     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.)
