Apologies for the oversight, I've added you to the pixman group.

There is less calculation, but the noise matrix takes up cache space
(about half a modern CPU's L1) and hence increases memory pressure. The
actual performance relationship is probably hardware dependent, but on
my laptop doing a quick check with patched lowlevel-blt-bench:
- Bayer is ~8% faster
Is the "blue noise" version actually slower than the Bayer? Seems to be
doing a bit less calculation but it reading the array of weights. The
removal of the need for the pattern offset seems like a win.

Hey Matt,
Inkscape would love to see Basile's dithering patches included. Our
testing shows that they make a huge quality difference for our users;
this solves a critical need.
Mc and I have done some preliminary investigation into how to plumb this
into Cairo, and would love to hear your review
I'm not sure how, but I badly broke the formatting on that email -- my
apologies. Below is the previous email formatted as intended.

We don't have the destination bpp when we compute the gradients. Søren

How difficult is it to just make the gradients use dithering, so they
produce 8-bit (or whatever) results directly but with the dithering pattern
in them?
What other operations would need dithering (a large blur comes to mind,
also zooming way in on an image in bilinear)?
I think the blue noise l
I forgot to mention two things:
- Enabling dithering makes processing much slower, since it forces the
wide pipeline to be used (and some optimisations are disabled). This
could be solved through the use of fast paths where needed (e.g. when
blitting images from an equal or lower bits-per-pixels
I am resubmitting for review and inclusion my series of patches on
dithering from October, which I ended up not having the time to finish
then. There are only a couple changes to make the patches compatible
with the recently added floating point formats, and I have also added a
dithering matrix ba
