v4: - Remove global `myARGV` and `myARGC` - Remove `dwFlags` and `wShowWindow` assigmnents. - Add a helper function to start child process. - Merge patches 2 and 3 into one. - Move event processing from `X11DRV_GetCurrentDisplaySettings` to `xrandr14_get_id`. - Only process RRNotify events. - Update commit message with the correct performance info for `EnumDisplaySettingsExW` (the previous one was messed up by CPU frequency scaling).
