-# Contribution Guidelines
+# Winit Contributing Guidelines
 
-This document contains guidelines for contributing code to winit. It has to be
-followed in order for your patch to be approved and applied.
+## Scope
+[See `FEATURES.md`](./FEATURES.md). When requesting or implementing a new Winit feature, you should
+consider whether or not it's directly related to window creation or input handling. If it isn't, it
+may be worth creating a separate crate that extends Winit's API to add that functionality.
 
-## Contributing
 
-Anyone can contribute to winit, however given that it's a cross platform
-windowing toolkit getting certain changes incorporated could be challenging.
+## Reporting an issue
 
-To save your time it's wise to check already opened [pull requests][prs] and
-[issues][issues]. In general, bug fixes and missing implementations are always
-accepted, however larger new API proposals should go into the issue first. When
-in doubt contact us on [Matrix][matrix] or via opening an issue.
+When reporting an issue, in order to help the maintainers understand what the problem is, please make
+your description of the issue as detailed as possible:
 
-### Windows
+- if it is a bug, please provide clear explanation of what happens, what should happen, and how to
+  reproduce the issue, ideally by providing a minimal program exhibiting the problem
+- if it is a feature request, please provide a clear argumentation about why you believe this feature
+  should be supported by winit
 
-To run the examples on Windows, you must have symlinks enabled, see
-[this][git-windows-symlinks].
+## Making a pull request
 
-[git-windows-symlinks]: https://gitforwindows.org/symbolic-links.html
+When making a code contribution to winit, before opening your pull request, please make sure that:
 
-### Submitting your work and handling review
+- your patch builds with Winit's minimal supported rust version - Rust 1.64.
+- you tested your modifications on all the platforms impacted, or if not possible detail which platforms
+  were not tested, and what should be tested, so that a maintainer or another contributor can test them
+- you updated any relevant documentation in winit
+- you left comments in your code explaining any part that is not straightforward, so that the
+  maintainers and future contributors don't have to try to guess what your code is supposed to do
+- your PR adds an entry to the changelog file if the introduced change is relevant to winit users.
 
-All patches have to be sent on Github as [pull requests][prs]. To simplify your
-life during review it's recommended to check the "give contributors write access
-to the branch" checkbox.
+  You needn't worry about the added entry causing conflicts, the maintainer that merges the PR will
+  handle those for you when merging (see below).
+- if your PR affects the platform compatibility of one or more features or adds another feature, the
+  relevant sections in [`FEATURES.md`](https://github.com/rust-windowing/winit/blob/master/FEATURES.md#features)
+  should be updated.
 
-We use unstable Rustfmt options across the project, so please run
-`cargo +nightly fmt` before submitting your work. If you are unable to do so,
-the maintainers can do it for you before merging, just state so in your pull
-request description. For details on how to use nightly, consult [the
-documentation][toolchains].
+Once your PR is open, you can ask for review by a maintainer of your platform. Winit's merging policy
+is that a PR must be approved by at least two maintainers of winit before being merged, including
+at least a maintainer of the platform (a maintainer making a PR themselves counts as approving it).
 
-When editing markdown files (`.md`) they must be wrapped at 80 characters.
+Once your PR is deemed ready, the merging maintainer will take care of resolving conflicts in
+`CHANGELOG.md` (but you must resolve other conflicts yourself). Doing this requires that you check the
+"give contributors write access to the branch" checkbox when creating the PR.
 
-[toolchains]: https://rust-lang.github.io/rustup/concepts/toolchains.html
+## Maintainers & Testers
 
-#### Handling review
+The current maintainers are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
 
-During the review process certain events could require an action from your side,
-common patterns and reactions are described below.
+If you are interested in being pinged when testing is needed for a certain platform, please add yourself to the [Testers and Contributors](https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors) table!
 
