Setting the background color changes how the window title bar appears,
which is something that the application should customize itself if it
wants this behaviour (and also, it wasn't set when calling
`set_transparent`, so the behaviour wasn't consistent).
On Windows, it is generally unsafe to use the HWND outside of the thread
that it originates from. In reality, the HWND is an index into a
thread-local table, so using it outside of the GUI thread can result in
another window being used instead, following by code unsoundness. This
is why the WindowHandle type is !Send. However, Window is Send and Sync,
which means we have to account for this.
Thus far the best solution seems to be to check if we are not in the GUI
thread. If we aren't, refuse the return the window handle.
For users who want to ensure the safety themselves, the unsafe API
was added.

This replaces a reference to EventLoopBuilderExtUnix in a panic
message with EventLoopBuilderExtX11 or EventLoopBuilderExtWayland.

In rare cases destroying subsurfaces before the main surface could
result in a frame where the window is still shown, but decorations
got hidden, right before the window itself disappears.
Changes relevant to Winit:
- `icrate` has been deprecated in favour of separate crates per
framework, in our case `objc2-foundation` and `objc2-app-kit` (and in
the future `objc2-ui-kit` on iOS).
- Moved `MainThreadMarker::run_on_main` to free-standing function
`run_on_main`.
- Changed how features work, this should result in less code that we
need to compile.
- Enums are now real structs instead of type-aliases and free constants.
There are AV rules out there which cause almost any
program that contains github URLs to become marked as malware.
While those rules are spurious, they're years old, and AV vendors have a
very poor reputation at appropriately following up with these problems.
Remove these strings from the panic data present in the binary
prevents binaries linking the winit from being spuriously marked as
Trojan:Win32/Wacatac.B!ml.
In particular, we don't want to emit those events inside of
`pressureChangeWithEvent:`, since the mouse motion value is sometimes
outdated.
Additionally, we want to ensure the events have been emitted during
other gestures.

This fixes issues where a hidden and grabbed cursor could leave the
window and become visible on top of the windows taskbar (and potentially
leave the window altogether if the taskbar is clicked) under at least
two occasions:
- When a window is overlapping the taskbar.
- When a window is maximized and Automatically hide the taskbar has
been enabled.
This approach of confining the cursor to the center of the window is
used in SDL.
Add a simple `ApplicationHandler` trait since winit is moving towards
trait based API. Add `run_app` group of APIs to accept `&mut impl
ApplicationHandler` deprecating the old `run` APIs.

Invert the mouse delta filter, so it aligns with the intention of
filtering values lower than epsilon.

Tracing is a modern replacement for the log crate that allows for
annotating log messages with the function that they come from.

Usually, if mouse events are equal to (0, 0) we filter them out.
However, if the event is very close to zero it will still be given to
the user. In some cases this can be caused by bad float math on the X11
server side.
Fix it by filtering absolute values smaller than floating point epsilon.

Closes: #3500
* Convert usage of Lazy to OnceLock on macOS and iOS
* Remove a few uses of Lazy that wrapped Mutex or RwLock
The `new` functions on these were made `const` in Rust 1.63.0
* Use AtomicBool instead of RwLock
This makes our use of `unsafe` to make the event handler temporarily 'static be local to a module, in a way that's (hopefully) much easier to reason about.
Removes the once_cell dependency, instead using std::sync::OnceLock and a
minimal polyfill for std::sync::LazyLock, which may be stabilized soon
(see rust-lang/rust#121377).
This should not require a bump in MSRV, as OnceLock was stabilized in 1.70,
which this crate is using.
* Move platform-specific documentation to `winit::platform` module
* Document cargo features in crate docs
* Move version requirements to crate-level docs
Given that `ModifiersChanged` is a window event, it means that clients
may track it for each window individually, thus not sending it between
focus changes may result in modifiers getting desynced on the consumer
side.
Replace the `CustomCursorBuilder` with the `CustomCursorSource` and
perform the loading of the cursor via the
`EventLoop::create_custom_cursor` instead of passing it to the builder
itself.
This follows the `EventLoop::create_window` API.
Creating window when event loop is not running generally doesn't work,
since a bunch of events and sync OS requests can't be processed. This
is also an issue on e.g. Android, since window can't be created outside
event loop easily.
Thus deprecate the window creation when event loop is not running,
as well as other resource creation to running event loop.
Given that all the examples use the bad pattern of creating the window
when event loop is not running and also most example existence is
questionable, since they show single thing and the majority of their
code is window/event loop initialization, they wore merged into
a single example 'window.rs' example that showcases very simple
application using winit.
Fixes#3399.
Mainly fix typos in comments, but also some minor code changes:
* Rename `apply_on_poiner` to `apply_on_pointer`.
* Rename `ImeState::Commited` to `ImeState::Committed`
* Correct `cfg_attr` usage: `wayland_platfrom` -> `wayland_platform`.
While there's a separate event to deliver modifiers for keyboard,
unfortunately, it's not even remotely reflects the modifiers state.
Thus use events along side regular modifier updates to correctly
detect the state. Also, apply the modifiers from the regular
key event by converting their state to xkb modifiers state.
