diff OrthancStone/Sources/Scene2DViewport/LayerHolder.h @ 1606:874e178f34e9
- 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
