Winit version 0.29.0-beta.0

The change to xinput2 completely disabled IME support, thus we've got
a dead keys reporting, because nothing was eating the key events
anymore, however that's not what we really need, given that not
working IME makes it impossible for some users to type.

The proper solution is to not use Xlib at all for that and rely on
xcb and its tooling around the XIM and text compose stuff, so
we'll have full control over what is getting sent to the XIM/IC or not.

Fixes #2888.

 # Unreleased
 
+# 0.29.0-beta.0
+
+- On Web, allow event loops to be recreated with `spawn`.
+- **Breaking:** Rename `Window::set_ime_position` to `Window::set_ime_cursor_area` adding a way to set exclusive zone.
+- On Android, changed default behavior of Android to ignore volume keys letting the operating system handle them.
+- On Android, added `EventLoopBuilderExtAndroid::handle_volume_keys` to indicate that the application will handle the volume keys manually.
+- **Breaking:** Rename `DeviceEventFilter` to `DeviceEvents` reversing the behavior of variants.
+- **Breaking:** Rename `EventLoopWindowTarget::set_device_event_filter` to `listen_device_events`.
+- On X11, fix `EventLoopWindowTarget::listen_device_events` effect being reversed.
+- **Breaking:** Remove all deprecated `modifiers` fields.
+- **Breaking:** Overhaul keyboard input handling.
+  - Replace `KeyboardInput` with `KeyEvent` and `RawKeyEvent`.
+    - Change `WindowEvent::KeyboardInput` to contain a `KeyEvent`.
+    - Change `Event::Key` to contain a `RawKeyEvent`.
+  - Remove `Event::ReceivedCharacter`. In its place, you should use
+    `KeyEvent.text` in combination with `WindowEvent::Ime`.
+  - Replace `VirtualKeyCode` with the `Key` enum.
+  - Replace `ScanCode` with the `KeyCode` enum.
+  - Rename `ModifiersState::LOGO` to `SUPER` and `ModifiersState::CTRL` to `CONTROL`.
+  - Add `KeyCode` to refer to keys (roughly) by their physical location.
+  - Add `NativeKeyCode` to represent raw `KeyCode`s which Winit doesn't
+    understand.
+  - Add `Key` to represent the keys after they've been interpreted by the
+    active (software) keyboard layout.
+  - Add `NativeKey` to represent raw `Key`s which Winit doesn't understand.
+  - Add `KeyLocation` to tell apart `Key`s which usually "mean" the same thing,
+    but can appear simultaneously in different spots on the same keyboard
+    layout.
+  - Add `Window::reset_dead_keys` to enable application-controlled cancellation
+    of dead key sequences.
+  - Add `KeyEventExtModifierSupplement` to expose additional (and less
+    portable) interpretations of a given key-press.
+  - Add `KeyCodeExtScancode`, which lets you convert between raw keycodes and
+    `KeyCode`.
+  - `ModifiersChanged` now uses dedicated `Modifiers` struct.
+- On Orbital, fix `ModifiersChanged` not being sent.
+- **Breaking:** `CursorIcon` is now used from the `cursor-icon` crate.
+- **Breaking:** `CursorIcon::Hand` is now named `CursorIcon::Pointer`.
+- **Breaking:** `CursorIcon::Arrow` was removed.
+- On Wayland, fix maximized startup not taking full size on GNOME.
