examples/osganimationviewer/AnimtkViewer.cpp: - add option to display bone (--drawbone) - dont crash if the file does not contains a AnimationManagerBase, display the content only examples/osganimationviewer/AnimtkViewerGUI.cpp: - adjust the path of image for the gui include/osgAnimation/Interpolator: - add warn message instead of old assert include/osgAnimation/Bone: src/osgAnimation/Skeleton.cpp: - change a method name to fit better with what it does. setMatrixInSkeletonSpace instead of setBoneInSkeletonSpace include/osgAnimation/Skinning: src/osgAnimation/RigGeometry.cpp: - add patch from Fabien Lavignotte to compute normal correctly include/osgAnimation/Sampler: - adjust behviour without assert, return 0 instead of crashing "
