+// can not change if both objects are sleeping. eNOTIFY_TOUCH_FOUND should be sent nonetheless.
+// For this to work the following assumptions are made:
+// - On creation or if the pose of an actor is set, the pair will always be checked.
+// - If the scenario above does not apply, then a trigger pair can only be deactivated, if both actors are sleeping.
+// - If an overlapping actor is activated/deactivated, the trigger interaction gets notified
