Hi Robert,

This is good news! I've just been experimenting osgManipulator for the purpose of integrating it into our application. However, I had a big issue with the fact that draggers only could update Selection nodes. Thanks for changing this.

I particularily like that it's now possible to add custom dragger callbacks, because I'd like some draggers to update PAT and Auto transforms as well.

I just ran my test program against the changes you made to trunk, and everything seemed to work fine. Disclaimer: this is not an extensive test though, but at least the rewamped CommandManager/Selection classes didn't break anything.

I vote for removing them! The code change is relatively minor to experienced OSG users, while OSG beginners will benefit from a less confusing API.