+- On Wayland, fix initial window size not restored for maximized/fullscreened on startup window.
+- On Wayland, `Window::outer_size` now accounts for **client side** decorations.
+- On Wayland, fix window not checking that it actually got initial configure event.
+- On Wayland, fix maximized window creation and window geometry handling.
+- On Wayland, fix forward compatibility issues.
+- On Wayland, add `Window::drag_resize_window` method.
+- On Wayland, drop `WINIT_WAYLAND_CSD_THEME` variable.
+- Implement `PartialOrd` and `Ord` on types in the `dpi` module.
+- **Breaking:** Bump MSRV from `1.60` to `1.64`.
+- **Breaking:** On Web, the canvas output bitmap size is no longer adjusted.
+- On Web: fix `Window::request_redraw` not waking the event loop when called from outside the loop.
+- On Web: fix position of touch events to be relative to the canvas.
+- On Web, fix `Window:::set_fullscreen` doing nothing when called outside the event loop but during
+  a transient activation.
+- On Web, fix pointer button events not being processed when a buttons is already pressed.
+- **Breaking:** Updated `bitflags` crate version to `2`, which changes the API on exposed types.
+- On Web, handle coalesced pointer events, which increases the resolution of pointer inputs.
+- **Breaking:** On Web, `instant` is now replaced by `web_time`.
+- On Windows, port to `windows-sys` version 0.48.0.
+- On Web, fix pen treated as mouse input.
+- On Web, send mouse position on button release as well.
+- On Web, fix touch input not gaining or loosing focus.
+- **Breaking:** On Web, dropped support for Safari versions below 13.1.
+- On Web, prevent clicks on the canvas to select text.
+- On Web, `EventLoopProxy` now implements `Send`.
+- On Web, `Window` now implements `Send` and `Sync`.
+- **Breaking:** `WindowExtWebSys::canvas()` now returns an `Option`.
+- On Web, use the correct canvas size when calculating the new size during scale factor change,
+  instead of using the output bitmap size.
+- On Web, scale factor and dark mode detection are now more robust.
+- On Web, fix the bfcache by not using the `beforeunload` event and map bfcache loading/unloading to `Suspended`/`Resumed` events.
+- On Web, fix scale factor resize suggestion always overwriting the canvas size.
+- On macOS, fix crash when dropping `Window`.
+- On Web, use `Window.requestIdleCallback()` for `ControlFlow::Poll` when available.
+- **Breaking:** On Web, the canvas size is not controlled by Winit anymore and external changes to
+  the canvas size will be reported through `WindowEvent::Resized`.
+- On Web, respect `EventLoopWindowTarget::listen_device_events()` settings.
+- On Web, fix `DeviceEvent::MouseMotion` only being emitted for each canvas instead of the whole window.
+- On Web, add `DeviceEvent::Motion`, `DeviceEvent::MouseWheel`, `DeviceEvent::Button` and
+  `DeviceEvent::Key` support.
+- **Breaking** `MouseButton` now supports `Back` and `Forward` variants, emitted from mouse events
+  on Wayland, X11, Windows, macOS and Web.

