CapabilitiesTest demonstrates the
different buffering capabilities available for the machine on which it
is run.
DisplayModeTest shows a Swing application that uses 
passive rendering. If full-screen exclusive mode is available,
it will enter full-screen exclusive mode. If display mode changes
are allowed, it allows you to switch between display modes.
MultiBufferTest enters full-screen 
mode and uses multi-buffering through an active render loop.
