I have thought about doing that and I think that is
the way I will have to go.  I'm confused with how to
extract elements from the vector returned by
gimp-path-get-points.  I thought I understood that
(vector-ref vector k) was the way to pull the k-1
element from the vector, but when I input (vector-ref
'#(1 1 2 3 5 8 13 21) 5) I just get an errobj on
vector-ref.  What do I need to do to be able to
extract a value from the result of
(gimp-path-get-points image path)?
