I am running this by the list first, before I try it myself to get feedback. I
will try it on my machine then post results.  Once again, I am a green C coder,
and thus, am just making these attempts based on googled optimization

I have seen that it is advised to NOT make function calls within loops as they
add to overhead, so I am proposing to move the function:
 determineSide(POINT2D *seg1, POINT2D *seg2, POINT2D *point)
into the calling function:
point_in_ring(POINTARRAY *pts, POINT2D *point)

since it is only a one line function anyhow, and should not muddy up the code.

Finding the occasional straw of truth awash in a great ocean of confusion and
bamboozle requires intelligence, vigilance, dedication and courage.  But if we
don't practice these tough habits of thought, we cannot hope to solve the truly
serious problems that face us -- and we risk becoming a nation of suckers, up
for grabs by the next charlatan who comes along.
-- Carl Sagan, "The Fine Art of Baloney Detection," Parade, February 1, 1987
