DESCRIPTION
     SoScaleUniformDragger is a simple dragger that scales uniformly in all 3
     dimensions when dragged 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
     Resources section of the online reference page for this class. You can
     change the parts in any instance of this dragger using

Page 3

SoScaleUniformDragger(3IV)

     SoDraggerSetPart().

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

DRAGGER RESOURCES
     Resource:	       scaleUniformScaler
     Part:	       scaler
     Appearance:       8 small white cubes at the corners of a larger 2x2x2
     cube.
     Description:      picking this initiates the scaling

     Resource:	       scaleUniformScalerActive
     Part:	       scalerActive
     Appearance:       yellow version of scaler, but with extra yellow box
     connecting corners
     Description:      displayed instead of scaler while in motion

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

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