I actually made a mistake when creating the previous patch file... I forgot to include a crucial line which changed.
I've attached a new patch which just changes the line I forgot, since the other part has already been applied to the repository.
I tested this one by doing a clean rebuild of SDL, and it works with the new patch.
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.
