Previous version used [`SetTimer`] with `GetMessageW` for waiting.
The downside of UI timers like ones created by `SetTimer`,
is that they may be late by up to 15-16 ms.
To fix this behaviour, I added use of high resolution timers created by [`CreateWaitableTimerExW`] with the flag `CREATE_WAITABLE_TIMER_HIGH_RESOLUTION`.
In my previous experience, waiting on such timers have precision of roundly 0.5 ms which is the best available on Windows at the moment.
I use [`MsgWaitForMultipleObjectsEx`] to wait simultaneously for both timer and newly arriving events.
Unfortunately, high resolution timers are available only since Windows 10 1803. However:
1. Win 10 is already getting to the end of support, like all previous versions, so it is OK to rely on APIs introduced in it;
2. I use `dwMilliseconds` parameter of `MsgWaitForMultipleObjectsEx` as a fallback. It should perform not worse compared to waiting for events from `SetTimer`.
I also refactored code to remove event dispatching from function responsible for waiting for events. This provides more clear separations of concern and avoids unnecessary duplication of dispatching logic.
After [review] from @rib, I also moved the waiting itself from `wait_for_messages` method to separate function, so it is clearly seen that `wait_for_messages` do 3 things: notify app that we about to wait, wait, notify that we have new events.
I have tested behaviour using a egui app with Vulkan rendering with `VK_PRESENT_MODE_IMMEDIATE_KHR`, and older version consistently have twice less FPS than requested (e.g. 30 FPS when limit is 60 and 60 FPS when limit is 120) while newer version works more correctly (almost always 60 FPS when limit is 60, and only 5-10 frames missing when FPS is set to 120 or more).

Adds `WindowExtMacOS::set_unified_titlebar` and
`WindowAttributesExtMacOS::with_unified_titlebar`,
which allow you to use a larger titlebar style on macOS.
Key them off of `onStop()` and `onStart()` which seems to match the
other backends most closely. These [Android Activity lifecycle] events
denote when the application is visible on-screen, and recommend that any
heavy lifting for startup and shutdown happens here, as the application
may be demoted to the background and later shut down entirely unless the
user navigates back to it.

- Rename `CursorMoved` to `PointerMoved`.
- Rename `CursorEntered` to `PointerEntered`.
- Rename `CursorLeft` to `PointerLeft`.
- Rename `MouseInput` to `PointerButton`.
- Add `position` to every `PointerEvent`.
- Remove `Touch`, which is folded into the `Pointer*` events.
- New `PointerType` added to `PointerEntered` and `PointerLeft`,
signifying which pointer type is the source of this event.
- New `PointerSource` added to `PointerMoved`, similar to `PointerType`
but holding additional data.
- New `ButtonSource` added to `PointerButton`, similar to `PointerType`
but holding pointer type specific buttons. Use
`ButtonSource::mouse_button()` to easily normalize any pointer button
type to a generic mouse button.
- In the same spirit rename `DeviceEvent::MouseMotion` to `PointerMotion`.
- Remove `Force::Calibrated::altitude_angle`.

* Rename `WindowEvent::Resized` to `SurfaceResized`
* Rename `InnerSizeWriter` to `SurfaceSizeWriter`
* Replace `inner_size` with `surface_size`
* Rename `resize_increments` to `surface_resize_increments`
This should allow us to make future split of backends much easier.
The `Box<dyn Window>` is a _temporary_ solution, which will be
removed with the future updates when we decide on how the Window
should be stored.
Another one bites the dust.
This replaces the code dependent on libxcursor with equivalent code
written using x11rb, featuring its special "cursor" module.

This implements basic iOS IME support (typing, backspace, support for emojis
etc but no autocomplete or copy / paste menu).

- Change `OrientationData::natural` type from `bool` to `Orientation`, just telling the user what the natural orientation is.
- Fix and improve some monitor related documentation.
This allows the user to override the application delegate themselves,
which opens several doors for customization that were previously closed.
To do this, we use notifications instead of top-level application delegate
methods.
One effect of not providing an application delegate on iOS is that we no
longer act as-if the application successfully open all URLs there.
This is a breaking change, although unlikely to matter in practice, since the
return value of `application:didFinishLaunchingWithOptions:` is seldom used by
the system (and is likely the preferred behaviour anyhow).
Because we don't want to force all methods on `VideoModeHandle` to return `Option`, we decided to remove the already incomplete support in Android for both types.
`VideoModeHandle::refresh_rate_millihertz()` and `bit_depth()` now return a `Option<NonZero*>`.
`MonitorHandle::position()` now returns an `Option`.
On Orbital `MonitorHandle::name()` now returns `None` instead of a dummy name.
This also fixes macOS returning `None` in `Window::theme()` if no theme
override is set, instead it now returns the system theme.
MacOS and Wayland were the only ones working correctly according to the
documentation, which was an oversight. The documentation was "fixed"
now.
Fixes#3837.
We decided to remove them because they contained too little information
for the user to be useful. The assumption is that they were originally
implemented to enable gamepad support, which we already decided we are
not going to add directly to Winit.
This had no real use because we don't expose any information on
`DeviceId` except on Windows. But there we only expose the name. The
assumption is that this was originally added for gamepad support, which
never made it into Winit.
Requires getting permission from the user to get "detailed" support.
Also enables users to go fullscreen on specific monitors.
Exposes platform-specific orientation API.
Most functionality depends on browser support, currently only Chromium.
- Internal: Fix dropping `Notifier` without sending a result causing `Future`s to never complete. This should never happen anyway, but now we get a panic instead of nothing if we hit a bug.
- Internal: Remove a bunch of `unwrap()`s that aren't required when correctly using `MainThreadMarker`.
- `Window::canvas()` is now able to return a reference instead of an owned value.
Extracted from #3801.
Without smooth resizing, the window will appear to jitter when it is being
resized. This is because X11 completes the resize before the client gets a
chance to draw a new frame.
This is fixed by using the "sync" extension to ensure that the resize of the
X11 window is synchronized with the server.
Closes#2153
This allows the user more control over how they pass their application state
to Winit, and will hopefully allow `Drop` implementations on the application
handler to work in the future on all platforms.
