       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
