Do you mean in the API? Or for internal computations?

I have a couple of branches improving them:
- http://cgit.freedesktop.org/~ranma42/pixman/log/?h=wip/radial-float2
  (almost ready for merge, I would just like some benchmarking on
  non-x86_64 architectures)
- http://cgit.freedesktop.org/~ranma42/pixman/log/?h=wip/linear2
  (it probably won't compile on 32 bits architectures, as it uses int128_t.
  I'm working on getting wide-ints (and atomics etc etc) from cairo in pixman,
  but there is still some work to do)

I should be working on this, too, I know...

All of these are actually changes/fixes in pixman, not cairo.
I'm quite sure they should belong to some todo/roadmap for pixman (and
this is why I'm sending this mail to the pixman mailing list, too), but I
don't think that cairo 1.12 should be blocked by them.
