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.

|
|
* In general these hints are just that - they may or may not be

|
* supported or applicable on any given platform, but they provide
|
|
* a way for an application or user to give the library a hint as
|
|
* to how they would like the library to work.
