Currently the README in `bevy_ecs` provides docs for `StorageType`, however, adding addition inline docs makes it simpler for users who are actively reading the source code.
## Solution
- Add inline docs.
# Objective
- Extend work done in #2398.
- Make `.system()` syntax optional when using system descriptor API.
## Solution
- Slight change to `ParallelSystemDescriptorCoercion` signature and implementors.

I haven't touched exclusive systems, because it looks like the only two other solutions are going back to doubling our system insertion methods, or starting to lean into stageless. The latter will invalidate the former, so I think exclusive systems should remian pariahs until stageless.
I can grep & nuke `.system()` thorughout the codebase now, which might take a while, or we can do that in subsequent PR(s).
# Objective
- Currently the `Commands` and `CommandQueue` have no performance testing.
- As `Commands` are quite expensive due to the `Box<dyn Command>` allocated for each command, there should be perf tests for implementations that attempt to improve the performance.
## Solution
- Add some benchmarking for `Commands` and `CommandQueue`.
This can be your 6 months post-christmas present.
# Objective
- Make `.system` optional
- yeet
- It's ugly
- Alternative title: `.system` is dead; long live `.system`
- **yeet**
## Solution
- Use a higher ranked lifetime, and some trait magic.
N.B. This PR does not actually remove any `.system`s, except in a couple of examples. Once this is merged we can do that piecemeal across crates, and decide on syntax for labels.
# Objective
Re-introduce `AHashExt` and respective `with_capacity()` implementations to give a more ergonomic way to set a `HashMap` / `HashSet` capacity.
As a note, this has also been discussed and agreed on issue #2115, which this PR addresses (leaving `new()` out of the `AHashExt` trait).
Fixes#2115.
## Solution
PR #1235 had removed the `AHashExt` trait and respective `with_capacity()`s implementations, leaving only the less ergonomic `HashMap::with_capacity_and_hasher(size, Default::default())` option available.
This re-introduces `AHashExt` and respective `with_capacity()` implementations to give a more ergonomic way to set a `HashMap` / `HashSet` capacity.
# Objective
Currently, you can add `Option<Res<T>` or `Option<ResMut<T>` as a SystemParam, if the Resource could potentially not exist, but this functionality doesn't exist for `NonSend` and `NonSendMut`
## Solution
Adds implementations to use `Option<NonSend<T>>` and Option<NonSendMut<T>> as SystemParams.
Updates the requirements on [wgpu](https://github.com/gfx-rs/wgpu) to permit the latest version.

# Objective
- Make it so that `Time` can be cloned
- Makes it so I can clone the entire current `Time` and easily pass it to the user in [Rusty Engine](https://github.com/CleanCut/rusty_engine) instead of [doing this](8302dc3914/src/game.rs (L147-L150))
## Solution
- Derive the `Clone` trait on `Time`
# Objective
- CI jobs are starting to fail due to `clippy::bool-assert-comparison` and `clippy::single_component_path_imports` being triggered.
## Solution
- Fix all uses where `asset_eq!(<condition>, <bool>)` could be replace by `assert!`
- Move the `#[allow()]` for `single_component_path_imports` to `#![allow()]` at the start of the files.
# Objective
- Currently `AssetServer::get_handle_path` always returns `None` since the inner hash map is never written to.
## Solution
- Inside the `load_untracked` function, insert the asset path into the map.
This is similar to #1290 (thanks @TheRawMeatball)
# Objective
- The `DetectChanges` trait is used for types that detect change on mutable access (such as `ResMut`, `Mut`, etc...)
- `DetectChanges` was not implemented for `NonSendMut`
## Solution
- implement `NonSendMut` in terms of `DetectChanges`
# Objective
Currently, you can't call `is_added` or `is_changed` on a `NonSend` SystemParam, unless the Resource is a Component (implements `Send` and `Sync`).
This defeats the purpose of providing change detection for NonSend Resources.
While fixing this, I also noticed that `NonSend` does not have a bound at all on its struct.
## Solution
Change the bounds of `T` to always be `'static`.
# Objective
- MPL should not be an authorised license for all crates
## Solution
- Add exception for MPL for wgpu and hexasphere
- Remove security issue for a crate we don't depend on anymore
# Objective
Prevent future unnecessary mental effort spent figuring out why this trait exists and how to resolve the `TODO`.
## Solution
I happened to notice this trait being used when expanding the `#[derive(Reflect)]` macro in my own crate to figure out how it worked, and noticed that there was a `TODO` comment on it because it is only used in the derive macro and thus appeared to be unused.
I figured I should document my findings to prevent someone else from finding them out the hard way in the future 😆

