30 * If the adaptor detects a long press gesture, then it should create an instance of this structure and
31 * send it to the Core.
33 * This gesture can be in four states:
34 * - POSSIBLE: When the user first puts their finger down - Core needs to hit test the down point.
35 * - STARTED: When the long-press gesture is actually detected.
36 * - FINISHED: When the user finally lifts all touches.
37 * - CANCELLED: If, after a down event, no long press is detected, or a system interruption.

45 * @param[in] state STARTED, when we detect a long press.
46 * FINISHED, when all touches are finished.

63 * This is the point, in screen coordinates, where the long press occurred.
64 * If a multi-touch tap, then this should be the centroid of all the touch points.
