Fix Gizmos warnings and doc errors when a subset of features are selected (#14887)
# Objective

When trying to test a gizmos change I ran `cargo test -p bevy_gizmos`
and the output had a lot of noise from warnings and failed doc errors.
This was because I didn't have all of the features enabled.

## Solution

I admit this might be pedantic, and am happy if the concensus is to
reject it. Although it does reduce the lines of code, testing noise, and
the amount of code compiled. I don't think it affects the complexity of
public code, and it doesn't change much to the complexity of internal
code.

I've removed un-needed `bevy_render` imports in all of the gizmos docs
examples, there's probably other unnecessary ones there too, but I
haven't looked exhaustively. It isn't needed for those docs, and isn't
available except in a subset of `cfg` combinations.

I've also made several of the `use` statements slightly more specific. I
shouldn't have changed the public interfaces, except that
`GizmoMeshConfig` requires either `bevy_sprite` or `bevy_pbr`, as it
does nothing without them.

I've also avoided adding some systems and plugins in situations where
they can't work. An example of this is where the `light` module depends
on `all(feature = "bevy_pbr", feature = "bevy_render")`, but it has
`use` statements that only require `bevy_render`.

## Testing

During development I ran:
```
cargo check -p bevy_gizmos && cargo check -p bevy_gizmos --features=bevy_pbr && cargo check -p bevy_gizmos --features=bevy_sprite && cargo check -p bevy_gizmos --features=bevy_render
```
Afterwards I ran this just to be sure:
```
cargo check && cargo check --features=bevy_pbr && cargo check --features=bevy_sprite && cargo check --features=bevy_render
```

Finally I ran:
```
cargo test -p bevy_gizmos && cargo test -p bevy_gizmos --features=bevy_pbr && test check -p bevy_gizmos --features=bevy_sprite && cargo test -p bevy_gizmos --features=bevy_render
```

## Migration Guide

There shouldn't be any reason to migrate, although if for some reason
you use `GizmoMeshConfig` and `bevy_render` but not `bevy_pbr` or
`bevy_sprite` (such that it does nothing), then you will get an error
that it no longer exists.

What is Bevy?

Bevy is a refreshingly simple data-driven game engine built in Rust. It is free and open-source forever!

WARNING

Bevy is still in the early stages of development. Important features are missing. Documentation is sparse. A new version of Bevy containing breaking changes to the API is released approximately once every 3 months. We provide migration guides, but we can't guarantee migrations will always be easy. Use only if you are willing to work in this environment.

MSRV: Bevy relies heavily on improvements in the Rust language and compiler. As a result, the Minimum Supported Rust Version (MSRV) is generally close to "the latest stable release" of Rust.

Design Goals

  • Capable: Offer a complete 2D and 3D feature set
  • Simple: Easy for newbies to pick up, but infinitely flexible for power users
  • Data Focused: Data-oriented architecture using the Entity Component System paradigm
  • Modular: Use only what you need. Replace what you don't like
  • Fast: App logic should run quickly, and when possible, in parallel
  • Productive: Changes should compile quickly ... waiting isn't fun

About

  • Features: A quick overview of Bevy's features.
  • News: A development blog that covers our progress, plans and shiny new features.

Community

Before contributing or participating in discussions with the community, you should familiarize yourself with our Code of Conduct.

  • Discord: Bevy's official discord server.
  • Reddit: Bevy's official subreddit.
  • GitHub Discussions: The best place for questions about Bevy, answered right here!
  • Bevy Assets: A collection of awesome Bevy projects, tools, plugins and learning materials.

Contributing

If you'd like to help build Bevy, check out the Contributor's Guide. For simple problems, feel free to open an issue or PR and tackle it yourself!

For more complex architecture decisions and experimental mad science, please open an RFC (Request For Comments) so we can brainstorm together effectively!

Getting Started

We recommend checking out the Quick Start Guide for a brief introduction.

Follow the Setup guide to ensure your development environment is set up correctly. Once set up, you can quickly try out the examples by cloning this repo and running the following commands:

# Switch to the correct version (latest release, default is main development branch)
git checkout latest
# Runs the "breakout" example
cargo run --example breakout

To draw a window with standard functionality enabled, use:

use bevy::prelude::*;

fn main(){
  App::new()
    .add_plugins(DefaultPlugins)
    .run();
}

Fast Compiles

Bevy can be built just fine using default configuration on stable Rust. However for really fast iterative compiles, you should enable the "fast compiles" setup by following the instructions here.

Bevy Cargo Features

This list outlines the different cargo features supported by Bevy. These allow you to customize the Bevy feature set for your use-case.

Thanks

Bevy is the result of the hard work of many people. A huge thanks to all Bevy contributors, the many open source projects that have come before us, the Rust gamedev ecosystem, and the many libraries we build on.

A huge thanks to Bevy's generous sponsors. Bevy will always be free and open source, but it isn't free to make. Please consider sponsoring our work if you like what we're building.

This project is tested with BrowserStack.

License

Bevy is free, open source and permissively licensed! Except where noted (below and/or in individual files), all code in this repository is dual-licensed under either:

at your option. This means you can select the license you prefer! This dual-licensing approach is the de-facto standard in the Rust ecosystem and there are very good reasons to include both.

Some of the engine's code carries additional copyright notices and license terms due to their external origins. These are generally BSD-like, but exact details vary by crate: If the README of a crate contains a 'License' header (or similar), the additional copyright notices and license terms applicable to that crate will be listed. The above licensing requirement still applies to contributions to those crates, and sections of those crates will carry those license terms. The license field of each crate will also reflect this. For example, bevy_mikktspace has code under the Zlib license (as well as a copyright notice when choosing the MIT license).

The assets included in this repository (for our examples) typically fall under different open licenses. These will not be included in your game (unless copied in by you), and they are not distributed in the published bevy crates. See CREDITS.md for the details of the licenses of those files.

Your contributions

Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
