-- On X11, fix `ModifiersChanged` emitting incorrect modifier change events
+[`changelog::unreleased`]: winit/src/changelog/unreleased.md
-- **Breaking**: Overhaul how Winit handles DPI:
+[docs_rs]: https://docs.rs/winit/latest/winit/changelog/index.html
-  + Window functions and events now return `PhysicalSize` instead of `LogicalSize`.
+[master_docs]: https://rust-windowing.github.io/winit/winit/changelog/index.html
-  + Functions that take `Size` or `Position` types can now take either `Logical` or `Physical` types.
-  + `hidpi_factor` has been renamed to `scale_factor`.
-  + `HiDpiFactorChanged` has been renamed to `ScaleFactorChanged`, and lets you control how the OS
-    resizes the window in response to the change.
-  + On X11, deprecate `WINIT_HIDPI_FACTOR` environment variable in favor of `WINIT_X11_SCALE_FACTOR`.
-  + `Size` and `Position` types are now generic over their exact pixel type.

-# 0.20.0 Alpha 6 (2020-01-03)
-
-- On macOS, fix `set_cursor_visible` hides cursor outside of window.
-- On macOS, fix `CursorEntered` and `CursorLeft` events fired at old window size.
-- On macOS, fix error when `set_fullscreen` is called during fullscreen transition.
-- On all platforms except mobile and WASM, implement `Window::set_minimized`.
-- On X11, fix `CursorEntered` event being generated for non-winit windows.
-- On macOS, fix crash when starting maximized without decorations.
-- On macOS, fix application not to terminate on `run_return`.
-- On Wayland, fix cursor icon updates on window borders when using CSD.
-- On Wayland, under mutter(GNOME Wayland), fix CSD being behind the status bar, when starting window in maximized mode.
-- On Windows, theme the title bar according to whether the system theme is "Light" or "Dark".
-- Added `WindowEvent::ThemeChanged` variant to handle changes to the system theme. Currently only implemented on Windows.
-- **Breaking**: Changes to the `RedrawRequested` event (#1041):
-  - `RedrawRequested` has been moved from `WindowEvent` to `Event`.
-  - `EventsCleared` has been renamed to `MainEventsCleared`.
-  - `RedrawRequested` is now issued only after `MainEventsCleared`.
-  - `RedrawEventsCleared` is issued after each set of `RedrawRequested` events.
-- Implement synthetic window focus key events on Windows.
-- **Breaking**: Change `ModifiersState` to a `bitflags` struct.
-- On Windows, implement `VirtualKeyCode` translation for `LWin` and `RWin`.
-- On Windows, fix closing the last opened window causing `DeviceEvent`s to stop getting emitted.
-- On Windows, fix `Window::set_visible` not setting internal flags correctly. This resulted in some weird behavior.
-- Add `DeviceEvent::ModifiersChanged`.
-  - Deprecate `modifiers` fields in other events in favor of `ModifiersChanged`.
-- On X11, `WINIT_HIDPI_FACTOR` now dominates `Xft.dpi` when picking DPI factor for output.
-- On X11, add special value `randr` for `WINIT_HIDPI_FACTOR` to make winit use self computed DPI factor instead of the one from `Xft.dpi`.
-
-# 0.20.0 Alpha 5 (2019-12-09)
-
-- On macOS, fix application termination on `ControlFlow::Exit`
-- On Windows, fix missing `ReceivedCharacter` events when Alt is held.
-- On macOS, stop emitting private corporate characters in `ReceivedCharacter` events.
-- On X11, fix misreporting DPI factor at startup.
-- On X11, fix events not being reported when using `run_return`.
-- On X11, fix key modifiers being incorrectly reported.
-- On X11, fix window creation hanging when another window is fullscreen.
-- On Windows, fix focusing unfocused windows when switching from fullscreen to windowed.
-- On X11, fix reporting incorrect DPI factor when waking from suspend.
-- Change `EventLoopClosed` to contain the original event.
-- **Breaking**: Add `is_synthetic` field to `WindowEvent` variant `KeyboardInput`,
-  indicating that the event is generated by winit.
-- On X11, generate synthetic key events for keys held when a window gains or loses focus.
-- On X11, issue a `CursorMoved` event when a `Touch` event occurs,
-  as X11 implicitly moves the cursor for such events.
-
-# 0.20.0 Alpha 4 (2019-10-18)
-
-- Add web support via the 'stdweb' or 'web-sys' features
-- On Windows, implemented function to get HINSTANCE
-- On macOS, implement `run_return`.
-- On iOS, fix inverted parameter in `set_prefers_home_indicator_hidden`.
-- On X11, performance is improved when rapidly calling `Window::set_cursor_icon`.
-- On iOS, fix improper `msg_send` usage that was UB and/or would break if `!` is stabilized.
-- On Windows, unset `maximized` when manually changing the window's position or size.
-- On Windows, add touch pressure information for touch events.
-- On macOS, differentiate between `CursorIcon::Grab` and `CursorIcon::Grabbing`.
-- On Wayland, fix event processing sometimes stalling when using OpenGL with vsync.
-- Officially remove the Emscripten backend.
-- On Windows, fix handling of surrogate pairs when dispatching `ReceivedCharacter`.
-- On macOS 10.15, fix freeze upon exiting exclusive fullscreen mode.
-- On iOS, fix panic upon closing the app.
-- On X11, allow setting mulitple `XWindowType`s.
-- On iOS, fix null window on initial `HiDpiFactorChanged` event.
-- On Windows, fix fullscreen window shrinking upon getting restored to a normal window.
-- On macOS, fix events not being emitted during modal loops, such as when windows are being resized
-  by the user.
-- On Windows, fix hovering the mouse over the active window creating an endless stream of CursorMoved events.
-- Always dispatch a `RedrawRequested` event after creating a new window.
-- On X11, return dummy monitor data to avoid panicking when no monitors exist.
-- On X11, prevent stealing input focus when creating a new window.

