8eedc8f69d ShaderDefVal: add an UInt option (#6881)
# Objective

- Fixes #6841 
- In some case, the number of maximum storage buffers is `u32::MAX` which doesn't fit in a `i32`

## Solution

- Add an option to have a `u32` in a `ShaderDefVal`

f9ad051e61 Remove unnecessary alternate create_texture path in prepare_asset for Image (#6671)
# Objective

`prepare_asset` for Image has an alternate path for texture creation that is used when the image is not compressed and does not contain mipmaps. This additional code path is unnecessary as `render_device.create_texture_with_data()` will handle both cases correctly.

## Solution

Use `render_device.create_texture_with_data()` in all cases.

Tested successfully with the following examples:
- load_gltf
- render_to_texture
- texture
- 3d_shapes
- sprite
- sprite_sheet
- array_texture
- shader_material_screenspace_texture
- skybox (though this already would use the `create_texture_with_data()` branch anyway)

e954b8573c Lock down access to Entities (#6740)
# Objective
The soundness of the ECS `World` partially relies on the correctness of the state of `Entities` stored within it. We're currently allowing users to (unsafely) mutate it, as well as readily construct it without using a `World`. While this is not strictly unsound so long as users (including `bevy_render`) safely use the APIs, it's a fairly easy path to unsoundness without much of a guard rail.

Addresses #3362 for `bevy_ecs::entity`. Incorporates the changes from #3985.

## Solution
Remove `Entities`'s  `Default` implementation and force access to the type to only be through a properly constructed `World`.

Additional cleanup for other parts of `bevy_ecs::entity`:

 - `Entity::index` and `Entity::generation` are no longer `pub(crate)`, opting to force the rest of bevy_ecs to use the public interface to access these values.
 - `EntityMeta` is no longer `pub` and also not `pub(crate)` to attempt to cut down on updating `generation` without going through an `Entities` API. It's currently inaccessible except via the `pub(crate)` Vec on `Entities`, there was no way for an outside user to use it.
 - Added `Entities::set`, an unsafe `pub(crate)` API for setting the location of an Entity (parallel to `Entities::get`) that replaces the internal case where we need to set the location of an entity when it's been spawned, moved, or despawned.
 - `Entities::alloc_at_without_replacement` is only used in `World::get_or_spawn` within the first party crates, and I cannot find a public use of this API in any ecosystem crate that I've checked (via GitHub search).
 - Attempted to document the few remaining undocumented public APIs in the module.

---

## Changelog
Removed: `Entities`'s `Default` implementation.
Removed: `EntityMeta`
Removed: `Entities::alloc_at_without_replacement` and `AllocAtWithoutReplacement`.

9c79b39d73 set AVAILABLE_STORAGE_BUFFER_BINDINGS to the actual number of buffers available (#6787)
# Objective

- Since #5900 3d examples fail in wasm
```
ERROR crates/bevy_render/src/render_resource/pipeline_cache.rs:660 failed to process shader: Unknown shader def: 'AVAILABLE_STORAGE_BUFFER_BINDINGS'
```

## Solution

- Fix it by always adding the shaderdef `AVAILABLE_STORAGE_BUFFER_BINDINGS` with the actual value, instead of 3 when 3 or more were available

f119d9df8e Add DrawFunctionsInternals::id() (#6745)
# Objective

- Every usage of `DrawFunctionsInternals::get_id()` was followed by a `.unwrap()`. which just adds boilerplate.

## Solution

- Introduce a fallible version of `DrawFunctionsInternals::get_id()` and use it where possible.
- I also took the opportunity to improve the error message a little in the case where it fails.

---

## Changelog

- Added `DrawFunctionsInternals::id()`

64642fbd3c Remove unnecessary struct in Material AsBindGroup example (#6701)
# Objective

- Reduce confusion around uniform bindings in materials. I've seen multiple people on discord get confused by it because it uses a struct that is named the same in the rust code and the wgsl code, but doesn't contain the same data. Also, the only reason this works is mostly by chance because the memory happens to align correctly.

## Solution

- Remove the confusing parts of the doc

## Notes

It's not super clear in the diff why this causes confusion, but essentially, the rust code defines a `CustomMaterial` struct with a color and a texture, but in the wgsl code the struct with the same name only contains the color. People are confused by it because the struct in wgsl doesn't need to be there.

