Well, if you want to drag objects around you need to know how far away they are
to move them accordingly.
Most -f the code for that is actually in the TrackballNavigator, just used the
inverse way (it moves the camera so that the object stays under the mouse
cursor
when you click-n-drag with the middle mouse button). You might want to look at
that for some inspiration.
Hope it helps
Dirk
