Aha, I didn't know about that, but I'd be very surprised if nobody had done this
before in some form! Tim's method is similar, but he's picking random starting
points within the bounding box from which to fire test rays, whereas I'm
looping over a grid of starting points.

It would, as you say, be interesting to see the differences. I shall
investigate. :)
