 It would be interesting to extend the grass vector model to be able to
 construct curves for using them to create real circular buffers instead of
 approximating them using several vertices.

 I just was wondering - isn't it more effectice saving a buffer using one
 vertice and a "curved line" than using several points and approximate the
 circle.

 An appproximated buffer could still be in the data - only newly calculated
 buffers are more correct then.