You _can_ have complex structs on each side and the macro will even combine it for you if you reuse a binding index, but as it is now, this example seems to confuse more than help people.

3827316100 bevy_reflect: Register missing reflected types for bevy_render (#6725)
# Objective 

Many types in `bevy_render` implemented `Reflect` but were not registered.

## Solution

Register all types in `bevy_render` that impl `Reflect`.

This also registers additional dependent types (i.e. field types).

> Note: Adding these dependent types would not be needed using something like #5781 😉 

---

## Changelog

- Register missing `bevy_render` types in the `TypeRegistry`:
  - `camera::RenderTarget`
  - `globals::GlobalsUniform`
  - `texture::Image`
  - `view::ComputedVisibility`
  - `view::Visibility`
  - `view::VisibleEntities`
- Register additional dependent types:
  - `view::ComputedVisibilityFlags`
  - `Vec<Entity>`

d44e86507f Shader defs can now have a value (#5900)
# Objective

- shaders defs can now have a `bool` or `int` value
- `#if SHADER_DEF <operator> 3`
  - ok if `SHADER_DEF` is defined, has the correct type and pass the comparison
  - `==`, `!=`, `>=`, `>`, `<`, `<=` supported
- `#SHADER_DEF` or `#{SHADER_DEF}`
  - will be replaced by the value in the shader code
---

## Migration Guide

- replace `shader_defs.push(String::from("NAME"));` by `shader_defs.push("NAME".into());`
- if you used shader def `NO_STORAGE_BUFFERS_SUPPORT`, check how `AVAILABLE_STORAGE_BUFFER_BINDINGS` is now used in Bevy default shaders

daa57fe489 Add try_* to add_slot_edge, add_node_edge (#6720)
# Objective

`add_node_edge` and `add_slot_edge` are fallible methods, but are always used with `.unwrap()`.
`input_node` is often unwrapped as well.
This points to having an infallible behaviour as default, with an alternative fallible variant if needed.

Improves readability and ergonomics.

## Solution

- Change `add_node_edge` and `add_slot_edge` to panic on error.
- Change `input_node` to panic on `None`.
- Add `try_add_node_edge` and `try_add_slot_edge` in case fallible methods are needed.
- Add `get_input_node` to still be able to get an `Option`.
---

## Changelog

### Added

- `try_add_node_edge`
- `try_add_slot_edge`
- `get_input_node`

### Changed

- `add_node_edge` is now infallible (panics on error)
- `add_slot_edge` is now infallible (panics on error)
- `input_node` now panics on `None`

## Migration Guide

Remove `.unwrap()` from `add_node_edge` and `add_slot_edge`.
For cases where the error was handled, use `try_add_node_edge` and `try_add_slot_edge` instead.

Remove `.unwrap()` from `input_node`.
For cases where the option was handled, use `get_input_node` instead.

174819be83 ExtractComponent output optional associated type (#6699)
# Objective

Allow more use cases where the user may benefit from both `ExtractComponentPlugin` _and_ `UniformComponentPlugin`.

## Solution

Add an associated type to `ExtractComponent` in order to allow specifying the output component (or bundle).

Make `extract_component` return an `Option<_>` such that components can be extracted only when needed.

What problem does this solve?

`ExtractComponentPlugin` allows extracting components, but currently the output type is the same as the input.
This means that use cases such as having a settings struct which turns into a uniform is awkward.

For example we might have:

```rust
struct MyStruct {
    enabled: bool,
    val: f32
}

struct MyStructUniform {
    val: f32
}
```

With the new approach, we can extract `MyStruct` only when it is enabled, and turn it into its related uniform.

This chains well with `UniformComponentPlugin`.

The user may then:

```rust
app.add_plugin(ExtractComponentPlugin::<MyStruct>::default());
app.add_plugin(UniformComponentPlugin::<MyStructUniform>::default());
```

This then saves the user a fair amount of boilerplate.


## Changelog

### Changed

- `ExtractComponent` can specify output type, and outputting is optional.

ed2ea0d417 The update_frame_count system should be placed in CorePlugin (#6676)
# Objective

Latest Release, "bevy 0.9" move the FrameCount updater into RenderPlugin, it leads to user who only run app with Core/Minimal Plugin cannot get the right number of FrameCount, it always return 0.

