| For large documents the linear search for the first link that is on a
| certain page is really slow. Because of this scrolling becomes slow
| whenever the page changes.
|
| Replace the linear search with a search in a binary tree populated with
| the first link on each page and the corresponding GtkTreePath. This way
| a specialized binary tree lookup can be used to find the closest
| matching link and select that in the treeview.
