Message : Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
