+# Winit Contributing Guidelines
+
+## 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.
+
+
+## Reporting 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:
+
+- if it is a bug, please provide a 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
+
+## Making a pull request
+
+When making a code contribution to winit, before opening your pull request, please make sure that:
+
+- your patch builds with Winit's minimal supported rust version - Rust 1.70.
+- 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.
+
+  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.
+
+Once your PR is open, you can ask for a 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).
+
+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.
+
+## Maintainers
+
+The current maintainers for each platform are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
+
+## Release process
+
+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`
+  2. A new `v0.2.x` branch is created for the release
+  3. In the branch, the version is bumped to `v0.2.0`
+  4. The new commit in the branch is tagged `v0.2.0`
+  5. The version is pushed to crates.io
+  6. A GitHub release is created for the `v0.2.0` tag
+  7. On master, the version is bumped to `0.2.0`, and the CHANGELOG is updated
+
+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`
+  4. Follow steps 3-7 of the regular release example

+# Winit Scope
+
+Winit aims to expose an interface that abstracts over window creation and input handling and can
+be used to create both games and applications. It supports the following main graphical platforms:
+- Desktop
+  - Windows
+  - macOS
+  - Unix
+    - via X11
+    - via Wayland
+  - Redox OS, via Orbital
+- Mobile
+  - iOS
+  - Android
+- Web
+
+Most platforms expose capabilities that cannot be meaningfully transposed onto others. Winit does not
+aim to support every single feature of every platform, but rather to abstract over the common features
+available everywhere. In this context, APIs exposed in winit can be split into different "support tiers":
+
+- **Core:** Features that are essential to providing a well-formed abstraction over each platform's
+  windowing and input APIs.
+- **Platform:** Platform-specific features that can't be meaningfully exposed through a common API and
+  cannot be implemented outside of Winit without exposing a significant amount of Winit's internals
+  or interfering with Winit's abstractions.
+- **Usability:** Features that are not strictly essential to Winit's functionality, but provide meaningful
+  usability improvements and cannot be reasonably implemented in an external crate. These are
+  generally optional and exposed through Cargo features.
+
+Core features are taken care of by the core Winit maintainers. Platform features are not.
+When a platform feature is submitted, the submitter is considered the expert in the
+feature and may be asked to support the feature should it break in the future.
+
+Winit ***does not*** directly expose functionality for drawing inside windows or creating native
+menus, but ***does*** commit to providing APIs that higher-level crates can use to implement that
+functionality.
+
+## `1.0` and stability
+
+When all core features are implemented to the satisfaction of the Winit maintainers, Winit 1.0 will
+be released and the library will enter maintenance mode. For the most part, new core features will not
+be added past this point. New platform features may be accepted and exposed through point releases.
+
+### Tier upgrades
+Some platform features could, in theory, be exposed across multiple platforms, but have not gone
+through the implementation work necessary to function on all platforms. When one of these features
+gets implemented across all platforms, a PR can be opened to upgrade the feature to a core feature.
+If that gets accepted, the platform-specific functions get deprecated and become permanently
+exposed through the core, cross-platform API.
+
+# Features
+
+## 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 image**: Changing the cursor to your own image.
+- **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.

+# Hall of Champions
+
+The winit maintainers would like to recognize the following former winit
+contributors, without whom winit would not exist in its current form. We thank
+them deeply for their time and efforts and wish them the best of luck in their
+future endeavors:
+
+* [@tomaka]: For creating the winit project and guiding it through its early
+  years of existence.
+* [@vberger]: For diligently creating the Wayland backend and being its
+  extremely helpful and benevolent maintainer for years.
+* [@francesca64]: For taking over the responsibility of maintaining almost every
+  winit backend and standardizing HiDPI support across all of them.
+* [@Osspial]: For heroically landing EventLoop 2.0 and valiantly ushering in a
+  vastly more sustainable era of winit.
+* [@goddessfreya]: For selflessly taking over maintainership of glutin and her
+  stellar dedication to improving both winit and glutin.
+* [@ArturKovacs]: For consistently maintaining the macOS backend and for his immense involvement in designing and implementing the new keyboard API.

 ## 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 mouvement, etc.)
-produced by window.
+events (for example: the window being resized, a key being pressed, a mouse movement, etc.)
+produced by the 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.
 
