Also, I have a hypothesis that since LCD displays are grids of square
pixels, they show horizontal and vertical lines very sharply, making
blocking artifacts stand out more.

I'm hesitant to use these, but I'll take it into consideration and try a
test with fairly conservative values for lumi_mask and dark_mask. In a
side-by-side comparison with a non-masked encode, the loss of contrast
is definitely noticeable and detracts from overall impression of quality.

I don't want to use any complexity masking because, from what I can tell
by reading the previous Doom9 comparisons, accurately rendering complex
scenes is a major criterion.

Thanks,
