Copies text, tags, and pixbufs between start and end (the order of start and end
doesn’t matter) and inserts the copy at iter.
Used instead of simply getting/inserting text because it preserves images and tags. If start and end are in a
different buffer from this, the two buffers must share the same tag table.
Implemented via emissions of the insert_text and apply_tag signals, so expect those.
