Direct map control start event. 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 it's better use the time received from the system rather than fill in the value during processing. While the kinematics only work for moving the map, not for rotation and scaling.
