Nyall Dawson 1537d393e3 Add framework for retrieving the temporary results of a in-progress
edit operation on an annotation item

This is used for the item to return a representative geometry
of what the item would look like if the operation were to be
applied. It's used to generate a rubber band showing a preview
of the modification during interactive editing operations on
an annotation item.
