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.
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`.
This fixes an issue when setting the position of the window on a new monitor and immediately maximizing it
```rs
window.set_outer_position::<PhysicalPosition<u32>>((2000, 200).into());
window.set_maximized(true);
```
Due to the nature of the event loop, the requested position and maximization state will apply correctly but due to the fact that the new position is a different monitor, a `ScaleFactorChanged` is emitted afterwards to the evenloop and a new size is set while the window is still maximized which results in a window that has `WS_MAXIMZE` window style but doesn't cover the whole monitor.
This was supposed to be rolled out with the rwh v0.6 update, but it
was left behind for some reason. I've added this type back.

* make `EventLoopWindowTarget` independent of UserEvent type
the `EventLoopWindowTarget` is needed for window creation. conceptually,
only `EventLoop` and `EventLoopProxy` need to be parameterized, and all
other parts of the backend should be agnostic about the user event type,
parallel to how `Event<T>` is parameterized, but `WindowEvent` is not.
this change removes the dependency on the type of user events from the
`EventLoopWindowTarget` for the Windows backend, but keep a phantom data
to keep the API intact. to achieve this, I moved the `Receiver` end of
the mpsc channel from `ThreadMsgTargetData` into `EventLoop` itself, so
the `UserEvent` is only passed between `EventLoop` and `EventLoopProxy`,
all other part of the backend just use unit type as a placeholder for
user events.
it's similar to the macos backend where an erased `EventHandler` trait
object is used so all component except `EventLoop` and `EventLoopProxy`
need to be parameterized. however `EventLoop` of the Windows backend
already use an `Box<dyn FnMut>` to wrap the user provided event handler
callback, so no need for an dedicated trait object, I just modified the
wrapper to replace the placeholder user event with real value pulled
from the channel. I find this is the approach which need minimum change
to be made to existing code. but it does the job and could serve as a
starting point to future Windows backend re-works.
* fix CI clippy failure.
* make UserEventPlaceholder a new type instead of alias
* invariance is maintained by top-level EventLoopWindowTarget<T>
this field is transitional and her to keep API compatibility only.
the correct variance and such is already ensured by the top-level
`EventLoopWindowTarget`, just use `PhantomData<T>` here.
There seems to be many PRs relating to this issue, but they don't include all
platforms and for some reason lost steam. This PR again tries to make this
feature happen, and does it for all desktop platforms (x11, wayland, macos,
windows, web).
I think the best user of this feature and the reason I'm doing this is Bevy and
game engines in general. There non laggy hardware cursors with custom images are
very important. Game devs also like their PNGs so supporting platform native
cursor files is not that important, but I guess could be added too.

While working with device events, I noticed that there was an inconsistency in the mouse button device events between Windows/X11 and for example web, because web uses the same ids/order as the MouseButton enum, and Windows/X11 are using the X11 ids, and hwheel device event was ignored on Windows.
Mouse button device events are now using the same order as the MouseButton enum, and I also added hwheel device events for Windows.
When calling `Window::request_redraw` from the `RedrawRequested`
handler the `RedrawWindow` won't result in `WM_PAINT` being delivered
due since user callback is run before `DefWindowProcW` is called.
Track whether the user called `Window::request_redraw` and ask for
`RedrawWindow` after running the said function during `WM_PAINT`
handling.
Fixes#3150.
Split `Key` into clear categories, like `Named`, `Dead`, Character`, `Unidentified`
removing the `#[non_exhaustive]` from the `Key` itself.
Similar action was done for the `KeyCode`.
Fixes: #2995

Window builder is always accessed by winit on the thread event loop
is on, thus it's safe to mark the data it gets as `Send + Sync`.
Each unsafe object is marked individually as `Send + Sync` instead
of just implementing `Send` and `Sync` for the whole builder.
Add a method to request a system menu. The implementation
is provided only on Windows for now.
