Nolan Darilek 73e0ac26ca Various accessibility API updates. (#9989) ... # Objective `bevy_a11y` was impossible to integrate into some third-party projects in part because it insisted on managing the accessibility tree on its own. ## Solution The changes in this PR were necessary to get `bevy_egui` working with Bevy's AccessKit integration. They were tested on a fork of 0.11, developed against `bevy_egui`, then ported to main and tested against the `ui` example. ## Changelog ### Changed * Add `bevy_a11y::ManageAccessibilityUpdates` to indicate whether the ECS should manage accessibility tree updates. * Add getter/setter to `bevy_a11y::AccessibilityRequested`. * Add `bevy_a11y::AccessibilitySystem` `SystemSet` for ordering relative to accessibility tree updates. * Upgrade `accesskit` to v0.12.0. ### Fixed * Correctly set initial accessibility focus to new windows on creation. ## Migration Guide ### Change direct accesses of `AccessibilityRequested` to use `AccessibilityRequested.::get()`/`AccessibilityRequested::set()` #### Before ``` use std::sync::atomic::Ordering; // To access accessibility_requested.load(Ordering::SeqCst) // To update accessibility_requested.store(true, Ordering::SeqCst); ``` #### After ``` // To access accessibility_requested.get() // To update accessibility_requested.set(true); ``` --------- Co-authored-by: StaffEngineer <111751109+StaffEngineer@users.noreply.github.com>		2023-10-02 21:22:52 +00:00
