 |   $Revision: 1.1.1.1 $
 |
 |   Description:
 |      This file defines the drag point dragger class.
 |
 | NOTE TO DEVELOPERS:
 |     For info about the structure of SoDragPointDragger:
 |     [1] compile: /usr/share/src/Inventor/samples/ivNodeKitStructure
 |     [2] type:    ivNodeKitStructure SoDragPointDragger.
 |     [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:
 |
 |  dragPointXTranslatorTranslator        - xTranslator.translator
 |  dragPointXTranslatorTranslatorActive  - xTranslator.translatorActive
 |  dragPointYTranslatorTranslator        - yTranslator.translator
 |  dragPointYTranslatorTranslatorActive  - yTranslator.translatorActive
 |  dragPointZTranslatorTranslator        - zTranslator.translator
 |  dragPointZTranslatorTranslatorActive  - zTranslator.translatorActive
 |
 |  dragPointYZTranslatorTranslator       - yzTranslator.translator
 |  dragPointYZTranslatorTranslatorActive - yzTranslator.translatorActive
 |  dragPointXZTranslatorTranslator       - xzTranslator.translator
 |  dragPointXZTranslatorTranslatorActive - xzTranslator.translatorActive
 |  dragPointXYTranslatorTranslator       - xyTranslator.translator
 |  dragPointXYTranslatorTranslatorActive - xyTranslator.translatorActive
 |
 |  dragPointXFeedback                    - xFeedback
 |  dragPointYFeedback                    - yFeedback
 |  dragPointZFeedback                    - zFeedback
 |
 |  dragPointYZFeedback                   - yzFeedback
