From Cedric Pinson, "updated osgAnimation with the trunk here the update:

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
