  227.             The Transform Direction sets which way or direction a layer is
  228.             rotated. The Normal mode will rotate the layer as one might
  229.             expect. If a layer is rotated 10 degrees to the right, then the
  230.             layer will be rendered as such. This behaviour is contrary to
  231.             Corrective rotation.
  232.           </p>
  233.               <p>
  234.             Corrective Rotation is primarily used to repair digital images
  235.             that are not straight. If the image is 13 degrees askew then you
  236.             need not try to rotate by that angle. By using Corrective Rotation
  237.             you can rotate visually and line up the layer with the image.
  238.             Because the transformation is reversed, or performed backwards,
  239.             the image will be rotated with sufficient angle to correct the
  240.             error.