As for use cases like a server app, we don't want to add render dependencies to the app.

More detail in #6656

bdd5cee92a Add Box::from_corners method (#6672)
# Objective

This add a ctor to `Box` to aid the creation of non-centred boxes. The PR adopts @rezural's work on PR #3322, taking into account the feedback on that PR from @james7132.

## Solution

`Box::from_corners()` creates a `Box` from two opposing corners and automatically determines the min and max extents to ensure that the `Box` is well-formed.

2cd0bd7575 improve compile time by type-erasing wgpu structs (#5950)
# Objective

structs containing wgpu types take a long time to compile. this is particularly bad for generics containing the wgpu structs (like the depth pipeline builder with `#[derive(SystemParam)]` i've been working on).

we can avoid that by boxing and type-erasing in the bevy `render_resource` wrappers.

type system magic is not a strength of mine so i guess there will be a cleaner way to achieve this, happy to take feedback or for it to be taken as a proof of concept if someone else wants to do a better job.

## Solution

- add macros to box and type-erase in debug mode
- leave current impl for release mode

342f69e304 Shrink ComputedVisibility (#6305)
# Objective
`ComputedVisibility` could afford to be smaller/faster. Optimizing the size and performance of operations on the component will positively benefit almost all extraction systems.

This was listed as one of the potential pieces of future work for #5310.

## Solution
Merge both internal booleans into a single `u8` bitflag field. Rely on bitmasks to evaluate local, hierarchical, and general visibility.

Pros:

 - `ComputedVisibility::is_visible` should be a single bitmask test instead of two.
 - `ComputedVisibility` is now only 1 byte. Should be able to fit 100% more per cache line when using dense iteration.

Cons:

 - Harder to read.
 - Setting individual values inside `ComputedVisiblity` require bitmask mutations. 

This should be a non-breaking change. No public API was changed. The only publicly visible effect is that `ComputedVisibility` is now 1 byte instead of 2.

b765682c6e Add AutoMax next to ScalingMode::AutoMin (#6496)
# Objective

`ScalingMode::Auto` for cameras only targets min_height and min_width, or as the docs say it `Use minimal possible viewport size while keeping the aspect ratio.`

But there is no ScalingMode that targets max_height and Max_width or `Use maximal possible viewport size while keeping the aspect ratio.`

## Solution

Added `ScalingMode::AutoMax` that does the exact opposite of `ScalingMode::Auto`

---

## Changelog

Renamed `ScalingMode::Auto` to `ScalingMode::AutoMin`.

## Migration Guide

just rename `ScalingMode::Auto` to `ScalingMode::AutoMin` if you are using it.

ffa489a846 Ignore Timeout errors on Linux AMD & Intel (#5957)
# Objective

- Fix #3606
- Fix #4579
- Fix #3380

## Solution

When running on a Linux machine with some AMD or Intel device, when calling
`surface.get_current_texture()`, ignore `wgpu::SurfaceError::Timeout` errors.


## Alternative

An alternative solution found in the `wgpu` examples is:

```rust
let frame = surface
    .get_current_texture()
    .or_else(|_| {
        render_device.configure_surface(surface, &swap_chain_descriptor);
        surface.get_current_texture()
    })
    .expect("Error reconfiguring surface");
window.swap_chain_texture = Some(TextureView::from(frame));
```

See: <94ce76391b/wgpu/examples/framework.rs (L362-L370)>

Veloren [handles the Timeout error the way this PR proposes to handle it](https://github.com/gfx-rs/wgpu/issues/1218#issuecomment-1092056971).

The reason I went with this PR's solution is that `configure_surface` seems to be quite an expensive operation, and it would run every frame with the wgpu framework solution, despite the fact it works perfectly fine without `configure_surface`.

I know this looks super hacky with the linux-specific line and the AMD check, but my understanding is that the `Timeout` occurrence is specific to a quirk of some AMD drivers on linux, and if otherwise met should be considered a bug.

