Fixed bug 2418 - Structure SDL_gestureTouch leaking


Structure SDL_gestureTouch gets reallocated for every new added gesture but its never freed.

Proposed patch add the function SDL_GestureQuit() that takes care of doing that and gets called when TouchQuit is called.

Gabriel Jacobo

Thanks for the patch. I think it needs a bit of extra work though, looking at the code in SDL_gesture.c , I see that SDL_numGestureTouches only goes up, I think the right fix here involves adding SDL_GestureDelTouch (hooked into SDL_DelTouch) as well as SDL_GestureQuit (as you posted in your patch).
