       SoScale2UniformDragger is a simple dragger that scales uniformly in the x and y dimensions
       when dragged within the x-y plane with the mouse. The local space  is  determined  by  its
       location  in  the  scene graph. Transformation nodes placed before it will affect both the
       dragger and the plane of motion.

       This node has a scaleFactor field which always reflects its size in local  space.  If  you
       set  the field, the dragger will change accordingly.  You can also connect fields of other
       nodes or engines from this one to make them follow the dragger's motion.

       This dragger contains four parts, scaler, scalerActive, feedback, and feedbackActive.

       Each of these is set by default from a resource described in the Dragger Resource  section
       of  the  online reference page for this class. You can change the parts in any instance of
       this dragger using setPart().

       You can make your program use different default resources for the  parts  by  copying  the
       file  /usr/share/data/draggerDefaults/scale2UniformDragger.iv  into  your  own  directory,
       editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to
       that directory.


     SoSFVec3f           scaleFactor
          Scale factor affecting the dragger.



     static const SoNodekitCatalog *
                         getClassNodekitCatalog() const
          Returns an SoNodekitCatalog for this class

     static SoType       getClassTypeId()
          Returns type identifier for this class.
