 * To do:
 *   - Test that nothing happens if the row is fully visible.
 *   - The tests are dependent on the theme/font (size measurements,
 *     chosen paths).
 *   - Convert to proper GTK+ coding style.
 *   - Briefly test scrolling in tree stores as well.
 *
 * Important:
 *   - For tests with "mixed height" models, you must ensure that
 *     there are only two heights used in total and that the rows with
 *     height A and B are strictly alternating.  The model creation
 *     functions already do this for you, but take this into account
 *     when you write a unit test that adds rows to such a created
 *     model, you must follow this rule otherwise things will break.
