- ViewportController now has weak ptr to Viewport - Measuring tools + related commands and all trackers now store only a weak_ptr to the Viewport and lock() on demand for usage - LayerHolder and FixedPoint aligner store only a weak_ptr to the Viewport, too - Fixed float/double warning in GrayscaleWindowingSceneTracker