-
-# 0.20.0 Alpha 1 (2019-06-21)
-
-- Changes below are considered **breaking**.
-- Change all occurrences of `EventsLoop` to `EventLoop`.
-- Previously flat API is now exposed through `event`, `event_loop`, `monitor`, and `window` modules.
-- `os` module changes:
-  - Renamed to `platform`.
-  - All traits now have platform-specific suffixes.
-  - Exposes new `desktop` module on Windows, Mac, and Linux.
-- Changes to event loop types:
-  - `EventLoopProxy::wakeup` has been removed in favor of `send_event`.
-  - **Major:** New `run` method drives winit event loop.
-    - Returns `!` to ensure API behaves identically across all supported platforms.
-      - This allows `emscripten` implementation to work without lying about the API.
-    - `ControlFlow`'s variants have been replaced with `Wait`, `WaitUntil(Instant)`, `Poll`, and `Exit`.
-      - Is read after `EventsCleared` is processed.
-      - `Wait` waits until new events are available.
-      - `WaitUntil` waits until either new events are available or the provided time has been reached.
-      - `Poll` instantly resumes the event loop.
-      - `Exit` aborts the event loop.
-    - Takes a closure that implements `'static + FnMut(Event<T>, &EventLoop<T>, &mut ControlFlow)`.
-      - `&EventLoop<T>` is provided to allow new `Window`s to be created.
-  - **Major:** `platform::desktop` module exposes `EventLoopExtDesktop` trait with `run_return` method.
-    - Behaves identically to `run`, but returns control flow to the calling context and can take non-`'static` closures.
-  - `EventLoop`'s `poll_events` and `run_forever` methods have been removed in favor of `run` and `run_return`.
-- Changes to events:
-  - Remove `Event::Awakened` in favor of `Event::UserEvent(T)`.
-    - Can be sent with `EventLoopProxy::send_event`.
-  - Rename `WindowEvent::Refresh` to `WindowEvent::RedrawRequested`.
-    - `RedrawRequested` can be sent by the user with the `Window::request_redraw` method.
-  - `EventLoop`, `EventLoopProxy`, and `Event` are now generic over `T`, for use in `UserEvent`.
-  - **Major:** Add `NewEvents(StartCause)`, `EventsCleared`, and `LoopDestroyed` variants to `Event`.
-    - `NewEvents` is emitted when new events are ready to be processed by event loop.
-      - `StartCause` describes why new events are available, with `ResumeTimeReached`, `Poll`, `WaitCancelled`, and `Init` (sent once at start of loop).
-    - `EventsCleared` is emitted when all available events have been processed.
-      - Can be used to perform logic that depends on all events being processed (e.g. an iteration of a game loop).
-    - `LoopDestroyed` is emitted when the `run` or `run_return` method is about to exit.
-- Rename `MonitorId` to `MonitorHandle`.
-- Removed `serde` implementations from `ControlFlow`.
-- Rename several functions to improve both internal consistency and compliance with Rust API guidelines.
-- Remove `WindowBuilder::multitouch` field, since it was only implemented on a few platforms. Multitouch is always enabled now.
-- **Breaking:** On macOS, change `ns` identifiers to use snake_case for consistency with iOS's `ui` identifiers.
-- Add `MonitorHandle::video_modes` method for retrieving supported video modes for the given monitor.
-- On Wayland, the window now exists even if nothing has been drawn.
-- On Windows, fix initial dimensions of a fullscreen window.
-- On Windows, Fix transparent borderless windows rendering wrong.
-
-# Version 0.19.1 (2019-04-08)
-