-_Event:_ The CI fails to build, but it looks like it is not your fault. Not
-communicating so could result in maintainers not looking into your patch,
-since they may assume that you're still working on it.\
-_Desired behaviour:_ Write a message saying roughly the following "The CI
-failure is unrelated", so that the maintainers will fix it for you.
+## Release process
 
-_Event:_ Maintainer requested changes to your PR.\
-_Desired behavior:_ Once you address the request, you should re-request a review
-with GitHub's UI. If you don't agree with what maintainer suggested, you
-should state your objections and re-request the review. That will indicate that
-the ball is on maintainer's side.
-
-_Event:_ You've opened a PR, but maintainer shortly after commented that they
-want to work on that themselves.\
-_Desired behavior:_ Discuss with the maintainer regarding their plans if they
-were not outlined in the initial response, because such response means that they
-are not interested in reviewing your code. Such thing could happen when
-underestimating complexity of the task you're solving or when your patch
-mandate certain downstream designs. In general, the maintainer will likely
-close your PR in order to prevent work being done on it.

-## Maintainers
-
-Winit has plenty of maintainers with different backgrounds, different time
-available to work on Winit, and reasons to be winit maintainer in the first
-place. To ensure that Winit's code quality does not decrease over time and to
-make it easier to teach new maintainers the "winit way of doing things" the
-common policies and routines are defined in this section.
-
-The current maintainers for each platform are listed in [this file][CODEOWNERS].
-
-### Contributions handling
-
-The maintainers must ensure that the external contributions meet Winit's
-quality standards. If it's not, it **is the maintainer's responsibility** to
-bring it on par, which includes:
-
-  - Ensure that formatting is consistent and `CHANGELOG` messages are clear
-    for the end users.
-  - Improve the commit message, so it'll be easier for other maintainers to
-    understand the motivation without going through all the discussions on the
-    particular patch/PR.
-  - Ensure that the proposed patch doesn't break platform parity. If the
-    breakage is desired by contributor, an issue should be opened to discuss
-    with other maintainers before merging.
-  - Always fix CI issues before merging if they don't originate from the
-    submitted work.
-
-However, maintainers should give some leeway for external contributors, so they
-don't feel discouraged contributing, for example:
-
-  - Suggest a patch to resolve style issues, if it's the only issue with the
-    submitted work. Keep in mind that pushing the resolution yourself is not
-    desired, because the contributor might not agree with what you did.
-  - Be more explicit on how things should be done if you don't like the
-    approach.
-  - Suggest to finish the PR for them if they're absent for a while and you need
-    the proposed changes to move forward with something. In such cases the
-    maintainer must preserve attribution with `Co-authored-by`, `Suggested-by`,
-    or keep the original committer.
-  - Rebase their work for them when massive changes to the Winit codebase were
-    introduced.
-
-When reviewing code of other maintainers all of the above is on the maintainer
-who submitted the patch. Interested maintainers could help push the work over
-the finish line, but teaching other maintainers should be preferred.
-
-For a _regular_ contributor to winit, the maintainer should slowly start
-requiring contributor to match *maintainer* quality standards when writing
-patches and commit messages.
-
-### Contributing
-
-When submitting a patch, the maintainer should follow the general contributing
-guidelines, however greater attention to detail is expected in this case.
-
-To make life simpler for other maintainers it's suggested to create your branch
-under the project repository instead of your own fork. The naming scheme is
-`github_user_name/branch_name`. Doing so will make your work easier to rebase
-for other maintainers when you're absent.
-
-### Administrative Actions
-
-Some things (such as changing required CI steps, adding contributors, ...)
-require administrative permissions. If you don't have those, ask about the
-change in an issue. If you have the permissions, discuss it with at least one
-other admin before making the change.
-
-### Release process
-
-Given that winit is a widely used library, we should be able to make a patch
+Given that winit is a widely used library we should be able to make a patch
 releases at any time we want without blocking the development of new features.
 
 To achieve these goals, a new branch is created for every new release. Releases
 and later patch releases are committed and tagged in this branch.
 
 The exact steps for an exemplary `0.2.0` release might look like this:
-  1. Initially, the version on the latest master is `0.1.0`
+  1. Initially the version on the latest master is `0.1.0`
   2. A new `v0.2.x` branch is created for the release
-  3. Update released `cfg_attr` in `src/changelog/mod.rs` to `v0.2.md`
-  4. Move entries from `src/changelog/unreleased.md` into
-     `src/changelog/v0.2.md`
-  5. In the branch, the version is bumped to `v0.2.0`
-  6. The new commit in the branch is tagged `v0.2.0`
-  7. The version is pushed to crates.io
-  8. A GitHub release is created for the `v0.2.0` tag
-  9. On master, the version is bumped to `0.2.0`, and the changelog is updated
-

