QBoxLayout::setGeometry would not respect the widget min/max width
When calling heightforWidth after a geometry change, the width actually used could be outside the widget's width bounds. The height could then be smaller than needed to fit the widget's contents resulting in a clipped widget being drawn. Auto-test included. Reviewed-by: Olivier Task-number: QTBUG-7103
