Add test for bug 111500

Browse Source 
This test is constructed in such a way that it breaks when you
(currently!) do not trigger a size-request from validate_visible_area.
Especially row expansion appears to have a need for this currently.

* - 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.
