False, Cairo itself is all fixed point/integer math, however their API
expose float point parameters, which are converted to fixed
internally. Using soft-float here may help, since we'll get no TRAPs
to kernel do it for us in software. But being fixed point doesn't make
things fast on its own.

Carl (cairo guy) said that he was taking care about API, not the core,
so he did the whole thing naively, however correctly, and will
optimize later... since Carlos (nokia) did give him a 770 in order he
can test it, we may expect something great really soon.
