annotate Framework/Scene2DViewport/MeasureToolsToolbox.h @ 751:712ff6ff3c19
- undo redo now works fine for both measure tool creation commands
- added LayerHolder to streamline layer index management
- added overloads for ORTHANC_ASSERT with no string message (some heavy
preprocessor wizardry in there)
- fixing wasm BasicScene is *not* finished.
