drawFloatFrame for QtQuick menus
Review Request #114271 - Created Dec. 3, 2013 and submitted
drawFrameMenuPrimitive is entered with a null QWidget if a QQuickMenu is rendered. By handling this case we get the menu to render with a frame. Unfortunately we cannot render the widget background as that really needs a non-null QWidget and we also do not yet get shadows.
I'm not sure whether this can affect other areas if QWidget is null.