+    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 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.

+- 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.

+- 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.

+- 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.

+- Derive `Ord` and `PartialOrd` for `VirtualKeyCode` enum.
+- On Windows, fix issue where hovering or dropping a non file item would create a panic.

+- 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.

+- 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, 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)

+# 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 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 1.64.
+- you tested your modifications on all the platforms impacted, or if not possible detail which platforms
+  were not tested, and what should be tested, so that a maintainer or another contributor can test them
+- you updated any relevant documentation in winit
+- you left comments in your code explaining any part that is not straightforward, so that the
+  maintainers and future contributors don't have to try to guess what your code is supposed to do
+- your PR adds an entry to the changelog file if the introduced change is relevant to winit users.
+
+  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 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 & Testers
+
+The current maintainers are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
+
+If you are interested in being pinged when testing is needed for a certain platform, please add yourself to the [Testers and Contributors](https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors) table!
+
+## 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 7+ (10+ is tested regularly)
+  - macOS 10.7+ (10.14+ is tested regularly)
+  - Unix
+    - via X11
+    - via Wayland
+  - Redox OS, via Orbital
+- Mobile
+  - iOS
+  - Android
+- Web
+  - via WASM
+
+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 gets 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 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.

+            _ => (),
         }
     });
 }
 ```
 
+Winit is only officially supported on the latest stable version of the Rust compiler.
+
+### Cargo Features
+
+Winit provides the following features, which can be enabled in your `Cargo.toml` file:
+* `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde).
+* `x11` (enabled by default): On Unix platform, compiles with the X11 backend
+* `wayland` (enabled by default): On Unix platform, compiles with the Wayland backend
+* `mint`: Enables mint (math interoperability standard types) conversions.
+
 ### Platform-specific usage
 
-#### Emscripten and WebAssembly
+#### Wayland
 
-Building a binary will yield a `.js` file. In order to use it in an HTML file, you need to:
+Note that windows don't appear on Wayland until you draw/present to them.
 
-- Put a `<canvas id="my_id"></canvas>` element somewhere. A canvas corresponds to a winit "window".
-- Write a Javascript code that creates a global variable named `Module`. Set `Module.canvas` to
-  the element of the `<canvas>` element (in the example you would retrieve it via `document.getElementById("my_id")`).
-  More information [here](https://kripken.github.io/emscripten-site/docs/api_reference/module.html).
-- Make sure that you insert the `.js` file generated by Rust after the `Module` variable is created.
+#### WebAssembly
+
+To run the web example: `cargo run-wasm --example web`
+
+Winit supports compiling to the `wasm32-unknown-unknown` target with `web-sys`.
+
+On the web platform, a Winit window is backed by a `<canvas>` element. You can
+either [provide Winit with a `<canvas>` element][web with_canvas], or [let Winit
+create a `<canvas>` element which you can then retrieve][web canvas getter] and
+insert it into the DOM yourself.
+
+For example code using Winit with WebAssembly, check out the [web example]. For
+information on using Rust on WebAssembly, check out the [Rust and WebAssembly
+book].
+
+[web with_canvas]: https://docs.rs/winit/latest/wasm32-unknown-unknown/winit/platform/web/trait.WindowBuilderExtWebSys.html#tymethod.with_canvas
+[web canvas getter]: https://docs.rs/winit/latest/wasm32-unknown-unknown/winit/platform/web/trait.WindowExtWebSys.html#tymethod.canvas
+[web example]: ./examples/web.rs
+[Rust and WebAssembly book]: https://rustwasm.github.io/book/
+
+#### Android
+
+The Android backend builds on (and exposes types from) the [`ndk`](https://docs.rs/ndk/0.7.0/ndk/) crate.
+
+Native Android applications need some form of "glue" crate that is responsible
+for defining the main entry point for your Rust application as well as tracking
+various life-cycle events and synchronizing with the main JVM thread.
+