-- On Linux, the numpad's add, subtract and divide keys are now mapped to the `Add`, `Subtract` and `Divide` virtual key codes
-- On macOS, the numpad's subtract key has been added to the `Subtract` mapping
-- On Wayland, the numpad's home, end, page up and page down keys are now mapped to the `Home`, `End`, `PageUp` and `PageDown` virtual key codes
-- On Windows, fix icon not showing up in corner of window.
-- On X11, change DPI scaling factor behavior. First, winit tries to read it from "Xft.dpi" XResource, and uses DPI calculation from xrandr dimensions as fallback behavior.
-
-# Version 0.19.0 (2019-03-06)
-
-- On X11, we will use the faster `XRRGetScreenResourcesCurrent` function instead of `XRRGetScreenResources` when available.
-- On macOS, fix keycodes being incorrect when using a non-US keyboard layout.
-- On Wayland, fix `with_title()` not setting the windows title
-- On Wayland, add `set_wayland_theme()` to control client decoration color theme
-- Added serde serialization to `os::unix::XWindowType`.
-- **Breaking:** Remove the `icon_loading` feature and the associated `image` dependency.

-- On Windows, fix malformed function pointer typecast that could invoke undefined behavior.
-- Refactored Windows state/flag-setting code.
-- On Windows, hiding the cursor no longer hides the cursor for all Winit windows - just the one `hide_cursor` was called on.
-- On Windows, cursor grabs used to get perpetually canceled when the grabbing window lost focus. Now, cursor grabs automatically get re-initialized when the window regains focus and the mouse moves over the client area.
-- On Windows, only vertical mouse wheel events were handled. Now, horizontal mouse wheel events are also handled.
-- On Windows, ignore the AltGr key when populating the `ModifersState` type.
-
-# Version 0.18.1 (2018-12-30)
-
-- On macOS, fix `Yen` (JIS) so applications receive the event.
-- On X11 with a tiling WM, fixed high CPU usage when moving windows across monitors.
-- On X11, fixed panic caused by dropping the window before running the event loop.

-- Introduce `WindowBuilderExt::with_app_id` to allow setting the application ID on Wayland.
-- On Windows, catch panics in event loop child thread and forward them to the parent thread. This prevents an invocation of undefined behavior due to unwinding into foreign code.
-- On Windows, fix issue where resizing or moving window combined with grabbing the cursor would freeze program.
-- On Windows, fix issue where resizing or moving window would eat `Awakened` events.
-- On Windows, exiting fullscreen after entering fullscreen with disabled decorations no longer shrinks window.

-- On Wayland, DPI calculation is handled by smithay-client-toolkit.
-- On X11, `WindowBuilder::with_min_dimensions` and `WindowBuilder::with_max_dimensions` now correctly account for DPI.
-- Added support for generating dummy `DeviceId`s and `WindowId`s to better support unit testing.
-- On macOS, fixed unsoundness in drag-and-drop that could result in drops being rejected.
-- On macOS, implemented `WindowEvent::Refresh`.
-- On macOS, all `MouseCursor` variants are now implemented and the cursor will no longer reset after unfocusing.
-- Removed minimum supported Rust version guarantee.
-
-# Version 0.18.0 (2018-11-07)
-
-- **Breaking:** `image` crate upgraded to 0.20. This is exposed as part of the `icon_loading` API.
-- On Wayland, pointer events will now provide the current modifiers state.
-- On Wayland, titles will now be displayed in the window header decoration.
-- On Wayland, key repetition is now ended when keyboard loses focus.

