\item[Rotation center] Usually this parameter is zero, and the rotation search
range is $+/-$ \textit{Rotation search radius}. Otherwise, it shifts the rotation search range to the area of angles between (\textit{Rotation center} $-$ \textit{Rotation search radius}) and (\textit{Rotation center} $+$ \textit{Rotation search radius}).
\item[Maximum angle offset] The total accumulated amount of rotation is unlimited
if this is 90 degrees. If it is under 90, the total amount of rotation is
limited by the given maximum angle.
\item[Rotation settling speed] This parameter determines how fast the accumulated
