      3 * Almost all of the image decoding reftests require the display to be in
      4 * 24-bit color mode, or else the rendered images will have subtle color
      5 * variations and will fail.
      6 * The Windows test boxes used to have a tendency to flip to 16-bit color mode,
      7 * so this test will explicitly check the color depth to make it more obvious
      8 * when the requirement is not met. (See bug 414720.)
      9 * 24-bit is only a minimum, allow higher values too. (See bug 458847.)