-```rust
-extern crate winit;
+## MSRV Policy
 
-fn main() {
-    let window = winit::Window::new().unwrap();
+This crate's Minimum Supported Rust Version (MSRV) is **1.70**. 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:
 
-    for event in window.wait_events() {
-        match event {
-            winit::Event::Closed => break,
-            _ => ()
-        }
-    }
-}
 ```
+min(sid, stable - 3)
+```
+
+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.
+
+[Debian Sid]: https://packages.debian.org/sid/rustc
+
+The exception is 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.
+
+All crates in the [`rust-windowing`] organizations have the
+same MSRV policy.
+
+[`rust-windowing`]: https://github.com/rust-windowing

-//! Winit allows you to build a window on as many platforms as possible. 
+//! Winit is a cross-platform window creation and event loop management library.
 //!
-//! # Building a window
+//! # Building windows
 //!
-//! Before you can build a window, you first need to build an `EventsLoop`. This is done with the
-//! `EventsLoop::new()` function. Example:
+//! Before you can create a [`Window`], you first need to build an [`EventLoop`]. This is done with
+//! the [`EventLoop::new()`] function.
 //!
 //! ```no_run
-//! use winit::EventsLoop;
-//! let events_loop = EventsLoop::new();
+//! use winit::event_loop::EventLoop;
+//! let event_loop = EventLoop::new().unwrap();
 //! ```
 //!
-//! Once this is done there are two ways to create a window:
+//! Then you create a [`Window`] with [`create_window`].
 //!
-//!  - Calling `Window::new(&events_loop)`.
-//!  - Calling `let builder = WindowBuilder::new()` then `builder.build(&events_loop)`.
+//! # Event handling
 //!
-//! The first way is the simpliest way and will give you default values for everything.
+//! 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 [`Event::UserEvent`]s, if desired.
 //!
-//! The second way 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.
+//! You can retrieve events by calling [`EventLoop::run_app()`]. This function will
+//! dispatch events for every [`Window`] that was created with that particular [`EventLoop`], and
+//! will run until [`exit()`] is used, at which point [`Event::LoopExiting`].
 //!
-//! # Events handling
+//! 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
+#![cfg_attr(
+    any(
+        windows_platform,

 //!
-//! Once a window has been created, it will *generate events*. For example whenever the user moves
-//! the window, resizes the window, moves the mouse, etc. an event is generated.
-//!
-//! The events generated by a window can be retreived from the `EventsLoop` the window was created
-//! with.
-//!
-//! There are two ways to do so. The first is to call `events_loop.poll_events(...)`, which will
-//! retreive all the events pending on the windows and immediately return after no new event is
-//! available. You usually want to use this method in application that render continuously on the
-//! screen, such as video games.
 //!
 //! ```no_run
-//! use winit::Event;
-//! use winit::WindowEvent;
-//! # use winit::EventsLoop;
-//! # let events_loop = EventsLoop::new();
+//! use winit::application::ApplicationHandler;
+//! use winit::event::WindowEvent;
+//! use winit::event_loop::{ActiveEventLoop, ControlFlow, EventLoop};
+//! use winit::window::{Window, WindowId};
 //!
-//! loop {
-//!     events_loop.poll_events(|event| {
-//!         match event {
-//!             Event::WindowEvent { event: WindowEvent::Resized(w, h), .. } => {
-//!                 println!("The window was resized to {}x{}", w, h);
-//!             },
-//!             _ => ()
-//!         }
-//!     });
+//! #[derive(Default)]
+//! struct App {
+//!     window: Option<Window>,
 //! }
-//! ```
 //!
-//! The second way is to call `events_loop.run_forever(...)`. As its name tells, it will run
-//! forever unless it is stopped by calling `events_loop.interrupt()`.
-//!
-//! ```no_run
-//! use winit::Event;
-//! use winit::WindowEvent;

+//!                 event_loop.exit();

+//!                 // Redraw the application.
+//!                 //
+//!                 // It's preferable for applications that do not render continuously to render in
+//!                 // this event rather than in AboutToWait, since rendering in here allows
+//!                 // the program to gracefully handle redraws requested by the OS.

+//!                 // can render here instead.
+//!                 self.window.as_ref().unwrap().request_redraw();
+//!             }
+//!             _ => (),
+//!         }
+//!     }
+//! }
+//!
+//! let event_loop = EventLoop::new().unwrap();
+//!
+//! // ControlFlow::Poll continuously runs the event loop, even if the OS hasn't
+//! // dispatched any events. This is ideal for games and similar applications.
+//! event_loop.set_control_flow(ControlFlow::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.
+//! event_loop.set_control_flow(ControlFlow::Wait);
+//!
+//! let mut app = App::default();
+//! event_loop.run_app(&mut app);
 //! ```
 //!
-//! If you use multiple windows, the `WindowEvent` event has a member named `window_id`. You can
-//! compare it with the value returned by the `id()` method of `Window` in order to know which
-//! window has received the event.
+//! [`WindowEvent`] has a [`WindowId`] member. In multi-window environments, it should be
+//! compared to the value returned by [`Window::id()`] to determine which [`Window`]
+//! dispatched the event.
 //!
 //! # Drawing on the window
 //!
