The current implementation of the event loop runner has some significant
problems. It can't handle multiple events being emitted at once (for
example, when a keyboard event causes a key input, a text input, and a
modifier change.) It's also relatively easy to introduce bugs for the
different possible control flow states.
The new model separates intentionally emitting a NewEvents (poll
completed, wait completed, init) and emitting a normal event, as well as
providing a method for emitting multiple events in a single call.
* Don't discard high-precision cursor position data
Most platforms (X11, wayland, macos, stdweb, ...) provide physical
positions in f64 units, which can contain meaningful fractional
data. For example, this can be empirically observed on modern X11
using a typical laptop touchpad. This is useful for e.g. content
creation tools, where cursor motion might map to brush strokes on a
canvas with higher-than-screen resolution, or positioning of an object
in a vector space.

* Fix bug causing RedrawRequested events to only get emitted every other iteration of the event loop.
* Initialize simple_logger in examples.
This PR's primary bug was discovered because a friend of mine reported
that winit was emitting concerning log messages, which I'd never seen
since none of the examples print out the log messages. This addresses
that, to hopefully reduce the chance of bugs going unnoticed in the
future.
* Add changelog entry
* Format
* Rename hidpi_factor to scale_factor
* Deprecate WINIT_HIDPI_FACTOR environment variable in favor of WINIT_X11_SCALE_FACTOR
* Rename HiDpiFactorChanged to DpiChanged and update docs
I'm renaming it to DpiChanged instead of ScaleFactorChanged, since I'd
like Winit to expose the raw DPI value at some point in the near future,
and DpiChanged is a more apt name for that purpose.

* On X11, make `WINIT_HIDPI_FACTOR` dominate `Xft.dpi` in some cases
This commit makes `WINIT_HIDPI_FACTOR` dominate `Xft.dpi` in general and
adds a special value `0` for `WINIT_HIDPI_FACTOR` to use winit computed
DPI factor with randr over Xft.dpi.
* Use `randr` instead of `0` for auto dpi scaling
* Update CHANGELOG
* blow up on wrong env var
* Allow empty string for env var
* Move DeviceEvent handling to the message target window.
Previously, device events seem to have only been sent to one particular
window, and when that window was closed Winit would stop receiving
device events. This also allows users to create windowless event loops
that process device events - an intriguing idea, to say the least.

* Only issue `RedrawRequested` on final `Expose` event
Mutter can reposition window on resize, if it is behind mutter's "bounding box".
So, when you start winit window in maximized mode with CSD, mutter places its CSD
behind the GNOME's status bar initially, and then sends configure with the
exact same size as your current window. If winit decides to optimize calling
frame.resize(..) in this case, we won't call set_geometry(we're calling
it through resize) and GNOME won't reposition your window to be inside the
"bounding box", which is not a desired behavior for the end user.

* Clarify code with comments

* Syncs modifier state with state data in X key/button/motion events.
* Fixes modifier state in XWayland, as xinput2 raw input events will
not be received when a window does not have focus.
* Removes `impl From<_> for ModifiersState` on X11/Wayland API types,
replacing them with `pub(crate)` methods.
* Cleanup modifier state update using a macro
* Remove keys from modifier state when updating
* X11: Fix window creation hangs when another application is fullscreen
Previously, the X11 backend would block until a `VisibilityNotify` event
is received when creating a Window that is visible or when calling
`set_visible(true)` on a Window that is not currently visible. This
could cause winit to hang in situations where the WM does not quickly
send this event to the application, such as another window being
fullscreen at the time.
This behavior existed to prevent an X protocol error caused by setting
fullscreen state on an invisible window. This fix instead stores desired
fullscreen state when `set_fullscreen` is called (iff the window is not
visible or not yet visible) and issues X commands to set fullscreen
state when a `VisibilityNotify` event is received through the normal
processing of events in the event loop.
* Add window_debug example to facilitate testing
* Add a CHANGELOG entry
* Call `XUnmapWindow` if `VisibilityNotify` is received on an invisible window
* Prevent EventLoop from getting initialized outside the main thread
This only applies to the cross-platform functions. We expose functions
to do this in a platform-specific manner, when available.
* Add CHANGELOG entry
* Formatting has changed since the latest stable update...
* Fix error spacing
* Unix: Prevent initializing EventLoop outside main thread
* Updates libc dependency to 0.2.64, as required by BSD platforms
* Update CHANGELOG.md for Linux implementation
* Finish sentence
* Consolidate documentation
* Fix so the compiler can infer msg_send! return type
Currently, due to a quirk in Rust's type inference interacting with the
structure of the msg_send! macro, a () return type will be inferred when
the compiler cannot otherwise determine the return type. This behavior
is expected to change, and in the future could resolve to a ! return
type, which results in undefined behavior.
Linting has previously been added for this in rust-lang/rust#39216, but
it did not catch these cases due to SSheldon/rust-objc#62. An upcoming
version of objc will be fixed to stop hiding these errors, at which
point they will become compile errors.
This change fixes these errors and allows winit to compile with the
fixed version of objc.
* Bump cocoa to 0.19.1
Adds fullscreen using native web APIs to the stdweb and web-sys backends.
Due to limitations of browser APIs, requests for fullscreen can only be fulfilled during a short-lived user-triggered event. This commit does automatically handle that under the hood, but it does introduce unavoidable latency in full-screening the canvas.

Just before starting to poll/wait on calloop(mio), check if there
are already events pending in the internal buffer of our wayland
event queue. If so, dispatch them and force an instant wakeup from
the polling, in order to behave as if we were instantly woken up by
incoming wayland events.
When using OpenGL, mesa shares our wayland socket, and also reads
from it, especially if vsync is enabled as it'll do blocking reads.
When doing so, it may enqueue events in the internal buffer of our
event queue.
As the socket has been read, mio will thus not notify it to calloop
as read, and thus calloop will not know it needs to dispatch. In some
cases this can lead to some events being delivered much later than
they should. Combined with key repetition this can actually cause some
flooding of the event queue making this effect event worse.

`EventLoopProxy<T>` allows sending `T` from an arbitrary thread that
owns the proxy object. Thus, if `T` is `!Send`, `EventLoopProxy<T>` must
not be allowed to leave the main thread.
`EventLoopProxy<T>` uses `std::sync::mpsc::Sender` under the hood,
meaning the `!Sync` restriction of it also applies to
`EventLoopProxy<T>`. That is, even if `T` is thread-safe, a single
`EventLoopProxy` object cannot be shared between threads.