+Winit uses the [android-activity](https://github.com/rib/android-activity) as a
+glue crate (prior to `0.28` it used
+[ndk-glue](https://github.com/rust-windowing/android-ndk-rs/tree/master/ndk-glue)).
+
+The version of the glue crate that your application depends on _must_ match the
+version that Winit depends on because the glue crate is responsible for your
+application's main entrypoint. If Cargo resolves multiple versions they will
+clash.
+
+`winit` glue compatibility table:
+
+| winit |       ndk-glue               |
+| :---: | :--------------------------: |
+| 0.28  | `android-activity = "0.4"`   |
+| 0.27  | `ndk-glue = "0.7"`           |
+| 0.26  | `ndk-glue = "0.5"`           |
+| 0.25  | `ndk-glue = "0.3"`           |
+| 0.24  | `ndk-glue = "0.2"`           |
+
+The recommended way to avoid a conflict with the glue version is to avoid explicitly
+depending on the `android-activity` crate, and instead consume the API that
+is re-exported by Winit under `winit::platform::android::activity::*`
+
+Running on an Android device needs a dynamic system library, add this to Cargo.toml:
+
+```toml
+[lib]
+name = "main"
+crate-type = ["cdylib"]
+```
+
+All Android applications are based on an `Activity` subclass and the
+`android-activity` crate is designed to support different choices for this base
+class. Your application _must_ specify the base class it needs via a feature flag:
+
+| Base Class       | Feature Flag      |  Notes  |
+| :--------------: | :---------------: | :-----: |
+| `NativeActivity` | `android-native-activity` | Built-in to Android - it is possible to use without compiling any Java or Kotlin code. Java or Kotlin code may be needed to subclass `NativeActivity` to access some platform features. It does not derive from the [`AndroidAppCompat`] base class.|
+| [`GameActivity`] | `android-game-activity`   | Derives from [`AndroidAppCompat`] which is a defacto standard `Activity` base class that helps support a wider range of Android versions. Requires a build system that can compile Java or Kotlin and fetch Android dependencies from a [Maven repository][agdk_jetpack] (or link with an embedded [release][agdk_releases] of [`GameActivity`]) |
+
+[`GameActivity`]: https://developer.android.com/games/agdk/game-activity
+[`GameTextInput`]: https://developer.android.com/games/agdk/add-support-for-text-input
+[`AndroidAppCompat`]: https://developer.android.com/reference/androidx/appcompat/app/AppCompatActivity
+[agdk_jetpack]: https://developer.android.com/jetpack/androidx/releases/games
+[agdk_releases]: https://developer.android.com/games/agdk/download#agdk-libraries
+[Gradle]: https://developer.android.com/studio/build
+
+For example, add this to Cargo.toml:
+```toml
+winit = { version = "0.28", features = [ "android-native-activity" ] }
+
+[target.'cfg(target_os = "android")'.dependencies]
+android_logger = "0.11.0"
+```
+
+And, for example, define an entry point for your library like this:
+```rust
+#[cfg(target_os = "android")]
+use winit::platform::android::activity::AndroidApp;
+
+#[cfg(target_os = "android")]
+#[no_mangle]
+fn android_main(app: AndroidApp) {
+    use winit::platform::android::EventLoopBuilderExtAndroid;
+
+    android_logger::init_once(android_logger::Config::default().with_min_level(log::Level::Trace));
+
+    let event_loop = EventLoopBuilder::with_user_event()
+        .with_android_app(app)
+        .build();
+    _main(event_loop);
+}
+```
+
+For more details, refer to these `android-activity` [example applications](https://github.com/rib/android-activity/tree/main/examples).
+
+##### Converting from `ndk-glue` to `android-activity`
+
+If your application is currently based on `NativeActivity` via the `ndk-glue` crate and building with `cargo apk` then the minimal changes would be:
+1. Remove `ndk-glue` from your `Cargo.toml`
+2. Enable the `"android-native-activity"` feature for Winit: `winit = { version = "0.28", features = [ "android-native-activity" ] }`
+3. Add an `android_main` entrypoint (as above), instead of using the '`[ndk_glue::main]` proc macro from `ndk-macros` (optionally add a dependency on `android_logger` and initialize logging as above).
+4. Pass a clone of the `AndroidApp` that your application receives to Winit when building your event loop (as shown above).
+
+#### MacOS
+
+A lot of functionality expects the application to be ready before you start
+doing anything; this includes creating windows, fetching monitors, drawing,
+and so on, see issues [#2238], [#2051] and [#2087].
+
+If you encounter problems, you should try doing your initialization inside
+`Event::NewEvents(StartCause::Init)`.
+
+#### iOS
+
+Similar to macOS, iOS's main `UIApplicationMain` does some init work that's required
+by all UI related code, see issue [#1705]. You should consider creating your windows
