void Impala::Core::Tracking::TrackerGeneralised::Clip ( Position & pos ) [inline, protected]

Actually we shouldn't clip at all, rather we should handle the situation that the object is (partially) outside the scene, when updating the object and when searching.

Todo:: take rotation and scale into consideration.

danger: - if the new rectangle lies outside the image, ObjectRepresentation::Reset and SearcherBase::Reset, might have problems
