SoTrackballDragger is a ball wrapped in three circular stripes. The stripes are oriented like wheels that
       spin around the x, y, and z axes. Drag the stripes to rotate the trackball around those axes. You do  not
       have  to  hit  the  lines; pick anywhere within the stripe's outline. To rotate the trackball freely in 3
       dimensions, click the area between the stripes and then drag. An invisible but pickable sphere  initiates
       this dragging. If the mouse is still moving when you release it, the trackball will continue to spin.

       Press the <Control> key to scale the trackball uniformly instead of rotating.

       Press the <Shift> key and the useraxis appears; this is a draggable axis with an extra stripe around it.
       Moving  the  mouse  along the surface of the sphere drags the 'pole' of the axis. Release the <Shift> key
       and the user axis remains; drag the new stripe for constrained rotation around the user axis. To make the
       user axis disappear, press <Shift> and drag the pole to where two of other stripes intersect. This aligns
       the user axis with a primary axis, at which point the user axis disappears.

       As you drag the trackball, it updates its rotation field, or its scaleFactor field if the  <Control>  key
       is down. As with all draggers, if you change the fields the dragger moves in response.

       Remember:  This  is  not  an  SoTransform!.  If you want to move other objects with this dragger, you can
       either:

       [a] Use an SoTrackballManip, which is subclassed from SoTransform. The manipulator creates one  of  these
       draggers  and  uses  it  as  the  interface  to  edit the manipulator's fields. (see the SoTrackballManip
       reference page).

       [b] Use field-to-field connections to connect the fields of this dragger to those of any SoTransformation
       node.

       You can change the parts in any instance of this dragger using setPart(). The default part geometries are
       defined as resources for this SoTrackballDragger class.  They  are  detailed  in  the  Dragger  Resources
       section  of  the  online  reference  page for this class. You can make your program use different default
       resources for the parts by copying the file /usr/share/data/draggerDefaults/trackballDragger.iv into your
       own directory, editing the file, and then setting the environment variable SO_DRAGGER_DIR to be a path to
       that directory.

          If the mouse is moving while you release it, the trackball will continue to spin afterwards. These two
          methods will query and set whether this feature is turned on or off. By default, the animation feature
          is turned on.

       SoTrackballDragger — striped ball you can rotate or scale uniformly by dragging with the mouse

       Unlike  most  multi-function  draggers,  SoTrackballDragger  is  not  a compound dragger made up of other
       draggers that perform its smaller tasks. This is not  because  it  was  inappropriate,  but  because  the
       trackball was written before implementation of the methods that take care of synchronizing multiple child
       draggers.  The  younger  SoCenterballDragger is similar in form to the trackball, but the centerball is a
       compound dragger.
