If the secondary direction of alignment is not null and is not parallel to the primary direction the axis named axis_2 is rotated as much as possible to be aligned to secondary direction.
If the secondary direction of alignment is null the axis named axis_2 is rotated as much as possible to be realigned to its old direction, if this is impossible the remaining axis is used.
@param primary the primary direction of alignment.
