Thanks for confirming-

Sure, I'm game with curved labels as well. For those it would
be interesting to have in the test some place where the roads
are really curved (with 90° bends or something).
Something like this:
http://maps.trimet.org/?zoom=6&lat=672441&lon=7637762&layers=B0FTTFF

Out of this test we could also add a slide comparing labelling
by different engines (so the visuals instead of the performance).
Would add an interesting extra to talk about, as better labelling
is usually more expensive as well.

Cheers