-- Added `WindowBuilderExt::with_gtk_theme_variant` to X11-specific `WindowBuilder` functions.
-- Fixed UTF8 handling bug in X11 `set_title` function.
-- On Windows, `Window::set_cursor` now applies immediately instead of requiring specific events to occur first.
-- On Windows, the `HoveredFile` and `HoveredFileCancelled` events are now implemented.
-- On Windows, fix `Window::set_maximized`.
-- On Windows 10, fix transparency (#260).
-- On macOS, fix modifiers during key repeat.
-- Implemented the `Debug` trait for `Window`, `EventsLoop`, `EventsLoopProxy` and `WindowBuilder`.
-- On X11, now a `Resized` event will always be generated after a DPI change to ensure the window's logical size is consistent with the new DPI.
-- Added further clarifications to the DPI docs.
-- On Linux, if neither X11 nor Wayland manage to initialize, the corresponding panic now consists of a single line only.
-- Add optional `serde` feature with implementations of `Serialize`/`Deserialize` for DPI types and various event types.
-- Add `PartialEq`, `Eq`, and `Hash` implementations on public types that could have them but were missing them.
-- On X11, drag-and-drop receiving an unsupported drop type can no longer cause the WM to freeze.
-- Fix issue whereby the OpenGL context would not appear at startup on macOS Mojave (#1069).
-- **Breaking:** Removed `From<NSApplicationActivationPolicy>` impl from `ActivationPolicy` on macOS.
-- On macOS, the application can request the user's attention with `WindowExt::request_user_attention`.
-
-# Version 0.17.2 (2018-08-19)
-
-- On macOS, fix `<C-Tab>` so applications receive the event.
-- On macOS, fix `<Cmd-{key}>` so applications receive the event.
-- On Wayland, key press events will now be repeated.
-
-# Version 0.17.1 (2018-08-05)
-
-- On X11, prevent a compilation failure in release mode for versions of Rust greater than or equal to 1.30.
-- Fixed deadlock that broke fullscreen mode on Windows.
-
-# Version 0.17.0 (2018-08-02)
-
-- Cocoa and core-graphics updates.
-- Fixed thread-safety issues in several `Window` functions on Windows.
-- On MacOS, the key state for modifiers key events is now properly set.
-- On iOS, the view is now set correctly. This makes it possible to render things (instead of being stuck on a black screen), and touch events work again.
-- Added NetBSD support.
-- **Breaking:** On iOS, `UIView` is now the default root view. `WindowBuilderExt::with_root_view_class` can be used to set the root view objective-c class to `GLKView` (OpenGLES) or `MTKView` (Metal/MoltenVK).
-- On iOS, the `UIApplication` is not started until `Window::new` is called.
-- Fixed thread unsafety with cursor hiding on macOS.
-- On iOS, fixed the size of the `JmpBuf` type used for `setjmp`/`longjmp` calls. Previously this was a buffer overflow on most architectures.
-- On Windows, use cached window DPI instead of repeatedly querying the system. This fixes sporadic crashes on Windows 7.
-
-# Version 0.16.2 (2018-07-07)
-
-- On Windows, non-resizable windows now have the maximization button disabled. This is consistent with behavior on macOS and popular X11 WMs.
-- Corrected incorrect `unreachable!` usage when guessing the DPI factor with no detected monitors.
-
-# Version 0.16.1 (2018-07-02)
-
-- Added logging through `log`. Logging will become more extensive over time.
-- On X11 and Windows, the window's DPI factor is guessed before creating the window. This *greatly* cuts back on unsightly auto-resizing that would occur immediately after window creation.
-- Fixed X11 backend compilation for environments where `c_char` is unsigned.
-
-# Version 0.16.0 (2018-06-25)
-
-- Windows additionally has `WindowBuilderExt::with_no_redirection_bitmap`.
-- **Breaking:** Removed `VirtualKeyCode::LMenu` and `VirtualKeyCode::RMenu`; Windows now generates `VirtualKeyCode::LAlt` and `VirtualKeyCode::RAlt` instead.
-- On X11, exiting fullscreen no longer leaves the window in the monitor's top left corner.
-- **Breaking:** `Window::hidpi_factor` has been renamed to `Window::get_hidpi_factor` for better consistency. `WindowEvent::HiDPIFactorChanged` has been renamed to `WindowEvent::HiDpiFactorChanged`. DPI factors are always represented as `f64` instead of `f32` now.
-- The Windows backend is now DPI aware. `WindowEvent::HiDpiFactorChanged` is implemented, and `MonitorId::get_hidpi_factor` and `Window::hidpi_factor` return accurate values.
-- Implemented `WindowEvent::HiDpiFactorChanged` on X11.
-- On macOS, `Window::set_cursor_position` is now relative to the client area.
-- On macOS, setting the maximum and minimum dimensions now applies to the client area dimensions rather than to the window dimensions.
-- On iOS, `MonitorId::get_dimensions` has been implemented and both `MonitorId::get_hidpi_factor` and `Window::get_hidpi_factor` return accurate values.
-- On Emscripten, `MonitorId::get_hidpi_factor` now returns the same value as `Window::get_hidpi_factor` (it previously would always return 1.0).
-- **Breaking:** The entire API for sizes, positions, etc. has changed. In the majority of cases, winit produces and consumes positions and sizes as `LogicalPosition` and `LogicalSize`, respectively. The notable exception is `MonitorId` methods, which deal in `PhysicalPosition` and `PhysicalSize`. See the documentation for specifics and explanations of the types. Additionally, winit automatically conserves logical size when the DPI factor changes.
