Ok, I'll do this. You can try it for yourself after I separate them,
but it seemed to me like the bounding box was by far the bigger win.
This surprised me somewhat as I expected the world map to hit the
coincident point check a lot - and it does - but with hindsight, it
wasn't going to make as much of a difference because rendering and
qsort dominate the profile for that test.

I'll try that, and all of Carl's suggestions too, thanks for the encouragement.
