pretty easy & secure to implement a coordinate array directly instead of a vector, so it's worth trying.

The STL vector implementation is about as good as you can get

FWIW
I did a massive rewrite inlining all of the Coordinate and CoordinateList
and put the moveto() in all of the low level functions and only got a 30-40%
speedup.  We are looking for an ORDER of MAGNITUDE speedup so I
didn't bother to report my results.

See my earlier post for what I think we need to do to get the BIG BOOST
