 - Remove `MonitorHandle::size()` and `refresh_rate_millihertz()` in favor of
   `MonitorHandle::current_video_mode()`.
 - On Android, remove all `MonitorHandle` support instead of emitting false data.
+- Remove `impl From<u64> for WindowId` and `impl From<WindowId> for u64`. Replaced with
+  `WindowId::into_raw()` and `from_raw()`.
