[Open-graphics] ATI and Nvidia raise the bar?

[Dieter]

So ATI and Nvidia now have noise and sharpness filters.
Perhaps I missed it, but I didn't see anything about whether this
is done in hardware or in the driver.  I also haven't seen an
explaination of exactly what this "twinkling" is and what causes
it.
