Summary: Pointer gestures are created for a pointer and there are two types of gestures: swipe and pinch. At a given time there can only be one active gesture. The implementation in SeatInterface ensures that there can only be one active gesture. Each gesture consists of a start event, 0 to multiple update events and an end event. The end can also be a cancel. To better support this the implementation doesn't follow the protocol and splits end and cancel into dedicated methods in the server side and into dedicated signals in the client side.
