 |
 |   Description:
 |      This file defines the jack dragger class, so named because
 |      with the default geometry, it looks like the children's toy.
 |      This dragger allows you to perform rotations,uniform scales
 |      and translations, all in one spiffy gadget.
 |
 |      Translation is done with a dragPointDragger, rotation with a 
 |      rotateSphericalDragger, and scaling with a scaleUniformDragger.
 |
 | NOTE TO DEVELOPERS:
 |     For info about the structure of SoJackDragger:
 |     [1] compile: /usr/share/src/Inventor/samples/ivNodeKitStructure
 |     [2] type:    ivNodeKitStructure SoJackDragger.
 |     [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"); ).  
 |
