That's very interesting!  Could you post some code which shows this 
performance regression?  It seems there's a big hole in the 
performance test suite if we're able to regress by 10x and not notice 
it. :|  Alternatively, I guess running cairo-trace from 1.9.2 on your 
app when it's running its self-test might work as well.
