/**
* gimp_image_arrange_objects:
* @image: The #GimpImage to which the objects belong.
* @list: A #GList of objects to be aligned.
* @alignment: The point on each target object to bring into alignment.
* @reference: The #GObject to align the targets with, or #NULL.
* @reference_alignment: The point on the reference object to align the target item with..
* @offset: How much to shift the target from perfect alignment..
*
* This function shifts the positions of a set of target objects, which can be
* "items" or guides, to bring them into a specified type of alignment with a
* reference object, which can be an item, guide, or image. If the requested
* alignment does not make sense (i.e., trying to align a vertical guide vertically),
* nothing happens and no error message is generated.
*
* The objects in the list are sorted into increasing order before
* being arranged, where the order is defined by the type of alignment
* being requested. If the @reference argument is #NULL, then the first
* object in the sorted list is used as reference.
*
* When there are multiple target objects, they are arranged so that the spacing
* between consecutive ones is given by the argument @offset.
