The whole scrolling gesture is delivered to a single node, so if I do two-finger scroll, the gesture is started immediately when pressing the first finger and the node is picked there, even if the later-added second finger is far away and something in the center would have been expected to get the events. This may lead to crazy behavior like one two-finger gesture scrolls one node and rotates another one. When we start new scroll gesture at this moment new node will be picked and the strange behavior disappear. Please generate scroll gesture finished and started notifications when touch count changes.
