App: Event processing tweak

Refresh events will never be dispatched (it would be pointless), but instead just set a flag that prevents SDL_WaitEvent() to be called.

SDL_WaitEvent() should never be called anyway because `pendingRefresh` is set, but this makes it clearer and skips other unnecessary checks.