-  1. Initially, the version of the latest release is `0.2.0`
+  3. In the branch, the version is bumped to `v0.2.0`
+  4. The new commit in the branch is tagged `v0.2.0`

+When doing a patch release the process is similar:
+  1. Initially the version of the latest release is `0.2.0`
   2. Checkout the `v0.2.x` branch
   3. Cherry-pick the required non-breaking changes into the `v0.2.x`

+
+## Extending this section
+
+If your PR makes notable changes to Winit's features, please update this section as follows:
+
+- If your PR adds a new feature, add a brief description to the relevant section. If the feature is a core
+  feature, add a row to the feature matrix and describe what platforms the feature has been implemented on.
+
+- If your PR begins a new API rework, add a row to the `Pending API Reworks` table. If the PR implements the
+  API rework on all relevant platforms, please move it to the `Completed API Reworks` table.
+
+- If your PR implements an already-existing feature on a new platform, either mark the feature as *completed*,
+  or mark it as *mostly completed* and link to an issue describing the problems with the implementation.
+
+## Core
+
+### Windowing
+- **Window initialization**: Winit allows the creation of a window
+- **Providing pointer to init OpenGL**: Winit provides the necessary pointers to initialize a working opengl context
+- **Providing pointer to init Vulkan**: Same as OpenGL but for Vulkan
+- **Window decorations**: The windows created by winit are properly decorated, and the decorations can
+  be deactivated
+- **Window decorations toggle**: Decorations can be turned on or off after window creation
+- **Window resizing**: The windows created by winit can be resized and generate the appropriate events
+  when they are. The application can precisely control its window size if desired.
+- **Window resize increments**: When the window gets resized, the application can choose to snap the window's
+  size to specific values.
+- **Window transparency**: Winit allows the creation of windows with a transparent background.
+- **Window maximization**: The windows created by winit can be maximized upon creation.
+- **Window maximization toggle**: The windows created by winit can be maximized and unmaximized after
+  creation.
+- **Window minimization**: The windows created by winit can be minimized after creation.
+- **Fullscreen**: The windows created by winit can be put into fullscreen mode.
+- **Fullscreen toggle**: The windows created by winit can be switched to and from fullscreen after
+  creation.
+- **Exclusive fullscreen**: Winit allows changing the video mode of the monitor
+  for fullscreen windows, and if applicable, captures the monitor for exclusive
+  use by this application.
+- **HiDPI support**: Winit assists developers in appropriately scaling HiDPI content.
+- **Popup / modal windows**: Windows can be created relative to the client area of other windows, and parent
+  windows can be disabled in favor of popup windows. This feature also guarantees that popup windows
+  get drawn above their owner.
+
+
+### System Information
+- **Monitor list**: Retrieve the list of monitors and their metadata, including which one is primary.
+- **Video mode query**: Monitors can be queried for their supported fullscreen video modes (consisting of resolution, refresh rate, and bit depth).
+
+### Input Handling
+- **Mouse events**: Generating mouse events associated with pointer motion, click, and scrolling events.
+- **Mouse set location**: Forcibly changing the location of the pointer.
+- **Cursor locking**: Locking the cursor inside the window so it cannot move.
+- **Cursor confining**: Confining the cursor to the window bounds so it cannot leave them.
+- **Cursor icon**: Changing the cursor icon, or hiding the cursor.
+- **Cursor hittest**: Handle or ignore mouse events for a window.
+- **Touch events**: Single-touch events.
+- **Touch pressure**: Touch events contain information about the amount of force being applied.
+- **Multitouch**: Multi-touch events, including cancellation of a gesture.
+- **Keyboard events**: Properly processing keyboard events using the user-specified keymap and
+  translating keypresses into UTF-8 characters, handling dead keys and IMEs.
+- **Drag & Drop**: Dragging content into winit, detecting when content enters, drops, or if the drop is cancelled.
+- **Raw Device Events**: Capturing input from input devices without any OS filtering.
+- **Gamepad/Joystick events**: Capturing input from gamepads and joysticks.
+- **Device movement events**: Capturing input from the device gyroscope and accelerometer.

 ## Usage
 
 Winit is a window creation and management library. It can create windows and lets you handle
 events (for example: the window being resized, a key being pressed, a mouse movement, etc.)
-produced by the window.
+produced by window.
 
 Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to
 show something on the window you need to use the platform-specific getters provided by winit, or
 another library.
 
-## CONTRIBUTING
+```rust
+use winit::{
+    event::{Event, WindowEvent},
+    event_loop::{ControlFlow, EventLoop},
+    window::WindowBuilder,
+};
 
-For contributing guidelines see [CONTRIBUTING.md](./CONTRIBUTING.md).
+fn main() {
+    let event_loop = EventLoop::new();
+    let window = WindowBuilder::new().build(&event_loop).unwrap();
 
-## MSRV Policy
+    event_loop.run(move |event, _, control_flow| {
+        *control_flow = ControlFlow::Wait;
 
-This crate's Minimum Supported Rust Version (MSRV) is **1.85**. Changes to
-the MSRV will be accompanied by a minor version bump.
-
-As a **tentative** policy, the upper bound of the MSRV is given by the following
-formula:
-
-```
-min(sid, stable - 3)
+        match event {
+            Event::WindowEvent {
+                event: WindowEvent::CloseRequested,
+                window_id,
+            } if window_id == window.id() => *control_flow = ControlFlow::Exit,
+            _ => (),
+        }
+    });
+}
 ```
 
-Where `sid` is the current version of `rustc` provided by [Debian Sid], and
-`stable` is the latest stable version of Rust. This bound may be broken in case of a major ecosystem shift or a security vulnerability.
+Winit is only officially supported on the latest stable version of the Rust compiler.
 
-[Debian Sid]: https://packages.debian.org/sid/rustc
+### Cargo Features
 
-An exception is made for the Android platform, where a higher Rust version
-must be used for certain Android features. In this case, the MSRV will be
-capped at the latest stable version of Rust minus three. This inconsistency is
-not reflected in Cargo metadata, as it is not powerful enough to expose this
-restriction.
-
-Redox OS is also not covered by this MSRV policy, as it requires a Rust nightly
-toolchain to compile.
-
-All crates in the [`rust-windowing`] organizations have the
-same MSRV policy.
-
-[`rust-windowing`]: https://github.com/rust-windowing
+Winit provides the following features, which can be enabled in your `Cargo.toml` file:
+* `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde).
+* `x11` (enabled by default): On Unix platform, compiles with the X11 backend
+* `wayland` (enabled by default): On Unix platform, compiles with the Wayland backend
+* `mint`: Enables mint (math interoperability standard types) conversions.
 
 ### Platform-specific usage
 
-Check out the [`winit::platform`](https://docs.rs/winit/latest/winit/platform/index.html) module for platform-specific usage.
+#### Wayland
 
-### Repository License
+Note that windows don't appear on Wayland until you draw/present to them.
 
-Note that the license in `LICENSE` doesn't apply in full to the DPI package [./dpi](./dpi).
-Full details can be found in that folder's README.
-<!-- This doesn't apply to users of the Winit crate, but this is also the repository level README -->
+#### WebAssembly
+
+To run the web example: `cargo run-wasm --example web`
+
+Winit supports compiling to the `wasm32-unknown-unknown` target with `web-sys`.
+
+On the web platform, a Winit window is backed by a `<canvas>` element. You can
+either [provide Winit with a `<canvas>` element][web with_canvas], or [let Winit
+create a `<canvas>` element which you can then retrieve][web canvas getter] and
+insert it into the DOM yourself.
+
+For example code using Winit with WebAssembly, check out the [web example]. For
+information on using Rust on WebAssembly, check out the [Rust and WebAssembly
+book].
+
+[web with_canvas]: https://docs.rs/winit/latest/wasm32-unknown-unknown/winit/platform/web/trait.WindowBuilderExtWebSys.html#tymethod.with_canvas

+[web example]: ./examples/web.rs
+[Rust and WebAssembly book]: https://rustwasm.github.io/book/
+
+#### Android
+
+The Android backend builds on (and exposes types from) the [`ndk`](https://docs.rs/ndk/0.7.0/ndk/) crate.
+
+Native Android applications need some form of "glue" crate that is responsible
+for defining the main entry point for your Rust application as well as tracking
+various life-cycle events and synchronizing with the main JVM thread.
+
+Winit uses the [android-activity](https://github.com/rib/android-activity) as a
+glue crate (prior to `0.28` it used
+[ndk-glue](https://github.com/rust-windowing/android-ndk-rs/tree/master/ndk-glue)).
+
