//
// It exists only to be measured correctly. QPushButton computes its size hint from its
// text and icon and ignores a layout set on it, so a button carrying a face of widgets
// would be sized as if it were empty and clip everything in it. This asks the layout
// instead, and then lets the style add what the button's own frame needs.
