We certainly intend it to be usable for interactive and animated 2D
graphics. We're not done yet, but some people are having fun with it

Cairo does not guarantee a pixel-level accurate API.
For example, take a look at the differences in the following
These were rendered with cairo, but some with the glitz backend and some
with cairo's software backend (pixman). The results are similar in all
cases, but obviously not pixel-accurate. And those slightly less-precise
results from glitz come at speeds that are up to hundreds of times
David and Peter's presented a paper at the USENIX Annual Technical
conference this year that details the speedups possible with glitz.
I hope one of them will reply here with a pointer to a full-text version
of that paper.
