 * Touch Contact State Transitions

 *

 * ENGAGED -> UPDATE | INRANGE | INCONTACT -> ENGAGED

 * ENGAGED -> UP | INRANGE -> HOVERING

 * ENGAGED -> UP -> OUT_OF_RANGE

 * ENGAGED -> UP | CANCELED -> OUT_OF_RANGE

 *

 * HOVERING -> UPDATE | INRANGE -> HOVERING

 * HOVERING -> UPDATE -> OUT_OF_RANGE

 * HOVERING -> UPDATE | CANCELED -> OUT_OF_RANGE

 *

 * OUT_OF_RANGE -> DOWN | INRANGE | INCONTACT -> ENGAGED

 * OUT_OF_RANGE -> UPDATE | INRANGE -> HOVERING

 *

 * When a contact is in the "hovering" or "engaged" state, it is referred to as being "active".

 * "Hovering" contacts are in range of the digitizer, while "engaged" contacts are in range of

 * the digitizer and in contact with the digitizer surface. MS-RDPEI remotes only active contacts

 * and contacts that are transitioning to the "out of range" state; see section 2.2.3.3.1.1 for

 * an enumeration of valid state flags combinations.

 *

 * When transitioning from the "engaged" state to the "hovering" state, or from the "engaged"

 * state to the "out of range" state, the contact position cannot change; it is only allowed

 * to change after the transition has taken place.
