+ * Title: Bug 290650 - [Layout] If a composite with a FillLayout (with marginWidth != 0)
+ * contains a widget which could expand depending on a fixed width or height, than computeSize()
+ * doesn't calculate the expanding size correctly.
+ * How to run: launch snippet and observe size of Text widgets
+ * Bug description: One widget is only one line in height when it should be two
+ * Expected results: Both widgets should be 2 lines in height
+ * GTK Version(s): GTK2.x, GTK3.x
