DESCRIPTION
     SoTrackballManip is derived from SoTransform (by way of
     SoTransformManip). When its fields change, nodes following it in the
     scene graph rotate, scale, and/or translate.

     As a subclass of SoTransformManip, this manipulator also has a 3D
     interface to edit some of its fields. In this case, the interface edits
     the rotation and scaleFactor fields.

     A manipulator differs from a dragger. When you move a dragger, no other
     nodes are affected. When you move an SoTransformManip, other nodes move
     along with it. (See the reference page for SoTransformManip).

     The interface for an SoTrackballManip is exactly the same as that of the
     SoTrackballDragger. To find out more about the interface, see the
     reference page for SoTrackballDragger. To find out how the manipulator
     uses a dragger to provide its interface, see the reference page for
     SoTransformManip.

     On screen, this manipulator will surround the objects influenced by its
     motion. This is because it turns on the surroundScale part of the dragger
     (See the reference page for SoSurroundScale)

FUNCTIONS
     SoTrackballManip *	 SoTballManipCreate()
