Clocked Video Output slave control not functioning

Beautiful! I got it working in two tries.

Once you confirmed the documentation was correct that there are 19 registers, and not 18, I implemented that and stuck with it.

I was setting back porch values (from the wizard) in the blanking setter functions. Oops. This was causing flicker.

Register number 3 is a hot register with only one bit active at any given time. So it was returning powers of 2 only. I now have my getter take the log_2 of the hot register value to correctly detect the currently active mode.

Yay!