+The version of the glue crate that your application depends on _must_ match the
+version that Winit depends on because the glue crate is responsible for your
+application's main entrypoint. If Cargo resolves multiple versions they will
+clash.
+
+`winit` glue compatibility table:
+
+| winit |       ndk-glue               |
+| :---: | :--------------------------: |
+| 0.28  | `android-activity = "0.4"`   |
+| 0.27  | `ndk-glue = "0.7"`           |
+| 0.26  | `ndk-glue = "0.5"`           |
+| 0.25  | `ndk-glue = "0.3"`           |
+| 0.24  | `ndk-glue = "0.2"`           |
+
+The recommended way to avoid a conflict with the glue version is to avoid explicitly
+depending on the `android-activity` crate, and instead consume the API that
+is re-exported by Winit under `winit::platform::android::activity::*`
+
+Running on an Android device needs a dynamic system library, add this to Cargo.toml:
+
+```toml
+[lib]
+name = "main"
+crate-type = ["cdylib"]
+```
+
+All Android applications are based on an `Activity` subclass and the
+`android-activity` crate is designed to support different choices for this base
+class. Your application _must_ specify the base class it needs via a feature flag:
+
+| Base Class       | Feature Flag      |  Notes  |
+| :--------------: | :---------------: | :-----: |
+| `NativeActivity` | `android-native-activity` | Built-in to Android - it is possible to use without compiling any Java or Kotlin code. Java or Kotlin code may be needed to subclass `NativeActivity` to access some platform features. It does not derive from the [`AndroidAppCompat`] base class.|
+| [`GameActivity`] | `android-game-activity`   | Derives from [`AndroidAppCompat`] which is a defacto standard `Activity` base class that helps support a wider range of Android versions. Requires a build system that can compile Java or Kotlin and fetch Android dependencies from a [Maven repository][agdk_jetpack] (or link with an embedded [release][agdk_releases] of [`GameActivity`]) |
+
+[`GameActivity`]: https://developer.android.com/games/agdk/game-activity
+[`GameTextInput`]: https://developer.android.com/games/agdk/add-support-for-text-input
+[`AndroidAppCompat`]: https://developer.android.com/reference/androidx/appcompat/app/AppCompatActivity
+[agdk_jetpack]: https://developer.android.com/jetpack/androidx/releases/games
+[agdk_releases]: https://developer.android.com/games/agdk/download#agdk-libraries
+[Gradle]: https://developer.android.com/studio/build
+
+For example, add this to Cargo.toml:
+```toml
+winit = { version = "0.28", features = [ "android-native-activity" ] }
+
+[target.'cfg(target_os = "android")'.dependencies]
+android_logger = "0.11.0"
+```
+
+And, for example, define an entry point for your library like this:
+```rust
+#[cfg(target_os = "android")]
+use winit::platform::android::activity::AndroidApp;
+
+#[cfg(target_os = "android")]
+#[no_mangle]
+fn android_main(app: AndroidApp) {
+    use winit::platform::android::EventLoopBuilderExtAndroid;
+
+    android_logger::init_once(android_logger::Config::default().with_min_level(log::Level::Trace));
+
+    let event_loop = EventLoopBuilder::with_user_event()
+        .with_android_app(app)
+        .build();
+    _main(event_loop);
+}
+```
+
+For more details, refer to these `android-activity` [example applications](https://github.com/rib/android-activity/tree/main/examples).
+
+##### Converting from `ndk-glue` to `android-activity`
+
+If your application is currently based on `NativeActivity` via the `ndk-glue` crate and building with `cargo apk` then the minimal changes would be:
+1. Remove `ndk-glue` from your `Cargo.toml`
+2. Enable the `"android-native-activity"` feature for Winit: `winit = { version = "0.28", features = [ "android-native-activity" ] }`
+3. Add an `android_main` entrypoint (as above), instead of using the '`[ndk_glue::main]` proc macro from `ndk-macros` (optionally add a dependency on `android_logger` and initialize logging as above).
+4. Pass a clone of the `AndroidApp` that your application receives to Winit when building your event loop (as shown above).
+
+#### MacOS
+
+A lot of functionality expects the application to be ready before you start
+doing anything; this includes creating windows, fetching monitors, drawing,
+and so on, see issues [#2238], [#2051] and [#2087].
+
+If you encounter problems, you should try doing your initialization inside
+`Event::NewEvents(StartCause::Init)`.
+
+#### iOS
+