Still not super clear on whether this is a `naga` thing or an `encase` thing or what. But now that we're offering `globals` up to users and #5393 is not just breaking an example, maybe we should do this sort of workaround?

b6e46a73cd Rework ViewTarget to better support post processing (#6415)
# Objective

Post processing effects cannot read and write to the same texture. Currently they must own their own intermediate texture and redundantly copy from that back to the main texture. This is very inefficient.

Additionally, working with ViewTarget is more complicated than it needs to be, especially when working with HDR textures. 

## Solution

`ViewTarget` now stores two copies of the "main texture". It uses an atomic value to track which is currently the "main texture" (this interior mutability is necessary to accommodate read-only RenderGraph execution). 

`ViewTarget` now has a `post_process_write` method, which will return a source and destination texture. Each call to this method will flip between the two copies of the "main texture".

```rust
let post_process = render_target.post_process_write();
let source_texture = post_process.source;
let destination_texture = post_process.destination;
```
The caller _must_ read from the source texture and write to the destination texture, as it is assumed that the destination texture will become the new "main texture".


For simplicity / understandability `ViewTarget` is now a flat type. "hdr-ness" is a property of the `TextureFormat`. The internals are fully private in the interest of providing simple / consistent apis. Developers can now easily access the main texture by calling `view_target.main_texture()`.

HDR ViewTargets no longer have an "ldr texture" with `TextureFormat::bevy_default`. They _only_ have their two "hdr" textures. This simplifies the mental model.  All we have is the "currently active hdr texture" and the "other hdr texture", which we flip between for post processing effects.

The tonemapping node has been rephrased to use this "post processing pattern". The blit pass has been removed, and it now only runs a pass when HDR is enabled. Notably, both the input and output texture are assumed to be HDR. This means that tonemapping behaves just like any other "post processing effect". It could theoretically be moved anywhere in the "effect chain" and continue to work.

In general, I think these changes will make the lives of people making post processing effects much easier. And they better position us to start building higher level / more structured  "post processing effect stacks".

---

## Changelog

- `ViewTarget` now stores two copies of the "main texture". Calling `ViewTarget::post_process_write` will flip between copies of the main texture.

336049da68 Remove outdated uses of single-tuple bundles (#6406)
# Objective

Bevy still has many instances of using single-tuples `(T,)` to create a bundle. Due to #2975, this is no longer necessary.

## Solution

Search for regex `\(.+\s*,\)`. This should have found every instance.

e71c4d2802 fix nightly clippy warnings (#6395)
# Objective

- fix new clippy lints before they get stable and break CI

## Solution

- run `clippy --fix` to auto-fix machine-applicable lints
- silence `clippy::should_implement_trait` for `fn HandleId::default<T: Asset>`

## Changes
- always prefer `format!("{inline}")` over `format!("{}", not_inline)`
- prefer `Box::default` (or `Box::<T>::default` if necessary) over `Box::new(T::default())`

f867319336 add ReflectAsset and ReflectHandle (#5923)
# Objective
![image](https://user-images.githubusercontent.com/22177966/189350194-639a0211-e984-4f73-ae62-0ede44891eb9.png)

^ enable this

Concretely, I need to
- list all handle ids for an asset type
- fetch the asset as `dyn Reflect`, given a `HandleUntyped`
- when encountering a `Handle<T>`, find out what asset type that handle refers to (`T`'s type id) and turn the handle into a `HandleUntyped`

## Solution

- add `ReflectAsset` type containing function pointers for working with assets
```rust
pub struct ReflectAsset {
    type_uuid: Uuid,
    assets_resource_type_id: TypeId, // TypeId of the `Assets<T>` resource

    get: fn(&World, HandleUntyped) -> Option<&dyn Reflect>,
    get_mut: fn(&mut World, HandleUntyped) -> Option<&mut dyn Reflect>,
    get_unchecked_mut: unsafe fn(&World, HandleUntyped) -> Option<&mut dyn Reflect>,
    add: fn(&mut World, &dyn Reflect) -> HandleUntyped,
    set: fn(&mut World, HandleUntyped, &dyn Reflect) -> HandleUntyped,
    len: fn(&World) -> usize,
    ids: for<'w> fn(&'w World) -> Box<dyn Iterator<Item = HandleId> + 'w>,
    remove: fn(&mut World, HandleUntyped) -> Option<Box<dyn Reflect>>,
}
```
- add `ReflectHandle` type relating the handle back to the asset type and providing a way to create a `HandleUntyped`
```rust
pub struct ReflectHandle {
    type_uuid: Uuid,
    asset_type_id: TypeId,
    downcast_handle_untyped: fn(&dyn Any) -> Option<HandleUntyped>,
}
```
- add the corresponding `FromType` impls
- add a function `app.register_asset_reflect` which is supposed to be called after `.add_asset` and registers `ReflectAsset` and `ReflectHandle` in the type registry
---

