+ * 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.
