This test shows the ability to create Frames, Windows and Canvases
with a GraphicsConfiguration.
The test should show a number of windows with RGB stripes according
to the number of the GraphicsConfigurations for each screen.
The window also contains text which displays the size of the screen
and the output GraphicsConfiguration.toString().
The test passes if every screen displays at least one such window.
