The Rotation tab allows one to rotate the tiles depending on the row and column position. Rotation center is used as the center of rotation. See the Tile Tricks section for examples of using a shifted Rotation center. The rotation is specified in degrees. The following options are available:
Angle: Rotate by this amount around the Rotation center. A random factor can also be added.
Alternate: The rotation alternates between being added and subtracted.
Cumulate: Rotation is cumulative.