-- **Breaking:** All deprecated methods have been removed. For `Window::platform_display` and `Window::platform_window`, switch to the appropriate platform-specific `WindowExt` methods. For `Window::get_inner_size_points` and `Window::get_inner_size_pixels`, use the `LogicalSize` returned by `Window::get_inner_size` and convert as needed.
-- HiDPI support for Wayland.
-- `EventsLoop::get_available_monitors` and `EventsLoop::get_primary_monitor` now have identical counterparts on `Window`, so this information can be acquired without an `EventsLoop` borrow.
-- `AvailableMonitorsIter` now implements `Debug`.
-- Fixed quirk on macOS where certain keys would generate characters at twice the normal rate when held down.
-- On X11, all event loops now share the same `XConnection`.
-- **Breaking:** `Window::set_cursor_state` and `CursorState` enum removed in favor of the more composable `Window::grab_cursor` and `Window::hide_cursor`. As a result, grabbing the cursor no longer automatically hides it; you must call both methods to retain the old behavior on Windows and macOS. `Cursor::NoneCursor` has been removed, as it's no longer useful.
-- **Breaking:** `Window::set_cursor_position` now returns `Result<(), String>`, thus allowing for `Box<Error>` conversion via `?`.
-
-# Version 0.15.1 (2018-06-13)
-
-- On X11, the `Moved` event is no longer sent when the window is resized without changing position.
-- `MouseCursor` and `CursorState` now implement `Default`.
-- `WindowBuilder::with_resizable` implemented for Windows, X11, Wayland, and macOS.
-- `Window::set_resizable` implemented for Windows, X11, Wayland, and macOS.
-- On X11, if the monitor's width or height in millimeters is reported as 0, the DPI is now 1.0 instead of +inf.
-- On X11, the environment variable `WINIT_HIDPI_FACTOR` has been added for overriding DPI factor.
-- On X11, enabling transparency no longer causes the window contents to flicker when resizing.
-- On X11, `with_override_redirect` now actually enables override redirect.
-- macOS now generates `VirtualKeyCode::LAlt` and `VirtualKeyCode::RAlt` instead of `None` for both.
-- On macOS, `VirtualKeyCode::RWin` and `VirtualKeyCode::LWin` are no longer switched.
-- On macOS, windows without decorations can once again be resized.
-- Fixed race conditions when creating an `EventsLoop` on X11, most commonly manifesting as "[xcb] Unknown sequence number while processing queue".
-- On macOS, `CursorMoved` and `MouseInput` events are only generated if they occurs within the window's client area.
-- On macOS, resizing the window no longer generates a spurious `MouseInput` event.
-
-# Version 0.15.0 (2018-05-22)
-
-- `Icon::to_cardinals` is no longer public, since it was never supposed to be.
-- Wayland: improve diagnostics if initialization fails
-- Fix some system event key doesn't work when focused, do not block keyevent forward to system on macOS
-- On X11, the scroll wheel position is now correctly reset on i3 and other WMs that have the same quirk.
-- On X11, `Window::get_current_monitor` now reliably returns the correct monitor.
-- On X11, `Window::hidpi_factor` returns values from XRandR rather than the inaccurate values previously queried from the core protocol.
-- On X11, the primary monitor is detected correctly even when using versions of XRandR less than 1.5.
-- `MonitorId` now implements `Debug`.
-- Fixed bug on macOS where using `with_decorations(false)` would cause `set_decorations(true)` to produce a transparent titlebar with no title.
-- Implemented `MonitorId::get_position` on macOS.
-- On macOS, `Window::get_current_monitor` now returns accurate values.
-- Added `WindowBuilderExt::with_resize_increments` to macOS.
-- **Breaking:** On X11, `WindowBuilderExt::with_resize_increments` and `WindowBuilderExt::with_base_size` now take `u32` values rather than `i32`.
-- macOS keyboard handling has been overhauled, allowing for the use of dead keys, IME, etc. Right modifier keys are also no longer reported as being left.
-- Added the `Window::set_ime_spot(x: i32, y: i32)` method, which is implemented on X11 and macOS.
-- **Breaking**: `os::unix::WindowExt::send_xim_spot(x: i16, y: i16)` no longer exists. Switch to the new `Window::set_ime_spot(x: i32, y: i32)`, which has equivalent functionality.
-- Fixed detection of `Pause` and `Scroll` keys on Windows.
-- On Windows, alt-tabbing while the cursor is grabbed no longer makes it impossible to re-grab the cursor.
-- On Windows, using `CursorState::Hide` when the cursor is grabbed now ungrabs the cursor first.
-- Implemented `MouseCursor::NoneCursor` on Windows.
-- Added `WindowBuilder::with_always_on_top` and `Window::set_always_on_top`. Implemented on Windows, macOS, and X11.
-- On X11, `WindowBuilderExt` now has `with_class`, `with_override_redirect`, and `with_x11_window_type` to allow for more control over window creation. `WindowExt` additionally has `set_urgent`.
-- More hints are set by default on X11, including `_NET_WM_PID` and `WM_CLIENT_MACHINE`. Note that prior to this, the `WM_CLASS` hint was automatically set to whatever value was passed to `with_title`. It's now set to the executable name to better conform to expectations and the specification; if this is undesirable, you must explicitly use `WindowBuilderExt::with_class`.
-
-# Version 0.14.0 (2018-05-09)
-
-- Created the `Copy`, `Paste` and `Cut` `VirtualKeyCode`s and added support for them on X11 and Wayland
-- Fix `.with_decorations(false)` in macOS
-- On Mac, `NSWindow` and supporting objects might be alive long after they were `closed` which resulted in apps consuming more heap then needed. Mainly it was affecting multi window applications. Not expecting any user visible change of behaviour after the fix.