+inside `Event::NewEvents(StartCause::Init)`.

+#### Redox OS
+
+Redox OS has some functionality not present yet, that will be implemented when
+its orbital display server provides it.

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

-//! the fields of the `WindowBuilder` object before you create the window.
+//! # Event handling
 //!
-//! # Events 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.
 //!
-//! 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.
+//! You can retrieve events by calling [`EventLoop::run`][event_loop_run]. This function will
+//! dispatch events for every [`Window`] that was created with that particular [`EventLoop`], and
+//! will run until the `control_flow` argument given to the closure is set to
+//! [`ControlFlow`]`::`[`ExitWithCode`] (which [`ControlFlow`]`::`[`Exit`] aliases to), at which
+//! point [`Event`]`::`[`LoopDestroyed`] is emitted and the entire program terminates.
 //!
-//! The events generated by a window can be retreived from the `EventsLoop` the window was created
-//! with.
+//! Winit no longer uses a `EventLoop::poll_events() -> impl Iterator<Event>`-based event loop
+//! model, since that can't be implemented properly on some platforms (e.g web, iOS) and works poorly on
+//! most other platforms. However, this model can be re-implemented to an extent with
+//! [`EventLoopExtRunReturn::run_return`]. See that method's documentation for more reasons about why
+//! it's discouraged, beyond compatibility reasons.
 //!
-//! 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, WindowEvent};
-//! # use winit::EventsLoop;
-//! # let mut events_loop = EventsLoop::new();
+//! use winit::{
+//!     event::{Event, WindowEvent},
+//!     event_loop::EventLoop,
+//!     window::WindowBuilder,
+//! };
 //!
-//! loop {
-//!     events_loop.poll_events(|event| {
-//!         match event {
-//!             Event::WindowEvent { event: WindowEvent::Resized(w, h), .. } => {
-//!                 println!("The window was resized to {}x{}", w, h);
-//!             },
-//!             _ => ()
-//!         }
-//!     });
-//! }
-//! ```
+//! let event_loop = EventLoop::new();
+//! let window = WindowBuilder::new().build(&event_loop).unwrap();
 //!
-//! The second way is to call `events_loop.run_forever(...)`. As its name tells, it will run
-//! forever unless it is stopped by returning `ControlFlow::Break`.
+//! event_loop.run(move |event, _, control_flow| {
+//!     // ControlFlow::Poll continuously runs the event loop, even if the OS hasn't
+//!     // dispatched any events. This is ideal for games and similar applications.
+//!     control_flow.set_poll();
 //!
-//! ```no_run
-//! use winit::{ControlFlow, Event, WindowEvent};
-//! # use winit::EventsLoop;
-//! # let mut events_loop = EventsLoop::new();
+//!     // ControlFlow::Wait pauses the event loop if no events are available to process.
+//!     // This is ideal for non-game applications that only update in response to user
+//!     // input, and uses significantly less power/CPU time than ControlFlow::Poll.
+//!     control_flow.set_wait();
 //!
-//! events_loop.run_forever(|event| {
 //!     match event {
-//!         Event::WindowEvent { event: WindowEvent::CloseRequested, .. } => {
+//!         Event::WindowEvent {
+//!             event: WindowEvent::CloseRequested,
+//!             ..
+//!         } => {
 //!             println!("The close button was pressed; stopping");
-//!             ControlFlow::Break
+//!             control_flow.set_exit();
 //!         },
-//!         _ => ControlFlow::Continue,
+//!         Event::MainEventsCleared => {
+//!             // Application update code.
+//!
+//!             // Queue a RedrawRequested event.
+//!             //
+//!             // You only need to call this if you've determined that you need to redraw, in
+//!             // applications which do not always need to. Applications that redraw continuously
+//!             // can just render here instead.
+//!             window.request_redraw();
+//!         },
+//!         Event::RedrawRequested(_) => {
+//!             // Redraw the application.
+//!             //
+//!             // It's preferable for applications that do not render continuously to render in
+//!             // this event rather than in MainEventsCleared, since rendering in here allows
+//!             // the program to gracefully handle redraws requested by the OS.
+//!         },
+//!         _ => ()
 //!     }
 //! });
 //! ```
 //!
-//! 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.
+//! [`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 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::WindowBuilder::with_visible) and explicitly make the
+//! window visible only once you're ready to render into it.

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