56b0e88b53 Add view transform to view uniform (#3885)
(cherry picked from commit de943381bd2a8b242c94db99e6c7bbd70006d7c3)

# Objective

The view uniform lacks view transform information. The inverse transform is currently provided but this is not sufficient if you do not have access to an `inverse` function (such as in WGSL).

## Solution

Grab the view transform, put it in the view uniform, use the same matrix to compute the inverse as well.

f7478f448a doc: remove mention of void return type in entry_point docs (#3881)
# Objective

The docs for `{VertexState, FragmentState}::entry_point` stipulate that the entry point function in the shader must return void. This seems to be specific to GLSL; WGSL has no `void` type and its entry point functions return values that describe their output.

## Solution

Remove the mention of the `void` return type.

1477765f62 Replace VSync with PresentMode (#3812)
# Objective

Enable the user to specify any presentation modes (including `Mailbox`).

Fixes #3807

## Solution

I've added a new `PresentMode` enum in `bevy_window` that mirrors the `wgpu` enum 1:1. Alternatively, I could add a new dependency on `wgpu-types` if that would be preferred.

b7dfe1677f include sources in shader validation error (#3724)
## Objective

When print shader validation error messages, we didn't print the sources and error message text, which led to some confusing error messages.

```cs
error: 
   ┌─ wgsl:15:11
   │
15 │     return material.color + 1u;
   │           ^^^^^^^^^^^^^^^^^^^^ naga::Expression [11]
```

## Solution

New error message:
```cs
error: Entry point fragment at Vertex is invalid
   ┌─ wgsl:15:11
   │
15 │     return material.color + 1u;
   │           ^^^^^^^^^^^^^^^^^^^^ naga::Expression [11]
   │
   = Expression [11] is invalid
   = Operation Add can't work with [8] and [10]

33ef5b5039 bevy_render: Only auto-disable mappable primary buffers for discrete GPUs (#3803)
# Objective

- While it is not safe to enable mappable primary buffers for all GPUs, it should be preferred for integrated GPUs where an integrated GPU is one that is sharing system memory.

## Solution

- Auto-disable mappable primary buffers only for discrete GPUs. If the GPU is integrated and mappable primary buffers are supported, use them.

ca029ef0eb Naga export (#3714)
# Objective

In order to create a glsl shader, we must provide the `naga::ShaderStage` type which is not exported by bevy, meaning a user would have to manually include naga just to access this type.

`pub fn from_glsl(source: impl Into<Cow<'static, str>>, stage: naga::ShaderStage) -> Shader {`

## Solution

Re-rexport naga::ShaderStage from `render_resources`

55da315432 bevy_render: Provide a way to opt-out of the built-in frustum culling (#3711)
# Objective

- Allow opting-out of the built-in frustum culling for cases where its behaviour would be incorrect
- Make use of the this in the shader_instancing example that uses a custom instancing method. The built-in frustum culling breaks the custom instancing in the shader_instancing example if the camera is moved to:

```rust
    commands.spawn_bundle(PerspectiveCameraBundle {
        transform: Transform::from_xyz(12.0, 0.0, 15.0)
            .looking_at(Vec3::new(12.0, 0.0, 0.0), Vec3::Y),
        ..Default::default()
    });
```

...such that the Aabb of the cube Mesh that is at the origin goes completely out of view. This incorrectly (for the purpose of the custom instancing) culls the `Mesh` and so culls all instances even though some may be visible.


## Solution

- Add a `NoFrustumCulling` marker component
- Do not compute and add an `Aabb` to `Mesh` entities without an `Aabb` if they have a `NoFrustumCulling` marker component
- Do not apply frustum culling to entities with the `NoFrustumCulling` marker component

ef823d369f bevy_render: Do not automatically enable MAPPABLE_PRIMARY_BUFFERS (#3698)
# Objective

- When using `WgpuOptionsPriority::Functionality`, which is the default, wgpu::Features::MAPPABLE_PRIMARY_BUFFERS would be automatically enabled. This feature can and does have a significant negative impact on performance for discrete GPUs where resizable bar is not supported, which is a common case. As such, this feature should not be automatically enabled.
- Fixes the performance regression part of https://github.com/bevyengine/bevy/issues/3686 and at least some, if not all cases of https://github.com/bevyengine/bevy/issues/3687

## Solution

- When using `WgpuOptionsPriority::Functionality`, use the adapter-supported features, enable `TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES` and disable `MAPPABLE_PRIMARY_BUFFERS`

d11cd63452 Fixed doc comment with render Node input/output methods (#3642)
Fixed doc comment where render Node input/output methods refered to using `RenderContext` for interaction instead of `RenderGraphContext`

# Objective

130953c717 Enable the doc_markdown clippy lint (#3457)
# Objective

CI should check for missing backticks in doc comments.

Fixes #3435

## Solution

`clippy` has a lint for this: `doc_markdown`. This enables that lint in the CI script.

Of course, enabling this lint in CI causes a bunch of lint errors, so I've gone through and fixed all of them. This was a huge edit that touched a ton of files, so I split the PR up by crate.

When all of the following are merged, the CI should pass and this can be merged.

c2da7800e3 Add 2d meshes and materials (#3460)
# Objective

The current 2d rendering is specialized to render sprites, we need a generic way to render 2d items, using meshes and materials like we have for 3d.

## Solution

I cloned a good part of `bevy_pbr` into `bevy_sprite/src/mesh2d`, removed lighting and pbr itself, adapted it to 2d rendering, added a `ColorMaterial`, and modified the sprite rendering to break batches around 2d meshes.

~~The PR is a bit crude; I tried to change as little as I could in both the parts copied from 3d and the current sprite rendering to make reviewing easier. In the future, I expect we could make the sprite rendering a normal 2d material, cleanly integrated with the rest.~~ _edit: see <https://github.com/bevyengine/bevy/pull/3460#issuecomment-1003605194>_

## Remaining work

- ~~don't require mesh normals~~ _out of scope_
- ~~add an example~~ _done_
- support 2d meshes & materials in the UI?
- bikeshed names (I didn't think hard about naming, please check if it's fine)

## Remaining questions

- ~~should we add a depth buffer to 2d now that there are 2d meshes?~~ _let's revisit that when we have an opaque render phase_
- ~~should we add MSAA support to the sprites, or remove it from the 2d meshes?~~ _I added MSAA to sprites since it's really needed for 2d meshes_
- ~~how to customize vertex attributes?~~ _#3120_

b9c623e4f3 Configurable wgpu features/limits priority (#3452)
# Objective

- Allow the user to specify the priority when configuring wgpu features/limits and by default use the maximum capabilities of the chosen adapter.

## Solution

- Add a `WgpuOptionsPriority` enum with `Compatibility`, `Functionality` and `WebGL2` options.
- Add a `priority: WgpuOptionsPriority` member to `WgpuOptions`.
- When initialising the renderer, if `WgpuOptions::priority == WgpuOptionsPriority::Functionality`, query the adapter for the available features and limits, use them when creating a device, and update `WgpuOptions` with those values. If `Compatibility` use the behaviour as before this PR. If `WebGL2` then use the WebGL2 downlevel limits as used when when building for wasm, for convenience of testing WebGL2 limits without having to build for wasm.
- Add an environment variable `WGPU_OPTIONS_PRIO` that takes `compatibility`, `functionality`, `webgl2`.
- Default to `WgpuOptionsPriority::Functionality`.
- Insert updated `WgpuOptions` into render app world as well. This is useful for applying the limits when rendering, such as limiting the directional light shadow map texture to 2048x2048 when using WebGL2 downlevel limits but not on wasm.
- Reduced `draw_state` logs from `debug` to `trace` and added `debug` level logs for the wgpu features and limits. Use `RUST_LOG=bevy_render=debug` to see the output.

85b7589388 bevy_gltf: Add support for loading lights (#3506)
# Objective

## Solution

- This adds support for the KHR_punctual_lights extension which supports point, directional, and spot lights, though we don't yet support spot lights.
- Inserting light bundles when creating scenes required registering some more light bundle component types.

dc8fefe27f Remove Bytes, FromBytes, Labels, EntityLabels. Document rest of bevy_core and enable warning on missing docs. (#3521)
This PR is part of the issue #3492.

# Objective

 - Clean up dead code in `bevy_core`.
 - Add and update the `bevy_core` documentation to achieve a 100% documentation coverage.
 - Add the #![warn(missing_docs)] lint to keep the documentation coverage for the future.

# Solution

 - Remove unused `Bytes`, `FromBytes`, `Labels`, and `EntityLabels` types and associated systems.
 - Made several types private that really only have use as internal types, mostly pertaining to fixed timestep execution.
 - Add and update the bevy_core documentation.
 - Add the #![warn(missing_docs)] lint.

# Open Questions

Should more of the internal states of `FixedTimestep` be public? Seems mostly to be an implementation detail unless someone really needs that fixed timestep state.

