gyurixandBrandon Thomas f5452cf126 Linux: prefer server DPI over panel physical DPI in vendored winit (#1150)
* fix(x11): prefer server DPI over panel physical DPI in winit

Without Xft DPI, use the X server screen dimensions before the output physical density. Xorg can run a dense panel at 96 DPI; EDID sizes alone make only winit apps appear zoomed.

Supersedes #908: preserves Xft.dpi priority, configured HiDPI screens, and WINIT_X11_SCALE_FACTOR override (including randr). Falls back to RandR output density when server dimensions are missing.

Adds default_dpi_factor() with 4 unit tests plus vendored-copy guard test in apps/pdfcraft/tests/winit_x11_dpi.rs.

* vendor/README: record the winit X11 DPI patch as (11)

Usage

Winit is a window creation and management library. It can create windows and lets you handle events (for example: the window being resized, a key being pressed, a mouse movement, etc.) produced by the window.

Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to show something on the window you need to use the platform-specific getters provided by winit, or another library.

CONTRIBUTING

For contributing guidelines see CONTRIBUTING.md.

MSRV Policy

This crate's Minimum Supported Rust Version (MSRV) is 1.70. 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.

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 same MSRV policy.
