Nice job.
I'm still interestd in using the magic-number approach for rounding of extents, when we figure out how to do it in cairo. But that also would mean requiring all the configure magic and all :(. Well, maybe we can expose _cairo_lround() publicly. /me knows Carl won't like that... > > In my testings, this didn't affect the timetext test much > > Well, according to these profiles: > > http://folks.o-hand.com/jorn/pango-benchmarks/210-softfloat/pango.txt > http://folks.o-hand.com/jorn/pango-benchmarks/210-softfloat/pango-cairo.txt > > your improvement should make a large difference on the 770.

Numbers for Pango 1.15.0 vs. 1.15.1 would be interesting.
