51 * The test enters fullscreen mode (if it's supported) and then tries
52 * to switch between display moes with different depths and dimensions
53 * while doing both rendering to the screen (via a VolatileImage)
54 * and Swing repainting just to make things more chaotic.
55 *
56 * The procedure is repeated TEST_REPS times (3 by default).

58 * Don't pay attention to what happens on the screen, it won't be pretty.
59 * If the test doesn't crash or throw exceptions, it passes, otherwise
