Based on https://github.com/rust-windowing/winit/pull/3973, which should be merged first.
There's an API to programmatically specify X11 screen id (override what is determined from the `DISPLAY` env variable), but it doesn't work.
Seeting up X Server with 2 screens and calling `DISPLAY=:0 X11_SCREEN_ID=1 cargo run --example window` should be equivalent to calling `DISPLAY=:0.1 cargo run --example window`
The latter works (and places the window on the correct screen), but the former yields
`failed to create initial window: Os(OsError { line: 620, file: "src/platform_impl/linux/x11/window.rs", error: X11Error(X11Error { error_kind: Match, error_code: 8, sequence: 219, bad_value: 1319, minor_opcode: 0, major_opcode: 1, extension_name: None, request_name: Some("CreateWindow") }) })`
_Here `1319` is the root window id for screen 0, which doesn't match the screen 1 that we request._
The problem is that we need to factor in the screen id when determining the parent (root) window when not explicitly set. This patch does that.

Also: Extend the window example with X11_{SCREEN,VISUAL}_ID env variables
Whether the pointer event is primary or not generally matters for the
context where all input is done by the same event, so users can
_ignore_ non-primary events since they are likely from users clicking
something else with their other fingers.
Having it only on a FingerId made it useless, since it's usually used
to avoid multi-touch, but if you start mapping on touch event you
already can track things like that yourself.
Fixes#3943.

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.

WindowId is a window _identifier_, and as such doesn't store anything
(unlike a _handle_). So we can safely make only be defined once, in the
core crate.
There are a few backends where we still use `into_raw` internally; I
consider these patterns discouraged, we should not be passing around
important state in the window id.
- 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`.

As discussed in today's meeting, this commit creates two tiers of
support. Tier 1, which is what we actively test, and Tier 2, what we
hope compiles.

* 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.
This makes it so, when X11 fails to initialize due to not loading a
library, it provides more verbose information on what exactly happened.

Another one bites the dust.
This replaces the code dependent on libxcursor with equivalent code
written using x11rb, featuring its special "cursor" module.

A panic doesn't really put any of the fields in XConnection into an invalid
state, so there is no real reason to panic when poisoning is detected.
So just ignore the poison.

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

* Update version docs to link to `rustc`'s supported versions
* Document how to run Winit on Mac Catalyst
* Improve instructions for building iOS applications
The old instructions are outdated, and suggested a workaround that is
unnecessary.
The user-story in the ecosystem is sadly not very clear-cut, so the
instructions here are still woefully incomplete.
* iOS: Clean up notes on main thread safety
These platform-specific notes on `Window` methods were unnecessary, as
it's already discussed in the top-level `Window` docs.
Instead of storing the event handler within the AppState, and extracting
it our every time we need it, we now use the same event handling
implementation as for macOS that ensures we don't re-entrantly call the
event handler, and that we un-register the handler again after we're
done using it (`UIApplicationMain` won't return, but may still unwind,
so this is very important for panic safety).
- 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).
This removes the direct requirement to implement `as_any` and it could
be just derived.
Also implement HasDisplayHandle for dyn ActiveEventLoop + '_.

This was implemented for `&dyn ActiveEventLoop` before, but that's less
general than implementing it directly for `dyn ActiveEventLoop`.
The `+ '_` is required to tell the compiler that we want to implement
this for all `dyn ActiveEventLoop`s, not just `'static` ones (even
though they're all going to be `'static`).
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.
