Not without tesselating.  For example even if all the
base points of a spline are inside, that does not
necessarily mean that the whole spline is inside.

The only workaround would be to ask the _user_ for the
bounding box of the path.  Which would mean that we
have exactly one shape for one path, which is a little
bit lame. I want that it is possible to use a graphics
primitive _or_ a shape within a container:

  <menu><item "File"/><path "n 0,20 m ..."></menu>
