Winit version 0.29.6

This code confused me. I tried to understand it. I tried to simplify it
while keeping the functional style. But in the end, this just seems too
complicated for its own good. Just doing the exact same thing with a
match statement and the question mark operator makes it sooo much more
obvious what is happening.

+- On Windows, add support for `Window::set_transparent`.
+- On macOS, fix deadlock when entering a nested event loop from an event handler.

+- **Breaking:** `ScaleFactorChanged` now contains a writer instead of a reference to update inner size.
+- **Breaking** `run() -> !` has been replaced by `run() -> Result<(), EventLoopError>` for returning errors without calling `std::process::exit()` ([#2767](https://github.com/rust-windowing/winit/pull/2767))
+- **Breaking** Removed `EventLoopExtRunReturn` / `run_return` in favor of `EventLoopExtPumpEvents` / `pump_events` and `EventLoopExtRunOnDemand` / `run_on_demand` ([#2767](https://github.com/rust-windowing/winit/pull/2767))

+## MSRV Policy
+
+This crate's Minimum Supported Rust Version (MSRV) is **1.65**. Changes to
+the MSRV will be accompanied by a minor version bump.
+
+As a **tentative** policy, the upper bound of the MSRV is given by the following
+formula:
+
+```
+min(sid, stable - 3)
+```
+
+Where `sid` is the current version of `rustc` provided by [Debian Sid], and
+`stable` is the latest stable version of Rust. This bound may be broken in case of a major ecosystem shift or a security vulnerability.
+
+[Debian Sid]: https://packages.debian.org/sid/rustc
+
+The exception is for the Android platform, where a higher Rust version
+must be used for certain Android features. In this case, the MSRV will be
+capped at the latest stable version of Rust minus three. This inconsistency is
+not reflected in Cargo metadata, as it is not powerful enough to expose this
+restriction.
+
+All crates in the [`rust-windowing`] organizations have the

 //!   details.
-//! - **macOS:** Recent versions of macOS allow the user to change the scaling factor for certain
-//!   displays. When this is available, the user may pick a per-monitor scaling factor from a set

+//!   but the specific value varies across devices.
 //! - **X11:** Many man-hours have been spent trying to figure out how to handle DPI in X11. Winit
 //!   currently uses a three-pronged approach:
-//!   + Use the value in the `WINIT_X11_SCALE_FACTOR` environment variable, if present.
+//!   + Use the value in the `WINIT_X11_SCALE_FACTOR` environment variable if present.
 //!   + If not present, use the value set in `Xft.dpi` in Xresources.
 //!   + Otherwise, calculate the scale factor based on the millimeter monitor dimensions provided by XRandR.
 //!
 //!   If `WINIT_X11_SCALE_FACTOR` is set to `randr`, it'll ignore the `Xft.dpi` field and use the
 //!   XRandR scaling method. Generally speaking, you should try to configure the standard system
 //!   variables to do what you want before resorting to `WINIT_X11_SCALE_FACTOR`.
-//! - **Wayland:** On Wayland, scale factors are set per-screen by the server, and are always
-//!   integers (most often 1 or 2).
+//! - **Wayland:** The scale factor is suggested by the compositor for each window individually. The
+//!   monitor scale factor may differ from the window scale factor.
 //! - **iOS:** Scale factors are set by Apple to the value that best suits the device, and range
