* - The tests are dependent on the theme/font (size measurements,

* - 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