# Objective
- Currently, when calling any of the `AssetServer`'s `load` functions, if the extension does not exist for the given path, the returned handle's load state is always `LoadState::NotLoaded`.
- This is due to the `load_async` function early returning without properly creating a `SourceInfo` for the requested asset.
- Fixes#2261
## Solution
- Add the `SourceInfo` prior to checking for valid extension loaders. And set the `LoadState` to `Failed` if the according loader does not exist.
When loading a gltf, if there is an error loading textures, it is completely ignored.
This can happen for example when loading a file with `jpg` textures without the `jpeg` Bevy feature enabled.
This PR adds `warn` logs for the few cases that can happen when loading a texture.
Other possible fix would be to break on first error and returning, making the asset loading failed
1) Sets `LoadState` properly on all failing cases in `AssetServer::load_async`
2) Adds more tests for sad and happy paths of asset loading
_Note_: this brings in the `tempfile` crate.
fixes#2169
Instead of having custom methods with reduced visibility, implement `From<image::DynamicImage> for Texture` and `TryFrom<Texture> for image::DynamicImage`
[RENDERED](https://github.com/NiklasEi/bevy/blob/ecs_readme/crates/bevy_ecs/README.md)
Since I am trying to learn more about Bevy ECS at the moment, I thought this issue is a perfect fit.
This PR adds a readme to the `bevy_ecs` crate containing a minimal running example of stand alone `bevy_ecs`. Unique features like customizable component storage, Resources or change detection are introduced. For each of these features the readme links to an example in a newly created examples directory inside the `bevy_esc` crate.
Resolves#2008

# Objective
- the PR labeler workflow will always add the `needs-traige` label to every pull request event
## Solution
- Limit this workflow to only be on the `opened` event
# Objective
- Currently only issues automatically have labels assigned to them on creation.
- The enables pull requests to have the same functionality and currently only adds the `needs-triage` label to all PRs.
## Solution
- Integrate `actions/labeler@v2` into the github workflows to automatically tag PRs.
- Add a `label-config.yml` file that specifies how PRs should be labeled.
Since `visible_entities_system` already checks `Visiblie::is_visible` for each entity and requires it to be `true`, there's no reason to verify visibility in `PassNode::prepare` which consumes entities produced by the system.
# Objective
- When creating an asset, the `update_asset_storage` function was unnecessarily creating an extraneous `Handle` to the created asset via calling `set`. This has some overhead as the `RefChange::Increment/Decrement` event was being sent.
- A similar exteraneous handle is also created in `load_async` when loading dependencies.
## Solution
- Have the implementation use `Assets::set_untracked` and `AssetServer::load_untracked` so no intermediate handle is created.
When implementing `AssetLoader ` you need to specify which File extensions are supported by that loader.
Currently, Bevy always says it supports extensions that actually require activating a Feature beforehand.
This PR adds cf attributes, so Bevy only tries to load those Extensions whose Features were activated.
This prevents Bevy from Panicking and reports such a warning:
```
Jun 02 23:05:57.139 WARN bevy_asset::asset_server: no `AssetLoader` found for the following extension: ogg
```
This also fixes the Bug, that the `png Feature had to be activated even if you wanted to load a different image format.
Fixes#640
## Problem
- The `Query` struct does not provide an easy way to check if it is empty.
- Specifically, users have to use `.iter().peekable()` or `.iter().next().is_none()` which is not very ergonomic.
- Fixes: #2270
## Solution
- Implement an `is_empty` function for queries to more easily check if the query is empty.
