        Tests that progress bars honor insets in different L&Fs.
        Different L&Fs render the progress bar differently, and may or may
        not have a different colored background around the progress bar,
        and may or may not draw a border around the bar+background.
        The progress bars should be of equal width and the progress
        rendering line/bar should not extend past/overlap any border.
