When EGL is used on some other thread than the thread that drives the main wl_display queue, the Wayland EGL dri2 implementation is vulnerable to a race condition related to display round trips and global object advertisements. The race that may happen is that after after a proxy is created, but before the queue is set, events meant to be emitted via the yet to be set queue may already have been queued on the wrong queue. In order to make it possible to avoid this race, wayland 1.11 introduced new API that allows creating a proxy wrapper that may be used as the factory proxy when creating new proxies via Wayland requests. The queue of a proxy wrapper can be changed without effecting what queue events emitted by the actual proxy will be queued on, while still effecting what default queue proxies created from it will have. By introducing a wl_display proxy wrapper and using this when performing round trips (via wl_display_sync()) and retrieving the global objects (via wl_display_get_registry()), the mentioned race condition is avoided.