+Similar to macOS, iOS's main `UIApplicationMain` does some init work that's required
+by all UI related code, see issue [#1705]. You should consider creating your windows
+inside `Event::NewEvents(StartCause::Init)`.

-## License
-
-Most of DPI is licensed under the Apache License, Version 2.0 ([LICENSE](LICENSE)).
-All files except for `src/libm.rs` (and `LICENSE-LIBM-MIT`) are available solely under that license.
-
-For its `no_std` support, DPI uses code from the [libm](https://crates.io/crates/libm) crate.
-This is in the `libm.rs` file, and is licensed solely under the MIT Licence ([LICENSE-LIBM-MIT](LICENSE-LIBM-MIT)).
-That file contains details of all potentially applicable copyright notices.
-This is feature gated to only be included if you disable the `std` feature, otherwise it will not be compiled into your final binary
-(and so these license terms will not apply).
-
-Overall, this means that the license for this crate depends on what features you have enabled.
-If you enable the `std` feature, then DPI uses only code available under the Apache-2.0 license, and so can be used under the terms of that license.
-However, if you disable the `std` feature, then both these licenses must be followed to use the crate as a whole.

+//! UI scaling is important, so read the docs for this module if you don't want to be confused.
+//!
+//! ## Why should I care about UI scaling?
+//!
+//! Modern computer screens don't have a consistent relationship between resolution and size.
+//! 1920x1080 is a common resolution for both desktop and mobile screens, despite mobile screens
+//! normally being less than a quarter the size of their desktop counterparts. What's more, neither
+//! desktop nor mobile screens are consistent resolutions within their own size classes - common
+//! mobile screens range from below 720p to above 1440p, and desktop screens range from 720p to 5K
+//! and beyond.
+//!
+//! Given that, it's a mistake to assume that 2D content will only be displayed on screens with
+//! a consistent pixel density. If you were to render a 96-pixel-square image on a 1080p screen,
+//! then render the same image on a similarly-sized 4K screen, the 4K rendition would only take up
+//! about a quarter of the physical space as it did on the 1080p screen. That issue is especially
+//! problematic with text rendering, where quarter-sized text becomes a significant legibility
+//! problem.
+//!
+//! Failure to account for the scale factor can create a significantly degraded user experience.
+//! Most notably, it can make users feel like they have bad eyesight, which will potentially cause
+//! them to think about growing elderly, resulting in them having an existential crisis. Once users
+//! enter that state, they will no longer be focused on your application.
+//!
+//! ## How should I handle it?
+//!
+//! The solution to this problem is to account for the device's *scale factor*. The scale factor is
+//! the factor UI elements should be scaled by to be consistent with the rest of the user's system -
+//! for example, a button that's normally 50 pixels across would be 100 pixels across on a device
+//! with a scale factor of `2.0`, or 75 pixels across with a scale factor of `1.5`.
+//!
+//! Many UI systems, such as CSS, expose DPI-dependent units like [points] or [picas]. That's
+//! usually a mistake, since there's no consistent mapping between the scale factor and the screen's
+//! actual DPI. Unless you're printing to a physical medium, you should work in scaled pixels rather
+//! than any DPI-dependent units.
+//!
+//! ### Position and Size types
+//!
+//! Winit's [`PhysicalPosition`] / [`PhysicalSize`] types correspond with the actual pixels on the
+//! device, and the [`LogicalPosition`] / [`LogicalSize`] types correspond to the physical pixels
+//! divided by the scale factor.
+//! All of Winit's functions return physical types, but can take either logical or physical
+//! coordinates as input, allowing you to use the most convenient coordinate system for your
+//! particular application.
+//!
+//! Winit's position and size types types are generic over their exact pixel type, `P`, to allow the
+//! API to have integer precision where appropriate (e.g. most window manipulation functions) and
+//! floating precision when necessary (e.g. logical sizes for fractional scale factors and touch
+//! input). If `P` is a floating-point type, please do not cast the values with `as {int}`. Doing so
