Event, input source, error, data transfer, native key, IME request,
scroll delta and fullscreen enums can now gain variants without a
breaking change. Backends and examples get wildcard arms where they
matched exhaustively; unknown IME requests are reported as
ImeRequestError::NotSupported and unknown fullscreen modes behave
like Fullscreen::Borderless(None).
Apps need per-click decisions to follow the macOS convention of accepting
first mouse for low-risk actions (selection, scrolling) but rejecting it
for buttons and destructive actions. Motivated by slint-ui/slint#10451.
Always return `true` from `acceptsFirstMouse:`, and tag the resulting
`PointerButton` events with `is_macos_activation_click: true` (on both
the activating left press and its matching release) so the app can
short-circuit the whole gesture with a single check:
WindowEvent::PointerButton { is_macos_activation_click: true, .. } => return,
Replaces an earlier callback-based design (`accepts_first_mouse` on
`ApplicationHandlerExtMacOS`) that mapped more closely to AppKit but
didn't fit winit's event-driven model and required re-entrancy handling.
Also removes `WindowAttributesMacOS::with_accepts_first_mouse`, which is
now redundant — apps that want to reject activation clicks check the
flag on the per-event instead.
Add `WindowAttributesMacOS::with_fullscreen_auxiliary` and
`WindowExtMacOS::set_fullscreen_auxiliary` / `fullscreen_auxiliary`,
exposing `NSWindowCollectionBehaviorFullScreenAuxiliary`.
An auxiliary window can be shown on the same Space as a fullscreen
window. Without this, ordering a new window on screen while another
window of the application is fullscreen on the active Space makes macOS
switch Spaces or attempt Split View tiling, which flickers and can
abort the fullscreen state. This affects any application that opens
secondary windows (palettes, inspectors, tool windows) from a
fullscreen main window; see e.g.
https://github.com/emilk/egui/issues/8259 for a downstream bug caused
by this.
The attribute is applied in `new_window` so the collection behavior is
already in place when the window is first ordered on screen, which is
required for the fullscreen Space to remain undisturbed (and is not
achievable through the runtime setter, since winit shows the window
during creation).
Since `toggleFullScreen:` is silently ignored by AppKit on windows with
the auxiliary collection behavior, `set_fullscreen` now warns and bails
out early on such windows instead of recording a fullscreen state that
never materializes.

Implement proper decorationless popups by specifying the type of the child window with with_type()
With this commit, different kind of child windows can be created
- Popups: Special windows without any decoration which can be positioned relative to the parent
- Window: Normal window with a parent or not
The type can be specified during creation of the Window using the window_attributes and the with_type() function. As default a normal Window is used. If Popup is choosen a parent must be specified, otherwise the Popup creation fails with an Error returned by the new() function.

This commit implements a new API for drag and drop, with a `DataTransfer` type which abstracts over the various clipboard/drag and drop APIs across different platforms. I built this on top of #2429 although admittedly I ended up removing pretty much all of their work while I was reworking the design.
This is being built in order to help support [drag-and-drop work](https://github.com/slint-ui/slint/issues/1967) in Slint's winit backend. As part of that work, I did extensive research on how drag-and-drop and clipboard APIs are implemented across different platforms, and wrote a (still WIP) research document that can be found [here](https://gist.github.com/eira-fransham/06750cf8d25ade08d362a0ca8dfafe06).
The new API is inspired by the browser's [`DataTransfer`](https://developer.mozilla.org/en-US/docs/Web/API/DataTransfer) API.
wl_surface::set_buffer_scale is available since version 3. Sending it
on an older surface is a protocol error that terminates the connection.
This could happen when setting a custom cursor on a compositor without
wp_viewporter. The neighboring damage call already checks the version.
Resolver 3 skips dependency versions whose rust-version is above
ours, so the CI lockfile step no longer needs --precise pins that
must be maintained by hand.
This is also more reliable as more crate are release with higher MSRV

`setMarkedText:selectedRange:replacementRange:` converted the IME's UTF-16
`selectedRange` into UTF-8 byte offsets by taking `substringToIndex:` prefixes
and measuring them with `NSString::len()`
(`lengthOfBytesUsingEncoding:NSUTF8StringEncoding`). When an index falls inside
a surrogate pair, the prefix ends in a lone high surrogate, which UTF-8 cannot
represent, so `lengthOfBytesUsingEncoding:` returns 0 for the entire prefix and
the offset silently collapses to 0.
By using `OwnedDisplayHandle`, which uses reference-counting, instead of
`DisplayHandle<'static>` (where the user has to guarantee that the
Application doesn't outlive the event loop).
Any winit app on Windows freezes when the keyboard layout is switched by
tools such as Punto Switcher. A minidump of the frozen process shows the
main thread blocked in MsgWaitForMultipleObjectsEx (winit's event-loop
wait), re-entered during message dispatch through the switcher's injected
global hook (pshook64.dll, via CallNextHookEx) — a re-entrant Win32
message-loop wait, not a mutex deadlock (no LAYOUT_CACHE frames present).
Handle WM_INPUTLANGCHANGE to refresh the cached keyboard layout, then
defer to DefWindowProc so the message still propagates to first-level
child windows as the Win32 docs require. The cache refresh is the minimal
change that stops the freeze (verified on Windows 11 by isolation
variants); update_modifiers and swallowing the message are not needed.
Remove the matrix in the CI action; EmbarkStudios/cargo-deny#324 hasn't been resolved yet, but since we've split Winit out into multiple crates, there's still value in minimizing dependency conflicts even if they won't be hit by users, since e.g. Rust-Analyzer will by default check the entire workspace (and thus download and compile duplicate dependencies).
Most events in AppKit go through `sendEvent:`, and they contain a lot of
information, so it's nice to surface this when debugging.
We could override `sendEvent:` in UIKit and track this in there too, but
that's much less important, since there the relevant events are fairly
narrowly scoped, see the link below, other events go through CFRunLoop.
