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

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