@@ -47,202 +47,3 @@ through the implementation work necessary to function on all platforms. When one
 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.

+## 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.

 //!
 //! * `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde).
 //! * `mint`: Enables mint (math interoperability standard types) conversions.
+//! * `std` (enabled by default): Uses the standard library mathematical functions (normally through
+//!   your target platform's libm). This feature also changes the library's license from `Apache-2.0
+//!   AND MIT` to `APACHE-2.0` (only). For full details, see the package README.

-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
-
-The sections should follow the order `Added`, `Changed`, `Deprecated`,
-`Removed`, and `Fixed`.
-
-Platform specific changed should be added to the end of the section and grouped
-by platform name. Common API additions should have `, implemented` at the end
-for platforms where the API was initially implemented. See the following example
-on how to add them:
-
-```md
-### Added
-
-- Add `Window::turbo()`, implemented on X11, Wayland, and Web.
-- On X11, add `Window::some_rare_api`.
-- On X11, add `Window::even_more_rare_api`.
-- On Wayland, add `Window::common_api`.
-- On Windows, add `Window::some_rare_api`.
-```
-
-When the change requires non-trivial amount of work for users to comply
-with it, the migration guide should be added below the entry, like:
-
-```md
-- Deprecate `Window` creation outside of `EventLoop::run`
-
-  This was done to simply migration in the future. Consider the
-  following code:
-
-  // Code snippet.
-
-  To migrate it we should do X, Y, and then Z, for example:
-
-  // Code snippet.
-
-```
-
-The migration guide could reference other migration examples in the current
-changelog entry.

-//! Winit is a cross-platform window creation and event loop management library.
-//!
-//! # Building windows
-//!
-//! 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::event_loop::EventLoop;
-//!
-//! # // Intentionally use `fn main` for clarity
-//! fn main() {
-//!     let event_loop = EventLoop::new().unwrap();
-//!     // ...
-//! }
-//! ```
-//!
-//! Then you create a [`Window`] with [`create_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 [`Event::UserEvent`]s, if
-//! desired.
-//!
-//! 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`].
-//!
-//! 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

-//! ```
-//!
-//! [`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 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.
-//! * `rwh_05`: Implement `raw-window-handle v0.5` traits.
-//! * `rwh_06`: Implement `raw-window-handle v0.6` traits.
-//! * `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde).

-// Brief introduction to the internals of the web backend:
-// The web backend used to support both wasm-bindgen and stdweb as methods of binding to the
-// environment. Because they are both supporting the same underlying APIs, the actual web bindings
-// are cordoned off into backend abstractions, which present the thinnest unifying layer possible.
-//
-// When adding support for new events or interactions with the browser, first consult trusted
-// documentation (such as MDN) to ensure it is well-standardised and supported across many browsers.
-// Once you have decided on the relevant web APIs, add support to both backends.
-//
-// The backend is used by the rest of the module to implement Winit's business logic, which forms
-// the rest of the code. 'device', 'error', 'monitor', and 'window' define web-specific structures
-// for winit's cross-platform structures. They are all relatively simple translations.
-//
-// The event_loop module handles listening for and processing events. 'Proxy' implements
-// EventLoopProxy and 'WindowTarget' implements ActiveEventLoop. WindowTarget also handles
-// registering the event handlers. The 'Execution' struct in the 'runner' module handles taking
-// incoming events (from the registered handlers) and ensuring they are passed to the user in a
-// compliant way.
-
-// TODO: FP, remove when <https://github.com/rust-lang/rust-clippy/issues/12377> is fixed.
