Generating colour bars with minimal resources

[ppppenguin]

I've been mucking around with some of the deisgn and seeing how much resource it uses. Quite encouraging. About 40 macrocells for a 17 bit DTO and all the phase shifting logic to give the different vector angles. Then the really nice result. Unless I've overlooked something an 8 bit input, 8 bit output sine function is only using 16 macrocells. Tempts me to try 10 in, 10 out.
