SoAntiSquish — transformation node that undoes non-uniform 3D scales

SoGLRenderAction,SoCallbackAction,SoGetBoundingBoxAction,SoGetMatrixAction,SoRayPickAction
          Appends the current transformation with a new matrix to create an unsquished result.

       This node removes nonuniform 3D scaling from the current  transformation  matrix  when  traversed  by  an
       action.  It  is  used  by  draggers  such as the SoTrackballDragger that need to stay uniformly scaled no
       matter where they are located in the scene graph.

       The magnitude of the new scale is determined by the current transformation matrix and the  sizing  field.
       This node does not change the translation or rotation in the matrix.

SoSFEnumsizing
          Determines  which of the algorithms enumerated by the type Sizing will be used to select the new scale
          when the x,y, and z scales are not equal.

     SoSFBoolrecalcAlways
          If recalcAlways is TRUE, this node calculates its unsquishing matrix every time it  is  traversed.  If
          FALSE, then this only occurs during the first traversal folllowing a call to recalc().

SoAntiSquish()
          Creates an anti-squish node with default settings.

     staticSoTypegetClassTypeId()
          Returns type identifier for this class.

     voidrecalc()
          Sets a flag so that the next time the node is traversed, it will recalculate its unsquishing matrix.