-- Fix regression of Window platform extensions for macOS where `NSFullSizeContentViewWindowMask` was not being correctly applied to `.fullsize_content_view`.
-- Corrected `get_position` on Windows to be relative to the screen rather than to the taskbar.
-- Corrected `Moved` event on Windows to use position values equivalent to those returned by `get_position`. It previously supplied client area positions instead of window positions, and would additionally interpret negative values as being very large (around `u16::MAX`).
-- Implemented `Moved` event on macOS.
-- On X11, the `Moved` event correctly use window positions rather than client area positions. Additionally, a stray `Moved` that unconditionally accompanied `Resized` with the client area position relative to the parent has been eliminated; `Moved` is still received alongside `Resized`, but now only once and always correctly.
-- On Windows, implemented all variants of `DeviceEvent` other than `Text`. Mouse `DeviceEvent`s are now received even if the window isn't in the foreground.
-- `DeviceId` on Windows is no longer a unit struct, and now contains a `u32`. For `WindowEvent`s, this will always be 0, but on `DeviceEvent`s it will be the handle to that device. `DeviceIdExt::get_persistent_identifier` can be used to acquire a unique identifier for that device that persists across replugs/reboots/etc.
-- Corrected `run_forever` on X11 to stop discarding `Awakened` events.
-- Various safety and correctness improvements to the X11 backend internals.
-- Fixed memory leak on X11 every time the mouse entered the window.
-- On X11, drag and drop now works reliably in release mode.
-- Added `WindowBuilderExt::with_resize_increments` and `WindowBuilderExt::with_base_size` to X11, allowing for more optional hints to be set.
-- Rework of the wayland backend, migrating it to use [Smithay's Client Toolkit](https://github.com/Smithay/client-toolkit).
-- Added `WindowBuilder::with_window_icon` and `Window::set_window_icon`, finally making it possible to set the window icon on Windows and X11. The `icon_loading` feature can be enabled to allow for icons to be easily loaded; see example program `window_icon.rs` for usage.
-- Windows additionally has `WindowBuilderExt::with_taskbar_icon` and `WindowExt::set_taskbar_icon`.
-- On Windows, fix panic when trying to call `set_fullscreen(None)` on a window that has not been fullscreened prior.
-
-# Version 0.13.1 (2018-04-26)
-
-- Ensure necessary `x11-dl` version is used.
-
-# Version 0.13.0 (2018-04-25)
-
-- Implement `WindowBuilder::with_maximized`, `Window::set_fullscreen`, `Window::set_maximized` and `Window::set_decorations` for MacOS.
-- Implement `WindowBuilder::with_maximized`, `Window::set_fullscreen`, `Window::set_maximized` and `Window::set_decorations` for Windows.
-- On Windows, `WindowBuilder::with_fullscreen` no longer changing monitor display resolution.
-- Overhauled X11 window geometry calculations. `get_position` and `set_position` are more universally accurate across different window managers, and `get_outer_size` actually works now.
-- Fixed SIGSEGV/SIGILL crashes on macOS caused by stabilization of the `!` (never) type.
-- Implement `WindowEvent::HiDPIFactorChanged` for macOS
-- On X11, input methods now work completely out of the box, no longer requiring application developers to manually call `setlocale`. Additionally, when input methods are started, stopped, or restarted on the server end, it's correctly handled.
-- Implemented `Refresh` event on Windows.
-- Properly calculate the minimum and maximum window size on Windows, including window decorations.
-- Map more `MouseCursor` variants to cursor icons on Windows.
-- Corrected `get_position` on macOS to return outer frame position, not content area position.
-- Corrected `set_position` on macOS to set outer frame position, not content area position.
-- Added `get_inner_position` method to `Window`, which gets the position of the window's client area. This is implemented on all applicable platforms (all desktop platforms other than Wayland, where this isn't possible).
-- **Breaking:** the `Closed` event has been replaced by `CloseRequested` and `Destroyed`. To migrate, you typically just need to replace all usages of `Closed` with `CloseRequested`; see example programs for more info. The exception is iOS, where `Closed` must be replaced by `Destroyed`.
-
-# Version 0.12.0 (2018-04-06)
-
-- Added subclass to macos windows so they can be made resizable even with no decorations.
-- Dead keys now work properly on X11, no longer resulting in a panic.
-- On X11, input method creation first tries to use the value from the user's `XMODIFIERS` environment variable, so application developers should no longer need to manually call `XSetLocaleModifiers`. If that fails, fallbacks are tried, which should prevent input method initialization from ever outright failing.
-- Fixed thread safety issues with input methods on X11.
-- Add support for `Touch` for win32 backend.
-- Fixed `Window::get_inner_size` and friends to return the size in pixels instead of points when using HIDPI displays on OSX.
-
-# Version 0.11.3 (2018-03-28)
-
-- Added `set_min_dimensions` and `set_max_dimensions` methods to `Window`, and implemented on Windows, X11, Wayland, and OSX.
-- On X11, dropping a `Window` actually closes it now, and clicking the window's × button (or otherwise having the WM signal to close it) will result in the window closing.