+//! will truncate the fractional part of the float, rather than properly round to the nearest
+//! integer. Use the provided `cast` function or [`From`]/[`Into`] conversions, which handle the
+//! rounding properly. Note that precision loss will still occur when rounding from a float to an
+//! int, although rounding lessens the problem.
+//!
+//! ### Events
+//!
+//! Winit will dispatch a [`ScaleFactorChanged`] event whenever a window's scale factor has changed.
+//! This can happen if the user drags their window from a standard-resolution monitor to a high-DPI
+//! monitor, or if the user changes their DPI settings. This gives you a chance to rescale your
+//! application's UI elements and adjust how the platform changes the window's size to reflect the new
+//! scale factor. If a window hasn't received a [`ScaleFactorChanged`] event,  then its scale factor
+//! can be found by calling [`window.scale_factor()`].
+//!
+//! ## How is the scale factor calculated?
+//!
+//! Scale factor is calculated differently on different platforms:
+//!
+//! - **Windows:** On Windows 8 and 10, per-monitor scaling is readily configured by users from the
+//!   display settings. While users are free to select any option they want, they're only given a
+//!   selection of "nice" scale factors, i.e. 1.0, 1.25, 1.5... on Windows 7, the scale factor is
+//!   global and changing it requires logging out. See [this article][windows_1] for technical
+//!   details.
+//! - **macOS:** Recent versions of macOS allow the user to change the scaling factor for certain
+//!   displays. When this is available, the user may pick a per-monitor scaling factor from a set
+//!   of pre-defined settings. All "retina displays" have a scaling factor above 1.0 by default but
+//!   the specific value varies across devices.
+//! - **X11:** Many man-hours have been spent trying to figure out how to handle DPI in X11. Winit
+//!   currently uses a three-pronged approach:
+//!   + Use the value in the `WINIT_X11_SCALE_FACTOR` environment variable, if present.
+//!   + If not present, use the value set in `Xft.dpi` in Xresources.
+//!   + Otherwise, calculate the scale factor based on the millimeter monitor dimensions provided by XRandR.
+//!
+//!   If `WINIT_X11_SCALE_FACTOR` is set to `randr`, it'll ignore the `Xft.dpi` field and use the
+//!   XRandR scaling method. Generally speaking, you should try to configure the standard system
+//!   variables to do what you want before resorting to `WINIT_X11_SCALE_FACTOR`.
+//! - **Wayland:** On Wayland, scale factors are set per-screen by the server, and are always
+//!   integers (most often 1 or 2).
+//! - **iOS:** Scale factors are set by Apple to the value that best suits the device, and range
+//!   from `1.0` to `3.0`. See [this article][apple_1] and [this article][apple_2] for more
+//!   information.
+//! - **Android:** Scale factors are set by the manufacturer to the value that best suits the
+//!   device, and range from `1.0` to `4.0`. See [this article][android_1] for more information.
+//! - **Web:** The scale factor is the ratio between CSS pixels and the physical device pixels.
+//!   In other words, it is the value of [`window.devicePixelRatio`][web_1]. It is affected by
+//!   both the screen scaling and the browser zoom level and can go below `1.0`.

+//! Winit is a cross-platform window creation and event loop management library.
+//!
+//! # Building windows
+//!
+//! Before you can build a [`Window`], you first need to build an [`EventLoop`]. This is done with the
+//! [`EventLoop::new()`] function.
+//!
+//! ```no_run
+//! use winit::event_loop::EventLoop;
+//! let event_loop = EventLoop::new();
+//! ```
+//!
+//! Once this is done there are two ways to create a [`Window`]:
+//!
+//!  - Calling [`Window::new(&event_loop)`][window_new].
+//!  - Calling [`let builder = WindowBuilder::new()`][window_builder_new] then [`builder.build(&event_loop)`][window_builder_build].
+//!
+//! The first method is the simplest, and will give you default values for everything. The second
+//! method allows you to customize the way your [`Window`] will look and behave by modifying the
+//! fields of the [`WindowBuilder`] object before you create the [`Window`].
+//!
+//! # Event handling
+//!
+//! Once a [`Window`] has been created, it will generate different *events*. A [`Window`] object can
+//! generate [`WindowEvent`]s when certain input events occur, such as a cursor moving over the
