Panoramix video filter by Cédric Cocquebert.

+ temporarily re-enable vout-filter until video-filter is updated

I include this so that it can get some testing and debugging, but it has some issues:
* Several coding style / indentation problems that make the code quite hard to read
* Use of config_Get/config_Put instead of vars
* In my tests, it crashes as soon as bz-length is not == 0, which basically makes the attenuation effect inoperant

THANKS
