…cognizers On tvOS, SDL installs UISwipeGestureRecognizers on the view so Apple TV remote swipes generate arrow-key events. When one recognizes, it cancels the in-progress touches, because the recognizers don't set cancelsTouchesInView = NO. Apps that read the remote touchpad's raw touch events directly (for example, absolute or relative pointer control) get their touch sequence cut off mid-gesture. Add SDL_HINT_APPLE_TV_REMOTE_SWIPE_GESTURES to gate installation of those recognizers. Default is "1", which keeps the current behavior. Set "0" to skip them and receive uninterrupted touch events.
