* This is an example from the Inventor Toolmaker,

*
* Header file for "RotTransDragger"
*
* This is the source file for the RotTransDragger.
* It is a compound dragger which allows independent rotation
* in the x,y,and z directions as well as translation along a
* line. It is an example of how to write a compound dragger.
*
* It is composed of a TranslateRadialDragger and
* 3 SoRotateCylindricalDraggers bound into one dragger.
*
* Clicking on the TranslateRadialDragger piece results in a
* translational motion along the line formed by the center of
* the dragger and the point on the dragger that was hit.
*
* Clicking a cylinder rotator results in a rotation about
* either the x,y,or z axis.
*
* Geometry resources and part names for this dragger:
