                of certain icon functionality -  background transparency/opacity
                of the icon, scaling etc.
                Clicking on each button brings up a window displaying the graphic
                that should appear in the corresponding icon.
                Click on each button, minimize the resulting window, and check that
                the icon is displayed as the test name indicates.
                On Win32, icons should also be displayed correctly in the title bar.
                If all the test pass, then this test passes, else fail.
