Normally, a recognizer competes directly in the GestureArenaManager to recognize a sequence of pointer events as a gesture. With a GestureArenaTeam, recognizers can compete in the arena in a group with other recognizers.
When gesture recognizers are in a team together, then once there are no other competing gestures in the arena, the first gesture to have been added to the team automatically wins, instead of the gestures continuing to compete against each other.
For example, Slider uses this to support both a HorizontalDragGestureRecognizer and a TapGestureRecognizer, but without the drag recognizer having to wait until the user has dragged outside the slop region of the tap gesture before triggering. Since they compete as a team, as soon as any other recognizers are out of the arena, the drag recognizer wins, even if the user has not actually dragged yet. On the other hand, if the tap can win outright, before the other recognizers are taken out of the arena (e.g. if the slider is in a vertical scrolling list and the user places their finger on the touch surface then lifts it, so that neither the horizontal nor vertical drag recognizers can claim victory) the tap recognizer still actually wins, despite being in the team.