-//! Winit doesn't provide any function that allows drawing on a window. However it allows you to
-//! retreive the raw handle of the window (see the `os` module for that), which in turn allows you
-//! to create an OpenGL/Vulkan/DirectX/Metal/etc. context that will draw 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::WindowAttributes::with_visible) and explicitly make the
+//! window visible only once you're ready to render into it.
+//!
+//! # UI scaling
+//!
+//! UI scaling is important, go read the docs for the [`dpi`] crate for an
+//! introduction.
+//!
+//! 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 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 allows you 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, its scale factor
+//! can be found by calling [`window.scale_factor()`].
+//!
+//! [`ScaleFactorChanged`]: event::WindowEvent::ScaleFactorChanged
+//! [`window.scale_factor()`]: window::Window::scale_factor
+//!
+//! # Cargo Features
+//!
+//! Winit provides the following Cargo features:
+//!
+//! * `x11` (enabled by default): On Unix platforms, enables the X11 backend.
+//! * `wayland` (enabled by default): On Unix platforms, enables the Wayland
+//!   backend.
+//! * `rwh_04`: Implement `raw-window-handle v0.4` traits.

+//!
+//! All Android applications are based on an `Activity` subclass, and the

+//! | 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`], 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`]) |
+//!

+//!
+//! ## 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 = "0.29.14", 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).

+//! # iOS / UIKit
+//!
+//! Winit has an OS requirement of iOS 8 or higher, and is regularly tested on
+//! iOS 9.3.
+//!
+//! iOS's main `UIApplicationMain` does some init work that's required by all
+//! UI-related code (see issue [#1705]). It is best to create your windows
+//! inside `Event::Resumed`.
+//!
+//! [#1705]: https://github.com/rust-windowing/winit/issues/1705
+//!
+//! ## Building app
+//!
+//! To build ios app you will need rustc built for this targets:
+//!
+//!  - armv7-apple-ios
+//!  - armv7s-apple-ios
+//!  - i386-apple-ios
+//!  - aarch64-apple-ios
+//!  - x86_64-apple-ios
+//!
+//! Then
+//!
+//! ```
+//! cargo build --target=...
+//! ```
+//! The simplest way to integrate your app into xcode environment is to build it
+//! as a static library. Wrap your main function and export it.
+//!
+//! ```rust, ignore
+//! #[no_mangle]
+//! pub extern fn start_winit_app() {
+//!     start_inner()
+//! }
+//!
+//! fn start_inner() {
+//!    ...
+//! }
+//! ```
+//!
+//! Compile project and then drag resulting .a into Xcode project. Add winit.h to xcode.
+//!
+//! ```ignore
+//! void start_winit_app();
+//! ```
+//!
+//! Use start_winit_app inside your xcode's main function.
+//!
+//!
+//! ## App lifecycle and events
+//!
+//! iOS environment is very different from other platforms and you must be very
+//! careful with it's events. Familiarize yourself with
+//! [app lifecycle](https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/).
+//!
+//! This is how those event are represented in winit:
+//!
+//!  - applicationDidBecomeActive is Resumed
+//!  - applicationWillResignActive is Suspended
+//!  - applicationWillTerminate is LoopExiting

-//! iOS support
-//!
-//! # Building app
-//! To build ios app you will need rustc built for this targets:
-//!
-//!  - armv7-apple-ios
-//!  - armv7s-apple-ios
-//!  - i386-apple-ios
-//!  - aarch64-apple-ios
-//!  - x86_64-apple-ios
-//!
-//! Then
-//!
-//! ```
-//! cargo build --target=...
-//! ```
-//! The simplest way to integrate your app into xcode environment is to build it
-//! as a static library. Wrap your main function and export it.
-//!
-//! ```rust, ignore
-//! #[no_mangle]
-//! pub extern fn start_glutin_app() {
-//!     start_inner()
-//! }
-//!
-//! fn start_inner() {
-//!    ...
-//! }
-//!
-//! ```
-//!
-//! Compile project and then drag resulting .a into Xcode project. Add glutin.h to xcode.
-//!
-//! ```ignore
-//! void start_glutin_app();
-//! ```
-//!
-//! Use start_glutin_app inside your xcode's main function.
-//!
-//!
-//! # App lifecycle and events
-//!
-//! iOS environment is very different from other platforms and you must be very
-//! careful with it's events. Familiarize yourself with
-//! [app lifecycle](https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/).
-//!
-//!
-//! This is how those event are represented in glutin:
-//!
-//!  - applicationDidBecomeActive is Focused(true)
-//!  - applicationWillResignActive is Focused(false)
-//!  - applicationDidEnterBackground is Suspended(true)
-//!  - applicationWillEnterForeground is Suspended(false)
-//!  - applicationWillTerminate is Closed
-//!
-//! Keep in mind that after Closed event is received every attempt to draw with
-//! opengl will result in segfault.
-//!
-//! Also note that app will not receive Closed event if suspended, it will be SIGKILL'ed

+//! drawing, and so on, see issues [#2238], [#2051] and [#2087].
+//!
+//! If you encounter problems, you should try doing your initialization inside

+    /// the `drawRect` callback returns.
+    ///
+    ///     For portability it's strongly recommended that applications should
+    /// keep their rendering inside the closure provided to Winit.
+    /// - Any lifecycle events, such as `Suspended` / `Resumed`.
+    ///
+    ///     The handling of these events needs to be synchronized with the
+    /// operating system and it would never be appropriate to buffer a
