diff Samples/Common/MeasureTools.h @ 632:500c3f70b6c2
- Added a ClearAllChains method to PolylineSceneLayer --> revision must change
when calling it ==> BumpRevision has been added to base class
- Added some docs
= Added GetMinDepth + GetMaxDepth to Scene2D (to alleviate the need for app-
specific "Z depth registry" : clients may simply add a new layer on top or at
the bottom of the existing layer set.
- Added the line tracker measurement tools, commands and trackers. Generic base
classes + Line measure
- started work on the line measure handles
