The test uses a 100x100 pixels image as a splash screen image. It then 
calls the GraphicsDevice.getDisplayMode().getWidth/Height() methods and 
expects to find the splash screen in the geometrical center of the 
screen (using SplashScreen.getBounds()). I.e. the screen insets are ignored.

Given that the tests pass on Windows, Linux, and Solaris, it makes sense 
to implement the same behavior on Mac OS X as well.