## Changelog

- add `ReflectAsset` and `ReflectHandle` types, which allow code to use reflection to manipulate arbitrary assets without knowing their types at compile time

0401f04ba9 update camera projection if viewport changed (#5945)
fixes https://github.com/bevyengine/bevy/issues/5944

Uses the second solution:
> 2. keep track of the old viewport in the computed_state, and if camera.viewport != camera.computed_state.old_viewport, then update the projection. This is more reliable, but needs to store two UVec2s more in the camera (probably not a big deal).

456971381c Resolve most remaining execution-order ambiguities (#6341)
# Objective

Bevy's internal plugins have lots of execution-order ambiguities, which makes the ambiguity detection tool very noisy for our users.

## Solution

Silence every last ambiguity that can currently be resolved.
Each time an ambiguity is silenced, it is accompanied by a comment describing why it is correct. This description should be based on the public API of the respective systems. Thus, I have added documentation to some systems describing how they use some resources.

# Future work

Some ambiguities remain, due to issues out of scope for this PR. 

* The ambiguity checker does not respect `Without<>` filters, leading to false positives.
* Ambiguities between `bevy_ui` and `bevy_animation` cannot be resolved, since neither crate knows that the other exists. We will need a general solution to this problem.

4d3d3c869e Support arbitrary RenderTarget texture formats (#6380)
# Objective

Currently, Bevy only supports rendering to the current "surface texture format". This means that "render to texture" scenarios must use the exact format the primary window's surface uses, or Bevy will crash. This is even harder than it used to be now that we detect preferred surface formats at runtime instead of using hard coded BevyDefault values.

## Solution

1. Look up and store each window surface's texture format alongside other extracted window information
2. Specialize the upscaling pass on the current `RenderTarget`'s texture format, now that we can cheaply correlate render targets to their current texture format
3. Remove the old `SurfaceTextureFormat` and `AvailableTextureFormats`: these are now redundant with the information stored on each extracted window, and probably should not have been globals in the first place (as in theory each surface could have a different format). 

This means you can now use any texture format you want when rendering to a texture! For example, changing the `render_to_texture` example to use `R16Float` now doesn't crash / properly only stores the red component:

838b318863 separate tonemapping and upscaling passes (#3425)
Attempt to make features like bloom https://github.com/bevyengine/bevy/pull/2876 easier to implement.

**This PR:**
- Moves the tonemapping from `pbr.wgsl` into a separate pass
- also add a separate upscaling pass after the tonemapping which writes to the swap chain (enables resolution-independant rendering and post-processing after tonemapping)
- adds a `hdr` bool to the camera which controls whether the pbr and sprite shaders render into a `Rgba16Float` texture

**Open questions:**
- ~should the 2d graph work the same as the 3d one?~ it is the same now
- ~The current solution is a bit inflexible because while you can add a post processing pass that writes to e.g. the `hdr_texture`, you can't write to a separate `user_postprocess_texture` while reading the `hdr_texture` and tell the tone mapping pass to read from the `user_postprocess_texture` instead. If the tonemapping and upscaling render graph nodes were to take in a `TextureView` instead of the view entity this would almost work, but the bind groups for their respective input textures are already created in the `Queue` render stage in the hardcoded order.~ solved by creating bind groups in render node

**New render graph:**

5622d56be1 Use plugin setup for resource only used at setup time (#6360)
# Objective

- Build on #6336 for more plugin configurations

## Solution

- `LogSettings`, `ImageSettings` and `DefaultTaskPoolOptions` are now plugins settings rather than resources

---

## Changelog

- `LogSettings` plugin settings have been move to `LogPlugin`, `ImageSettings` to `ImagePlugin` and `DefaultTaskPoolOptions` to `CorePlugin`