db68704231 Enable Msaa for webgl by default (#3489)
# Objective

- `Msaa` was disabled in webgl due to a bug in wgpu
- Bug has been fixed (https://github.com/gfx-rs/wgpu/pull/2307) and backported (https://github.com/gfx-rs/wgpu/pull/2327), and updates for [`wgpu-core`](https://crates.io/crates/wgpu-core/0.12.1) and [`wgpu-hal`](https://crates.io/crates/wgpu-hal/0.12.1) have been released

## Solution

- Remove custom config for `Msaa` in webgl
- I also changed two options that were using the arch instead of the `webgl` feature. it shouldn't change much for webgl, but could help if someone wants to target wasm but not webgl2

06d9384447 Add FromReflect trait to convert dynamic types to concrete types (#1395)
Dynamic types (`DynamicStruct`, `DynamicTupleStruct`, `DynamicTuple`, `DynamicList` and `DynamicMap`) are used when deserializing scenes, but currently they can only be applied to existing concrete types. This leads to issues when trying to spawn non trivial deserialized scene.
For components, the issue is avoided by requiring that reflected components implement ~~`FromResources`~~ `FromWorld` (or `Default`). When spawning, a new concrete type is created that way, and the dynamic type is applied to it. Unfortunately, some components don't have any valid implementation of these traits.
In addition, any `Vec` or `HashMap` inside a component will panic when a dynamic type is pushed into it (for instance, `Text` panics when adding a text section).

To solve this issue, this PR adds the `FromReflect` trait that creates a concrete type from a dynamic type that represent it, derives the trait alongside the `Reflect` trait, drops the ~~`FromResources`~~ `FromWorld` requirement on reflected components, ~~and enables reflection for UI and Text bundles~~. It also adds the requirement that fields ignored with `#[reflect(ignore)]` implement `Default`, since we need to initialize them somehow.

76ec709ede Add Visibility component to UI (#3426)
# Objective

Fixes #3422 

## Solution

Adds the existing `Visibility` component to UI bundles and checks for it in the extract phase of the render app.

The `ComputedVisibility` component was not added. I don't think the UI camera needs frustum culling, but having `RenderLayers` work may be desirable. However I think we would need to change `check_visibility()` to differentiate between 2d, 3d and UI entities.

79d36e7c28 Prepare crevice for vendored release (#3394)
# Objective

- Our crevice is still called "crevice", which we can't use for a release
- Users would need to use our "crevice" directly to be able to use the derive macro

## Solution

- Rename crevice to bevy_crevice, and crevice-derive to bevy-crevice-derive
- Re-export it from bevy_render, and use it from bevy_render everywhere
- Fix derive macro to work either from bevy_render, from bevy_crevice, or from bevy

## Remaining

- It is currently re-exported as `bevy::render::bevy_crevice`, is it the path we want?
- After a brief suggestion to Cart, I changed the version to follow Bevy version instead of crevice, do we want that?
- Crevice README.md need to be updated
- in the `Cargo.toml`, there are a few things to change. How do we want to change them? How do we keep attributions to original Crevice?

081350916c report shader processing errors in RenderPipelineCache (#3289)
### Problem
- shader processing errors are not displayed
- during hot reloading when encountering a shader with errors, the whole app crashes

### Solution
- log `error!`s for shader processing errors 
- when `cfg(debug_assertions)` is enabled (i.e. you're running in `debug` mode), parse shaders before passing them to wgpu. This lets us handle errors early.

6c479649bf enable Webgl2 optimisation in pbr under feature (#3291)
# Objective

- 3d examples fail to run in webgl2 because of unsupported texture formats or texture too large

## Solution

- switch to supported formats if a feature is enabled. I choose a feature instead of a build target to not conflict with a potential webgpu support

Very inspired by 6813b2edc5, and need #3290 to work.

I named the feature `webgl2`, but it's only needed if one want to use PBR in webgl2. Examples using only 2D already work.

73f524f61c Support topologies other than TriangleList (#3349)
# Objective

Fixes https://github.com/bevyengine/bevy/issues/3346

## Solution

I've encoded the topology in the `MeshKey` similar to how MSAA samples are handled.

6a0008f3d3 Fix doc warnings (#3339)
# Objective

- There are a few warnings when building Bevy docs for dead links
- CI seems to not catch those warnings when it should

## Solution

- Enable doc CI on all Bevy workspace
- Fix warnings
- Also noticed plugin GilrsPlugin was not added anymore when feature was enabled


First commit to check that CI would actually fail with it: https://github.com/bevyengine/bevy/runs/4532652688?check_suite_focus=true

9a16a4d018 Added set_scissor_rect to tracked render pass. (#3320)
# Objective And Solution
Add `set_scissor_rect` from wgpu-rs to the `TrackedRenderPass`. wgpu documentation can be found here:
https://docs.rs/wgpu/latest/wgpu/struct.RenderPass.html#method.set_scissor_rect

The reason for adding this is to cull fragments that are outside of the given rect. For my purposes this is extremely useful for UI.

ffecb05a0a Replace old renderer with new renderer (#3312)
This makes the [New Bevy Renderer](#2535) the default (and only) renderer. The new renderer isn't _quite_ ready for the final release yet, but I want as many people as possible to start testing it so we can identify bugs and address feedback prior to release.

The examples are all ported over and operational with a few exceptions:

* I removed a good portion of the examples in the `shader` folder. We still have some work to do in order to make these examples possible / ergonomic / worthwhile: #3120 and "high level shader material plugins" are the big ones. This is a temporary measure.
* Temporarily removed the multiple_windows example: doing this properly in the new renderer will require the upcoming "render targets" changes. Same goes for the render_to_texture example.
* Removed z_sort_debug: entity visibility sort info is no longer available in app logic. we could do this on the "render app" side, but i dont consider it a priority.
