Tell the display that at the next draw call (typically the next tick) that
it must redraw all of the blocks for the background and can't use a
buffered image.
This method is called in the constructor of a main frame so that the
GameSetup class will be able to communicate with the frame that the
game is being played in.
If this returns true, the drawing routine will use an optimization of
drawing the images for all the blocks once to a large image and just
putting up that image as long as the player hasn't changed screens.
