NBA Fastbreak VPW flickers with new PWM code #280

@vbousquet Lamps now flicker with the new PWM wiring/implementation

Had a look: this is caused by the initial 8 step WPC GI fix (not PWM implementation). At the begin of the ball, this code leads to a value between 4 and 5, in turns doing the flicker (since it is rounded to an int and flickers in between 4 and 5). It's difficult to fix since the old code was also wrong (most table would just discard intermediate GI line since the value were not reliable). I would say that the way is to move forward and use the PWM code path. Will get in touch with VPW to see how much work this would need

Its a bit better now with the newer bulb code.
