  \brief The SoTransformer2Dragger provides geometry for translation, scaling and rotations.
  \ingroup draggers

  \DRAGGER_DEFAULT_SCREENSHOT


  ![](http://doc.coin3d.org/images/Coin/draggers/transformer.png)


  Translate the dragger by clicking and dragging any of the
  (invisible) sides. Translation will default be done in the plane of
  the side the end-user selected. The user can hold down a \c SHIFT
  key to lock translation to a single of the axes in the plane. By
  holding down a \c CTRL key instead, translation can be done along
  the plane's normal vector.

  Scaling is done by dragging the corner cubes. By default, uniform
  scaling will be done. Hold down \c SHIFT before selecting any of the
  corners to do non-uniform scaling. Uniform scaling towards a
  corner-point can be accomplished by holding down \c CTRL before
  clicking and dragging one of the cubes.

  Rotation is done by dragging any of the 6 end-markers of the axis
  cross. The initial drag direction decides which orientation the
  rotation will be done in. Hold down \c SHIFT to do free-form
  rotation around the sphere instead.


  This is a big and complex dragger which needs a fair amount of
  proper documentation when provided in end-user applications. If what
  you are trying to accomplish in your application does not really
  demand most of the features of this dragger, you are advised to
  investigate whether or not any of the less complex draggers can
  fulfill your requirements -- so you can provide an as simple as
  possible user interface to your end-users.


  For the application programmer's convenience, the Coin library also
  provides a manipulator class called SoTransformer2Manip, which wraps
  the SoTransformer2Dragger into the necessary mechanisms for making
  direct insertion of this dragger into a scenegraph possible with
  very little effort.

// FIXME, bugs or missing features (pederb, 20000224):
// o some feedback is missing (mostly crosshair)
// o detect if disc or cylinder rotator should be used (disc-only right now)
//
// Also the translation feedback is a bit different from OIV. Coin
// always places the feedback axes at the center of the face being
// translated. OIV places them at the picked point. I think our
// strategy is better, since when switching between constrained
// translations and unconstrained translation, the OIV feedback axes
// can easily be positioned outside the face being dragged.
//
// MATRICES AND SPACES:
// There are many matrices and spaces that can take some time to get
// understand. The matrices calculated are:
//
// localToWorld = motionMatrix * draggerToWorld
// worldToLocal = worldToDragger * motionMatrix^-1
// draggerToWorld = worldToDragger^-1
//
// localToWorking = surroundScaleMatrix^-1
// workingToLocal = surroundScaleMatrix
//
// workingToWorld = surroundScaleMatrix * localToWorld
// worldToWorking = worldToLocal * surroundScaleMatrix
// 
// boxPointInWorldSpace = p * surroundScaleMatrix * localToWorld
// worldPointInBoxSpace = p * worldToLocal * surroundScaleMatrix
