1. In explore-by-touch when the user slides two fingers in the same direction we consider it a drag gesture. We merge the pointers into one and deliver a touch event. When one of the pointers goes up we were transitioning into touch exploring state. This means that were transitioning to another state in the middle of a gesture which creates complications and leads for interaction end event not being sent. This change transitions out of dragging state when all pointers go up - simple and all events are properly sent. Consequentially, staring a drag the user has to lift all pointers to touch explore. Since usually users either drags or touch explores this seems the simplest and *least risky* fix. bug:7253731 Change-Id: Ie8588fbe9b26cb81312bd7fd377c94732e41e3f8