+//! window or a key getting pressed while the window is focused. Devices can generate
+//! [`DeviceEvent`]s, which contain unfiltered event data that isn't specific to a certain window.
+//! Some user activity, like mouse movement, can generate both a [`WindowEvent`] *and* a
+//! [`DeviceEvent`]. You can also create and handle your own custom [`UserEvent`]s, if desired.
+//!
+//! You can retrieve events by calling [`EventLoop::run`][event_loop_run]. This function will
+//! dispatch events for every [`Window`] that was created with that particular [`EventLoop`], and
+//! will run until the `control_flow` argument given to the closure is set to
+//! [`ControlFlow`]`::`[`ExitWithCode`] (which [`ControlFlow`]`::`[`Exit`] aliases to), at which
+//! point [`Event`]`::`[`LoopDestroyed`] is emitted and the entire program terminates.
+//!
+//! Winit no longer uses a `EventLoop::poll_events() -> impl Iterator<Event>`-based event loop
+//! model, since that can't be implemented properly on some platforms (e.g web, iOS) and works poorly on
+//! most other platforms. However, this model can be re-implemented to an extent with
+//! [`EventLoopExtRunReturn::run_return`]. See that method's documentation for more reasons about why
+//! it's discouraged, beyond compatibility reasons.
+//!
+//!
+//! ```no_run
+//! use winit::{
+//!     event::{Event, WindowEvent},
+//!     event_loop::EventLoop,
+//!     window::WindowBuilder,
+//! };
+//!
+//! let event_loop = EventLoop::new();
+//! let window = WindowBuilder::new().build(&event_loop).unwrap();
+//!
+//! event_loop.run(move |event, _, control_flow| {
+//!     // ControlFlow::Poll continuously runs the event loop, even if the OS hasn't
+//!     // dispatched any events. This is ideal for games and similar applications.
+//!     control_flow.set_poll();
+//!
+//!     // ControlFlow::Wait pauses the event loop if no events are available to process.
+//!     // This is ideal for non-game applications that only update in response to user
+//!     // input, and uses significantly less power/CPU time than ControlFlow::Poll.
+//!     control_flow.set_wait();
+//!
+//!     match event {
+//!         Event::WindowEvent {
+//!             event: WindowEvent::CloseRequested,
+//!             ..
+//!         } => {
+//!             println!("The close button was pressed; stopping");
+//!             control_flow.set_exit();
+//!         },
+//!         Event::MainEventsCleared => {
+//!             // Application update code.
+//!
+//!             // Queue a RedrawRequested event.
+//!             //
+//!             // You only need to call this if you've determined that you need to redraw, in
+//!             // applications which do not always need to. Applications that redraw continuously
+//!             // can just render here instead.
+//!             window.request_redraw();
+//!         },
+//!         Event::RedrawRequested(_) => {
+//!             // Redraw the application.
+//!             //
+//!             // It's preferable for applications that do not render continuously to render in
+//!             // this event rather than in MainEventsCleared, since rendering in here allows
+//!             // the program to gracefully handle redraws requested by the OS.
+//!         },
+//!         _ => ()
+//!     }
+//! });
+//! ```
+//!
+//! [`Event`]`::`[`WindowEvent`] has a [`WindowId`] member. In multi-window environments, it should be
+//! compared to the value returned by [`Window::id()`][window_id_fn] to determine which [`Window`]
+//! dispatched the event.
+//!
+//! # Drawing on the window
+//!
+//! Winit doesn't directly provide any methods for drawing on a [`Window`]. However it allows you to
+//! retrieve the raw handle of the window and display (see the [`platform`] module and/or the
+//! [`raw_window_handle`] and [`raw_display_handle`] methods), which in turn allows
+//!  you to create an OpenGL/Vulkan/DirectX/Metal/etc. context that can be used to render graphics.
+//!
+//! Note that many platforms will display garbage data in the window's client area if the
+//! application doesn't render anything to the window by the time the desktop compositor is ready to
+//! display the window to the user. If you notice this happening, you should create the window with
+//! [`visible` set to `false`](crate::window::WindowBuilder::with_visible) and explicitly make the
+//! window visible only once you're ready to render into it.
