/*! This method overrides the same method from the base class SLSceneView.
 Most events such as all mouse and keyboard events from the OS are forwarded to
 SLSceneview. SLSceneview implements a default behaviour. If you want a
 different or additional behaviour for a certain eventhandler you have to sub-
 class SLSceneView and override the eventhandler.
 Because all video processing (capturing and calibration) is handled outside
 of the core SLProject we need to add an additional handling for mouse down
 withing the calibration routine.
