Event of starting the direct map control. Tells the map to handle direct map control events. Direct control events only work from DirectMapControlBeginEvent to DirectMapControlEndEvent. After the direct control event sequence has ended, kinematics may start. Kinematics uses the time the event occurred, so using the time received from the system is better than filling in the value during processing. Kinematics works only for moving the map, not for rotation and scaling.
