Fixed bug 2430 - Missing initialization of the variable 'centroid' inside SDL_GestureAddTouch
klose
File: SDL_gesture.c
Method: SDL_GestureAddTouch
When a new SDL_GestureTouch element is added to the global SDL_gestureTouch array the variable 'centroid' of the new element is not initialized.
The problem is that this variable is read isndie SDL_GestureProcessEvent when a SDL_FINGERDOWN event occurs.
