During a partial display list build, we rebuild display items for all frames that intersect with a dirty rect. It should be possible to reuse old display items "in place" for frames that are not modified, and avoid the cost of building a new display item.
This is potentially quite challenging, since display items are currently stored in a single-linked list, and can only exist in one list at the time.
