DESCRIPTION
     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
     SoDraggerSetPart().

     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.

FIELDS
     SoSFVec3f		 scaleFactor
	  Scale factor affecting the dragger.

FUNCTIONS
     SoScale2UniformDragger *  SoScale2UniDragCreate()
	  Constructor.

     const SoNodekitCatalog *  SoScale2UniDragGetClassNkitCat()
	  Returns an SoNodekitCatalog for this class

     SoType		       SoScale2UniDragGetClassTypeId()
	  Returns type identifier for this class.

DRAGGER RESOURCES
     Resource:	       scale2UniformScaler
     Part:	       scaler
     Appearance:       white outline of square with photo-corner shapes at
     vertices. Lies within plane of motion
     Description:      picking this initiates the scaling

     Resource:	       scale2UniformScalerActive
     Part:	       scalerActive
     Appearance:       yellow version of scaler, but with an extra yellow
     surrounding box
     Description:      displayed instead of scaler while in motion

     Resource:	       scale2UniformFeedback
     Part:	       feedback
     Appearance:       thin purple 3-D crosshair
     Description:      shows center of scale when still

     Resource:	       scale2UniformFeedbackActive
     Part:	       feedbackActive
     Appearance:       thin, slightly brighter purple 3-D crosshair
     Description:      shows center of scale while in motion