-- Added `WindowBuilderExt` methods for macos: `with_titlebar_transparent`,
-  `with_title_hidden`, `with_titlebar_buttons_hidden`,
-  `with_fullsize_content_view`.
-- Mapped X11 numpad keycodes (arrows, Home, End, PageUp, PageDown, Insert and Delete) to corresponding virtual keycodes
-
-# Version 0.11.2 (2018-03-06)
-
-- Impl `Hash`, `PartialEq`, and `Eq` for `events::ModifiersState`.
-- Implement `MonitorId::get_hidpi_factor` for MacOS.
-- Added method `os::macos::MonitorIdExt::get_nsscreen() -> *mut c_void` that gets a `NSScreen` object matching the monitor ID.
-- Send `Awakened` event on Android when event loop is woken up.
-
-# Version 0.11.1 (2018-02-19)
-
-- Fixed windows not receiving mouse events when click-dragging the mouse outside the client area of a window, on Windows platforms.
-- Added method `os::android::EventsLoopExt:set_suspend_callback(Option<Box<Fn(bool) -> ()>>)` that allows glutin to register a callback when a suspend event happens
-
-# Version 0.11.0 (2018-02-09)
-
-- Implement `MonitorId::get_dimensions` for Android.
-- Added method `os::macos::WindowBuilderExt::with_movable_by_window_background(bool)` that allows to move a window without a titlebar - `with_decorations(false)`
-- Implement `Window::set_fullscreen`, `Window::set_maximized` and `Window::set_decorations` for Wayland.
-- Added `Caret` as VirtualKeyCode and support OSX ^-Key with german input.
-
-# Version 0.10.1 (2018-02-05)
-
-*Yanked*
-
-# Version 0.10.0 (2017-12-27)
-
-- Add support for `Touch` for emscripten backend.
-- Added support for `DroppedFile`, `HoveredFile`, and `HoveredFileCancelled` to X11 backend.
-- **Breaking:** `unix::WindowExt` no longer returns pointers for things that aren't actually pointers; `get_xlib_window` now returns `Option<std::os::raw::c_ulong>` and `get_xlib_screen_id` returns `Option<std::os::raw::c_int>`. Additionally, methods that previously returned `libc::c_void` have been changed to return `std::os::raw::c_void`, which are not interchangeable types, so users wanting the former will need to explicitly cast.
-- Added `set_decorations` method to `Window` to allow decorations to be toggled after the window is built. Presently only implemented on X11.
-- Raised the minimum supported version of Rust to 1.20 on MacOS due to usage of associated constants in new versions of cocoa and core-graphics.
-- Added `modifiers` field to `MouseInput`, `MouseWheel`, and `CursorMoved` events to track the modifiers state (`ModifiersState`).
-- Fixed the emscripten backend to return the size of the canvas instead of the size of the window.
-
-# Version 0.9.0 (2017-12-01)
-
-- Added event `WindowEvent::HiDPIFactorChanged`.
-- Added method `MonitorId::get_hidpi_factor`.
-- Deprecated `get_inner_size_pixels` and `get_inner_size_points` methods of `Window` in favor of
-`get_inner_size`.
-- **Breaking:** `EventsLoop` is `!Send` and `!Sync` because of platform-dependant constraints,
-  but `Window`, `WindowId`, `DeviceId` and `MonitorId` guaranteed to be `Send`.
-- `MonitorId::get_position` now returns `(i32, i32)` instead of `(u32, u32)`.
-- Rewrite of the wayland backend to use wayland-client-0.11
-- Support for dead keys on wayland for keyboard utf8 input
-- Monitor enumeration on Windows is now implemented using `EnumDisplayMonitors` instead of
-`EnumDisplayDevices`. This changes the value returned by `MonitorId::get_name()`.
-- On Windows added `MonitorIdExt::hmonitor` method
-- Impl `Clone` for `EventsLoopProxy`
-- `EventsLoop::get_primary_monitor()` on X11 will fallback to any available monitor if no primary is found
-- Support for touch event on wayland
-- `WindowEvent`s `MouseMoved`, `MouseEntered`, and `MouseLeft` have been renamed to
-`CursorMoved`, `CursorEntered`, and `CursorLeft`.
-- New `DeviceEvent`s added, `MouseMotion` and `MouseWheel`.
-- Send `CursorMoved` event after `CursorEntered` and `Focused` events.
-- Add support for `ModifiersState`, `MouseMove`, `MouseInput`, `MouseMotion` for emscripten backend.
-
-# Version 0.8.3 (2017-10-11)
-
-- Fixed issue of calls to `set_inner_size` blocking on Windows.
-- Mapped `ISO_Left_Tab` to `VirtualKeyCode::Tab` to make the key work with modifiers
-- Fixed the X11 backed on 32bit targets
-
-# Version 0.8.2 (2017-09-28)
-
-- Uniformize keyboard scancode values accross Wayland and X11 (#297).
-- Internal rework of the wayland event loop
-- Added method `os::linux::WindowExt::is_ready`
-
-# Version 0.8.1 (2017-09-22)
-
-- Added various methods to `os::linux::EventsLoopExt`, plus some hidden items necessary to make
-  glutin work.
-
-# Version 0.8.0 (2017-09-21)
-
-- Added `Window::set_maximized`, `WindowAttributes::maximized` and `WindowBuilder::with_maximized`.
-- Added `Window::set_fullscreen`.
-- Changed `with_fullscreen` to take a `Option<MonitorId>` instead of a `MonitorId`.
-- Removed `MonitorId::get_native_identifer()` in favor of platform-specific traits in the `os`
-  module.
-- Changed `get_available_monitors()` and `get_primary_monitor()` to be methods of `EventsLoop`
-  instead of stand-alone methods.
-- Changed `EventsLoop` to be tied to a specific X11 or Wayland connection.
-- Added a `os::linux::EventsLoopExt` trait that makes it possible to configure the connection.
-- Fixed the emscripten code, which now compiles.
-- Changed the X11 fullscreen code to use `xrandr` instead of `xxf86vm`.
-- Fixed the Wayland backend to produce `Refresh` event after window creation.
-- Changed the `Suspended` event to be outside of `WindowEvent`.
-- Fixed the X11 backend sometimes reporting the wrong virtual key (#273).

