The test bitfile provided is a fixed video pattern generator.
Patterns are output through the video encoder to both the S-Video and
RCA ports and can be displayed on the LCD monitors. To test your design,
connect the RCA video output of a board running this bitfile to the
RCA video input of a board running your design.

Settings are configured via the switches as follows:

	SW9:

	global reset

	SW2:

	draws a thin border around the image

	SW9:

	bit 1:		0		=>	normal operation
			1		=>	camera bypass (does not work properly)
	bit 2:		0		=>	487 active lines
			1		=>	507 active lines

	bits 7-3:	00000		=>	thin horizontal lines
			00001		=>	thin vertical lines
			00010		=>	color bars
			00011		=>	static green->pink gradient
			00100		=>	dynamic green->pink gradient
			00101		=>	red apples (you like them apples?)
			00110		=>	blue apples (you like them apples??)
			00111		=>	3-input cellular automata (0-255)
			xxxxx		=>	undefined (black)
	bit 8:		(unused)

	SW6:

	increments the cellular automaton rule displayed

	SW4:

	decrements the cellular automaton rule displayed

	7-segment display:

	shows the current mode or operation
