Yes, thats what I thought would be best, too.

Sure, but today trapezoids seem to be the best way to push aa coverage
values to the xserver.
When new interfaces come up, I'll adopt to a newer cairo release.

I only heard once that something like RLE spans are planned for
render,  its a welcome change.
I was never a big fan of trapezoids, and all the complexity and
inefficiency caused by them.
Does the discussion mainly happen on IRC?

Thanks for beeing that helpful :)

Thanks again, Clemens
