/**
* The test enters fullscreen mode (if it's supported) and then tries
* to switch between display moes with different depths and dimensions
* while doing both rendering to the screen (via a VolatileImage)
* and Swing repainting just to make things more chaotic.
*
* The procedure is repeated TEST_REPS times (3 by default).
*
* Don't pay attention to what happens on the screen, it won't be pretty.
* If the test doesn't crash or throw exceptions, it passes, otherwise
* it fails.
