Probably.  Do you know an efficient way to calculate the bounding box of
a spline? 

I think walking along a flat path is nearly as expensive as tesselating,
and not necessary, imho, because the information we need will be
calculated during tesselation anyway.

But maybe you're right and it is better to have a clean interface, even
if that makes the code a little bit slower.