## Migration Guide

The `LogSettings` settings have been moved from a resource to `LogPlugin` configuration:

```rust
// Old (Bevy 0.8)
app
  .insert_resource(LogSettings {
    level: Level::DEBUG,
    filter: "wgpu=error,bevy_render=info,bevy_ecs=trace".to_string(),
  })
  .add_plugins(DefaultPlugins)

// New (Bevy 0.9)
app.add_plugins(DefaultPlugins.set(LogPlugin {
    level: Level::DEBUG,
    filter: "wgpu=error,bevy_render=info,bevy_ecs=trace".to_string(),
}))
```


The `ImageSettings` settings have been moved from a resource to `ImagePlugin` configuration:

```rust
// Old (Bevy 0.8)
app
  .insert_resource(ImageSettings::default_nearest())
  .add_plugins(DefaultPlugins)

// New (Bevy 0.9)
app.add_plugins(DefaultPlugins.set(ImagePlugin::default_nearest()))
```


The `DefaultTaskPoolOptions` settings have been moved from a resource to `CorePlugin::task_pool_options`:

```rust
// Old (Bevy 0.8)
app
  .insert_resource(DefaultTaskPoolOptions::with_num_threads(4))
  .add_plugins(DefaultPlugins)

// New (Bevy 0.9)
app.add_plugins(DefaultPlugins.set(CorePlugin {
  task_pool_options: TaskPoolOptions::with_num_threads(4),
}))

3c13c75036 Optimize rendering slow-down at high entity counts (#5509)
# Objective

- Improve #3953

## Solution

- The very specific circumstances under which the render world is reset meant that the flush_as_invalid function could be replaced with one that had a noop as its init method.
- This removes a double-writing issue leading to greatly increased performance.

Running the reproduction code in the linked issue, this change nearly doubles the framerate.

3689d5d086 Avoid creating SurfaceConfiguration in prepare_windows (#6255)
# Objective

- Avoids creating a `SurfaceConfiguration` for every window in every frame for the `prepare_windows` system
- As such also avoid calling `get_supported_formats` for every window in every frame

## Solution

- Construct `SurfaceConfiguration` lazyly in `prepare_windows`

7989cb2650 Add global time scaling (#5752)
# Objective

- Make `Time` API more consistent.
- Support time accel/decel/pause.

## Solution

This is just the `Time` half of #3002. I was told that part isn't controversial.

- Give the "delta time" and "total elapsed time" methods `f32`, `f64`, and `Duration` variants with consistent naming.
- Implement accelerating / decelerating the passage of time.
- Implement stopping time.

---

## Changelog

- Changed `time_since_startup` to `elapsed` because `time.time_*` is just silly.
- Added `relative_speed` and `set_relative_speed` methods.
- Added `is_paused`, `pause`, `unpause` , and methods. (I'd prefer `resume`, but `unpause` matches `Timer` API.)
- Added `raw_*` variants of the "delta time" and "total elapsed time" methods.
- Added `first_update` method because there's a non-zero duration between startup and the first update.

## Migration Guide

- `time.time_since_startup()` -> `time.elapsed()`
- `time.seconds_since_startup()` -> `time.elapsed_seconds_f64()`
- `time.seconds_since_startup_wrapped_f32()` -> `time.elapsed_seconds_wrapped()`

If you aren't sure which to use, most systems should continue to use "scaled" time (e.g. `time.delta_seconds()`). The realtime "unscaled" time measurements (e.g. `time.raw_delta_seconds()`) are mostly for debugging and profiling.

## Changelog

### Changed

- Changed `RawWindowHandleWrapper` to `RawHandleWrapper` which wraps both `RawWindowHandle` and `RawDisplayHandle`, which satisfies the `impl HasRawWindowHandle and HasRawDisplayHandle` that `wgpu` 0.14.0 requires.

- Changed `bevy_window::WindowDescriptor`'s `cursor_locked` to `cursor_grab_mode`, change its type from `bool` to `bevy_window::CursorGrabMode`.

## Migration Guide

- Adjust usage of `bevy_window::WindowDescriptor`'s `cursor_locked` to `cursor_grab_mode`, and adjust its type from `bool` to `bevy_window::CursorGrabMode`.