-may be worth creating a separate crate that extends Winit's API to add that functionality.
 
+## Contributing
 
-## Reporting an issue
+Anyone can contribute to winit, however given that it's a cross platform

+
+#### Handling review
+
+During the review process certain events could require an action from your side,
+common patterns and reactions are described below.
+
+_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.
+
+_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
+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. 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
+
+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 4-9 of the regular release example

-# 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 grab**: Locking the cursor so it cannot exit the client area of a window.
-- **Cursor icon**: Changing the cursor icon, or hiding the cursor.
-- **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 gampads 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 window.
+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.

-Winit provides the following features, which can be enabled in your `Cargo.toml` file:
+An exception is made for the Android platform, where a higher Rust version

+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

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+Please keep one empty line before and after all headers. (This is required for
+`git` to produce a conflict when a release is made while a PR is open and the
+PR's changelog entry would go into the wrong section).
+
+And please only add new entries to the top of this list, right below the `#
+Unreleased` header.
+
+## Unreleased
+
+## 0.1.2
+
+- Added `Insets`, `LogicalInsets` and `PhysicalInsets` types.
+- Make `no_std` compatible. If you use this functionality, DPI's license has changed.
+
+## 0.1.1
+
+- Derive `Debug`, `Copy`, `Clone`, `PartialEq`, `Serialize`, `Deserialize` traits for `PixelUnit`.
+
+## 0.1.0
+
+- Add `LogicalUnit`, `PhysicalUnit` and `PixelUnit` types and related functions.

+## 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 `Physical(Position|Size)` types correspond with the actual pixels on the device, and the
-//! `Logical(Position|Size)` 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`](crate::event::WindowEvent::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`](crate::event::WindowEvent::ScaleFactorChanged) event,
-//! then its scale factor is `1.0`.
-//!
-//! ## 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:** "retina displays" have a scale factor of 2.0. Otherwise, the scale factor is 1.0.
-//!   Intermediate scale factors are never used. It's possible for any display to use that 2.0 scale
-//!   factor, given the use of the command line.
-//! - **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, calcuate 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.

-//! 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 retreive 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`]`::`[`Exit`], 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 web and mobile platforms and works poorly on
-//! most desktop platforms. However, this model can be re-implemented to an extent on desktops with
-//! [`EventLoopExtDesktop::run_return`]. See that method's documentation for more reasons about why
-//! it's discouraged, beyond mobile/web compatibility reasons.
-//!
-//!
-//! ```no_run
-//! use winit::{
-//!     event::{Event, WindowEvent},
-//!     event_loop::{ControlFlow, 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 = 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.
-//!     *control_flow = ControlFlow::Wait;
-//!
-//!     match event {
-//!         Event::WindowEvent {
-//!             event: WindowEvent::CloseRequested,
-//!             ..
-//!         } => {
-//!             println!("The close button was pressed; stopping");
-//!             *control_flow = ControlFlow::Exit
-//!         },
-//!         Event::MainEventsCleared => {
-//!             // Application update code.
-//!
-//!             // Queue a RedrawRequested event.
-//!             window.request_redraw();
-//!         },
-//!         Event::RedrawRequested(_) => {
-//!             // Redraw the application.
-//!             //
-//!             // It's preferrable 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 (see the [`platform`] module), which in turn allows you
-//! to create an OpenGL/Vulkan/DirectX/Metal/etc. context that can be used to render graphics.

-//! ```
-//! 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 LoopDestroyed
-//!
-//! Keep in mind that after LoopDestroyed event is received every attempt to draw with
-//! opengl will result in segfault.
-//!
-//! Also note that app may not receive the LoopDestroyed event if suspended; it might be SIGKILL'ed.
