Right. Updated.

I thought of that, but does it really matter? I tried various values of
spuaa, and compared with the original: looking carefully with xmag, it is
possible to see they are not exactly the same, but neither looks better than
the other. After all, there is no "correct" scaling (especially not without
gamma correction), it just has to look nice and be fast.

I also peeked at the source code for Cairo, which is a notable user of
premultiplied values: they do not seem to bother with that issue at all.

Regards,
