 |   $Revision: 1.1.1.1 $
 |
 |   Description:
 |	This file defines the handle box dragger class.
 |
 | NOTE TO DEVELOPERS:
 |     For info about the structure of SoHandleBoxDragger:
 |     [1] compile: /usr/share/src/Inventor/samples/ivNodeKitStructure
 |     [2] type:    ivNodeKitStructure SoHandleBoxDragger.
 |     [3] The program prints a diagram of the scene graph and a table with 
 |         information about each part.
 |
 |  The following parts in this dragger are created at construction time.
 |  'ResourceName' corresponds to the name of the default geometry for the
 |  part. The dragger's constructor gets the scene graph for 'ResourceName'
 |  by querying the global dictionary ( SoDB::getByName("ResourceName"); ).  
 |
 |  Resource Name:                           Part Name:
 |
 |  NOTE: for the translators and extruders, 
 |        numbering refers to a cube-face:
 |        1=top,2=bot,3=lft,4=rit,5=fnt,6=bak
 |
 |	handleBoxTranslator1               - translator1
 |	handleBoxTranslator1Active         - translator1Active
 |      (ditto for translator2-translator6)
 |
 |      handleBoxExtruder1                 - extruder1
 |      handleBoxExtruder1Active           - extruder1Active
 |      (ditto for extruder2-extruder6)
 |
 |  
 |  NOTE: for the uniform scalers, 
 |        numbers refer to a corner: 
 |        1=+x+y+z,  2=+x+y-z, 3=+x-y+z, 
 |        4=+x-y-z,  5=-x+y+z,  6=-x+y-z, 
 |        7=-x-y+z, 8=-x-y-z
 |      handleBoxUniform1		   - uniform1
 |      handleBoxUniform1Active            - uniform1Active
 |      (ditto for uniform2-uniform8)
 |
 |  NOTE: for the arrows, numbering refers
 |        to cube-face they point out from:
 |        1=top,2=bot,3=lft,4=rit,5=fnt,6=bak
 |  
 |      handleBoxArrow1                    - arrow1
 |      (ditto for arrow2-arrow6)
 |
