  The user can resize and rotate the Shape named "SHAPE" in the Nodes.
  In addition to the normal features of the RotatingTool, the SpotRotatingTool
  shows a handle at the <a>Part.rotationSpot</a>, which is also at the <a>RotatingTool.rotationPoint</a>.
  The user can drag that handle and thereby move the rotationPoint and the <a>Part.rotationSpot</a>.
  When the handle is inside the rectangular area of the <a>Part.rotateObject</a>,
  the Spot is purely fractional.
  When the handle moves outside of the object's rectangular area, the spot
  will be at the edge of the rectangle plus an offset.
