* 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.
